Behold the latest PEMB marina drystack storage building at Harbour Isle near Anna Maria Island, on the gulf coast of Florida. From a simple concept, I designed the building for both aesthetics and function. I worked with the manufacturer every step of the way, and managed the erection, concrete, plumbing, electrical and sprinkler systems. This included implementing customized changes in the foundation and fire sprinkler design for optimum efficiency, resulting in substantial savings for the client.

About David Coyle, President, Mack David Buildings

I have more than 30 years of experience in the pre-engineered metal building (PEMB) and construction industry, which includes operating my own erection company for almost 12 years. Having erected many different brands of metal buildings I bring extensive knowledge to my customers, know builders, and quality builders’ systems, and my design background lends itself to a more aesthetically pleasing metal building as well.

Contact me for future PEMB quotes. After you receive the quote, I will be more than happy to come to your office and sit down with you to go through each line item. I can also help when trying to compare multiple quotes to make sure there are no hidden costs or missing items that may turn into change orders once the project has begun. I really care about helping customers and I believe in building long-term relationships.

When comparing quotes, it is vital to look at more than the bottom number; to really evaluate at all the major components and compare things like:

  • Collateral load, wind speed, and exposure
  • Importance factor and enclosure factor
  • Type of roof and gage, type of wall and gage, and Kynar vs. SP for color
  • Deflections for roof panel/wall panel/purlins/girts/frames, endwall types, bracing type, etc.

I can provide expertise in all aspects of your PEMB project, for all types of building structures:

  • Marina boat dry storage buildings
  • Aircraft hangar buildings
  • Warehouse buildings
  • Churches, shopping centers and more
