Typical Structural Repairs Include:
Roof condensation is moisture that develops at the roof ceiling area and is trapped by foil insulation or other types of radiant barriers and, if left untreated, can destroy the entire roof structure. In addition, certian types of tenant operations can exacerbate the problem. Roof condensation damages are commonly seen in industrial tilt-up buildings where a radiant barrier or foil insulation is installed beneath the roof’s frame, trapping the framing bays without proper air ventilation.
We typically remove or vent foil insulation from ceilings in tilt up buildings to prevent corrosion on the framing member hangers. After removing or venting the foil, ledgers are then put up under the existing framing hangers to prevent sagging and add support.
GLB, Purlin and Sub-Purlin Repairs
In some instances, structural framing members are damaged either due to the weight they carry, faulty installations, or exposure to elements. Repairing these damaged members by replacing the member with something similar or adding additional steel of wood members to the existing beam. In the case of GLB repairs, epoxy injection, steel rods, high-strength cable tensioning or steel rod tensioning (we prefer high strength cable in lieu of steel rod tensioning).
Similar to GLB and Sub Purlin Repairs in this situation we’ve used high tension cables to strengthen the bottom cord of the truss where most of the loading occurs. Other repairs include replacing or adding to existing vertical members and repairing the top and bottom cord of the existing truss.
Column Repairs (concrete/ steel/ wood)
Columns can sometimes be damaged due to impact (forklift drivers) or normal deterioration. Repairs may include shoring the beams to relieve the load on the damaged column.
Columns can be fixed either by the replacement of, or adding additional wood/ steel members to the existing column.
Door Opening Repairs with H-Frames
Tenants sometimes make changes to your building without a structural engineer’s approval. When they cut existing concrete walls to make new openings, they fail to strengthen the new opening.
Repairs include the addition of tube or channel steel around the opening and usually vertical members on each side floor to ceiling.
Epoxy Injection (cracks in concrete)
Concrete buildings develop cracks. Concrete cracks because of time, thermal changes and impacts or excessive loading.
Wall and slab cracks that are not sealed properly with epoxy injection over time will expand due to moisture entering the crack and rusting the rebar inside. The rust expands the diameter of the rebar and forces the concrete to crack and/ or spall.
The cracks are injected with high strength epoxy which seals and binds the concrete. Any spalled concrete is repaired by removing any and all damaged concrete rebar and replacing with high strength grout.
The strengthening of non-structural items in a building including all equipment, office furniture, etc.
