Morgan High School Addition
Project Confirmation Number:
55 North 200 East
Morgan, UT USA 84050
Brief Description of Project:
Having exceeded its capacity, the Morgan School District expanded Morgan High School with a $19M, three-story addition to the existing school. The approved design will add 83,000 square feet which includes a larger and more functional administration area, double the cafeteria size, double the kitchen size, and add 25 classrooms.

Explain the Project and its Use of Masonry Materials and Techniques:
Aesthetically, and because the addition is located in the front of the school, the addition gives a new identity to the school that ties back to its original building, as well as the historic buildings across the street at the middle school.
Some specific veneer challenges faced during this project was working during the winter season from November-March. This proved difficult with walls going 44’ in the air and at the mouth of Morgan Canyon, due to low temperature and high wind speeds. The veneer was stack bond with raked joints, which made us have to maintain plumb joints up to 42’, with a 2’ precast banding that topped off most walls at 44’. This proved to be extremely difficult because of the low temperatures. The mortar never hardened after laying, so when it came time to go back through and rake the joints, the CMU veneer walls would want to roll around on the masons.
Through much of the job there were two block wide sections stacked 20’ high with full day’s worth of work and mud never hardening. Masonry veneer structural columns were two blocks wide, stack bond. This made it challenging to maintain plumb and correct width for placement of a 1,500 lbs. precast column cap that topped out at 46’4”. On the west side of the building there is a section of modular brick with a 12’ 3” x 16’ letter M brick design. This proved to be challenging to make sure all the accent brick were in correct configuration.
With the job site conditions, this made a straightforward structural CMU project rather difficult. Building onto the existing school left very little room for the masonry work. On the east side of the project, there were 300’ linear feet of scaffold that had to be placed on the roof of the existing building. This scaffolding had to be used by many trades, including: for placement of lintels, wood around windows, air barrier foam, masonry veneer, masonry washer, and calking all precast and joints.
With having such a small site, the laydown area had to be offsite from the project, having the mason haul 480,000 lbs./240 tons of precast from a half of a mile away. Eighty percent of the scaffold had to be placed on the interior of the school. Having to use a crane for the project as well as having to tear down scaffolding at floor heights and re-set up scaffold after the steel and floor had been placed was another challenge that was met.
