     TECHNICAL FIELD 
     The present invention relates to reinforcement devices, systems and methods useful for constructing and reinforcing a structure. Specifically, one embodiment of the reinforcement device is an adjustable foundation system for use as reinforcement structural columns, posts and/or supports for a structure, particularly for use in new construction of pole barns and other buildings. The present invention further includes a reinforcement device useful for securing to and stabilizing existing structural posts of a building such as wooden support columns of a post frame or pole buildings. The present invention also relates to a system and method for raising the height of an existing building or structure using a reinforcement device, thereby providing more useful interior space for accommodating large pieces of equipment and/or for providing more storage capacity. 
     BACKGROUND 
     It is, of course, generally known to construct a structure, such as a shed, barn, garage, etc., using wooden posts set into a series of holes dug in the ground to define a perimeter and create the initial frame for the structure. In the case of pole barns, the structural or framing posts are buried in the ground, and often surrounded by dirt, gravel or concrete. However, long-term contact of wooden posts with the ground can lead to post rot of these wood pilings, resulting in potential structural failure, often prematurely. Additionally, many older structures, such as older barns, with wood columns embedded into the ground subject to decay, rotting, and insect infestation, which can affect the overall integrity of the structure. However, it is often desirable to repair older, wood frame structures to maintain their integrity for various reasons including costs, convenience and history. 
     Improvements continue to be made to provide longevity, durability and strength to post frame buildings. The traditional method of repair requires that large holes be excavated within the building next to and/or around each post. A new post is then installed next to the existing post and the posts are bolted together. With this traditional method, there is typically no new foundation installed and no additional uplift protection. Opening up large holes including breaking and tearing out concrete flooring around the existing columns is invasive, labor intensive and costly. Additionally, most traditional repairs will take several days to a week to complete, and can be expensive. 
     For decades, post frame buildings were built all across America that were designed to store equipment and machinery that was much smaller in stature than what is in use on today&#39;s modern farms. As a result, many of these otherwise useful buildings are being removed to make room for new buildings with higher interior clearances to accommodate today&#39;s larger farm machinery. However, razing a structure and building a new one can be time-consuming and expensive. Additionally, many older structures have value, not only historically but may also have sentimental value to the owner. Therefore, a need exists for refurbishing existing buildings by extending existing wood columns to increase the interior space clearance, thereby providing the interior height and space needed for today&#39;s modern farm equipment. 
     Additionally, there exists a need for options to the traditional wood post construction of foundations for new buildings. Replacing traditional wood foundations with easy to use columns made of material able to withstand rot, decay and insect damage that traditional wooden posts are susceptible to, or expand and contract due to freezing and thawing, results in a structure more durable and well-protected against destructive natural forces than the average post frame building foundation. Because each column can be stabilized and adjusted both vertically and horizontally the integrated grade board bracket allows the wall post to interlock. This allows the entire foundation system to be stabilized and minor, if any, post movement occurs when backfilling the excavated holes with concrete, resulting in a solid, precise foundation system. Moreover, the lack of pre-cast concrete posts eliminates the possibility of blow outs that can compromise the integrity of the foundation&#39;s concrete. 
     A need, therefore, exists for improved devices, systems and methods for reinforcing a structure. Specifically, a need exists for improved devices, systems and methods for reinforcing and stabilizing failing structural elements including structural and framing posts quickly and easily. 
     A need further exists for improved devices, systems and methods for providing a reinforcement device for use in constructing an improved foundation for a structure wherein the foundation is resistant to the elements, rot and decay and insect infestation. 
     Additionally, a need exists for improved devices, systems and methods for constructing a foundation using preassembled columns, and the pre-drilled holes which make for simple attachment to boards and planks used in the construction of a foundation for a structure. This saves time and increases labor efficiency. 
     A need further exists for improved devices, systems and methods for constructing a foundation utilizing columns much lighter than traditional wooden posts or precast concrete columns, making lifting safer and easier for the worker and reducing the need for heavy machinery to assist in transportation and installation. 
     Further, a need exists for improved devices, systems and methods for providing a reinforcement device useful in raising the height of an existing structure. 
     Moreover, a need exists for improved devices, systems and methods for reinforcing wooden posts or columns of an existing structure using fewer tools and workers to install the device. 
     A need further exists for improved devices, systems and methods for providing an efficient and time-saving structurally sound repair to failing columns supporting a building. 
     Additionally, a need exists for improved devices, systems and methods for constructing a new structure while further protecting it from future decay and potential insect infestation. 
     A need further exists for improved devices, systems and methods reinforcing and stabilizing a structure utilizing a multi-sided sleeve device for surrounding and reinforcing an existing structural wooden post. 
     A need further exists for improved devices, systems and methods for stabilizing a structure and providing additional uplift and lateral strength to increase the height of an existing structure thereby increasing the useful interior space of the structure. Often minor height loss is due to sagging from the breakdown of wood columns and settlement. 
     Additionally, a need exists for repairing and or straightening sagging walls, and providing improved structural integrity to an existing structure so it can better withstand damage from storms, including potential wind damage. 
     Moreover a need exists for improved devices and systems adaptable for reinforcing a structural element, such as a post for a pole building, have a variety of shapes and sizes. 
     Further, a need exists for improved devices, systems and methods for a structurally sound repair of existing structural columns at a fraction of the cost to replace existing structural elements or even an entire structure.

     In yet another embodiment, the present disclosure relates to a method for creating a foundation for a structure. The method includes the steps of outlining a perimeter of a structure through the excavation of a plurality of holes, providing a height adjustable column assembly comprising, a column body having a top and a bottom, a bracket secured to the top of the column body, a height adjustment mechanism extending above and downward through the bracket within an interior space of the column body, the height adjustment mechanism capable of vertically moving the column body and bracket between any desired height; and, a stabilizer pad secured to an end of the height adjustment mechanism opposite the top of the column body, positioning each height adjustable column assembly within each hole forming the perimeter, wherein the bracket is above ground level and the stabilizer pad is positioned at the bottom of the hole, adjusting each height adjustable column assembly through the height adjustment mechanism to an acceptable level position; and, disposing at least one board on each of the brackets, forming an initial foundation for the structure. 
     In another exemplary embodiment, the present disclosure relates to a reinforcement device useful for securing to and stabilizing existing structural posts of a building such as wooden support columns of a post frame or pole buildings. The reinforcement device has a multi-sided corrugated structure, which is adaptable for engagement with structural posts having a variety of shapes and sizes. Additionally, the present disclosure relates to a system and method for increasing the height of an existing structure, due to sagging from a breakdown of wood columns and settlement, or increasing the height of the entire structure, thereby increasing the useable interior clearance space to accommodate large pieces of equipment. 
     To this end, in an embodiment of the present invention, a device for reinforcing an existing structural element of a building is provided. The device comprises a multi-sided sleeve having an elongated body comprising a longitudinal center section integrally connected along opposing edges to a pair of opposing longitudinal legs or panels having a length the same as the center section.

     DETAILED DESCRIPTION 
     The present disclosure relates to devices, systems and methods for constructing a foundation and replacing the traditional wood and/or precast concrete columns used for supporting a structure, such as a post-frame building. Specifically, the present disclosure relates to improved reinforcement devices, systems and methods useful in the construction of solid, corrosion-resistant foundations for new buildings, including pole or post-frame buildings. The present disclosure also relates to another embodiment of improved reinforcement devices, systems and methods useful for reinforcing and stabilizing existing structural posts of a building, such as existing wooden columns of a post frame or pole buildings. Additionally, the present disclosure relates to a system and method for utilizing a reinforcement device for increasing the height of an existing structure, thereby increasing the useful interior space of a structure to accommodate larger pieces of equipment and machinery and/or to provide additional storage capacity. 
     Now referring to the figures, wherein like numerals refer to like parts,  FIGS. 1-4   a - 4   d  illustrate an embodiment of a reinforcement device  100 , specifically, a height adjustable column assembly having a height adjustment mechanism therein.  FIGS. 5-10  illustrate additional embodiments of a reinforcement device  300 ,  400 , specifically a height adjustable column assembly using alternative versions of a height adjustment mechanism, respectively.  FIGS. 11-13  illustrate a bracket and grade board combination useful in constructing the foundation for a structure.  FIGS. 14-16  illustrate a reinforcement device, specifically a reinforcement sleeve useful for stabilizing and strengthening existing columns and/or posts of existing building structures, such as pole barns constructed from wooden posts.  FIG. 17  illustrates an embodiment of the reinforcement device used for lifting an existing structure and increasing the interior space of the structure. 
     Creating a foundation for a structure, particularly a post-frame or pole barn structure  500 , that is resistant to changing weather conditions, rot or decay, and insect-infestation, is vital for the long-term survival of the structure. Additionally, having options away from traditional wood and precast concrete as foundation supports is desirable to meet many of these requirements, and potentially reduce labor and equipment requirements and associated costs. As shown in  FIGS. 1-3 and 4   a - 4   d,  an embodiment of a reinforcement device in the form of a height adjustable column assembly  100  incorporating an embodiment of a height adjustment mechanism  130  is provided for use in the construction of a structure  500 . Alternative embodiments of height adjustment mechanisms  300 ,  400  incorporated into the height adjustable column assembly  100  are shown in  FIGS. 5-10 . 
     The height adjustable column assembly  100  includes a column body  102  having a top  104  and a bottom  106 , a bracket  120 ,  128  at the top of the column body and a height adjustment mechanism  130 . As shown in  FIG. 2 , when used as a foundation column for a structure  500 , the column body  102  of the height adjustable column assembly  100  is placed within a hole  600  excavated in the ground  610  using known techniques to form the perimeter of the foundation  520  for a building structure  500 . The bracket  120 ,  128  of the column assembly  100  remains at or slightly above ground level  610  for receiving and securing boards  505 , also known as planks, grade boards or splashboards, which are secured to the height adjustable column assemblies to create the foundation  520  ultimately supporting the entire structure  500 . 
     As shown in  FIGS. 3, 4 and 4   a - 4   d,  the column body  102  of the present height adjustable column assembly  100  is generally a cage formed from a plurality of reinforcing vertical bars  112 , also referred to as “rebar,” which form an outer perimeter of the cage of the column body  102 , and an interior space  102   a  of the column body. For example, in one embodiment shown in  FIGS. 4 a  and 4 b   , four, evenly-spaced vertical bars  112  form a generally rectangular cage of the column  102 . The top end  112   a  of the vertical bars  112  are welded directly to the underside or undersurface  124   a  of the base  124  of the bracket  120 ,  128  ( FIG. 4 c   ,  FIG. 5  and  FIG. 8 ). The opposing bottom end  112   b  of the vertical bars is secured typically by welding to a reinforcement anchor  114  at the bottom  106  of the column body  102  ( FIG. 4 a   ). It should be understood that although four vertical bars  112  are shown, any number of vertical bars may be used to create the cage structure of the column body  102 . 
     The column body  102  is further strengthened and stabilized by at least one reinforcement anchor  114 , which horizontally spans the interior space  102   a  inside the perimeter of the cage. The reinforcement anchor  114  has generally an X-shape, where each leg  114   a  of the anchor is rigidly connected, such as by welding, to each of the vertical bars  112 . Alternatively, the individual vertical bars  112  of the column body  102  may engage openings  114   b  in the legs  114   a  of the anchor, where the bars can be secured, also by welding ( FIGS. 4 a   - 4   d,    5 ,  6 ,  8  and  9 ). The reinforcement anchor  114  further includes a center opening  114   c  for receiving components of the height adjustment mechanism, for example, the guide tube or cylinder  134 , and the extension rod  135  ( FIGS. 4 a    and  8 ). The reinforcement anchor  114  acts as a brace providing additional strength to vertical bars  112  forming the column body  102  and stabilizes the components of the height adjustment mechanism  130  within the interior of the column body. The reinforcement anchors  114  assist to maintain the integrity of the column body  102  and height adjustment mechanism  130  components as the column body is surrounded by dirt, gravel or concrete after the column assembly  100  is placed in the ground and initially leveled. Although the figures illustrate embodiments with varying numbers of reinforcement anchors  114  positioned in a number of different locations within the column body  102 , it should be understood that any number of reinforcement anchors  114  may be incorporated, as well as positioned at various points within the column body  102 , including at or near the bottom  106  of the column body, and in any location between the bottom and the bracket  120 . 
     The top  104  of the column body  102  includes a bracket  120 ,  128 . The bracket  120 ,  128  is designed to receive and secure boards  505 , such as the splashboards, grade boards or planks to create the foundation  520  of a building  500 , as well as, receive and secure vertical columns  510  used for constructing the walls of the building ( FIGS. 3 and 4 ). As shown in detail in  FIGS. 4 a  and 4 b   , there are at least two embodiments for the brackets  120 ,  128 , depending on whether the bracket is a corner bracket  120 , or a side bracket  128 . The corner bracket  120  includes at least one upright arm  122  connected to a horizontal plate forming a base  124  ( FIG. 4 b   ). The side bracket  128  includes two opposing upright arms  122  connected by the base  124 , essentially forming a U-shape or H-shape bracket ( FIG. 4 a   ). Lower sections  122   a  of the arms  122  are connected, generally by welding, to the vertical bars  112  forming the column body  102 , while upper sections  122   b  of the arms include a plurality of holes  121  for receiving fastening devices for securing the boards and vertical columns placed between the opposing arms. 
     Each upright arm  122  further includes a notch  122   c  on an outer edge of the upper section  122   b  of each arm, the notch adapted for receiving, squaring and levelling a string (not shown) useful in determining the overall squareness and level position of a plurality of the column assemblies  100  after placement of the assemblies in respective holes  600  forming the initial perimeter of the building  500  ( FIG. 2 ). The designated use of the height adjustable column assembly  100 , as either a side wall column  128  ( FIG. 4 a   ) for use in the construction of a long side of the proposed building, or as a corner column  120  ( FIG. 4 b   ) for use in the joining of a corner of the propose building, dictates which embodiment of the bracket  120 ,  128  is needed. 
     As shown in  FIGS. 4 a  and 4 b   , the bracket  128  includes a vertical plate  125  extending downward from the base. The vertical plate  125  further extends and connects between a lower section  122   a  of the opposing arms  122  ( FIG. 4 a   ). At least one integrated side support bracket  126  is disposed on the vertical plate  125  at the base of the bracket. Optionally, two side support brackets  126  arranged, one on each perpendicular connecting side of the base  124  of the bracket, are used for corner placement of boards on the corner bracket  120  ( FIGS. 4 b  and 4 c   ). The side support bracket  126  is designed to receive a board  505 , grade board, splash board or plank, which is used to build the foundation  520  of the building ( FIGS. 3, 4 and 4   c ). Side support bracket  126  may include a vertical centerline in the form of a slot  126   a  used for accurate measurement of column spacing (typically about 8 feet apart) allowing precise placement of building columns when setting out the perimeter of the building  500  ( FIGS. 4 a , 4 b   ). 
     During construction of a new building, after multiple adjustable column assemblies  100  are placed in each of the respective excavated holes  600  around the proposed perimeter of a building, the side support bracket  126  or brackets of each column assembly  100  engage a board  505 , spanning across each of the assemblies ( FIG. 4 ) to begin building the foundation  520 . The column assemblies  100  are leveled through placement of a leveling string (not shown) along each notch  122   c  on the outer edge of each upright arm  122 . A laser level (not shown) is used in conjunction with the leveling string after it is placed in the notch  122   c  to assist in accurately leveling each of the column assemblies  100  after placement. Because each grade board  505  interlocks within the side support bracket  126  of the column assembly  100  thereby providing lateral support, the entire foundation system is stabilized and no post movement occurs when installing structural columns  510  for ultimately supporting trusses  512  of the structure  500  ( FIG. 1 ). The combination of the side support brackets  126  with the grade boards  505  keeps each of column assemblies  100  in position in the excavated hole  600  before the hole is filled with concrete and secured. 
       FIG. 4  illustrates one embodiment of a height adjustment mechanism  130  for use in the height adjustable column assembly  100 . In this embodiment, the height adjustment mechanism  130  is a three component assembly, including: a rod  132 ; a hollow guide tube or cylinder  134  disposed vertically from and connected to an undersurface  124   a  of the base  124  of the bracket  120 ,  128 ; and an extension rod  135 . The rod  132  may have a threaded outer surface  132   a  ( FIGS. 4 a - c   ). Optionally in another embodiment, the rod  133  may have a smooth outer surface  133   a  without threading ( FIG. 4 d   ). The rod  132  passes through a central opening  124   b  in the base  124  of the bracket  120 ,  128 , entering into the interior space of the guide tube or cylinder  134 , which is positioned in line with the opening in the base. The guide tube  134  can have any length, but it is typically about one third to one half the length of the column body  102 . The guide tube or cylinder  134  includes a threaded nut (not shown, but see reference number  403  in  FIG. 8 ) welded at the top of the guide tube where the tube connects to the undersurface  124   a  of the base  124  of the bracket  120 ,  128 . As the rod  132  passes through the opening  124   b  in the base, the threaded outer surface  132   a  of the rod  132  engages with the threaded nut on the top end of the guide tube  134 . Optionally, in another embodiment, rather than a threaded nut at the top of the cylinder  134 , the interior surface of the guide tube  134  itself is threaded for engagement with the threaded surface  132   a  of the first rod  132 . In yet another embodiment, the rod  133  has a smooth, non-threaded outer surface  133   a,  and guide tube  134 , without either the threaded nut or a threaded inner surface, simply telescope together for engagement with the second extension rod  135  ( FIG. 4 d   ). 
     The third component of height adjustment mechanism  130 , the extension rod  135 , is generally a smooth rod having a diameter smaller than that of the guide tube  134 , that is positioned upward through the bottom  106  of the column body  102  and into the interior of the guide tube  134 . The extension rod  135  includes disk-shaped base or foot plate  136  at the bottom of the rod and outside of the column body  102  ( FIG. 4 ). The extension rod  135  further passes through a center opening  114   c  of at least one reinforcement anchor  114 , which assists in stabilizing and holding the extension rod in position. The foot plate  136  may be flat or include an angled bottom, which is configured to engage the floor of an excavated hole, thereby providing resistance when the height adjustment mechanism  130  is engaged to vertically move the column assembly  100 . 
     The present height adjustment mechanism  130  is an improvement and an advantage over other mechanisms in standard foundation columns because it provides the option to adjust the adjustable column assembly  100  on a construction site, with precision, while the assembly is in an upright position and already placed within an excavated hole  600 . Rough height adjustments can be made prior to installation of the adjustable column assembly  100  into the excavated hole  600 ; however final, finessed adjustments can be made through the height adjustment mechanism  130 , even after wet cement is added to the hole. 
     Specifically, operation of the present height adjustment mechanism  130  includes the rod  132  passing through the opening  124   b  in the base  124  of the respective bracket  120 ,  128  for engagement with the guide tube  134 , either through the threaded nut disposed at the top of the guide tube, or through engagement with a threaded interior surface of the guide tube, or, optionally, through non-threaded telescoping engagement between the rod and the guide tube. In one example, using an appropriate tool, such as a screw gun, the rod  132  is rotated downward into the threaded nut  134   a  of the guide tube  134  until it engages with the extension rod  135 , which is positioned upward into the interior space of the guide tube  134 . By rotating or pushing the rod  132  downward into the guide tube, and against the extension rod  135 , the column assembly  100  can be precisely adjusted, up or down, after placement of the column assembly into the excavated hole  600 . Because the guide tube  134  surrounds and protects the rod  132  and extension rod  135  as they connect inside the guide tube from contact with dirt or cement as it is placed within the hole  600  around the column assembly  100 , the height adjustment mechanism  130  can adjust the height of the column assembly even after concrete is poured within the hole and while still wet. After the appropriate adjustments are complete, the rod  132  can then either be removed or cut, and a vertical column  510  for construction of a structure can be secured in the bracket  120  using known fasteners ( FIG. 3 ). Thus, the height adjustment mechanism  130  is useful to accommodate post holes of inconsistent depths and levels, because it permits custom, on-site levelling of the foundation boards  505 , even after surrounding the column assembly with dirt, gravel, concrete or any other securing material. 
       FIGS. 5-7  illustrate another embodiment of a height adjustment mechanism  300  useful in the present column assembly  100 . Specifically, in this embodiment, the height adjustment mechanism  300  includes a single rod  302 , which passes through an opening  124   a  centered in the top of the bracket  128 , as previously described, through interior space  102   a  of the column body  102 , the rod ending in a foot plate  303 . At least one reinforcement anchor  114  is positioned within the column body  102 , such that the single rod  302  passed through the center opening  114   a  of the reinforcement anchor  114  or anchors located within the column body  102 . A set screw  304  and collar  306  combination are positioned below the base  124  of the bracket, the collar having a center opening  306  such that the single rod is vertically slidably within the collar. The set screw  304  is configured for threaded engagement with a side opening  306   b  within the collar  306 . It should be noted the positioning of the set screw  304  and collar  306  combination can be anywhere along the length of the column body  102 ; however, higher placement of the set screw and collar within the column body may provide more convenient access for adjustment once the column assembly  100  is placed within a hole. Additionally, a reinforcement structure, such as a reinforcement anchor  114 , or other form of reinforcement bar can be positioned below the set screw and collar combination, for additional security. After the column assembly  100  is placed within a hole, the height of the column assembly can be made by sliding the assembly up and down along the rod  302 , which has a smooth outer surface. Optionally, the outer surface of the rod  302  may be textured for engagement with the set screw  304 . Once the desired height is reached, the column assembly  100  can be locked into position by tightening the set screw  304  against the rod  302 . This embodiment of the height adjustment mechanism  300  provides easy manual adjustment and setting of the height of the column assembly, eliminating the need for additional tools and equipment. 
       FIGS. 8-9  show yet another embodiment of a height adjustment mechanism  400  useful in the present column assembly  100 . Similar to the height adjustment mechanism  130  described above, this embodiment of the height adjustment mechanism  400  is a three component assembly, including a first rod  402 , a hollow cylinder  404  disposed vertically within the interior of the column body  102 , and an extension rod  406 . As shown in  FIGS. 8 and 9 , the cylinder  404 , is positioned away from, and not connected directly to the bottom or undersurface  124   a  of the base  124  of the bracket  128 . In this embodiment, a threaded nut  403  is at the top of the cylinder  404 , which is used for engagement with a threaded outer surface of the first rod  402 , as previously described. Alternatively, rather than including a threaded nut  403  at the top of the cylinder  404 , the interior or inner surface of the cylinder  404  could be threaded for engagement with the threaded surface of the first rod  402 . 
     This height adjustment mechanism  400  functions in a similar manner to adjust the height of the column assembly  100  as the previously-described height adjustment mechanism  130 . The first rod  402  passes through an center opening  124   b  in the base  124 , where it enters the interior space of the cylinder  404 . With its foot plate  407  at ground level in a hole, the extension rod  406  passes upward through the bottom  106  of the column body  102 , and into the interior space of the cylinder, where it meets with the first rod  402 . As the first rod  402  rotates and pushes against the extension rod  406 , the vertical height of the column assembly  100  can be adjusted up or down to the desired position. As previously described, any number and positioning of reinforcement anchors  114  are provided within the interior  102   b  of the column body  102 . 
     The present height adjustable column assembly  100  is designed to replace the standard wood, concrete, or combination of both, traditionally used as foundation columns in post-frame or pole barn construction. Constructed from any suitable corrosion-resistant material, such as galvanized steel powder coat or plated materials, the present height adjustable column assembly  100  is light-weight (weighing less than 40 pounds) making easily maneuverable and adjustable for placement within an excavated hole  600 , without the need to additional tools or equipment. However, and unlike traditional wooden posts, which can rot and potentially fail, the present column assembly  100  is not susceptible to the elements or insect infestation, nor will the present column assembly expand and contract due to freezing and thawing. Additionally, and unlike traditional precast concrete columns, which are heavy and hard to maneuver once set in place, the light-weight construction of the present column assembly  100  allows for easy placement and adjustability, particularly in view of any one of the height adjustment mechanism assemblies  130 ,  300 ,  400  described above. Concrete columns as well can be susceptible to cracking and water damage, which can again jeopardize the overall stability of a structure, and thus are not ideal for use as foundation supports. 
     Installation of the present height adjustable column assembly  100  in the construction of a post-frame building  500  is significantly easier than traditional foundation systems. Initially, a series of holes  600  are dug using known methods (for example, manually or using an auger) to create the intended perimeter of the building  500 . A separate height adjustable column assembly  100  is set, generally by hand by one or two persons, into each hole  600  ( FIG. 2 ). Each height adjustable column assembly  100  comes preassembled, and the pre-drilled holes  121  in various positions along the length of the arms  122  of the brackets  120 ,  128  make for simple attachment of grade boards, planks or splash boards set into the side support brackets  126  of the column assembly. The present column assembly  100  is much lighter than traditional wooden posts and concrete posts, making lifting and placing the column assemblies safer and easier, as well as, reducing or even eliminating the need for heavy machinery to assist in transportation and installation. In fact, each column assembly  100  can be adjusted by one or two persons without the requirement for heavy equipment and with precision while upright, which eliminates the need to correct wood post lengths on site. Additionally, another advantage of using the present adjustable column assembly  100  is that post hole depths do not need to be exact, and the standard height industry variation of +/−3 inches is done away with. After the appropriate height adjustment is complete using the particular height adjustment mechanism  130 ,  300 ,  400  described above, the excavated holes  600  can be filled with concrete to set the adjustable foundation column assemblies  100  in place to create the foundation. 
     As described, the adjustable column assembly  100  is used to create the foundation for a structure, by acting as a base for attaching grade boards and post frame columns. Although it is common to use wood grade boards for creating the foundation of a structure,  FIGS. 11-13  illustrate an alternative connection bracket and grade board combination device  700  that can be attached/used with any column  900 , which provides distinct advantages over use of traditional wood grade boards when building the foundation.  FIG. 11  shows the connection bracket  710 , which is designed to engage a grade board  800 , as shown in  FIG. 12 . The bracket  710  includes a center section  711 , an upper portion  712  and an opposing lower portion  714 . The upper portion  712  comprises a first section  712   a  angled outward from a top  711   a  of the center section  711  and a second vertical section  712   b  connected to the first section  712   a.  The opposing lower portion  714  comprises a first section  714   a  extending horizontally from a bottom  711   b  of the center section  711  and a second vertical section  714   b  connected to the first section  714   a.  The upper portion  712  and opposing lower portion  714  are designed to engage and support a grade board  800 , as shown in  FIG. 12 . 
     The grade board  800  itself is constructed from a galvanized steel, which is coated with a proprietary coating (InterCoat®ChemGuard by Chemcoaters, Gary, Ind.) to improve the corrosion resistance of the galvanized steel. It should be understood that although the grade board  800  is shown in a short length for illustration, the grade board can be provided in any standard or customized foundation board lengths. The grade board  800  includes a first section  810  connected through a middle second  812  to an opposing second section  814 , forming a substantially U-shaped configuration, which is complementary to the shape of the connection bracket  710  such that the grade board engages the bracket ( FIG. 12 ). The first section  810  and second section  814  each includes a center, longitundinal ridge  816 . Thus, the design of the center ridge  816  of the grade board  800  provides an option to stack and engage multiple grade boards one on top of the other, as shown in  FIG. 13 . Advantages of the connection bracket and grade board combination  700  include: configuration of connection bracket  710  permits easy, secure installation of the grade board  800 , without requiring special tools, while the coated, galvanized steel grade board is not subject to deterioration, rotting, cupping, warping, crowning or twisting, resulting in a true straight, long-lasting foundation for a structure. 
     The features and advantages offered by the present height adjustable column assembly  100  mean that installation of the foundation column is quick, yet precise. Each column assembly  100  can be accurately put in place quickly, with a typical installation of an entire foundation for a post-frame structure being completed in a single day. The speed and precision of installation makes the height adjustable column assembly  100  ideal for stub-ahead projects; crews can dig, set the columns and install the splashboard prior to concrete backfill. This is also beneficial to the new building owner because it allows subsurface work (plumbing, electrical, in-floor heat, etc.) to be complete and concrete flooring poured prior to the crew returning to build the building. 
     In short, the time savings in installation combined with the durability of foundations built using the present adjustable column assembly  100  translate directly into improved safety, costs and labor savings when compared to other traditional foundation methods. The lightweight nature of the present column assembly  100  means the columns can essentially be set in place by hand by one or two persons, reducing or eliminating the need for tools and heavy equipment, making job sites safer and resulting in more efficient crews. Since column heights and overall leveling can be easily adjusted on site, supporting structural wood columns can arrive pre-cut and ready for attachment to the foundation system. 
     Advantages of the present height adjustable column assembly  100  include that it is invulnerable to the rot, decay and insect damage that traditional wooden posts are susceptible to, nor will the present foundation column expand and contract due to freezing and thawing. The superior strength of the galvanized steel foundation column of the present assembly  100  means that the structural foundation will never twist or warp, allowing foundations that utilize the present device and system to be more durable and well-protected against destructive natural forces than the average post frame building foundation. 
     As an alternative to new construction of a building, oftentimes there is a need or desire to repair and reinforce existing post-frame structures, specifically the wood foundation columns found in many post-frame structures, barns and other buildings. Repair or reinforcement is preferred in terms of time and costs over complete replacement of wooden columns in many of these structures. Additionally, razing a structure may not be an option if the structure has historical or family value. 
     As shown in  FIGS. 14-17 , an embodiment of a reinforcement device in the form of a multi-sided sleeve  200 , is provided, which is useful for engagement with existing wooden columns  250  in post frame buildings. As illustrated in  FIGS. 14 and 15 , the reinforcement sleeve  200  includes an elongated body  210  comprising a longitudinal center section  212  integrally connected to a pair of opposing longitudinal legs  214  or side panels having a length equal to the center section. Each leg  214  includes multiple angles or bends  216 . It should be understood that the angles or bends can vary in number and degree, and are adjustable for accommodating columns or posts of varying sizes. The resulting structure is a three-side configuration with an opening  218  that enables the sleeve to be adjusted and wrapped around three sides (the face and two sides) of an existing column  250  or post having a variety of shapes and sizes. Optionally, as shown in  FIG. 15 b   , the sleeve  201  may include a slightly modified configuration, which is useful for corner or jamb columns. In this corner sleeve  201 , the side panels  202  include an outer lip  203  configured for meeting the walls of a structure at the corner of the structure. 
     The reinforcement sleeve  200  has an overall corrugated shape, including a plurality of curved bends  216 , folds or parallel and alternating ridges and grooves formed within the side panels  214  and the center section  212 . For example, and as shown in  FIG. 14 , in one embodiment, the center section  212  is includes a raised center  212   a.  Additionally, each side panel  214  includes a raised portion  214   a  in each panel. The raised center  212   a  and side panel raised portions  212   a,    214   a  provide the sleeve  200  with the adjustability to fit any shape of existing column  250 , and lends strength to the sleeve. It should be understood that the raised portions  212   a  and  214   a  of the center section and side panels, respectively, can have any shape of bend, curve, ridges or grooves, and thus the disclosure should not be limited to the embodiment shown. 
     As shown in  FIGS. 15 and 15   a , the reinforcement sleeve  200  further includes at least one uplift tab  222  positioned on one or both of the side panels  214 , The uplift tab  222  includes a plurality of teeth  224  ( FIG. 15 a   ). When the reinforcement sleeve  200  is placed over the existing wooden column  250 , and driven down around the column with a suitable manual tool (i.e., hammer or maul), jack hammer, hydraulic device or another other suitable means for driving the sleeve into the ground, the teeth  224  of the uplift tab  222  engage into the sides of the column  250  ( FIGS. 16 and 17 ). In this manner, the reinforcement sleeve  200  is secured around the wooden column  250 , and it cannot be removed. 
     The reinforcement sleeve  200  can be constructed from any suitable material, preferably steel, including galvanized steel for strength, longevity and corrosion-resistance. Additionally, the reinforcement sleeve  200  can have any length required for the particular project. For example, a sleeve  200  used for strengthening an existing column or post may be shorter in length than a sleeve that will be used for extending the height of a structure. Once installed into the ground  230  around an existing support column  250 , the reinforcement sleeve  200  can be secured to the existing support column, using any manner of fastener including nails, screws, bolts, etc., through fastener holes  220  on the sleeve. The reinforcement sleeve  200  acts to stiffen and reinforce the lower portion of the wooden column  250  against lateral, uplift, and downward pressures. Additionally, straps (not shown) may be used to further fasten the reinforcement sleeve  200  around the column  250  or post. 
     Installation of the reinforcement sleeve  200  may be completed with a specialty hydraulic driving device, similar to an automatic jack hammer, which mechanically drives the sleeve into the ground around the target column  250 . An advantage of using the hydraulic driver is that it reduces the amount of digging required to place the reinforcement device  200  into position. Although a slight amount of digging may be required around the base of the post or column to initially place the reinforcement device  200 , the driver secures the reinforcement device below grade using less time and manpower than traditionally required to place a second securing post. It should be understood that in place of the described driver, the reinforcement sleeve can also be installed using any suitable manual tool (i.e., hammer or maul), jack hammer, or another other suitable means for driving the sleeve into the ground. 
     Wood columns used to construct post frame buildings tend to fail over time due to dry rot and decay caused by microbial activity at the soil surface and just below the surface. This creates a risk of column failure or building damage, which is a real problem for the building owner, and can be very expensive to repair. The present disclosure also includes a system and method for reinforcing a column, post or other supporting structure for a building using the reinforcement device  200 . 
     The system and method for reinforcing and/or stabilizing a column  250  or post includes the steps of initially digging a shallow hole  230  or trench around the base of the target column  250 . The reinforcement sleeve  200  is then positioned within the hole  230  and over the existing column  250  from inside the building. Because of the corrugated shape of the reinforcement sleeve  200 , the center section  212  and legs or side panels  214  of the sleeve cradle and contact the column at multiple contact points as shown in  FIG. 14 . For example, as noted in the figure, the raised portions  212   a,    214   a  of each of the center section and legs do not directly contact the column  250 . The corrugated shape of the reinforcement sleeve  200  provides strength and spacing needed to drive the sleeve into position around the column. If the sleeve  200  fit tight against the column  250 , it would be harder to drive the sleeve down into position. 
     Although a reinforcement sleeve  200  is described as an option for reinforcing an existing wooden column, there is an option to use the height adjustable column assembly  100  described above in the repair of a structural column. Specifically, the existing column can be dug out of the ground and removed. The adjustable column assembly  100  would then be positioned in the ground, completely replacing the wooden column. Because the adjustable column assembly is not susceptible to the elements, or insect infestation, it would provide a long-term solution to maintaining the foundation of the existing building. 
     For decades, post frame buildings were built all across America that were designed to store equipment and machinery that was much smaller than what is in use on today&#39;s modern farms. As a result, many of these otherwise useful buildings are being removed to make room for new buildings with higher interior clearances. However, there is often a reason to save and restore existing buildings, including costs, historical value and sentimental value. 
     The present disclosure includes a system and method for raising the height of an existing structure by up to 36″, thereby increasing the useful interior space. The system and method for raising the height of a structure includes using the present reinforcement sleeve  200 . The reinforcement sleeve  200  can have any suitable length, for example up to 12 feet long, which makes the reinforcement sleeve useful for raising an older, shorter building to a newer height. Once the reinforcement sleeve  200  is installed around an existing column  250  as previously described, the existing wood columns can be extended up to 36″, thereby increasing the interior clearance and allowing the height needed for today&#39;s modern farm equipment, construction equipment, or just to provide additional interior storage space within an existing structure. 
     The method of raising an existing structure begins with cutting an existing column will both sides and on the face of the column. The reinforcement sleeve  200  will be driven into the ground (using some form of a driver as described above), leaving a suitable portion of the sleeve above grade. The remaining portion of the column  250  would then be cut separating the column into two pieces. The building or structure would be jacked up or lifted incrementally using known methods and equipment (i.e., jacks), until it reached the desired height. The gap from the lift would be filled with appropriate filler. A vertical fastener, such as a steel strap would be used to fasten and tie all the pieces together, including the sleeve  200 , which would also be attached to the column  250 . After raising the structure to the desired height, any void left under the existing sidewall would be filled in with appropriate material, for example, a new steel wainscot.
