The Project Goal
The residential client was planning a custom barndominium in Grimes, Iowa. The project required more than a basic layout because the structure combined residential living areas, garage or large-span areas, porches, truss framing, post-supported elements, and lateral-force-resisting systems within one coordinated building package.
For a custom structure like this, the main engineering goal was to translate the project concept into structural construction documents that could be coordinated by the project team. The plans needed to address how loads would move through the roof, walls, floor framing, columns, slab, and footings while also providing practical construction details for the contractor and related trades.
Why Engineering Was Needed
Barndominiums can involve structural conditions that differ from a conventional framed residence. The design may include large openings, taller wall areas, roof trusses, post-frame components, garage door openings, porches, shear walls, and specialized connectors. Those elements need to work together as a continuous load path.
StructSolve’s role was to provide structural engineering and drawing coordination for the proposed building. The source documents identify design criteria for roof, floor, wall, wind, seismic, and deflection considerations. The plans also reference wind speed, exposure category, roof and floor loads, snow loads, and delegated truss design requirements. Those criteria helped define the structural basis for the drawing package.
StructSolve’s Design Scope
StructSolve developed a structural design package for the barndominium that included general notes, design criteria, foundation information, framing plans, roof bracing, elevations, and construction details. The scope focused on the structural systems needed to support the custom residential structure rather than a general inspection or report.
The foundation plan coordinated slab thicknesses, footing sizes, minimum footing depths, column footing conditions, thickened slab areas under interior walls, vapor barrier and reinforcement notes, and separation between slab areas. The foundation control joint plan provided additional coordination for slab joint placement.
The framing plans addressed the first floor, upper floor, roof-related framing, wall construction, truss bearing, LVL beam locations, headers, column supports, porch framing, lateral bracing, and shear wall requirements. The elevations and details added construction guidance for exterior wall framing, openings, post bases, hold-downs, top plate splices, truss bearing, diaphragm nailing, and other connection conditions.
Key Structural Design Considerations
A major part of the design package was coordination of the building’s lateral system. The plans include shear wall notes, continuous structural sheathing requirements, hold-downs, anchor bolts, roof bracing, cross-bracing, drag strut references, and diaphragm boundary details. These elements are important because a custom barndominium must transfer wind and roof forces through the framing and into the foundation in a coordinated way.
Wind-load support was also part of the source package. The wind calculation material addressed roof uplift, lateral wind pressures, roof diaphragm forces, shear wall forces, overturning checks, and post-base bracket capacity references. The design criteria identified wind speed and exposure assumptions, and the plans incorporated related bracing and connection requirements. The public case study does not need to reproduce the calculation tables, but those calculations helped support the structural coordination shown in the drawings.
The project also required coordination with delegated truss design. The general notes indicate that truss drawings were to be provided by the truss manufacturer and sealed by an engineer licensed in the project state. StructSolve’s drawings identified truss design loads, truss bearing conditions, bracing requirements, hanger and hurricane tie references, and coordination points where manufacturer-provided truss design would need to align with the structural plans.
Foundation and slab detailing were another important part of the design. The drawings included monolithic slab conditions, reinforced concrete notes, compacted fill requirements, control joints, thickened slab details, porch footing details, garage slab details, and column-base installation details. These details helped coordinate the transition from the building frame into the concrete and footing system.
Construction Documents and Details
The plan set included multiple structural sheets that worked together as a construction-document package. The general notes established applicable codes and design standards, material requirements, load criteria, concrete notes, wood framing notes, truss notes, and foundation requirements. The plan sheets then applied those criteria to the building layout through foundation, control joint, floor framing, upper framing, roof bracing, and elevation drawings.
The detail sheets provided enlarged guidance for items such as slab edges, porch and garage footing conditions, Sturdi-Wall post-base installation, thickened slab areas, top plate splices, truss bearing at wood walls, door opening framing, hold-downs, diaphragm nailing, and endwall truss conditions. These drawings gave the project team a clearer reference for how individual structural components were intended to connect.
Because the source material included plan sheets with title blocks and private information, any public images should be cropped carefully before use. Cropped excerpts of non-identifying structural details, bracing diagrams, or framing-plan areas would be more appropriate than full plan sheets.
Project Outcome
StructSolve’s design package provided structural drawings and wind-load design support for a custom barndominium project in Grimes, Iowa. The deliverables helped organize the foundation, slab, framing, roof bracing, shear wall, and connection information needed by the project team.
The drawings did not by themselves document final construction completion or final approval, so the public outcome should remain cautious. The supported outcome is that the design package gave the residential client and project team coordinated engineering information for planning and construction-document use.
