- 451 - SECTION 701 -- GENERAL REQUIREMENTS
701.01 Description
1.This Section describes proc edures and equipment that are common to a variety of structures as described in Division 700.
701.02 General Procedures
1.The Contractor shall excavate and place shoring as necessary to insure safe access to work areas.
2.Concrete Proportioning: a. Concrete shall be proportioned, mixed and delivered under inspection of the Engineer.
b.A copy of the concrete load tickets shall accompany each load to the placement site and be availabl e to the Engineer. Acceptance of the concrete at the placement site will be partially based upon verification that the concrete is of the proper class and has been delivered within the specified time limits.
c.Loads which are not accompanied by such tickets, which do not arrive in satisfactory condition, or which do not arrive within the specified time limits shall be rejected.
3.When unsuitable material is encountered, it shall be removed. Excavation will continue until the unsui table material is removed or until the Engineer halts excavation.
4.When a concrete bottom seal course is required due to unforeseen conditions, the excavation shall be su fficient to allow for placement of the seal under the structure.
5.The Contractor shall not excavate within 5 feet (1.5 m) of any cast- in-place concrete deadman or grade beam tie rod anchor except for the limits of tie rod trenches and granul ar backfill as shown in the granular backfill details.
6.Concrete Placement and Consolidation:
a.Concrete shall be placed and consolidated in its final position with the utmost care.
b.The method used to place concrete shall not allow the concrete materials to segregate or displace reinforcing steel.
c.The impact of any free fall s hall be kept to the lowest levels consistent with efficient placement.
d.The maximum free fall plac ement distance shall be 5 feet (1.5 m).
e.The use of vibrators to mo ve concrete shall be prohibited.
7.The Contractor shall backfill bridge abutments, wingwalls, and retaining walls concurrently on all sides.
8.Cofferdams: a. Cofferdams shall be substantially watertight. The interior dimensions of cofferdams shall be such as to give sufficient clearance for the construction and inspection of forms.
