7. QUESTION: PVC Conduit: The plans call out a 2-1/2" PVC conduit to encase the tie rods.

The specifications call out a 6" material for encasing the tie rods. Which one governs?

ANSWER: The required PVC diameter for tie-rod encasement is as shown on the plans (2.5" dia) except at turnbuckle locations where no PVC encasement is required. The specs are changed via Amendment 0002 to exclude the PVC diameter requirement. Plans should be referenced for the required diameter.

8. QUESTION: We would like to inquire about possible access to the south portion of the project via Lake Lane and Barge Rd. During our site visit it was noted that there is a 6 ton weight limit on Lake Lane. Is it possible that those restrictions will be lifted to accommodate the project?

Also, it was noted on Sheet 1 of the drawings (Note #7) that there is a 150 psf surface/surcharge load limit on the existing revetment sections. Is there a setback distance that needs to be maintained for equipment and materials from the existing section? Our initial assessment of the project would be to perform a majority of the work from land based operations. Is it the Corps of Engineers intent to construct this project from marine plant?

ANSWER: No changes will be made in this regard to the plans and specifications. Methods of construction are left to the discretion of the offerors.
