EXECUTION

BATCHING AND MIXING

The Contractor shall have available at all times sufficient approved materials such that, when once started, concreting shall be a continuous operation until the placing of the panel or section is completed. The top surface shall be generally level.

When construction joints become necessary, they shall be made as hereinafter specified.

All concrete shall be mixed not less than 60 revolutions in the drum of a modern power mixer, at the rated speed of rotation. Mix not less than an additional 30 revolutions after the addition of any further water to the mix.

Transit-mixed concrete shall be transported to the job site unmixed and only after arrival at the job site shall mixing begin. All concrete shall be unloaded from the mixer within 45 minutes after completion of mixing. All concrete still remaining in the truck shall be rejected.

The total time interval from the time the cement makes contact with the aggregate to the complete unloading from the mixer shall not exceed 90 minutes, unless such time is extended by the Engineer. The time may be reduced in hot weather or under unusual conditions, if unsatisfactory results are obtained.

FORMWORK

The Contractor shall design and construct suitable and adequate formwork in conformance with ACI 347R.

All shoring shall be properly braced to safely withstand all vertical, moving and lateral forces during the construction period.

Section 03 30 00 Cast-In-Place Concrete

Set forms true to line and grade and make mortar-tight.

Chamfer above grade exposed joints, edges, and external corners of concrete 3/4-inch, unless otherwise indicated.

Before concrete placement, coat the contact surfaces of forms with a non-staining form coating compound.

Do not use mineral oil on formed surfaces to be painted. Prevent concrete damage during form removal.

Concrete for footings may be placed in excavations without forms upon inspection and approval by the Engineer.

Excavation width shall be a minimum of 4 inches greater than finished dimensions indicated.

It shall be the Contractor’s responsibility to determine the time at which forms may be removed without endangering the structure, subject to the following limitations, unless documentation is provided to modify these requirements:

Footing forms: 24 hours minimum; continue curing as specified.

Wall forms: 2 days minimum for ten (10) feet high. Add one (1) day for each additional five (5) feet of height; continue curing as specified.
