How an Expertly Crafted Engineer Letter Unlocked the Final Step in Home Construction
When it comes to constructing a new single-family residence, the journey from the first scoop of dirt to obtaining the all-important Certificate of Occupancy is filled with complexities and hurdles. Recently, in Lago Vista, Texas, a situation unfolded where a contractor was grappling with a permitting hold that was hindering them from crossing the final stretch. The obstacle? A retaining wall that needed engineering approval. This retaining wall was not originally designed or planned, but was added as a decorative feature to cover a cut of the rocky terrain.
This type of Stone wall construction, as utilized in this Lago Vista, Texas project, involves multiple components for stability and durability. It starts with a reinforced concrete footing as the base, followed by layers of solid stone that are grouted together. This structure is further reinforced with steel stone locks, backed by a moisture barrier, and includes a gravel backfill and weep holes for drainage.
The Challenge
The wall was assembled with layers of solid stone, at a slight angle. However, local Building Code demanded that such structures receive an engineering certification to ensure their safety and compliance with the existing guidelines. With the permitting hold in place, the coveted Certificate of Occupancy was just out of reach for the homeowner.
The Solution: Retaining Wall Engineer Letter
Enter Oasis Engineering, our firm specializing in structural assessments and engineering certifications. We conducted a thorough analysis, focusing on the as-built conditions, construction methods, and soil conditions adjacent to the wall. All these elements are crucial for ensuring the structural integrity of the wall and ultimately, the safety of the home.
The wall was built against a rock based cut, which means minimal active soil pressure. This type of construction is common in the Austin and Lago Vista areas, given the natural terrain. To move forward, what was needed was a foundation engineer letter to confirm that the wall met all engineering standards, codes, and practices.
The Outcome
Armed with our detailed engineering certification, the homeowner could successfully get the permitting hold released. The joy of finally receiving their Certificate of Occupancy was immense, and it was a win-win situation for all parties involved.
