Structural Work in Pasadena
Pasadena beam work sized for stiffness so upstairs doors keep closing, plus footings, ember-resistant vents and bolting along the load path.
Upstairs doors tell the truth about a beam. Take a bearing wall out of a Pasadena floor plan and the joists above it hang from new lumber or steel, and if that member flexes too far the bedroom doors start to rub their frames and plaster seams open. We ask the engineer to size for stiffness as well as strength, so the second floor stays put while people walk, sleep and carry laundry across it.
Stiffness you can live with
A beam can be strong enough to carry its load and still bend enough to notice. Engineers cap that bending, called deflection, as a fraction of the span, and a tighter cap means a deeper or heavier member. Over a wide opening we tend to ask for the tighter figure, since tile and plaster above crack at smaller movements than carpet and drywall. The posts at each end stand on footings sized for their new point loads, and the beam is set level and snug before any wall below it is cut away.
Footings, vents and the review
Where those posts reach the crawlspace, new footings are poured beside the old foundation, and the openings cut to get there are a chance to replace tired foundation vents. A lot in the parts of Pasadena that fall inside mapped fire hazard zones may face ember-resistance rules, and vents with fine metal mesh meet them while letting the space breathe. Pasadena's building and safety staff review the beam calculations, footing details and vent changes as one package, and each footing is inspected before concrete goes in.

Structural Work in Pasadena: questions
The two do separate jobs, so a house can need one, both or neither. Bolts pin the wood sill to the concrete, and plywood on the cripple walls keeps those short walls from leaning over in a quake. Cripple walls do not exist under a slab house. Our visit records which pieces exist and which are absent, and the scope names only the absent ones.
For a beam that opens a floor plan, a structural engineer prepares the calculations and details, and we coordinate that work with our scope. Plain bolting can follow standard retrofit sheets. In either case the set goes to Pasadena's building and safety staff, and work begins after the permit issues.
Where the posts and girder bear. A post perched on a loose block, or a girder splice with nothing under it, can explain a dip in the floor above, and it matters before beam work adds load. After that we check the sill, the anchor bolts, the cripple walls and the vents, and you get the findings and scope in writing.
