2.2.6.5 Vapor Barrier: The Contractor shall place a minimum of 5-mil vapor barrier under the slab on grade. Visqueen or plastic sheeting are acceptable vapor barriers.

2.2.6.6 Placement Restrictions: Concrete shall not be placed when the air temperature is below 7°C (45°F) and falling. Concrete may be placed when the air temperature in the shade is 4°C (40°F) and rising. Concrete exceeding 40°C (100°F) shall be rejected.

2.2.6.7 Transit Time: The maximum allowable time between the initial introduction of water into the mix and depositing the concrete in place shall be 60 minutes, unless a water reducing and retarding admixture has been added to the mix, then the maximum allowable elapsed time shall be 90 minutes. If the above time intervals are exceeded, the Contractor shall cut back the previously placed fresh concrete to a point of full depth concrete and install a doweled construction joint.

2.2.6.8 Protection From Weather: Have available at the site, at all times when concrete placement operations are underway, materials for protection of the surface of the concrete. When rain appears imminent, stop all paving operations and have all available personnel cover the surface of the unhardened concrete with the protective covering.

2.2.6.9 Delivery Certification: A delivery ticket shall be furnished with each batch of concrete delivered to the job site. At a minimum, the delivery ticket shall include the quantities of materials incorporated into the batch and the time of initial introduction of water to the mix. The delivery ticket will be signed and dated by the plant manager or his designee. Upon arrival at the project site, the superintendent or foreman shall record the arrival time, and the time at which the concrete is completely discharged from the truck and sign the delivery ticket. The delivery tickets shall be provided to the Contracting Officer or Project Engineer at the earliest opportunity.

2.2.6.10 Placement: Immediately prior to concrete placement, the forms and base material shall be thoroughly dampened. Concrete shall be distributed on the aggregate base course to such depth that, when consolidated and finished, the slab thickness required by the plans will be obtained at all points and the surface will at no point be below the grade specified for the finished surface, within a tolerance of 2 cm (0.79 in). Deposit the concrete in a manner that will require as little re-handling as possible. Any necessary hand spreading shall be done with shovels or other tools designed for distributing concrete, not rakes. Ensure that workers do not walk in the freshly deposited concrete with earth or other deleterious substances on their boots or shoes.

2.2.6.11 Consolidation: Each layer of concrete shall be consolidated by internal vibrating equipment.

Internal vibration shall be systematically accomplished by inserting the vibrator through the fresh concrete in the layer below at a uniform spacing over the entire area of placement.

2.2.6.12 Broom Finish: A broom finish shall be applied to the concrete pad. This shall be done as soon as the surface will support the broom to provide an even, uniformed non-skid surface finish without removing surface paste and fines. Finished surfaces shall be protected from damage during the construction period.

2.2.6.13 Curing: Begin curing immediately after placement and continue for at least 7 days. All concrete shall be cured and protected from premature drying and extremes in temperature. All concrete shall be completely covered with plastic sheeting that is weighted down to ensure it does not blow away in 48.2 km/hr. (26 knots, 30 mph) winds as soon as the concrete is stable enough to hold the plastic but no greater than 3 hours. The weights shall not be placed on the wet concrete.

Burlap mats shall accomplish moisture for concrete surfaces not in contact with forms. Under this method, cover the surfaces to be cured with burlap mats. Thoroughly saturate the mats with water before placing them. Use mats of such dimensions that as laid they extend to at least 5 cm (2 inches) beyond the edges of the strip of concrete placed. Place and weigh down the mats to cause them to remain in intimate contact with the surface being cured throughout the curing period. Maintain the mats fully moist and in position for the entire curing period. Curing shall continue for a period of seven days.

2.2.6.14 Removal of Forms: Do not remove forms from freshly placed concrete until it has set for at least 12 hours. Remove forms carefully to avoid damage to the slab. The Contractor will be responsible for replacing any damaged concrete.

2.2.6.15 Finishing Formed Surfaces: The Contractor will ensure all fins and loose materials are removed, and all surface defects greater than 5 mm (0.2 in) are filled. All honeycomb areas and other defects shall be repaired. All unsound concrete shall be removed and repaired. All concrete edges, joints, and surfaces will be neat, clean, and aesthetically pleasant (based on a standard articulated by the COR). Portions of concrete or joints that are not aesthetically pleasant will be removed and redone by the Contractor.

2.2.6.16 Joints: The Contractor shall install construction joints and contraction joints.

2.2.6.16.1 Steel Dowels: The Contractor shall install dowels along construction joints as specified in the design approved by a licensed professional engineer. All dowels will be straight, smooth, and free from burrs at the ends. One end of the dowel will be painted and oiled to prevent bonding with the concrete. The opposite end will be secured into existing concrete with epoxy prior to pouring the new concrete.

2.2.6.16.2 Expansion Board: The Contractor shall install expansion board for expansion joints at all cold joint locations as specified in the design approved by a licensed professional engineer.

2.2.6.16.3 Longitudinal Construction Joints: No slab may be more than 6m in width, construct longitudinal construction joints in order to achieve this requirement where concrete construction is more than 6m. Where keyways are required, the Contractor may form them by placing an insert of the proper shape along the inside face of the side form.
