2 wells added to plan, pressurized line removed

Work on the Cassville Intermediate School renovation project is in full swing, and parts of the project have changed from the original plan, adding about $500,000 in flood mitigation costs.

Richard Asbill, Cassville superintendent, said the district voted to add two more pier wells to the original one, and it has removed from the plan a pressurized line that was determined to be unnecessary to prevent flooding in the building.

In December 2015, the intermediate school had 2-3 inches of water come into the building following a heavy rain, affecting a total of 10 rooms, including six fifth-grade classrooms, an English Language Learners classroom and the nurse’s office.

The original bid for repairs, awarded to Construction Services Group, of Neosho, came in at $1,564,168.50. Anderson Engineering is serving as the project engineer, and Paragon Architecture is serving as the architectural firm. Both have been working on the project since the flooding occurred.

After some duplicate items were removed from the bid, the initial cost was dropped to $1,462,301, of which about 75 percent will be covered by insurance. With the change orders, the total project cost is $1,975,072, as the three pier wells cost $630,183, and removing the pressurized line resulted in a deduct of $117,412.

“We did away with the pressurized line and incorporated what it would do into the directional boring and pumping systems, capturing the water and taking it away from the building,” Asbill said. “We also added the two additional pier wells, one on the northwest side where they are working now, and one on the southwest side. The original pier well will be in the alcove between the cafeteria and the third-grade hallway.”

Asbill said with the additional mitigation costs, the district will be on the hook for about 50 percent of the total project, and insurance will pay the other 50 percent, which covers returning the area to its previous configuration. The district’s portion of the payment will come out of Fund 4, the capital projects fund, which has a balance of about $2.8 million.

Work on the project is progressing, with crews currently installing the first pier well and excavating all the rooms to install the French drain system.

“Once the French drains are installed, they will start backfilling with clean rock and doing the directional boring from outside, which will connect to the drains,” Asbill said. “Then they’ll put in the drainage system around the football field, repour concrete in all the classrooms and start putting the rooms back together.”

The project has a completion date of Aug. 1, as long as weather does not slow the work.

Asbill said the district has also asked for additional funding from the Federal Emergency Management Agency, ands the district recently received a response from FEMA asking for additional documentation in about 12-14 areas.

The school got a close-up look at what happens underground during heavy rain events this week, as nearly 3 inches of rain from Thursday to Saturday led to some standing water in the work area of the intermediate school’s lower level.

Dusty Reid, director of facilities and operations at Cassville schools, said water got as high as about 14 inches under the top of the slab.

“With the size of pipes we have going in, I’m confident we are moving in the right direction,” he said. “We will be draining water from below the building well below it reaches the slab.”

Reid said having so much excavation done in the school helped to see what actually happens underground, adding that rain events like last week’s and the water it brought would have previously gone unnoticed.
