Correction: Lisa Kassman's title has been corrected in the article below. Originally posted Oct. 16 at 9:41 a.m.: Katy ISD students at several campuses may see changes to their campuses by the end of the school year. These changes could include replacing air conditioners, moving portable school buildings and creating temporary workspaces while construction projects are completed on multiple campuses, KISD officials said at the Monday night work study board meeting. Mark Tiedt, executive director of facilities planning and construction for the district, said replacing air conditioning equipment at McDonald Junior High School as well as Bear Creek and Stephens elementary schools would cost about $1.6 million. The new air chillers will be paid for using 2017 bond funds, Tiedt said. “These chillers have met and exceeded their life cycles and will be replaced with higher-efficiency equipment,” Tiedt said. Installing the air conditioning equipment is expected to be completed by February, Tiedt said. The work will be scheduled around activities at the affected campuses. Lisa Kassman, the district’s construction project manager, said amendments to a contract with Anslow Bryant Construction would affect the timelines for additions and renovations to create the Katy High School Career and Technical Education spaces and athletic facility renovations. Kassman said the the amended contract includes providing portable buildings for the Katy High School coaching staff to work out of while school renovations are complete; relocating the weight room and training rooms; demolition; and construction. Construction should begin in February, she said, and be completed by next summer. An amendment to another contract with Anslow Bryant Construction for renovations to Fielder Elementary School will have similar results with portable buildings being moved to accommodate the work. Additionally, two more portable buildings will be installed on the campus to provide space while work is being completed, Kassman said. “Portable moves are being coordinated with campus administration to ensure that instructional time is not interrupted,” Kassman said. The measures may be voted on at the next KISD board meeting Oct. 22.
