Flagler Street (800 MHz Trunked Radio and Microwave System Upgrade Project, B-74202), for the Department of General Services Administration, Communications Division. Funds for said increase are available from Capital Improvement Project No. 311052.429401.6.840, B-74202. Background Information: On April 8, 2004, as part of the 800 MHz Trunked Radio and Microwave System Upgrade Project, B- 74202, the City Commission adopted Resolution No. 04-0216 accepting Bid No. 02-03-187 with Sabre Communications Corporation "Sabre" for the removal of an existing guyed tower, purchase and delivery of one (1) new 125-foot self-supporting radio tower with ice bridge, including construction and antenna installations, for Fire Station No. 11 located at 5920 W. Flagler Street, in an amount not to exceed $98,963. As part of the project, Sabre completed a subsurface evaluation that provided general site information and soil parameters for foundation design calculations. The subsurface soil evaluation revealed that in order to properly support the tower based on the original mat and pier foundation design (a mat of concrete/pedestal type) an increase in foundation surface area would be required. As a result, this increase would exceed the specified space availability and intrude into setback requirements. In addition, the original mat and pier design would increase in price from an estimated $19,474 to $36,700. Sabre recommended that a caisson design (drill shafts dug down and filled with concrete) be used which would result in the smallest cost increase to the City and would not require an increase in foundation surface space. On December 9, 2004, Resolution No. 04-0780 was adopted authorizing an increase in the amount of $8,245, increasing the contract from $98,963 to $107,208, to pay for the redesign of the tower foundation. This new request for an additional $3,500 is necessary to pay for unforeseen foundation material cost increases. During the course of work, Sabre was advised by their foundation subcontractor that project costs had increased by more than 15% from the original quote. These costs reflected increases in fuel, concrete, and rebar. Staff from the Purchasing Department reviewed Sabre's change order request and forwarded a market conditions survey to the second lowest bidder, Expert Construction Managers (see Attachments "A-1" & "A-2"). The second lowest bidder clearly stated that their bid would have to be increased by $6,000, from $109,900 to $115,900. Based on this information, the Purchasing Department concluded that Sabre's proposed increase is reasonable. Budget Impact Analysis Is this item related to revenue? YES Is this item an expenditure?
