Glu-Lam Wood Pole and Foundation Reinforcement

Solano County, CA

Challenge

Solano County, CA: A carrier’s proposed antenna loading exceeded the existing capacity of the structure and foundation for his site. The existing rectangular wood Glu-Lam pole and foundation required reinforcement to carry the proposed new equipment.


Our Approach

The capacity of the existing wood pole shaft was substantially increased by using steel flat plate reinforcing. The new steel plates were bolted to the wood shaft and anchored to the foundation with new anchor rods. The existing foundation was augmented with a new reinforced concrete mat.

The Results

The structural modification design included bolt-on steel plate shaft reinforcing, cast-in-place steel anchor rods, and a new reinforced concrete mat foundation. With the new modifications installed, the reinforced structure now has sufficient capacity to carry the additional proposed carrier loads with additional reserve structural capacity to spare.
