SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

AMENDMENT 0006

The purpose of this Amendment is to provide the following:

1. PPI responses.

Reference Question Response

Page Section Paragraph

181 Section 2.4 Jet Grout Mix Design requires neat grout strength to exceed 1,000 psi at 28 days when tested in accordance with ASTM C109/C109M. This test method is for sanded grouts. The neat cement grout used for jet grouting does not contain sand. It is not generally subject to compression testing since it typically has a water/cement ratio exceeding 1.0 and is an unstable suspension.

In lieu of compression testing per ASTM C109, we suggest specific gravity measurements of the neat grout per ASTM D4380 be taken at routine intervals to verify the water/cement ratio of the grout prior to jet grouting.” How many test sections doe the test program require? Will the test program require test sections in more than one area?

Please see Amendment 0006.

testing and disposal for hazardous or contaminated groundwater generated during the construction processes such as dewatering?
