PART 2 PRODUCTS

MATERIALS

Equipment Type, Load Carrying Device, Load, and Instrumentation: Conform to ASTM D1143 [and][.] [ASTM D3966.] [ASTM D3689.]

QUANTITY

Provide [one] [___] test crib for pile load testing.

PART 3 EXECUTION

EXAMINATION

Verify that site conditions will support cribbing and load for testing purposes under provisions of Section [01039.] [_____.]

PREPARATION

Establish stable working elevation for test equipment.

TESTING

Perform load tests.

Load test to the following criteria:

[Test [6] [___] indicator piles at locations as directed.]

One test for first [100] [___] piles.

One test for next [250] [___] piles.

One test for each [500] [___] piles thereafter.

Subject piles to [1-3/4] [2] [___] times design load.

Acceptable Permanent Set of Piles After Load Testing: [1/8] [1/4] [___] inch ([3] [6] [___] mm).

If tested piles do not conform to requirements, perform additional testing of other piles, at no cost to the Owner.

FIELD QUALITY CONTROL

Field [inspection and] monitoring of testing will be performed under provisions of Section [01400.] [01410.] [_____.]

An independent inspection firm will be appointed by the [Owner] [Contractor] and remunerated by the [Owner] [Contractor] to observe and document test method and results.

Document test equipment used, method of calibration and recording, test results, recommendations or modification of piling method used.

Accurately record actual locations of tested piles and movement or distortion caused by testing.

EQUIPMENT REMOVAL

Dismantle equipment; load, and remove from site.
