Bid Tabulation Budget Source of Funds Fund 038 (transfer to Fund 015) Account: 015 -9892- 706 -1100 Amount Budgeted: $360,000 Amount Requested: $303,431.25 Budgeted Item: YES SUMMARY & RECOMMENDATION In September 2010, City Council approved a budget of $360,000 to constrict additional wooden bulkheads at various locations throughout the course. A request for bid no. 11029 was submitted to thirty -three (33) constriction companies and three (3) plan rooms with four (4) bidders submitting a proposal. Crawley Shoreline submitted the low bid of $275,912.25, which includes the base bid plus Bid Alternate No. 1. The base bid encompasses the constriction of approximately 2,383 linear feet of bulkhead and the excavation of 4,450 cubic yards of earthen material. Alternate No.l addresses the disposal of the excavated material. Crawley Shoreline demonstrated their professionalism during the recent reconstruction of the Sylvan Beach Pier. Since Crawley Shoreline submitted the low bid and has an excellent working relationship with the City, staff recommends authorizing the City Manager to enter into a contract with Crawley Shoreline in the amount of 275,912.25 plus a 10% constriction contingency in the amount of $27,519, for a total contract amount of $303,431.25. Project Benefits, Liabilities and Annual Operation Cost When the course was constricted in 1988 the ponds had an approximate water depth of 5' -6', whereas today due to erosion, 2' -3' is an average depth. Over the years the erosion has not only naturally evolved but the speed at which the erosion has taken place can be attributed to a family of rodents (nutria rats) as well. In the area of Green Seventeen, about 7 -10 feet of bank has been lost to erosion. The City could defer the installation of bulkheads for future years; however in doing so, the erosion will continue and the unit cost to constrict will likely increase. The bulkhead unit cost in 2009 -2010 was about $80 per linear foot, whereas the low bid unit price this year is $84 and the 2nd and 3rd bidders came in around $95.
