The goal of this project is to clear vegetation from on top of the existing concrete slab and in the immediate area, while minimizing impact to the natural and built environment. A new slab would be poured over the existing concrete slab and a roof shelter would be installed over the new concrete slab. The contractor shall grub, trim, cut and dispose of all debris and material associated with the project. The contractor will clean the existing concrete slab and pour a new concrete slab over the existing slab. The contractor will install a gable roof. The bottom of the header is to be 8 feet from the finished concrete slab and the roof will have a 5 twelve pitch. The roof material is to be a standing seam, galvalume.

Install two, ABA compliant sidewalks from two sides of the concrete slab.

1. TASKS:

a) Clearing and Grubbing

b) Grub, trim and cut approximately 60 cubic yards of brush, small trees and limbs.

c) Dispose of approximately 20 cubic yards of concrete rubble.

Galvanized pipes are 2”x 12”, 1”x 6”, 3/4”x 18” and ½”x 6”.

3. Installation

a) Clean debris from existing slab and pressure wash entire 1300 square feet.

b) Place a layer of at least 4 MIL thick plastic sheeting over the existing, cleaned concrete slab.

c) Pour a 4” thick, 3000 psi, concrete slab over the existing concrete slab. The existing slab measures 30’x 40’. Slab is to have a fine, broom finish.

d) Place #4 steel rebar, in a 2’x 2’ grid, midway of the thickness of the new concrete slab and sidewalk.

e) Rebar is to be tied at each area where rebar crosses each, with at least 16-gauge, rebar wire.

f) Install two, ABA compliant sidewalks (one on the south side and one on the west side of the concrete slab. Each sidewalk is 5’ wide, approximately 30’ long and 4” thick.

g) Install an expansion joint at the points where each sidewalk meets the concrete slab and cut “Control” joints in both the slab and the sidewalk.
