The Glen Rose Independent School District's board of trustees Monday night chose to use a “construction manager at risk” method for building a planned new arena and other projects approved in a May bond election.

It also released new renderings of the outside and inside of the 2,000-seat arena. See them on pages B2 and B3 in the Sports section.

A construction manager at risk is a sole proprietorship, partnership, corporation or other legal entity that “assumes the risk for the scope of work approved at the contract price as a general contractor and provides consultation to the school district regarding construction during and after the design of the facility,” according to the Texas Education Code. It requires the contractor to publicly advertise and receive bids or proposals from trade contractors or subcontractors and provides the contractor and the district will review those bids and proposals.

The contractor also will work with the architectural firm, PBK Architects, during the design phase.

“They will give us a guaranteed maximum price,” Superintendent Wayne Rotan said of the construction manager. “Each phase requires competitive bidding for things such as concrete work and electrical work.

“It gives us more flexibility over subcontractors' work,”  he added. “This way we get to see all the bids.”

Voters overwhelmingly approved a bond issue of  $19.995 million to build the new arena, renovate the existing gym for an expanded band hall, expand of the ag barn where students raise animals and upgrade technology throughout the district.

The arena is expected to account for most of the expenditure, about $16.9 million.

Rotan said the district will begin publicly advertising for the construction manager at risk job next week.

“We hope to hire one in July and still hope to start construction in December and finish by May 2012,” Rotan said. “We're in the design phase in all three projects.”

In other action, the board approved the Somervell Central Appraisal District's 2011 budget of $567,608. It represents a 8.51 percent increase, or $28,997, to GRISD.

The district pays about 65 percent of the CAD's total budget based on the amount of taxes levied. Its portion is $369,570. GRISD also pays to the Hood County Central Appraisal District since the district covers a small portion of Hood County.

The board also approved the hiring of Shannon Bage as an elementary/kindergarten teacher; Areli De Reza as an elementary/first grade teacher; Bonnie Spies as an elementary/special education teacher; and Charla Arendt as an athletic trainer/teacher.
