1. Page 2, subparagraph 1.1.1(1). Delete this subparagraph in its entirety and substitute the following therefore:

“(1) The concept for maintenance and diversion of stormwater is that dry weather flow will be blocked from entering the immediate worksite during construction operations by the use of self-eroding dams (Soft Dams). The dry weather flow must be bypassed around the worksite, as needed, using gravity piping or pumping. During rain events, the soft dams shall either be removed at the direction of the Contracting Officer or washed out allowing wet weather flow to flow unimpeded, through the worksite to avoid flooding of streets and other areas outside of the construction project.”

2. Page 6, paragraph 1.9, subparagraph 2. Delete this subparagraph in its entirety and substitute the following therefore:

“2. The diversion system shall be designed to provide continuous drainage of dry weather flow of the existing canal system, and of the existing drainage structures which shall be disconnected during construction of the new General De Gaulle Drive Canal.

The pile cushion may be of solid wood or of laminated construction, completely cover the top surface of the pile, and be retained by the driving helmet. Minimum thickness of the pile cushion shall be 3 inches and the thickness shall be increased so as to be suitable for the size and length of pile, character of subsurface material to be encountered, hammer characteristics, and the required driving resistance.”
