Specification Changes:

a) The pole sounding data table is attached to the end of Section 01 00 00.00 13

b) Specification Section 01 78 02.00 10, paragraph 1.1 is changed as follows:

1.1 SUBMITTALS

Government approval is required for submittals with a "G" designation; submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. The following shall be submitted in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

SD‐11 Closeout Submittals Final Low Density Cellular Concrete Placement Quantity; G River Bottom Elevation Measurements; FIO

c) Specification Section 01 78 02.00 10, paragraph 1.2.2 is added as follows:

1.2.2 River Bottom Elevation Measurements

The contractor shall measure the river bottom elevations at each monolith joint on all sides of the guidewall structure prior to the start of any work on the crib structure. These measurements shall be submitted to the Government in tabular form for review and acceptance prior to starting work on the crib structure.

d) Specification Section 03 11 13.00 10 Table of Contents is changed as follows:

Paragraph 3.2.1 Formwork Not Supporting Weight of Concrete is deleted

e) Specification Section 03 11 13.00 10, paragraph 3.2 is changed as follows:

3.2 FORM REMOVAL

All forms shall be completely removed before project completion. Forms shall be removed in a manner which prevents injury to the concrete and ensures the complete safety of the structure. Forms shall not be removed before a compressive strength test result (See Section 03 60 70.00) shows a minimum of 75% of the specified compressive strength is achieved or before seven days after placement, whichever is longer. Any additional concrete compressive strength cylinders and tests the contractor chooses to perform to determine acceptable form removal, beyond those described in Section 03 60 70.00, shall be at no additional cost to the Government. Where forms support more than one concrete placement, the forms shall not be removed until this form removal criteria is met by all supported concrete placements.

W912ES-15-B-0011

The Contractor may request permission to use maturity instrumentation instead of control cylinders to determine the compressive strength of the concrete. ASTM C 1074 procedures shall be used for estimating concrete strength by means of the maturity method. All expenses associated with instrumentation of the concrete and evaluating the strength using maturity relationships shall be the responsibility of the Contractor at no additional cost to the Government.

f) Paragraph 3.2.1 from Specification Section 03 11 13.00 10 has been deleted.

g) Specification Section 03 60 70.00, paragraph 1.2c is changed as follows:

4. Any conveyances left in place as embedded are filled with concrete, with no voids remaining.
