PROJECT QUESTION: Clarify the area calculation for Steel Sheet Piling (Temporary) . . .

Question: Please clarify the area calculation for Steel Sheet Piling (Temporary) ? Type I for Wall N1 and Wall N2.

Response: Temporary walls N1 and N2 range in height from approximately 1 foot of retained earth to a maximum of 5 feet 10 inches of retained earth. Profiles for temporary walls have not been included in the bid documents. Bid quantity calculation for each wall is based upon a ratio of 3 (embedment): 1(retained earth) for steel sheet piling (i.e. a wall with 2 foot of retained earth would include approximately 6 feet of embedment totaling 8 feet of piling).
