The city chose Waterloo company Cardinal Construction to complete lobby renovations on the center, Anderson said. The company is already working on other renovations to the facility.
Cardinal Construction will spend about $5.5 million to complete the project, Anderson said. The city received bids from four companies that all set their highest bids above $6 million. All companies provided alternate bids at lower rates. Other bidders for the lobby renovation were Henkel Construction Company, Larson Construction Company and Pro Commercial, LLC.
Anderson said Cardinal Construction provided a deduction from its original base bid of more than $692,000 for additional footings, and it proposed adding piers to the parking area for safety reasons.
The city engineer’s original estimate for the lobby renovation was $4,400,000, more money than will be allotted in new general obligation bonds. Anderson said the city can lean on other bond money it received for capital projects in recent years, likely including the $3.7 million in bonds for convention center work the Council approved in June.
Anderson said the gap between the estimate and actual cost for lobby renovations might be due increased product costs from COVID-19 and the destructive derecho that hit parts of Iowa. He added that there may be higher costs than anticipated for contractors to move their equipment in and out of the convention center when events are booked in parts of the building.
