Single-Family Home (Barndominium) Foundation Design (Kingsbury, TX - Guadalupe County)
Budget: $750 – $1,500 USD
Project Overview:
We are seeking a licensed structural engineer to provide a sealed foundation design for a new ~5,759 sq. ft. steel-frame barndominium residence located in Hallsville, Texas. The site contains expansive clay soil, and the foundation design must account for soil movement, slab stability, and steel anchoring.
The home will be constructed using a pre-engineered metal building (PEMB) system, with approximately 3,000 sq. ft. of conditioned space, a 1,240 sq. ft. garage/shop, 538 sq. ft. front porch, 501 sq. ft. rear porch, and a 480 sq. ft. breezeway.

Architectural Summary:
Total Area Under Roof: ~5,759 sq. ft.
Living Space (Heated/Cooled): 3,000 sq. ft.
Garage/Shop: 1,240 sq. ft.
Breezeway: 480 sq. ft.
Front Porch: 538 sq. ft.
Back Porch: 501 sq. ft.
Ceiling Heights: 10' 1-1/8" throughout most living areas
Steel Frame Columns: 6"x6" throughout porches and breezeway
Foundation: Concrete slab (anticipated to be polished in conditioned areas)
Roof Pitch: 5:12
Special Notes: Showers are recessed into slab; French drain system is integrated into multiple slab areas (garage, utility, etc.)
---
Site Conditions:
Soil Type: Expansive clay (soil report to be provided or arranged upon request)
Topography: Relatively flat
Existing Structures: One existing structure to be demolished after new home is built, one shop to remain
Drainage Plan: French drains planned around slab perimeter and garage interior
Utilities: City water; on-site septic system; propane planned
Location: Kingsbury, TX (Guadalupe County)
---
Scope of Work:
The selected engineer will:
1. Design a foundation system appropriate for PEMB construction and expansive clay soil:
Recommend and design either a post-tension slab, pier-and-beam with void boxes, or another proven system.
Include reinforcement details to mitigate soil movement.
Account for anchoring requirements for pre-engineered steel structure.
2. Coordinate with the building supplier to align anchor bolt layout and foundation embed dimensions with steel frame specs.
3. Include load-bearing calculations and recommendations for porch columns, garage loads, and breezeway connections.
4. Incorporate drainage and elevation considerations into the foundation design to maintain slab integrity (French drains, floor drains, garage channel drain).
5. Deliver sealed foundation plans suitable for submission to the city/county and for use by the general contractor.
---
Deliverables Required:
Stamped foundation plan (PDF + CAD if available)
Anchor bolt layout (based on PEMB supplier info)
Structural notes and general specifications
Any special instructions for site prep or drainage
Optional: On-site visit if needed
---
Timeline:
Start Date: As soon as possible
Design Completion Desired: Within 3–4 weeks of engagement
Construction Target: 3-4 months
---
Preferred Qualifications:
Licensed Professional Engineer (PE) in Texas
Experience with barndominium / PEMB foundations on expansive soils
Familiarity with ICC/TDI codes and post-tension or pier designs
Residential foundation design portfolio (samples may be requested)
---
Proposal Submission Request:
Please include:
Fee estimate (lump sum preferred)
Timeline for deliverables
Project references (esp. with similar soil and PEMB work)
Any preliminary questions or info needed to get started
