Work is currently underway to replace and repair the masonry mortar joints on the McLeod Tower. Also, repairs are being made on the roof parapet. The roof parapet is the low protective wall or railing along the edge of a raised structure of the roof. The McLeod Tower opened thirty two years ago, on November 16, 1979. It is now time to prepare the building for the next thirty years. These enhancements will also provide a chance to make the building more energy efficient.
A common maintenance task for brick masonry is the repair of mortar joints, commonly known as ‘repointing.’ Removing deteriorated mortar from the joints of the masonry wall and replacing it with new mortar will restore the visual and physical integrity of the masonry work on the McLeod Tower. The most common means of water entry into a brick masonry wall is through de-bonded, cracked or deteriorated mortar joints. Repointing of the mortar will improve resistance to water penetration. Repointing deteriorated mortar joints is one of the most effective and permanent ways of decreasing water entry into brickwork.
The replacement of the existing roofing materials is expected to lower roof surface temperatures by as much as 100 degrees F. This work will result in improving weather proofing and energy efficiency. By decreasing roof temperatures, the amount of heat transferred into the building is reduced. Reducing the heat load transfer from the roof is expected to reduce peak load cooling demand by as much as ten to fifteen percent. The cost to air condition buildings is the sixth largest demand for all electricity generated in the United States.
This work is expected to take approximately four months. We appreciate your patience while we improve our facilities for patients.
