Board approves change order to finish Water's Edge culvert replacement after permit change and rising rental dewatering costs
Summary
Indian River County commissioners approved a change order on March 11 to finish culvert replacements at Water's Edge Phase 2 after the local water-control district required a larger reinforced concrete pipe and additional dewatering measures, which increased costs and delayed work.
Indian River County commissioners on March 11 approved a change order to complete culvert replacement work in the Water's Edge Phase 2 subdivision after an inspection by the local water-control district prompted a permit change that required a larger reinforced concrete pipe and additional temporary dewatering and sheet-pile measures.
What happened Staff explained that the project originally received permitting that allowed using a 43-inch corrugated metal pipe; the contractor had purchased and delivered that pipe. During a follow-up inspection, the Indian River Farms Water Control District's engineer told staff the earlier specification would not meet the district's expectations for conveyance under certain flood conditions, and the project therefore required a 48-inch elliptical reinforced concrete pipe (RCP) instead. The change required the county to purchase different pipe, to install sheet piles and to run temporary bypass dewatering pumps while portions of the canal were reconstructed. Those steps increased costs and introduced multi-month delays.
Cost drivers and board action Deputy/assistant solid-waste staff and the county's managing director for solid waste briefed commissioners on the overruns. They attributed the major cost increases to (a) the district's post-permit engineering requirement for a larger pipe, (b) the need to rent pumps and sheet piles during wet-season work to keep the site dewatered, and (c) adjustments to canal reconstruction standards requested by the district.
Commissioner questions focused on whether the county had legal remedies and whether the purchased 43-inch pipe could be repurposed. Staff said the 43-inch pipe had not been installed and remained on-site; it could potentially be used in other county projects or sold, but the county would still incur unrecoverable schedule and rental costs. County counsel and staff said litigation or claims against the district would be costly and unlikely to yield prompt recovery, so the board approved the change order to complete the job quickly and avoid ongoing rental costs.
Vote and next steps The board unanimously approved the change order and directed staff to complete the work, dewater the site, reinstall the approved 48-inch pipe, and restore canal banks to the district's standard. Staff will document costs and explore reuse or resale options for the unused 43-inch pipe to mitigate net losses.
Ending County staff said completing the work will reduce continuing monthly dewatering and rental expenses and restore the subdivision culvert to the district's standards; commissioners emphasized the importance of coordinating future permit inspections earlier in construction to reduce similar downstream costs.
