ATTACHMENT 1 - -HAND HOLE And COVER.pdf

This document is a technical drawing detailing a precast concrete handhole design for a Federal Aviation Administration (FAA) project at Runway 26. The detailed engineering schematic provides comprehensive specifications for a 4'x4' aircraft-rated handhole with a spring-assisted lid, including precise measurements, construction requirements, and installation notes. Key technical specifications include:

Design requirements mandate the handhole be of uniform quality, free from blow holes, shrinkage, and distortion, and conform to Class 30 gray cast iron specifications. The handhole must be coated with a protective orange asphaltic-based paint and include specific reinforcing details such as ground rods, conduit sleeves, and fenrule inserts. The design includes detailed notes on concrete mixture, reinforcing bar specifications, joint sealing, and installation requirements, with explicit instructions for excavation, gravel bed preparation, and positioning of structural components. The drawing is part of a federal contract opportunity (Solicitation Number 697DCK-25-Q-00053) for manufacturing and delivering two precast handholes and four precast foundations for the FAA's Southwestern Region.
