Residential line panels from either of the two manufacturers are not acceptable!

Q. Label the new panel with the new circuit descriptions in typewritten print for the panel legend/directory.

R. All wires shall be copper, installed in conduit with type XHHW or RHW-USE) insulation.

S. The Contractor will install a nine inch rebar grid of 1/2” rebar for the reinstallion of the sidewalk section that was removed. The rebar grid will be tied together with tie steel at each crossover/contact point. Each piece of the rebar that spans between the existing sidewalk in the grid will be pinned into both sides to the existing side walk. The rebar will be pinned 1 ½” into the adjacent side walk slabs with the addition of adhesive into the drilled holes of the adjoining sections of the concrete side walk. See drawings.

T. The rebar grid will be supported off the base of the hole prior to the installation of the concrete by block or rebar saddles as necessary. The Contractor will not hook and pull grid into place during the concrete pour.

U. The new section of side walk will be poured with 3000psi or greater concrete. The concrete sidewalk will be poured flush with the adjacent sidewalk sections and will have rounded edges around the top on all sides with the use of a standard concrete edging tool.
