LANL MASTER SPECIFICATION

This template must be edited for each project.  In doing so, specifier
must add job-specific requirements.  Brackets are used in the text to
indicate designer choices or locations where text must be supplied by
the designer.  Once the choice is made or text supplied, remove the
brackets.  The specifications must also be edited to delete
specification requirements for processes, items, or designs that are not
included in the project \-- and specifier's notes such as these.  To
seek a variance from requirements in the specifications that are
applicable, contact the Engineering Standards Manual Civil
[POC](http://engstandards.lanl.gov/engrman/3civ/htmls/civilnew2.htm).
Please contact POC with suggestions for improvement as well.\
\
When assembling a specification package, include applicable
specifications from all Divisions, especially Division 1, General
requirements.\
\
Specification developed for ML-4 projects.  For ML-1, 2, and 3
applications, additional requirements and independent reviews should be
added if increased confidence in procurement or execution is desired;
see ESM Chapter 1 Section Z10 Specifications and Quality sections.

    grading as noted on Drawings.

G.  Allow footing to cure minimum 7 days before installing fabric and
    other materials.

## GATES

A.  Provide non-lift-off type gate hinges sized for gate of adequate
    strength with large rearing surface for clamping in position so that
    hinges do not easily twist or turn with gate action.

```{=html}
<!-- -->
```
H.  Provide diagonal tension rods for gates over 6 feet in width.

I.  For gate leaves greater than 8 feet in any direction, provide
    intermediate braces placed symmetrically so that frame members,
    including bracing, are spaced not further than 8 feet. Provide
    braces same size as those called out for fence.

## LATCHES

A.  Single gates less than 10 feet wide may use forked type latches.

```{=html}
<!-- -->
```
J.  Provide single gates, 10 feet, or more, wide, and inactive leaves of
    double gates with positive latching devices at top, bottom and
    center of closing edges such as fork type latches with full gate
    height plunger bar or rod.

K.  At double gates, provide locking devices that retain both gate
    leaves in same plane when closed.

L.  Arrange plunger bars and rods so that they engage gate stops and
    cannot be raised when locked.

M.  Rigidly weld brackets for plunger bars holders to inactivate leaves.

N.  Arrange latching mechanisms at double gates so one padlock can lock
    both gate leaves at center latch integral to gate.

O.  Install keepers consisting of a mechanical device for securing free
    end of gate when in full open position.

## PostS 

A.  Space line posts equidistant at intervals not exceeding 10 feet.
    Measure interval parallel to grade of proposed fence and in line of
    fence from center to center of post.

```{=html}
<!-- -->
```
P.  Set terminal posts (end, corner, and gate) at beginning and end of
    each continuous length of fence and at abrupt changes in vertical
    and horizontal alignments.

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

    increase in fence height over 4 feet.

```{=html}
<!-- -->
```
R.  Set posts in a vertical position, plumb and in line. Backfill
    concrete into excavation and extend 2 inches above grade. An
    alternative method is to stop footing 2 inches below grade to allow
    for cover with sod, black top, or other materials. Crown concrete at
    top to shed water and extend minimum of 2 inches below bottom of
    post.

S.  When solid rock or concrete is encountered, without an overburden of
    soil, set posts in solid rock or concrete. Depth of hole shall be
    twelve times the largest cross section of posts. Diameter of hole
    shall be 6 inch greater than largest cross section of post.

T.  The use of sleeves in order to leave voids in new concrete
    construction is recommended.

U.  Half-fill the void with non-shrinkable hydraulic cement and force
    post to bottom of hole and plumb. Thoroughly work additional grout
    into hole so as to leave no voids. Crown grout to shed water.

V.  Provide tension offset bands fitted around terminal posts at maximum
    15 inch intervals to attach tension bars to posts.

W.  Provide brace center band to secure brace ends and tension rods to
    post.

## FABRIC

    bracing, and other structural members on inside of secured
    perimeter.

```{=html}
<!-- -->
```
X.  Place fabric by securing one end, applying sufficient tension to
    remove slack before making attachment elsewhere. Tighten fabric to
    provide smooth uniform appearance free from sag.

Y.  Cut fabric by untwisting a picket and attach each span independently
    at terminal posts. Use stretcher bars with tension bands at maximum
    15-inch intervals or any other approved method of attachment.

Z.  Install fence fabric 2 inches maximum above ground level. Fasten
    fabric to line posts at intervals not exceeding 15 inches. Fasten
    fabric to rail or tension wire at intervals not exceeding 24 inches.

A.  Join rolls of wire fabric by weaving a single picket into ends of
    rolls to form continuous mesh.

B.  Provide continuous length tension bars equal to fence height and
    located wherever chain link fabric end attaches to terminal post.
    Thread bars through fabric ends for full height, and attach to posts
    by tension bands.

C.  Provide wire ties for attaching chain link fabric to tension wires
    at maximum 18 inch centers and fence posts at maximum 24 inch
    centers.
