| BACKGROUND: |
Meeting in regular session on April 5, 2012, the Board awarded Contract PD 11-12.012 "69th Avenue North Drainage Improvements and Sidewalks Project" to Sigma Consulting Group, Inc. (Sigma). Sigma was tasked to provide engineering design and observation services as necessary to develop 100% construction plans for the construction of a stormwater system to alleviate flooding from 69th Avenue from Lillian Highway to Fairfield Drive and the surrounding areas/side streets.
Change Order #1 requested Sigma to prepare a maintenance map. Right-of-way acquisition was initially included as part of the original project recap. Legal descriptions and sketches were produced, but it became apparent that property owners were unwilling to donate right-of-way.
Change Order #2 was due to Sigma hiring the Constantine Engineering Group to perform subsurface underground investigation (SUE) work to include four potholes, asphalt cutting and patching, and survey work to locate vertical and horizontal utility locations.
Change Order #3 included supplementary design services for another 16-acre drainage basin at the south end of the project limits, to address drainage complaints on 69th Avenue. These supplementary services included waterline relocation design, valve engineering analysis, and drainage redesign to reduce construction costs and utility conflicts and to address all the drainage needs within the project limits.
Change Order #4 was not processed.
Change Order #5 was for time only, as the County added 365 days to the contract to cover construction and as-built certification, a delayed bidding process for construction, the April 29, 2014, storm event, funds not being readily available, and division of the project to satisfy FDOT work on Fairfield Drive.
Change Order #6 is requesting additional funds of $44,215.00 to Sigma to provide additional services for design of an overland outfall between two private residences at the east end of Devonshire Circle, both of which experienced flooding during the April 29th storm event. Sigma will also provide additional services to design a positive discharge system that will prevent flooding near residences on Colonade Circle and 65th Avenue. This system will discharge to the new drainage system, designed by Sigma, that is being installed on North 69th Avenue. Easements for Devonshire Circle have been signed and acquired. We have received verbal willingness responses from the property owners for the easements on Colonade Circle and anticipate recorded easements upon completion of processing by our real estate staff. Additional construction administrative services are necessary to complete the 69th North Drainage Project and are also included with this request. The total amount for change orders, including Change Order #6, is $65,375.00. The original contract fee was $144,220.00. With this additive Change Order, the new contract fee will be $209,595. |
