Cooling Tower Repairs

The Problem
The installed cooling tower, which regulates temperature in the water lines that run to the units, was degrading and becoming less functional. Following the examination of the tower, a quote was given to the owner of about $200,000 to remove and replace the tower. This also required extensive scaffolding and crane use to perform the replacement.
The Solution
Instead of creating a huge financial and logistical burden for the owner, we decided to perform extensive repairs of the cooling tower in phases. This was because the issues with the tower, although difficult, were entirely repairable if done correctly. We decided that the fan shafts and troughs were too rusted to be restored, and the structural seal that held the cooling tower would need to be repaired.
The Outcome
In order to ensure the tower repairs were going to be effective and maintain its integrity, we made sure to replace parts of the tower that could not be salvaged and implement a Sika waterproofing that would prevent any further rust form accumulating and harming the structure. We saved the client $200,000 and a significant amount of time in the process.

Concrete Restoration

The Problem
Cracks in concrete are sometimes caused by improper compaction of the base below the concrete or forgoing the use of control joints. In a parking garage, water brought in by cars can seep through these cracks, rusting the rebar in the concrete which will expand and cause structural issues. The water can also work its’ way into the lighting and electrical systems below or leach minerals out of the concrete and drip onto the cars below.
The Solution
The typical, inexpensive, fast solution to this issue is to use a caulking gun to fill the cracks. While this may work with smaller cracks, it does not for the larger cracks. Therefore, we had a contractor drill ports along the crack line and inject epoxy to structurally bind the two concrete plates together. This also greatly reduces the spread of the cracks in the future.
The Outcome
Where many may decide to use the caulking method as it is the fastest, cheapest option, we provided a more effective, long-term solution with epoxy injection.

Structural Steel Crown

The Problem
The structural steel at the top of this office building, which is prominently known for being the tallest building in San Diego, was beginning to flake and expose the steel to corrosion. Because the steel had been touched up over the years with a variety of materials, the new coating was not adhering. To compound the challenges for the project, the building experiences cool, moist morning air followed by intense heat and sun exposure later in the day. This created a narrow window of opportunity to complete the work.
The Solution
As we were brought in to the project, we decided the best course of action was to focus on a single aspect of the project to generate momentum. We consulted with a coatings expert and they provided materials and installation recommendations so that the steel could be properly prepared and coated against the harsh environment.
The Outcome
We were able to methodically address communications and technical blockades in order to see the project through to completion.
