Durham Elementary and Intermediate School received a new heating and air conditioning system as a result of the February 2006 bond election. In addition, the project included site work to address ongoing drainage problems on that campus.
Following passage of the 2006 bond package, various consultants encouraged the Board to consider changing to a chilled water system rather than rooftop units at DEIS. After studying the issue over the course of several months, the CISD School Board agreed to modify the Durham project to include a four-pipe chilled water system. The changes resulted in additional upfront costs, but are expected to save the district utility costs long-term. In addition, CISD staff can do maintenance on the chilled water units, in-house. A similar chilled water system was approved for Carroll Senior High School.
PROJECT UPDATE as of November 2007:
HVAC Project: Air handlers for the new chilled water system were installed in the ceilings of each classroom. The handlers help manage the flow of heat and air as part of the campus' new chilled water system. The School Board voted to install the chilled water unit, which is a more cost effective and efficient system. The system was operational at the start of school and should provide CISD with significant long-term utility savings.
The masonry wall that surrounds the chiller unit has now been constructed as well. This bricked structure is located at the back of the campus near the Durham Intermediate School office entrance. The wall helps tominimize noise, make the area look nicer and protect pedestrian traffic from the chiller unit.
On Monday, November 26, CISD officials responded to the DEIS campus after reports that a defective part caused water to leak in the library area. Maintenance staff responded to the site to assist with the cleanup. Representatives from Swaim Construction were also on hand to determine the cause of the problem. The leak appeared to damage carpet and baseboarding, but initial reports show no damage to library books. CISD staff members are still assessing the situation and will report any damages to the contractor in the coming weeks.
Roof Project & Site Work: Summer rainfall caused significant delays on the DEIS roof and site work project. The site work was substantially completed just before the start of school and parents were able to utilize the new concrete driveway on the first day of classes. The parking lot drainage seems to have improved greatly since the project's completion. This was a long-standing problem at the DEIS campus that we hope has been alleviated with the site project from the 2006 bond.
The modified, bitumen roof has a low slope that allows for better runoff and drainage on the top of the building.
It had originally been the goal of CISD officials to remove green screens from the top of the Durham building. However, because there are still rooftop units over the common areas, city code restrictions will prevent CISD from removing the green screens.
Sewer Line: CISD Trustees approved an additional project at DEIS to repair a sewer line at the back of the campus. This project was not originally included in the bond package, but the line caused problems on the soccer field behind the campus during the spring semester. This project is now complete.
Covered Awning: If funds are available after completion of the February 2006 bond project list, school officials hope to present an additional project to the Board of Trustees for consideration. The project includes a proposed awning or covered walkway at the front entrance of the DEIS building.

This pictures shows one of the new classroom air handlers at DEIS. The new ceiling/duct work was part of a project to completely change the DEIS campus to a chilled water system. This type of system has been found to be more cost effective and efficient than rooftop units.

This picture shows the newly installed modified bitument roof at Durham Elementary and Intermediate Schools. The roof was entirely replaced as part of the 2006 bond package.

Durham's campus now has a new brick wall that surrounds the chiller units for the HVAC system.

The drainage site work on the Durham campus helps move water more efficiently away from the building.

Parking lot stripping at Durham is now complete. The project also included the installation of ballards at the front of the campus near the handicapped parking spaces.
