"We needed some room additions to our small house in Burien. After speaking with several other architects and seeing how flaky they were right off the bat, we were dreading the whole process. After speaking with Char once we knew we were in good hands. Her communication was perfect. We would have weekly updates to go over the process and discuss any changes or recommendations. We were on a tight budget for the building costs, so when we found a contractor that we enjoyed, they were able to understand and calculate an accurate estimate from her drawings that were within our budget. She was able to get all the permitting for the additions from the City of Burien within 3 weeks with no redactions. We would hire her again, as matter of a fact, we did hire her for another build/design, Immediately after designing the house additions, but we just ran out of money for that build. I even recommended her to several other friends with their builds."

"I used Triple V as the Project Engineer for a garage conversion to single family residence for my son’s family. Vic not only did the engineering for us, he also did the structural drawings we submitted to the county as part of our permit package. He delivered the plans promptly, and worked collaboratively with us to resolve issues we identified and revise the drawings accordingly. The county building department approved the plans and issued the permit. During the project construction Vic patiently responded to questions from us (we’re DIY’ers, not professional builders) and offered/provided certifications to revisions we jointly agreed to. Overall, Triple V provided what was promised at an outstanding value."

"Josh has always been prompt and communicative with every interaction we've had. I initially got in touch with him about new construction design questions, and when we discovered that our current home porch posts had rotted through due to faulty design by the original home designer, Josh jumped into action. He had his engineer and construction crew to our door within 24 hours to take a look and put together a plan. He took my design ideas and brought them to life. He was transparent about all parts of the cost (to include his profit), and gave us to option to lower the cost by hauling away debris and painting the porch (which we were more than willing to do). Any delays with the work were met with a phone call and followup email if he didn't get through to either my husband or I immediately, and the construction crew did very high quality work. We were beyond pleased with his customer service! We will definitely use Revival Home Designs in the future when we decide to build our forever home."

Structural Engineering questions, answered by experts

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.

The standard thickness for an LVL beam is between 1.75 inches and 7 inches. However, you can order LVL beams in non-standard sizes as well. When you work with a contractor, they can source beams that are the appropriate size for your project for you after assessing your blueprints.
