LTC 261-2006 Emergency Construction Contract for 12" Water Main along State Road A1A and Indianc Creek Drive from 63rd Street to 67th Street ~ MIAMI BEACH OFFICE OF THE CITY MANAGER NO. LTC # 261-2006 LEITER TO COMMISSION FROM: Mayor David Dermer and Members of the City Commission Jorge M. Gonzalez, City Manager .J ~. October 31,2006 U U Emergency Construction Contract for 12" Water Main along State Road A1A and Indian Creek Drive from 63'" Street to 67'" Street TO: DATE: SUBJECT: This Letter to the Commission is to inform you that we have awarded an emergency contract to Ric-Man International, Inc. in the amount of $517,000.00 for the installation of 2,350 linear feet of a 12" water distribution main and all the lateral water service lines on Indian Creek Drive from 63'" Street to Abbot Avenue. The water line is in the construction zone of the 63'" Street Flyover project. Ric-Man International was selected by the City because of their proven City construction project success, their specific skill in utility and underground work and their immediate availability to commence work. During the Flyover project design phase, the City provided existing utility drawings that correctly identified the location and depth of our water line. The City also participated in several utility coordination meetings with FDOT, the project contractor and other utility providers to address questions concerns and possible conflicts in the construction zone. Unfortunately the need to relocate the water main was only identified when the final roadway grading elevations were being worked by the FDOT contractor. The Florida Department of Transportation (FDOT) roadway reconstruction activities have revealed that the existing City 8" water distribution main is inappropriately shallow for the final project grades. Vibrations resulting from construction machinery have caused this 1950's era line to break at existing joints, producing sporadic and repeated leaks along the line. The line is a cast-iron water main with lead joints which is susceptible to cracking under excessive loads and vibration. The shallow location of the pipe is also not conducive to sustaining repeated load impacts and will continue to be problematic if not replaced. This water line provides potable water and fire suppression flows to residents along Indian Creek Drive, and at this point in time, any delays to the relocation of this water line would present a risk to the health, safety and welfare of the City residents through adverse impacts to normal and required water flow and pressure. 2 Timing for the replacement work as it relates to the 63rd Street Flyover project is also critical to and a further basis for the emergency contract. The FDOT reconstruction project is moving with an aggressive timeline, as requested by the community, to finalize the Indian Creek Drive portion of the project before year's end and thus restore normal traffic flow conditions. Prompt replacement of the water line will allow FDOT to minimize project disruption. The relocation expense for the water line is the responsibility of the City as the owner of the utility within the FDOT right of way. This responsibility is similar to the City requirement for utility owners in City right of way, such as FPL, to assume relocation expenses as required. The project awarded to Ric-Man International Inc. has been awarded in two phases. Phase I, the installation of the water main from 63'" Street to 65'h Street shall be substantially completed by November 10'h, 2006. Phase II, installation of the water main from 65'h Street to Abbot Avenue shall be substantially completed within sixteen (16) calendar days from the issuance of the second notice to proceed. The City has incurred additional expense for the project in order to provide for a second work shift and the construction phasing that will expedite the water line project. At this time FDOT has not informed the City of any delays to their contract and they would most likely not be able to have a good estimate until Phase I of the water main installation is completed. Given the City's prompt response, FDOT has agreed to indemnify and hold the City harmless for any delays attributed to the relocation of the water main along the Indian Creek Drive Corridor.
