Method Statement for Installation of Fencing

What is Fencing?

Fencing in the context of construction refers to the process of building fences or barriers for security, privacy, safety, or boundary marking purposes.

Installation of Fencing

This method statement for installation of fencing outlines the procedure and methodology for the work involved in the erection and installation of boundary fencing within the scope of the contract.

Methodology

Fencing Installation

All staff accessing the site must have received site safety training and a job toolbox discussion.

The Fencing Site Engineer will issue a Permit to Dig and advise those carrying out the works on basic health and safety problems as well as the dangers linked with excavation services.

Sequence of Construction

A Setting Out Engineer or Surveyor will set out the fence lines. Pegs (labeled PFL) will be installed at all changes in direction of the fence line, as well as at appropriate centers for arcs in the fence line. Also set forth will be the locations of the gates.

Prior to accessing areas, the Section Foreman shall consult with pertinent landowners on the livestock protection system that has been implemented. Prior to the start of fencing works, the Section Engineer will issue a Permit to Dig (PTD) to the foreman of the fencing crew.

Timber post and rail fences shall be erected using a tractor/excavator mounted hydraulic post driver where ground conditions permit. This post driver must be equipped with a particular cap to fit and protect the top of the post.

Temporary posts must be set up with a line wire at the bottom rail level to ensure horizontal and vertical alignment.

The posts’ locations will be decided by placing rails on the ground along the intended fence line. At the ends of the rails, posts must be driven or fixed.

Rails must be overlapped by approximately 50mm every fourth rail to accommodate curvature in both the horizontal and vertical alignment. This will prevent rails from not meeting in the center of the posts.

Rails will be fixed after the erection of permanent posts. Rails must be treated with two coats of preservative where they must be cut. By nailing or nail gun, timber rails must be fixed to posts. When end splitting of rails occurs, the affected rail sections must be replaced, and rails must be pre-drilled.

If the post refuses to enter the ground to the required depth after utilizing the hydraulic post driver, the technique of erection is to excavate and backfill the posthole. The hydraulic post driving posts would also be utilized for the “excavate and backfill” procedure.

Posts embedded in rock must have holes drilled to a depth of at least 700mm and the post hole backfilled with concrete once the post is installed.

During the fencing process, or by a different crew following behind, chain link mesh will be fixed to the rails.

A 300mm wide by 200mm deep trench will be constructed along the fence line on the other side of the fence posts. This will occur when the posts and rails have been erected.

The fence mesh will be positioned horizontally across the bottom of the 300mm trench and up the fence. The mesh will be secured up to the height of each neighboring post and the trench will be backfilled over it.

Gates will be provided in accordance with the contract designs’ specifications. These must be suitably supported at the far end until the concrete around the posts has set.

The site’s access points must be approved. All works will be carried out within the permanent fencing perimeter.

Potential consequences (in the absence of the below mitigation):

Surface and groundwater contamination could occur during construction.

During construction, there may be an increase in run-off flows to Turlough.

Surface water run-off pollution during construction.

Direct habitat/flora species loss during construction.

Mitigation

An environmentalist with the necessary qualifications will oversee construction works near the working area.

The period of exposure of bare sections and uncontrolled runoff from new hard-standing areas will be minimized to reduce potential increases in flows into the drainage system and downstream during construction. The early covering, seeding, and planting of exposed surfaces will be undertaken.

Material stockpiles will be kept to a minimum, covered, and located at least 10m away from the drainage system and 100m away from the site.

A variety of temporary measures will be implemented to prevent contaminated or silt-laden runoff from entering the area, including silt barriers, cut-off ditches, silt traps, straw bales, entrapment matting, and drainage to vegetated areas.

Runoff will be controlled and, when required, diverted to settling ponds or sumps. Any interim treatment and attenuation facilities will be planned and implemented in line with CIRIA C697 (2007). All temporary treatment systems will be inspected and maintained on a regular basis.

To prevent vegetation removal and soil exposure and/or compaction, the amount of construction operations shall be controlled. To prevent unintended encroachment from construction equipment, the land surrounding the immediate construction area will be fenced off or otherwise designated.

Construction works will not be done during lengthy periods of very severe rainfall.

No construction equipment or vehicles are permitted to enter the area boundary except where it has already been generally encroached by the existing road.

Refueling of machinery must be done off-site or within 100m of area habitat if done on-site.

All fuels, oils, greases, hydraulic fluids, and chemicals will be stored in bunded compounds/areas on impermeable bases at least 10m from the planned drainage system and 100m from the site area.

During construction, turbidity (suspended solids) monitoring will also be undertaken on a weekly basis. If suspended solids concentrations exceed the 95th percentile of those monitored during the pre-construction monitoring period, the Sediment and Erosion Control methods and plan will be reviewed, and further sediment control measures will be implemented as required.
