Quality Costs Top School Board Agenda



August 3, 2010 by Edward Leonard

As construction of the new high school moves into full swing the Clarke County School Board approved two contract amendments totaling $263K and intended to ensure that the products and services related to the facility are fully tested and meet contract standards. Meanwhile, on the construction site, Shockey Construction hopes to turn the large amount of rock being encountered into gravel, and possibly profits.

Gannett Fleming’s construction manager for the project, Michael Castelli, told the school board that progress was being made in many areas.

Rock Crusher Bound for Construction Site

“So far about 12 acres of earth has been disturbed and work has already begun on moving the waterline on the site.” Castelli said. “In about three weeks we’ll be installing fire hydrants at the construction site entrance and also at the intersection of West Main and Whitaker.”

Castelli estimated that the water line will be completed in about three weeks.

Completion of the water line will provide the construction site with more than just a local source of water for dust control and other miscellaneous uses. Shockey Construction plans to install a rock crusher at the north end of the property some time next week. Water is a critical ingredient in the gravel-making process.

“It looks like we may be able to use rock from the water outfall line to make gravel that can be used for the building pad” Castelli said. Castelli added the caveat that the gravel must meet a compaction rate of 95%. Compaction testing results for the site stone are expected next week.

If the site stone can be used to manufacture building pad gravel Shockey Construction will avoid both the cost of removing the huge amount of rock that appears to be just below the surface and also the cost of purchasing the gravel needed for the building’s foundation.

Castelli estimates that the stone crushing device will stay onsite possibly until early 2011.

The school board also discussed the possible inclusion of dozens of large concrete water pipes, already located on the property, in the storm sewer design. The pipes have been an eye-sore on the property for years.

School Board Chairperson Robina Bouffault instructed Castelli that the pipes should be used, if possible, because she has a verbal agreement from former property owner Alton Echols that the concrete pipes conveyed with the land. Bouffault said that the she was concerned that Mr. Echols may unexpectedly change his mind about the conveyance and send a truck to remove the pipes without notifying the school board and, thus, deprive the school of their use.

Castelli later said that the possible use of the large concrete sewer pipes was being considered but may not, ultimately, be cost effective. The more modern pipe already delivered to the site is made of plastic and is a different diameter than Mr. Echol’s donated pipe.

Whether the Echol’s piping is suitable to be crushed into gravel was not discussed.
