F-20

Place the reinforcing steel cage as a unit immediately after the drilled hole is inspected, accepted, and before concrete placement. Remove cage when directed by the CO for re-inspection if concrete is not placed immediately. Handle reinforcing cages in a manner to avoid distortion or racking of the steel.

Provide positive support at the top for the reinforcing steel cage during concrete placement.

Maintain the top of the reinforcing steel cage no more than 6 inches (150 millimeters) above and no more than 3 inches (75 millimeters) below the required elevation. Make acceptable corrections if the reinforcing steel cage is not maintained within tolerances. Do not construct additional shafts until the method of reinforcing steel cage support has been approved.

565.08 Concrete for Drilled Shafts. Delete the fourth paragraph and substitute the following:

Furnish concrete conforming to Section 552, except:

(a) Class A (Drilled Shafts) structural concrete having a slump of 71 inches (18025 millimeters) for shafts constructed without drilling fluid;

(c) Class S concrete for under water placement.

565.09 Integrity Testing. Delete this Subsection.

565.10 Acceptance. Amend as follows:

Delete the text of Subsection (b) and substitute the following:

Remove and replace rejected shafts or propose alternatives according to Subsection 106.01.

Submit design modifications to drilled shafts or load transfer mechanisms, foundation elements, and drawings according to Subsection 104.03(b)(2). Do not begin remedial work until drawings have been approved by the CO.

Add the following:

Do not proceed with installation of subsequent shafts until approved in writing by the CO.

Approval to proceed with the construction of subsequent shafts will be based on observations of workmanship during construction of the shaft and the following:

(c) Contractor's conformance with the approved shaft installation plan;

F-22 DIVISION 550

Project: WA KITTITAS 5880(1), Dickey Crk Bridge

(d) Contractor's daily reports and inspector's daily logs of excavation, rebar, and concrete placement; and

(e) Concrete placement logs and volume curves.

The CO will provide written notification to proceed with subsequent shaft construction within 24 hours after completion of the shaft. If the CO determines the shaft to be of questionable quality, discontinue shaft construction and submit a new construction plan. Do not continue shaft construction until approval is received. After the first drilled shaft has been accepted, do not change construction methods, equipment, or material used to construct subsequent shafts, unless otherwise approved.
