Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
					 General. When an application is filed, it shall be accompanied by one complete
					 set of the plans and specifications, the structural design computations, and a
					 fee calculated on the estimated cost. (See Section
					 20.)
The check prints of plans and specifications,
						computations and other data filed with the application are the property of and
						shall be retained by the office after the backcheck process is completed and
						until the project files are closed.
(b) Plans. Plans shall show the use or
					 occupancy of all parts of the school buildings and shall give such other
					 information as may be required to indicate the nature of the work proposed and
					 to show compliance with the act and these rules and regulations. The plans
					 shall be legible and sufficiently detailed and cross-referenced to show clearly
					 the pertinent features of the construction, and shall have sufficient
					 dimensions to be readily interpreted. Where a project includes several school
					 buildings, the plans for each shall be drawn independently except that details
					 common to all need not be repeated.
Submitted plans and specifications which are obviously
						incomplete or incorrect, shall be returned to the designer with a request for
						compliance with these rules and regulations before checking is resumed by the
						office.
(c) Specifications.
					 Specifications shall completely set forth the requirements for the various
					 types of materials that will enter into permanent construction and shall
					 describe the methods not covered in the technical regulations which are to be
					 used to obtain the required quality of the work shown on the plans as described
					 in the specifications.
(d) Design
					 Computations. Computations, stress diagrams and other pertinent data shall
					 accompany the plans and specifications and shall be sufficiently complete so
					 that calculations for individual structural members can be readily interpreted.
					 The computations shall be prefaced by a statement clearly and concisely
					 outlining the basis for the structural design and indicating the manner in
					 which the proposed school building will resist vertical loads and horizontal
					 forces. The computations shall be sufficiently complete to establish that the
					 structure will resist the loads and forces prescribed in Part 2, Title 24, CAC.
					 Assumed safe bearing pressures on soils and specified strengths of concrete
					 shall be given in computations and noted on plans. Where unusual conditions
					 occur, such additional data as are pertinent to the work shall be
					 submitted.
(e) Site Data. Site data
					 for all school sites shall include a soil investigation report including
					 sub-surface site work, laboratory testing, an evaluation of site soil
					 conditions, a recommendation for the type of foundations to be used and an
					 allowable design value for the soil bearing capacity.
For new school sites located in the "Special Studies
						Zones" (commonly known as Alquist-Priolo Zones) as described in Sections
						39002 and
						39002.5 of
						the Education Code, a geologic and earthquake hazard report including an
						evaluation of both known and potentially active local and regional fault
						systems and of slope stability and liquefaction potential as hazards to school
						structures, shall be submitted with the application.
For existing school sites, the Architect shall prepare a
						geologic hazards statement evaluating the potential for geologic or earthquake
						damage for projects involving alterations, additions or new
						construction.
(f) Estimates
					 of Cost. Estimates of cost shall be based on the cost prevailing at the time
					 the plans and specifications are submitted to the office. The estimated cost of
					 a project shall be increased as necessary to include the estimated cost of
					 every alternate building or portion thereof shown on the plans or
					 specifications as if each alternate building and portion were to be constructed
					 separately and simultaneously.
When a contract amount, or the cumulative total of two or
						more contract amounts, exceeds the estimated cost by more than 30 percent the
						estimated cost shall be revised. An additional fee based upon the revision
						shall be paid before proceeding with the work. When the actual cost of
						constructing all the work shown on the approved plans is less than 70 percent
						of the estimated cost a refund may be claimed. (See Section
						22 for actual cost.)
(g) Deferred Approvals. Where a
					 portion of the construction cannot be adequately detailed on the approved plans
					 because of variations in product design and manufacture, the approval of plans
					 for such portion may be deferred until the material suppliers are selected
					 provided the following conditions are met:
(1) The plans clearly indicate that a
					 deferred approval by the office is required for the indicated portions of the
					 work prior to fabrication and installation.
(2) The plans and specifications adequately
					 describe the performance and loading criteria for such work.
(3) The architect or structural engineer
					 responsible for preparation of plans and specifications for the project
					 manually signs the plans and specifications for the deferred approval items.
					 Such architect or structural engineer must prepare his own plans; however, he
					 may adopt or modify plans prepared by a manufacturer or anyone else provided
					 that he accepts responsibility thereof.
