Demolition costs go up due to asbestos
The ancient Greeks named the silicate materials “asbestos” because the name meant “inextinguishable”; and, they knew asbestos had harmful biological affects but evidently forgot to pass the word.
In today’s world, asbestos eats up a city budget faster than flames. The fibrous material is considered a serious health hazard and Building No. 39 at the city airport had plenty of it.
At this week’s council meeting, City Planner Dave Shafer recommended a resolution to approve the first change order in the Building No. 39 demolition project.
Shafer said the change order included three changes. The contract was awarded at a base bid of $239,500 to Affordable Hazards Removal Inc.
Access to the basement and steam tunnels wasn’t possible because the basement was flooded. The contractor pumped the asbestos-contaminated water from the basement.
Once access was possible, the consulting engineer completed an inspection to quantify and identify the amount of asbestos piping that had to be removed and the amount of asbestos-contaminated tunnels that had to be cleaned.
Shafer said the breakdown of the work needed and the costs was: removal of piping in tunnels and basement, $40,160; cleaning basement and tunnels, $12,590; and hauling costs to the landfill for C&J Bulldozing, $12,000.
Thousands of feet of piping were contaminated by the asbestos. Shafer said there were about 4,060 linear feet of piping throughout the tunnels and 960 linear feet of piping in the basement.
“The tunnels are located around the entire perimeter of the building and were used for all the steam pipes and utilities,” Shafer said.
Contaminated flooring in the basement and tunnels had to be cleaned and added to the change order.
Shafer said the hauling cost is additional and was discussed prior to awarding the bid. The additional $12,000 is the cost to truck non-contaminated acceptable debris to the landfill versus on-site fill at the airport.
The total change order of $64,750 makes the new contract amount $304,250, according to Shafer.
“The next lowest bid received from another contractor for the demolition project was $299,276, which was $60,176 above the base contract with Affordable Hazards Removal Inc.
