HW#2 – RSMeans Estimating

Prof. Ralph V. Locurcio, PE

HW#2 USING RS MEANS

Prob #1- Forms

Prob #1:

Calculate the price to construct 100lf of forms in place for concrete footings.

Footings are 4ft deep; two sides; use continuous plywood, 4 use. Use SFCA (square foot of contact area) for calculations.

Do not include concrete or rebar. Show the price for materials & labor in separate columns and a total cost for the wall, including 10% overhead & profit (combined).

Prob #1 Solution

Prob #1

03 11 13.45-0150

Forms in place,

footings, continuous

wall, plywood, 4 use

Two forms are required Walls are 4ft deep x 100lf long = 400 SFCA per form 2 Forms required

                               

   

SFCA = 4' x 150' x 2 ea = 800SFCA

Prob #2 – Bond Beam

Prob #2:

Calculate the price to construct 100lf of concrete block, bond beam.

Use lightweight block, 6” thick

Do not include concrete or rebar. Show the price for materials & labor in separate columns and a total cost for the wall, including 10% overhead & profit (combined).

Prob #2 Solution

Prob #2

04 22 10.16-0525

Concrete block bond beam, not including grout or

reinforcing, lightweight, 6"

thick

Bond beam is only the top course in the wall so you only need 1 row of blocks, pricing is per LF

                               

   

One row of blocks is required; 100lf long
