Sitting on a peninsula that consists of over 2000 acres of forested land, holding 26 transmitter towers and a handful of support buildings, this federal facility located in northern Maine was commissioned on June 23, 1961. Built with the mission to provide communication and navigation to Naval fleets ranging from the North Atlantic Ocean, to the Arctic Ocean and Mediterranean Sea. The security and surroundings of this operation were picked and executed very precisely in order to keep operations running smoothly as this facility is the backbone of the submarine broadcast system and a very important part of Naval communication.
Because of the importance of this peninsula, it is crucial to make sure all buildings and transmitter towers are preserved properly in order to maintain the highest frequency output in the world. To maintain these towers and buildings a lot of steps are put in place to get the best quality out of these systems. This is why daily inspections, frequent shutdowns and great communication are vital to keeping this operation running proficiently.
Weather is always a major concern while venturing this far into Northern Maine; having the facilities located on a peninsula can bring extreme weather conditions and severe cold in the blink of an eye. This is an issue when it comes to the work being performed on the facility because most cementitious products have certain cure temperatures and can’t be subject to rain. Along with the weather issues, there are certain areas within this facility that require a shutdown in order to safely perform the work needed. All these issues required our team to be extremely aware and have precise planning while navigating this project. Although some setbacks were run into throughout this project, we completed all work in a timely manner while fighting against the biggest beast of them all, Mother Nature.
Hascall & Hall was brought into repair voids in the concrete exterior façade, to clean and coat the entire exterior façade and to infill old and deteriorated masonry units. As stated above, this building was commissioned in 1961 located on a peninsula in northern Maine, so the extreme weather it endures daily has a huge effect on the façade. While sitting there for over 50 years this building had deteriorated tremendously and was due for a quality Hascall & Hall restoration job.
We started this project by spraying a cementitious cleaner on the entire façade followed by a pressure wash to remove all the unwelcome grit and grime. This was crucial in the beginning to really get a sense of what the deterioration had done, as well as being able to see the exact canvas that we were working with. There were many parts of the exterior façade that had been spalled and cracked which had forced the concrete out of the wall resulting in voids and missing sections of the façade. Because of the extreme climate this building endures, these voids needed to be addressed immediately before cold weather hit and further damage could be done. The unusual shape of the exterior wall forced our team to build forms to make sure our repair work would perfectly mold to the existing wall. Once forms were made and concrete pours were complete the exterior wall became whole again.
Along with the concrete infill there were also a few sections of masonry infill that needed to be done throughout the building. These were existing vents in a few select locations that were taken out and replaced with masonry units to close the void. Although these spots were not deteriorated or cracked, these spots had copper vents previously in place which no longer served a purpose for the building and were replaced by block. Lastly, after everything had been cleaned, formed, patched and all masonry units were replaced, the coating of the exterior wall was due. The entire cement façade of this building was then painted with two coats of cementitious paint. This paint covered existing voids on the wall as well as changing the 50-year-old cement façade to look brand new again.
