Project #7 – 1970’s Roof and Air Conditioning Systems
Project #7 – 1970’s Roof and Air Conditioning SystemsThe approximate cost of this project = to exceed $250,000
(Please note the numbering of this project does not indicate its priority, it only identifies the project for reference.)
This project is made up of various replacements such as:
- Replacement of aging Roofing Systems – the majority of Trinity’s building roofs were constructed or re-roofed at the time of the 1988-90 addition. During this time period, Trinity’s Sanctuary was expanded as well as the addition of the Information Lobby and the Three Story Wing of our building. Although we’ve been unable to locate all of the roofing history, it appears as though with the intersecting of many roofs, the majority of them were last roofed during the 1988-90 construction. The existing roofing membrane and its bonding properties have reached the end of their service life. We are continually making repairs to the roofing. However, given the age and condition of the existing roof, contractors will not warranty their repairs.
- Replacement of the 1970 Wing Air Conditioning System – Over the 1970’s Wing of the building there are 19 A/C units. Because many of the A/C System components are dated, we know that the majority of them were installed in 1991. Since that time, Federal Regulations have required the A/C manufacturers to produce units to higher energy standards and with more strict ozone depleting cooling gases. The modern A/C systems operate more efficiently and use coolant gases which are not compatible with the older systems. What this means is as each year passes, when an a/c unit fails, it is getting harder to find compatible equipment and coolant gases; resulting in a higher repair cost. Also, because the newer A/C systems are not compatible with the older equipment, they will require their entire system replacement (i.e. all piping from the rooftop to each classroom below and their in-room mechanical components). Before this project can begin we intend to hire a Mechanical Engineer to properly size the new systems and make recommendations for the best application for our facilities. There are also multiple Ventilation/Exhaust Fans that are in need of replacement. Because the replacement of the roof will require the disconnecting of all these mechanical systems, it is the ideal opportunity to replace them.
