Pay the structural engineering fee to do the job right the first time. If a mistake is made, you will pay heavily for the consequences, financially and structurally. Structural drawings can get spendy, so if it’s not essential, you may want to skip.Įven in the unlikely scenario that your city does not require a building permit, you should always have a structural engineer verify if the wall is weight-bearing and part of the structural system. Once they have analyzed the project and collected necessary information from the site, they will return to the office to generate a drawing with structural details. An engineer will still need to come on site and perform the inspection. In this case, a structural drawing may be needed. Assumed composite action with a single layer of 24' on-center span-rated, glue-nailed floor panels for deflection only. Clear distance between supports Minimum bearing length of 1¾' end (no web stiffeners) and 3½' intermediate. Note-If your wall is non load bearing, a letter from an engineer should be enough to fulfill the building department’s needs.Ĭ) Structural drawing- There are some instances when an inspection & scope of work simply aren’t enough for a building department to release a permit. More restrictive of simple or continuous span. Keep in mind, this scope is typically geared towards experienced contractors it could look like Latin to a beginner or someone not in the field. This scope of work is essentially an instruction sheet a contractor can use to perform the work and a building department can use to understand and approve the work. In this case, building department’s may request a scope of work to remove the wall, install temporary supports and detail what the replacement system must be. Sometimes this is enough to pull a building permit.ī) Scope of work- Sometimes a letter stating whether a wall is load bearing is not enough to pull a building permit. Typically, a follow up signed/stamped letter will be generated stating what was observed on site. By using these tables you can find the most optimal cross-sections for the structures. The tables below describe the most common measurements according to local requirements for different Kerto LVL structures in floors, roofs and walls. They could affirm to the homeowner whether or not the wall is load bearing. Span tables for Kerto® LVL beams, panels, studs and I-joists help designers work faster and more efficiently. ![]() ![]() would come on site and inspect the wall in question. Possible requirements from city building department-Ī) Structural engineer inspection: This typically means that a licensed P.E. If you know ahead of time that your city’s building department requires a structural engineer’s stamp of approval on your plans, you may be able to keep things moving. Common materials for replacing a load-bearing wall with a beam & column system are joist hangers, joist hanger nails, LVL’s (engineered beams), 8d framing nails, header material (2×4’s), 16d framing nails, and construction adhesive. Most structural engineers are booked out at least a few weeks. It’s a good idea to call your building department ahead of time in order to prevent delays in the project. In order to pull building permits for your wall project, you may be required to hire a structural engineer to perform an inspection.
