B. Constructing an Overhead Form
1. Construct a concrete-overhead-beam form 1.1 Set the form bottom.
1.1.1 Make the width of the soffit out of 2-inch material, exactly like that of the member being formed, and its length equal to the distance
between the columns or the spans.
1.1.2 Cut the two ends of the form bottom at a 45-degree angle to produce a chamfer at the junction of the beam bottom and column.
1.2 Nail the chamfer strips with beveled ends to the beam-form bottom, flush with the outside edge.
NOTE: Chamfer strips are small pieces of wood (about 1 inch by 1 inch).
1.3 Cut the studs to the length called for in the specifications.
1.4 Cut and fasten the sheathing.
1.4.1 Use either 1-inch tongue and groove lumber or plywood.
1.4.2 Cut the sheathing should be cut to the length called for in the specifications and fasten it to the studs to create both side panels.
1.4.3 Nail sheathing sides so that they overlap the bottom piece of the form.
1.5 Cut and install the temporary spreaders.
1.5.1 Cut the temporary spreaders to the beam as stated in the specifications.
1.5.2 Install the temporary spreaders by using double-headed forming nails.
1.6 Install the shoring.
1.6.1 Use a large quantity of shoring to offset the downward hydrostatic pressure placed on the form bottom. Commercial adjustable-metal forms are available and are probably the best and easiest type of shoring to use on beam and girder forms (Figure 052-236-1165-2). Heavy timber such as 4- by 4-inch lumber is normally available and works fine.
1.6.2 Install shoring so that the beam form remains level.
Beam and Girder Form
C. Constructing a Concrete-Slab Form 1. Construct a wooden-form slab
1.1 Construct the formwork. Measure and mark the side-form material to the required lengths.
1.1.1 Make two pieces the actual length of the slab and two pieces length of the slab plus two times the thickness of the material.
1.1.2 Nail the form sides together at the corners.
1.2 Place and secure the formwork.
1.2.1 Place the formwork at the specified location.
1.2.2 Square the forms by using the diagonal method.
1.2.3 Drive the stakes at all the corners and
approximately 3 feet along the entire perimeter of the form.
1.2.4 Level the
formwork, then nail the forms to the stakes.
1.3 Cut and place
polyethylene plastic in the bottom of the form as a vapor barrier.

• Circular Saw Steps/Procedure:
1. Prepare the necessary tools, equipment and materials to be used.
2. From the given working drawing, stake-out building lines and batter boards (refer to Job Sheet No. 1.2-1 on staking out building lines)
3. Fabricate the column-form sides (refer to Operation Sheet No. 2.2-4 and 2.3-2 regarding the fabrication of formworks)
4. Erect scaffolding. Observe safety in installing scaffoldings.
5. Install column-form panels reinforcement.
6. Fasten the column sides. After the four sides of the column form have been constructed, fasten them together and set them in place. Check the plumbness, levelness and squareness using appropriate tools.
7. Install column-form reinforcement 8. Install ties.
9. Provide bracing for column-form sides 10. Place secondary and main reinforcement
