1.5.2 Risk Management

A risk management assessment tool, such as activity hazard analysis (AHA), job safety analysis (JSA), or job hazard analysis (JHA) shall be developed by the contractor performing the work for each activity, task, or defined feature of work (DFOW). The assessment shall identify the work sequence, specific anticipated hazards, site conditions, equipment, materials, personnel, and the control measures to be implemented to control the hazards. If Qualified or Competent Persons are required for a particular activity, they shall be identified and included in the assessment, and their competency/qualification identified. Work shall not begin until the assessment has been accepted by the Contracting Officer and discussed with all engaged in the activity.

These risk assessment tools are considered living documents and shall be updated as needed. If the RAC increases from what was originally accepted by the Contracting Officer, the assessment shall be re-submitted for acceptance prior to work proceeding.

Changes that do not increase the RAC are not required to be resubmitted for acceptance. The risk assessment shall be developed in accordance with EM 385-1-1 Section 1, or as specified by the Contracting Officer.

Contractor shall submit manufacturer’s information that substantiates the proposed materials or systems are products of standard manufacture and are suitable for their intended use. All parts and materials shall be compatible and shown to provide the same level of performance as that specified.

3 EXECUTION

3.1 VEGETATION CLEARING

A path of between 6 to 8 feet in width has been cleared along the alignment of the fence, and consisted of the hand removal of shrubs and small trees. The contractor shall be responsible for removal of any vegetation that has regrown and interferes with the contractor’s operations. Grubbing will not be required. Large trees that cannot be avoided by slight changes in the fence alignment shall be the contractor’s responsibility to cut and lay aside. Removal and disposal of vegetation or trees will not be required, and such material shall be allowed to remain on site away from the fence alignment.

3.2 SPILLWAY SAFETY FENCING

The fence shall be installed at the approximate alignment indicated on the contract drawings. The ACO or designated representative and the Contractor shall mutually inspect the alignment location and agree on any changes to the final alignment. The alignment may be modified to accommodate unforeseen abrupt changes in terrain or obstacles, but shall minimize the need for bracing. All excess fence material at the completion of the work shall be removed from the work site.

3.2.1 Post Placement

Post placement shall be a maximum of 20 feet on centers. Spacing shall be adjusted for abrupt changes in terrain that make it impossible to maintain proper clearance between ground level and bottom of fence. Bracing shall be required at all corners, ends and gates in the fence. Posts shall be set at a minimum depth of 36 inches.

3.2.1.1 Corner Brace Assemblies

Corner brace assemblies shall be required at all points where the changes 15 degrees or more. Three vertical posts and two horizontal braces are required for each corner (two H-Braces).

3.2.1.2 End Brace Assemblies

3.2.1.3 Post Installation

Posts may be driven by use of a mechanical post driver without damaging the posts to a minimum depth of 36 inches, or the posts may be set by auguring a 12” diameter hole a minimum depth of 36 inches depth, setting the post with backfill material, and firmly hand tamping. All posts shall be set plumb and in straight lines.

3.2.2 Wire Fabric Installation

Woven wire fabric shall be installed to provide a maximum of 6 inches above ground level or as directed by the Contracting Officer to accommodate terrain conditions. To maintain this clearance, existing on site soil may need to be placed below the fabric or post spacing may need to be adjusted to suit terrain. After the wire fabric is permanently tied off at one end of a braced assembly, the fabric can be stretched, spliced, and permanently stapled to the line posts. Staples shall be installed on the line posts loose enough to allow the woven wire to slide to allow for expansion and contraction.

3.2.3 Gate Installation

Gates shall be installed at the approximate locations shown at a corner post to minimize the need for additional bracing as directed by the Contracting Officer.
