There are three types of anchored foundations: Type 1 with rock anchors installed at 60 degrees; Type 2 with rock anchors installed at 45 degrees; and Type 3 with concrete anchors installed at 45 degrees. Each type of anchored foundation will get performance tested for a total of three performance tests. The performance tests must be performed on the 50-ton bollard foundations. All other anchors must be proof tested. During the stressing of each anchor, a record must be kept of gage pressure and of anchor elongation at each stage of stressing to the specified test or Lock-off Load, as applicable. The Test Load must not be exceeded. Provide a qualified Professional Engineer to evaluate the anchor test results and determine the acceptability of the anchors in accordance with the criteria indicated herein. Provide the Professional Engineer Qualifications who will be performing the rock anchor test evaluations. Final acceptance of each anchor will be made by the Contracting Officer.

Performance tests must be successfully performed on two installed anchors before installing any additional anchors. Two additional anchors will be selected by the Contracting Officer for performance testing. A total of three performance tests must be performed with three additional performance tests to be identified by the Contracting Officer for a total of six performance tests;

therefore a total of eight rock anchors and four concrete anchors will be tested for the 50-ton bollard foundations. During the testing of each anchor, a record must be kept of gage pressure and of anchor elongation at each stage of stressing to each Test Load required by PTI DC35.1. Measurements of the elongation of prestressing steel must be made in accordance with PTI DC35.1. If the total movement at the end of 10 minutes at the Test Load exceeds 0.040 inch, the Test Load must be held an additional 50 minutes and the movement readings must be taken at the interval specified in PTI DC35.1, Paragraph 8.3.2. Test records, including plots and graphical analysis of test data, must be furnished upon acceptance of each performance tested anchor in accordance with paragraph SUBMITTALS.
