School of Concrete and Construction Management

Welcome to the School of Concrete and Construction Management.  We are glad you are here!

We invite you to explore our building and learn more about Concrete Industry Management and Construction Management.  We have several iconic design features that enhance student learning and allow us to share our love of concrete and construction systems with the public.  Throughout the building you will find QR codes that link to explanations and descriptions of several iconic features of our building.  We also have provided information on our many industry partners that donated generously to the creation if the spaces you will see as you walk through our building. 

The Virtual Tour and QR code tags were sponsored by the Associated General Contractors of Middle Tennessee.   We appreciate their support for this project.  Please stop in to SCCM 101 to speak with Brittany Thomas to find out more about our undergraduate degree programs in Concrete Industry Management Production Sales and Service, Concrete Contracting, Commercial Construction Management or Land Development and Residential Building.

The faculty, staff and students of SCCM thank all of our industry partners for their support of our programs, and a special thank you to Hoar Construction and Orcutt and Winslow Architects for their assistance in developing the QR Code Virtual Tour

Concrete Finishes

The SCCM Building utilizes a number of architectural concrete finishes including polished floors with blue and white aggregate chips in the main lobby, burnished concrete block walls in the main corridors, integral black dyed exterior precast panels, board form exterior precast panels, sandblasted exterior precast panels, and an artistic mural on a series of exterior precast panels made with laser cut release paper reverse placed in the bottom of the precast form bed.

Topping Out Ceremony Signed Beam

At the top of the atrium behind the ductwork is a structural steel beam signed by university officials, faculty, staff and students from SCCM, the designers, construction managers, and skilled trade workers on the project.  After signing, the beam was hoisted into place in a celebration of the completion of the structural elements of the building.  Placing the final structural member is called a “Topping Out Party” 

Topping out










Structural Systems

The SCCM building utilizes four different structural systems that have been left exposed throughout the building so that students can see the different systems and understand the assembly and connection sequences.  The four types are:

  • Reinforced cast-in-place concrete walls visible in the main lobby and atrium
  • Load bearing concrete masonry units with reinforced grout filled cores, visible in the corridors
  • Hollow core precast plank floors that span between the block walls, visible in the concrete labs. The planks are sprayed with an acoustic treatment on the bottom (the ceiling in the concrete labs) and a polished concrete topping slab on the top (the floors of the second floor corridors and classrooms in the east half of the building)
  • Structural Steel frame with composite deck and roof deck visible in Room 101 (structural steel columns and beams, open web bar joists, and metal roof deck) and in open ceiling out side of Rooms 228 and 229 (structural steel columns, beams and purlins with composite steel deck covered with 5 inches of concrete

Concrete Maturity Scanners

The builders embedded concrete maturity scanners in the grout-filled cores of the concrete block walls so that students can view the temperature and imputed strength of the grout as it cures.  The lead wires are visible in the corridor outside of classrooms 102 and 104.  The maturity monitor can be attached to the wires to get current maturity estimates, an example of which is available at MTSU-SCHOOL-OF-CONCRETE-AND-CONSTRUCTION-MANAGEMENT_CMU-GROUT_2023-02-01 (1).pdf 

Building Footings

The weight of the building and all of the applied loads from equipment and occupants must be transferred into the soils below ground.  The footings and foundations that transfer these loads are made from cast-in-place reinforced concrete with admixtures (chemicals) to make them less susceptible to freeze/thaw cycles and corrosive chemicals and minerals in the rocks and soils.  A section of the footing is visible next to the building near the outdoor classroom.

Monolithic Concrete Monument Stair

The main stair in the atrium is made of reinforced cast-in-place concrete that was cast monolithically (all at once) so there are no visible joints in the treads of landings of the stair.  A section of the steel reinforcing grid is visible on the underside of the stair riser near the windows of Room 104.

Mechanical Room Windows

In most buildings, the mechanical room is hidden, but the mechanical room at SCCM has viewing windows so that students can observe the operation of the building systems.  Visible from the first floor corridor on the west end of the building, students can see the boiler that heats water to heat the rooms in the winter, the intake pipes from the central chiller plant that chills water to cool rooms in the summer, the booster pump that creates water pressure for domestic use (sinks, water fountains, etc.), the hot water heater that delivers hot water to sinks, the expansion tanks that allow for pressurized water systems to remain at a near constant pressure, and the fire pump that keeps overhead sprinklers flowing in case of a fire emergency.  The domestic water pipes, heating and cooling loops, fire protection sprinkler loop, rain water leaders, and wiring for power, light and low voltage systems are visible in the open ceilings in many places throughout the building to enhance student learning of building systems.

Exterior Wall Assembly

 The exterior wall assembly is visible through a cut out panel in Room 201.  Students are able to see the exterior structure, the light gauge metal framing, the insulation and vapor barrier that protects the inside of the building from the outside elements

Heating and Cooling Assemblies

In many places through the building, ductwork and Variable Air Volume (VAV) boxes are visible through the exposed ceiling.  The hot and cold water loops pass through the VAV boxes to heat or cool the air that is ducted through the box.  The thermostats in each room signal the VAV boxes to put more or less air into the room to adjust the temperature.  The telemetry screens in Room 201 and outside the mechanical room allow students to see the water temperature in the heating and cooling loops, the fan speeds, the flow through each VAV box in the building, and other operational information in the building.  Just tap the telemetry screen to watch the display cycle through the parameters of each building system.

Viewing Windows

Each of the hands-on classrooms (other than the computer labs) have viewing windows to allow students and visitor to observe the projects and experiential learning opportunities that represent an important part of the SCCM Mission- to prepare students to become leaders in the construction industry by understanding safe, cost-effective, productive construction practices and processes while minimizing environmental impacts.

Reclaimed Wood

Construction of the SCCM required the removal of several red oak trees on the site.  As a way of demonstrating environmental stewardship for our students in an ongoing manner, we reclaimed the red oak trees to use on the learning stair that you see just outside the student project lab, the seating area near the main entry, the lattice backdrop in the program office, and the handrails for the stairs.

Green Roof

Another demonstration of environmental stewardship is the inclusion of a green roof visible outside the student lounge area on the second floor.  Green roofs reduce stormwater runoff and reduce the “heat island” effect of traditional roofs.  The roof is covered in shallow rooted succulent plants held in place by trays.  The SCCM faculty, staff and students are responsible for maintaining the green roof, representing another active learning opportunity for our students.
