<br />Request for Clarification No. 1 <br /> <br />CITY OF SUNNY ISLES BEACH <br />CONSTRUCTION OF WALL UNDER THE WILLIAM LEHMAN CAUSEWAY <br />CITY RFP NO. 13-10-02 <br /> <br />To All Bidders: <br /> <br />Bidders for the above referenced project shall take note of the following changes, additions, <br />deletions, clarifications, etc. to the Plans and Specifications, which in accordance with the <br />Contract Documents shall become a part of and have precedence over anything shown or <br />described otherwise. <br /> <br /> <br /> Questions/Clarifications: <br /> <br />1. Is there a construction duration set by the City? This ties into the Liquidated Damages. <br /> <br />Response: Yes. All bids shall be based on the following construction duration: <br /> 90 days for substantial completion of work in accordance with the bid <br />documents <br /> 30 days for completion of work identified by City punch list <br /> <br /> <br />2. Is the size (diameter) of the helical piles specified (10” Ø) dictated by the over- <br />turning moment on the wall/footing? If so, what is the magnitude of that <br />moment? What is the actual vertical load per LF on the footing? <br /> <br />Response: The lateral load due to wind is 4.8 k and factored moment on top of pile 42.24 <br />k-ft. Assuming concrete wall, the vertical load on the footing per one foot wide of wall is <br />0.8 kips per foot of footing. <br /> <br /> <br />3. These 10” piles are rare (special order) and will be extremely expensive with long <br />lead time to get them made specially for this. Will other pile shaft sizes and <br />corresponding pile layout (configuration) be considered for use in lieu of these? <br />We know we can accomplish the req’d load requirements with perhaps more but <br />less expensive and more readily available smaller pile materials. So will other <br />solutions be considered? <br /> <br />Response: The Contractor may provide alternative quantity and size of piles, provided that <br />the proposed alternative design still meets the load requirements.
