PART 3 EXECUTION

3.01 EXAMINATION

A. Verify lines, levels, and dimensions before proceeding with work of this section.

3.02 PREPARATION

A. Formwork: Comply with requirements of ACI 301. Design and fabricate forms to support all applied loads until concrete is cured, and for easy removal without damage to concrete.

B. Clean forms and adjacent surfaces to receive concrete. Remove chips, wood, sawdust, dirt, and other debris just before placing concrete. Chamfer exterior corners and edges of permanently exposed concrete. Comply with Division 1 requirements for certified wood used for formwork and disposal of construction waste.

C. Verify that forms are clean and free of rust before applying release agent.

1. Where as-cast finishes are required do not use materials on the face of the form that will impart a stain to the concrete. Where the finished surface is required to be coated, the material applied to the form surfaces shall be compatible with the type of coating to be used.

D. Void Form System Placement: Store void forms and accessories in accordance with manufacturer's recommendations. Prepare ground surface on an even plane. There should be no capillary break below the void form unless otherwise directed by the designing engineer or architect. Assemble knockdown (K.D.) products as recommended by manufacturer to develop designed strengths. Install void forms and accessories in accordance with manufacturer's recommendations. Use end caps to seal exposed ends. Use seam pads to cover joints to prevent concrete intrusion. Place a layer of protective cover board over void forms as necessary to distribute working load, bridge small gaps, and protect them from puncture and other damage during concrete placement. Protect void forms from moisture, and replace wet or damaged pieces before placing concrete. Immediately protect exposed void forms after concrete formwork has been stripped with an HDPE retainer to keep backfill material from migrating into the voided area. The retainer should be installed per the manufacturer's recommendations. Maintain moisture and humidity levels beneath concrete structure.

E. Coordinate placement of embedded items with erection of concrete formwork and placement of form accessories.

F. Where new concrete is to be bonded to previously placed concrete, prepare existing surface by cleaning and applying bonding agent in according to bonding agent manufacturer's instructions.

1. Use epoxy bonding system for bonding to damp surfaces, for structural load-bearing applications, and where curing under humid conditions is required.

2. Use latex bonding agent only for non-load-bearing applications.

G. Interior Slabs: Install vapor retarder under interior slabs per ASTM E 1643 and the manufacturer's written instructions. Lap joints minimum 6 inches. Seal joints, seams and penetrations watertight with manufacturer's recommended products and follow manufacturer's written instructions. Use manufacturer's recommended pipe boot and tape to seal vapor retarder to all pipes, conduits, and other elements that penetrate slabs-on-grade. Repair damaged vapor retarder before covering per manufacturer's instructions. Where slab is poured over void forms, mechanically bond the vapor retarder to the undeside of the slab with textured tape per manufacturer's instructions.
