Insulated Concrete Forms (ICFs) (cont.) Expanded polystyrene (EPS) forms for residential and commercial reinforced concrete walls 4", 6" or 8" thick. Based on standard sized block connected with plastic clips and reinforced with steel bars before cores are filled with concrete. Costs assume forms are left in place as wall insulation and that no concrete finishing is required. See www.eco-block.com. The crew is a carpenter and a laborer. Material costs include EPS forms and connectors as described but no concrete or rebar.
  Corner blocks, each includes 8 panel connectors

    24" 45 degree panel connectors, per box of 40 — Ea 166.00 — 166.00
Material and labor for EPS forms. These figures assume footings or concrete slab are in place and ready to accept the first course of forms. Material includes forms, connectors, rebar and concrete for a 6" wall. Labor includes erecting forms, setting rebar and pouring concrete in walls to 8' high. Assume that each square foot of wall requires 1 linear foot of #4 rebar.
    Per square foot of wall, below grade B1@.060 SF 5.36 2.00 7.36
    Per standard block (5.3 SF), below grade B1@.318 Ea 28.50 10.60 39.10
    Per square foot of wall, above grade B1@.080 SF 5.36 2.66 8.02
    Per standard block (5.3 SF), above grade B1@.424 Ea 28.50 14.10 42.60
      Add for 8" walls — % 12.0 5.0 —
      Deduct for 4" walls — % -8.0 -5.0 —
Cement and expanded polystyrene forms Similar to EPS forms above but with cement added to the mix: Recycled polystyrene (85%) and concrete (15%) building blocks with a grid of internal chambers designed to be placed either horizontally or vertically. Available brands are Rastra Block and Grid-WALL. Once the panels are in place they are filled with concrete providing a high strength, fireproof structural grid. Includes cement filling and grouting. When cut for odd sizes use per sq ft pricing.
Material unit costs for Grid-WALL systems
  Standard wall block, 5.3 SF per block
    48" L, 16" H, — Ea 28.80 — 28.80
Labor and material for wall construction
Material includes cost of Grid-WALL but not concrete or rebar. Labor includes stacking, leveling, adding rebar, bracing and prepping the wall but not the concrete pour.
    Per square foot of wall B1@.058 SF 5.45 1.93 7.38
    Per standard block (5.3 SF) B1@.313 Ea 28.80 10.40 39.20
    Add to labor if concrete pour included — % — 20.0 —
Use to calculate concrete and rebar costs:
1.1 cubic yards of concrete are required to fill 100 square feet of Grid-WALL.
1 Grid-WALL block will take 8 ft. of rebar, unless engineered otherwise.

The figures above are from a time and money saving construction cost manuals from Craftsman Book Company. Over 50 cost estimating databases are available and all come with the popular National Estimator program.
