By Janine Davis Record Staff Writer Workers on a replacement sanitation line at Black Hawk Middle School last month encountered a new set of problems that have added to the scope of work and cost of the project.The total expense for the work is $42,841. At its May meeting, the school board approved a $29,672 bid from Heggemann Plumbing to replace a corroded sanitation line at the school. To minimize disruption during summer school and exposure to asbestos, workers extended the sewer line from the girls’ restroom away from the building into the parking lot. During the board’s June meeting, Facilities Director John Chandler told district officials that additional problems surfaced as the work progressed, requiring an additional $13,169 to repair. The main problem is inadequate sloping for a drainage line that runs from the kitchen and two bathrooms in the 1986 addition. “When we went in, we saw there was no fall in the line,” said Chandler noting that the International Plumbing Code calls for one-eighth inch in slope per foot. “We currently have 210 feet of drain with less than 1 inch of fall, and by code we should have at least 18 inches for proper drainage.” Chandler proposed, and the board approved, installing a sewer pit with a grinder pump and running a pipe with 30 inches of fall. A new gravity drain will be installed to accept pump discharge to improve sewage flow. In other board action, members approved the purchase of new walk-in freezers at Rebecca Boone Elementary and Black Hawk Middle School for $33,214 and $22,676, respectively. The vendor is Kohl Wholesale, which was the low bidder for each of the units. The board also approved renewal of a 12-month contract with SubFinder System, a popular application service provider that automates the process of finding substitute teachers through the Internet and phone. The contract sets a minimum monthly fee of $838.20, except for June and July. Angela Herbel, administrative assistant to the superintendent, said SubFinder is coming out with a software upgrade that addresses some of the district’s issues with the system and glitches that include new contacts for teachers who have already accepted a substitute job.
