|Beam and girder forms Using nails, snap ties and oil, 1.3 SF of 3/4" plyform and 2.1 BF of lumber per SFCA. For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and erect 250 to 300 SF of beam and girder forms in an 8-hour day. For more detailed coverage of beam and girder forms, see National Concrete & Masonry Estimator, http://CraftsmanSiteLicense.com|
|Shores for beams and girders Using 4" x 4" wooden posts. These figures assume an average shore height of 12'0" with a 2'0" long horizontal 4" x 4" head and 2" x 6" diagonal brace (30 BF of lumber per shore) and include nails, adjustable post clamps and accessories. For scheduling purposes estimate that a crew of 5 can lay out, fabricate and install 30 to 35 adjustable wood shores in an 8-hour day when shores have an average height of 12'0". Quantity and spacing of shores is dictated by the size of the beams and girders. Generally, allow one shore for each 6 LF of beam or girder. Costs for heavy-duty shoring are listed under General Requirements, Heavy-Duty Shoring.|
|Elevated slab forms These are costs for forms per square foot of finished slab area and include shoring and stripping at heights to 12'. Bays are assumed to be 20' x 20' bays.|
|Waffle slab-joist pans, monolithic Using rented forms (30-day rental period minimum). For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and install 500 to 600 SF of waffle slab-joist pan forms and shoring in an 8-hour day. Two uses of the forms in a 30-day period is usually the maximum.|
|Metal pans, 10,000 to 20,000 SF [view picture]|
|Fiberglass pans, 10,000 to 20,000 SF|
|Flat slab with beams, monolithic Including nails, braces, stiffeners and oil 1.2 SF of plyform and 3.2 BF of lumber per SFCA for one-way beam systems. Two-way beam systems require approximately 40% more forming materials than one-way beam systems. For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and erect 350 to 400 SF of one-way beam systems and 250 to 300 SF of two-way beam systems in an 8-hour day, including shoring.|
|One-way beam 1 use||F5@.110||SFCA||3.71||5.21||8.92|
|One-way beam 2 uses||F5@.080||SFCA||2.83||3.79||6.62|
|Two-way beam 1 use||F5@.152||SFCA||5.09||7.20||12.29|
|Two-way beam 2 uses||F5@.100||SFCA||2.98||4.74||7.72|
|Structural flat-slab Using nails, braces, stiffeners and oil costing $.25, 1.2 SF of plyform and 2.25 BF of lumber per SFCA. For scheduling purposes, estimate that a crew of 5 can lay out, fabricate and erect 500 to 600 SFCA of structural flat-slab forms in an 8-hour day, including shoring.|
|Slab forms 1 use||F5@.069||SFCA||3.13||3.27||6.40|
|Slab forms 3 uses||F5@.048||SFCA||1.69||2.27||3.96|
|Slab forms 5 uses||F5@.043||SFCA||1.40||2.04||3.44|
|Additional forming costs for elevated slabs, if required Based on single use of plyform and lumber. For scheduling purposes estimate that a 5 man crew can install 500 SFCA per 8-hour day.|
|Curbs and pads||F5@.083||SFCA||3.13||3.93||7.06|
