Area 43/270 Perimeter Wall and Gate Replacement

The project involves the complete demolition and reconstruction of the perimeter boundary wall at Area 43/270, accompanied by a full suite of site improvements. Initial work includes installing a temporary iron-sheet fence with razor wire for security, followed by the removal of the existing wall, clearing of trees and roots, and debris disposal. Construction proceeds with excavation to a depth of 900mm, concrete blinding, and the installation of reinforced strip footings, columns, mid-height and top beams, and 200mm hollow blockwork with both vertical and horizontal reinforcement. The finished walls will be plastered, roughcast, treated with silicone primer, and coated with weatherproof paint, while foundation walls receive a bituminous waterproofing layer. A new 3.50m by 2.75m sliding vehicle gate with an integrated pedestrian door, heavy-duty hardware, peep hole, and concertina wire will be fabricated to ASTM standards, with razor wire extended along the entire perimeter. Additional scope encompasses perimeter drainage using brick-lined channels, catch pits, and uPVC piping, repairs to the guard house including roof, door relocation, electrical upgrades, and drainage, restoration of the screen wall, and installation of security lighting at the gate area. The project concludes with comprehensive site cleanup, landscape restoration, utility repairs, and repainting of any disturbed surfaces. All work must strictly adhere to material specifications, testing protocols, and safety standards including EM 385-1-1, BS, and ASTM codes, with COR oversight ensuring compliance on compaction, concrete quality, and reinforcement placement.
