SW Portland Deck Remodel Project
In this project in Southwest Portland, our clients had a very dangerous, 50-year-old deck with quite a few structural, safety, and environmental protection challenges. It was a safety hazard for anyone walking on it due to the many rotted holes and broken boards, as well as failing railings. The deck was approximately 600 sq ft and 75 feet long.
Part of the deck ran very close to the house, as well as the tree protection fence we had installed as per city code. There was also a large tree within 4 feet of the deck perimeter, which required us to collaborate closely with the Multnomah County planning and zoning department, our architect, structural engineer, and our Oregon state-certified arborist. Coordinating between these stakeholders ensured we fulfilled Multnomah County’s environmental requirements.
We very carefully deconstructed the deck beams and posts to save the tree protection fence on one side and prevent damage to the house and windows on the other side.
Navigating Tree Protection and Structural Constraints
Once we had ensured that the new footing placement would not damage or destroy any critical roots that could cause the tree to die and fall on the house, we began to build the new 240 sq ft deck. In order to avoid the critical root and save the tree, we had to change the new footing placement and reduce the number of footings from 3 to 2 because of the presence of a critical root. This required us to re-engineer a much larger and longer beam than previously used.
Deck Materials Used
Installing a 1,400 lb Structural Beam
The project had some additional fun and challenging structural issues with a 26' long, approximately 1,400 lb beam that had to be hand-carried by six craftsmen 200 ft and down a 45-degree stairway for installation. Once the beam had been moved into position, the installation required extreme precision, as there was only approximately 5 inches of wiggle room.
We had to lift the beam onto the new posts without hitting the original existing post next to it that held up the roof overhead. We flattened the ground and installed a thick plywood base to be able to use a material lift, then had six craftsmen carefully and safely guide it into position.
The Result: A Safer Deck with Long-Term Durability
Our clients now have a much safer and more durable deck that meets current code requirements while working within the environmental constraints of the site. By carefully coordinating with all parties involved and adjusting the structural design to protect the tree, we were able to deliver a functional outdoor space without compromising the surrounding environment.
The new deck provides a solid, low-maintenance surface with improved safety and reliability, giving our clients peace of mind and a space they can confidently use and enjoy for years to come!
