SUBJECT: Crystal Springs Emergency Surface Water Repair
Project No. 91641206
BID AWARD
ISSUE
Award a contract for the construction of the Crystal Springs Emergency Surface Water Repair to Hoffman Construction Inc.
BACKGROUND
Maintenance staff was notified of pavement settlement within Crystal Springs Park and 51st Ave S during the week of July
18, 2016. Using video inspection, it was determined that the surface water pipe was filled with a large quantity of material
that indicated a possible failure of the pipe. Crews attempted to remove the blockage, but the removal of the material lead to
additional failure of the pavement and a sinkhole. Other utilities are located within the settlement area.
The Mayor declared an emergency on July 21, 2016 and Council approved Resolution 1887. Frank Coluccio Construction
stabilized the emergency repair by filling the sinkhole, securing the utilities, and installing a bypass pipe. KPG was hired to
design the permanent repairs for construction in 2016.
DISCUSSION
The Crystal Springs Emergency Surface Water Repair project was advertised for bids on August 30 and September 6, 2016.
Nine bids were received and opened on September 13, 2016. The bids were checked, tabulated, and two errors were found
and corrected. Hoffman Construction, Inc. is the apparent low bidder with a bid of $203,361.00. The Engineers Estimate was
$251,065. Hoffman Construction Inc. has not performed previous work for the City, but has successfully completed other
municipal projects.
BUDGET AND BID SUMMARY (All amounts include sales tax)
Funding is proposed from the 2016 Annual Small Drainage Program, as only one bid that was over budget was received and
rejected by Council by Resolution 1886.
