City of Tukwila Public Works Department - Henry Hash, Director INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committee FROM: Henry Hash, Public Works Director / ,$- BY: Ryan Larson, Senior Program Manager CC: Mayor Ekberg DATE: August 10, 2018 SUBJECT: Surface Water Fund - 2018 Annual Small Drainage Program Project No. 91841201 Bid Award ISSUE Award a contract to Ceccanti, Inc. for construction of the 2018 Annual Small Drainage Program. Allan Ekberg, Mayor BACKGROUND The Small Drainage Program constructs drainage projects throughout the City that are too large for City staff to complete but are smaller than a typical capital improvement project. The projects originate from citizen complaints and maintenance staff recommendations and are compiled on the Small Drainage Project List. Each year the projects are prioritized based on need, expense, permitting requirements, and length of time on the list. The highest priority projects are then designed and constructed. The 2018 Annual Small Drainage Program was advertised to provide drainage improvements at up to five locations as noted in the attached vicinity map. DISCUSSION The 2018 Annual Small Drainage Program was advertised for bids on July 17 and 24, 2018. Three bids were received and opened on July 31, 2018. The bids were checked, tabulated, and no errors were found. Ceccanti, Inc. is the apparent low bidder with an overall bid of $543,836.40. The engineer's estimate was $491,868.00. FISCAL IMPACT (All amounts include sales tax) The 2018 Small Drainage Program has Surface Water construction funds budgeted at $515,000. Construction management (CM) is budgeted at $80,000, but will be completed by in-house staff, so $35,000 is now being allocated for construction, with the remaining budget available for consultant support. In addition, The King County Flood Control District included $65,378 in their capital budget for the South 180th St Flood Wall Extension, which is part of this 2018 Small Drainage Program. The cost of the flood wall site is eligible for reimbursement based on the bid results, estimated to be $50,000.
