Shear Wall

Shear Wall

During a remodeling project on a military base two existing joining building walls were removed.  This caused the building to shift.  We were contracted by the General Contractor (GC) to reinforce/replace sections of the wall with a new Hybrid Steel Frame / Ordinary reinforced concrete shear wall system.    GC on the project presented to us the military’s plans.  We reviewed the plans and offered changes to help accommodate with the projects current level of completion.  Not interfering with current work and to spend as little time and money on the modification.  Once all plans were agreed upon, our portion of the remodel only lasted 17 days.

North Shear Wall

North wall was formed between (2) bays with Steel Frame reinforcement consisting of channel iron to contain the ends of the concrete and a horizontal wide flange beam to create a window to accommodate for the existing overhead duct work.   The traditional method of wood form work, steal snap ties and reinforcing bars were used when placing the concrete.

South shear Wall

South wall was also formed between (2) bays with Steel Frame reinforcement consisting of channel iron and wide flange beam.  Additionally because of the limited space between the walls we used steel plate backing and coil rods with the traditional wood form work on the front.


Both walls were poured with a 4350 psi minimum concrete.  On site mixing, precise water control and vibrators placed along the wall form work during pumping insured that concrete flowed and distributed evenly.  Each wall was pumped on the weekend and was completed in less than 8 hours each.

Retro-fitted Truss

The purpose of this truss is to provide a 60 foot wide opening to move stainless steel tubing from the forming bay to the finishing bay of the manufacturing plant.

The truss supports three columns of a building and crane way live loads.

Sam Vacek PE designed the construction of the truss and we designed the method of installation.

Sam envisioned in place welding as the primary method of installation.

We designed and built the truss as 100% bolt-up at ground level,  then lifted completed truss to installation height.

This is a typical example of our ability to provide solutions for improving the outcome of non-forgiving scopes of work.

Custom Drain Installation

From design to reality...

Here is an example of a customer asking us to cut into an existing concrete floor.  They gave us the desired lay out and suggested a pre-sloped fabricated drain system.

Our job was to make it happen.  From cutting the floor, digging the trench, installing the drain and refinishing the floor.  All within a budget they could afford.

Work was done on weekends and during normal business hours.  Safety was key!
