Structural Work in Pasadena
Shoring, beams and posts for opening a Pasadena wall to the yard, with ember-resistant details where a lot is mapped, by Palmcrest Contractors.
"How does the upstairs stay put while the wall is gone?" If that comes up when we first walk a Pasadena house with rooms over the wall, the answer is temporary shoring: short walls of posts and plates set on each side, carrying the floor until the new beam is in. That sequence is planned before demolition. Parts of Pasadena are mapped for fire hazard, so the outdoor face of a new opening may need ember-resistant details as well.
Holding the load while the wall is out
Before a stud is cut, temporary walls rise on each side of the opening. Each one has a top plate snug under the joists, posts at close spacing and a bottom plate spread across the floor so the load does not punch through. On a raised floor, the shoring may continue down into the crawlspace to reach the ground. Once the new beam, posts and connectors are in and inspected, the temporary walls come out in the order the engineer sets, leaving the new beam and its posts to carry the floor.
The outside face of the opening
A new opening onto a patio changes the outside wall as much as the inside one. Where a Pasadena lot is mapped for fire hazard, the review can reach the glazing, the vents in nearby eaves and the cladding that wraps the new header. Exposed beam ends and post bases are detailed so embers have no gap to lodge in. On an unmapped lot the same opening is drawn for weather, with flashing over the head and a sill pan below the door. Both sets of sheets, exterior and structural, travel together through plan check at the City of Pasadena.
Structural Work in Pasadena: what people ask
Look at what sits on top of it. Joists or rafters resting on the wall, a beam end, or a second-story wall stacked above are all signs it carries weight. We check from the attic or through a small ceiling cut, and the engineer confirms before any framing comes out.
When the span is modest, yes. The beam has to fit within the depth of the joists it picks up, and those joists are hung from its sides with metal hangers. A long opening may need more depth than the ceiling holds, and then a shallow soffit finishes the part that drops.
A California licensed engineer, civil or structural, sizes the beam, posts, footings and shoring sequence, then stamps the calculations. Those sheets join the permit application in Pasadena. If the open wall shows something the plans did not expect, work on that part pauses until the engineer revises the detail.
