“(f) The Contractor is advised that access through the Petrex yard will be shared with Petrex for the duration of the contract. The Contractor shall, at no time within the duration of the contract block or cut off access to Petrex. The Contractor shall coordinate all ingress and egress with Petrex, on construction access within the Temporary Construction Access Easement, as shown on Sheet C-6 of the plans.”

2. Page 22, paragraph 17, subparagraph (b). Delete this subparagraph in its entirety and substitute the following therefore:

“(b) Vibrations shall be limited to a peak particle velocity of 0.25 inches per second at the nearest structure. When vibrations from construction operations have exceeded the limit, the Contractor shall take immediate action to reduce the vibrations to acceptable limits. For the Petrex Compressor Building, located within the “NO WORK AREA”, as shown on Sheet C-11, allowable vibrations shall not exceed 1.0 inches per second due to the proximity of the building in relation to construction activities for the N-1 Option Area. Note that the 1.0 inches per second, is limited to Petrex Compressor Building only. All other facilities shall adhere to the 0.25 inches as stated above. Disposition of the Petrex Compressor Building, near N-1 monoliths 101- 110, will be noted as “DO NOT DISTURB”.”
