✅ As-Built Foundation Certification for Pergola — McKinney, TX

Need an Engineering Letter for Your Pergola Foundation?
In Texas, especially in growing communities like McKinney, many homeowners run into permit issues after completing work without inspections. If your contractor didn’t have a license or missed in-progress inspections during construction, the City may now require an As-Built Foundation Certification from a licensed Professional Engineer (PE).

That’s where Oasis Engineering can help.

We provide fast, reliable foundation engineering letters for residential accessory structures like pergolas, patios, and decks — helping homeowners meet permit requirements and avoid costly delays.

🏡 Project Example: Pergola Foundation Review — McKinney, TX

In this McKinney project, a pergola was installed on an existing concrete patio without prior foundation inspections. The homeowner learned the City required:

✅ A certified engineering letter confirming the foundation’s adequacy.
✅ A site-specific evaluation by a Texas-licensed Professional Engineer.
✅ Documentation to satisfy permit and inspection requirements.

Our client faced an all-too-common situation:

• The original contractor wasn’t licensed.
• No inspections were done during construction.
• The City halted final approval until an engineer signed off.

📏 Our Engineering Solution

Oasis Engineering provided:

• Non-Destructive Site Review
  Our team inspected the property, reviewed construction details, and evaluated the existing concrete slab for structural integrity.
• Review of Slabs Specs
  ➤ Concrete slab thickness: ~5 inches
  ➤ Rebar size: 3/8” (#3)
  ➤ Rebar spacing: 14–16 inches on center
  ➤ Concrete strength: 3,500 psi
• Foundation Certification Letter
  Based on the site review and available documentation of the slab details, Oasis Engineering issued a sealed, Texas PE-certified letter confirming the foundation’s adequacy for supporting the residential light open pergola.
