"Excellent experience again with Alpha Structural. Charlie Rosenkranz came to see the 3-story apartment building in West Hollywood. We discussed what the soft story retrofit plans will likely include. He's knowledgeable and experienced. We appreciated his professional no-pressure approach and answering our questions. Alpha performed an exploratory investigation of the support structure, as architectural plans were not available. They engineered the plans with city approval. They then consulted with us and provided the approved THP (Tenant Habitability Plan) paperwork. Production Manager Dave Schlaich and Job Supervisor Seth Price met me before construction. Dave went over the approved plans and explained the work that would be performed, and the purpose. They both answered all my questions. Lawrence and Antonio were the main work team. They were very pleasant and answered all our questions. Both had great explanations with Lawrence being very detailed. Seth provided timely progress reports by phone and text. He answered all questions, and provided contacts for automatic shut-off gas valves and stucco work. Despite Covid-19, they scheduled and passed inspections, and completed the work in under a month. We've seen projects by other companies stuck in limbo for months with no progress, so we chose Alpha to avoid complications. They removed all debris, and left the property clean. The tenants and neighbors had no complaints. Daniel Aparicio also explained various issues. Communication with everyone, including the office staff, was excellent. We're very pleased with this experience."

"I had the pleasure of working with Aws on a recent project and was thoroughly impressed by his professionalism and efficiency. He delivered a clean, straightforward structural design that met all the necessary requirements without unnecessary complexity. Aws was fast, reliable, and highly communicative throughout the process, making coordination smooth and strass-free. On top of that, the pricing was very reasonable. I highly recommend Aws and his firm for any structural engineering needs. They offer a great combination of expertise, responsiveness, and value."

"I hired CCD to help me permit a structure that I built (Rooftop Deck) and then had a neighbor complain about, leading to lots of trouble and compliance issues. After getting some quotes (that were often 2-3 times what I ended up paying) I found CCD. Mike told me they have never failed to permit a single unpermitted structure... and 12 months later mine is another one of their success stories. I had them draw up the plans and the city approved his blueprints without a single correction which I understand is rare in Santa Monica. I am very satisfied with everything CCD did for me & would not hesitate to hire them again."

"I contacted Geotechnical, Inc. over the phone and immediately knew that they are the right team to help me complete my projects. My main contact at Geotechnical, Inc. was Engineer Mr. Nadim S. who was very knowledgeable, subject matter expert, professional, and best off all had great communication at all stages of the project status. Mr. Nadim, is also credit to saving me tons of rework, he made sure that the engineering team I hired to do the architecture/structural design adhered to sound engineering principles and safety standards. Geotechnical, Inc. saved me tons of rework and ultimatly money. I would definitely work with Geotechnical, Inc. in the future and highly recommend them to others. I do not usually leave reviews however Geotechnical, Inc. has earned my respect and deserve the feedback."

"Our home had an outdated layout. All the different living spaces were closed off by walls. We wanted an open concept from the living room to dining room to kitchen. After interviewing several contractors, we felt that Pacificland Constructors better understood our needs and their price fit our budget.
Martin and his crew at Pacificland Constructors came in and did an outstanding job! The
first thing that they did was place up plastic ?walls? to block off the dust to the rest of
the home. They also laid down two layers of thick cardboard paper on the ground too
prevent the existing floor from being damaged. After the prep work, they quickly
removed the two non-load bearing walls. Pacificland hired an engineer to do the
structural design of the load bearing beam that would be used to support the roof and ceiling in lieu of the existing wall. A temporary wood wall was constructed to support
the existing ceiling and roof while the crew removed the existing walls. Next they
installed the structural beams, wood posts, and the metal connectors. After the beams
were set in place, the temporary wall was removed.
Once the flush ceiling beams were installed, came all the easy finishing work. The crew
moved all the existing electrical outlets and switches to adjacent walls, installed the
drywall and did the rough taping, and closed up an existing window. Pacificland
Constructors was done in 5 days and did a great job cleaning up the job site. Whenever I
had a question all I had to do was either call, text, or email him. He was very accessibly
and helped answer all my questions during the construction process. I would definitely
recommend and use him again for future projects.

"Our Architect directed us to this company for structural drawings and plans. I have to say, in the entire process of purchasing a home, coming up with architectural plans for a remodel and then translating into structural drawings, Design Everest was head and shoulders above all the parties involved. The PM (Nanak) was prompt, on top of the details and very responsive. He proactively flagged any delays and hold up in schedule and followed up with updates on status and any feedback from the city or engineer throughout the process. I highly recommend them for their professionalism, promptness and efficiency."

"We had already had paid an architect and structural engineer to create blueprints.  My plan was to contact 4 contractors to submit bids for the job.  I found Goodfellas through Angie's List and they had a ton of great reviews, so I went to their website and requested a quote.  In less than 24 hours they contacted me and we scheduled an appointment for the next day.  I met with Danny and showed him the blueprints, and we talked about some other details that we wanted to see from the project.  Danny was very patient and took a lot of time listening to my wants/needs, but also gave some great suggestions on how we could improve the look and feel of the home.  After about an hour and a half, Danny provided me with a detailed quote and was on his way. 
My wife and I continued to interview other contractors, but finally settled on Danny and his team.  Once I let Danny know we were going to go with Goodfellas, he scheduled another appointment with us to go through the contract.  This meeting was substantially longer than the first, but only because Danny is so detail oriented that he wanted to make sure that every possible piece of the project was covered in the contract.  After settling all the details of the contract, we discussed start dates.  Initially, Danny had promised to start about a week after the meeting, however, he called me later that night and said that they could start in a couple days. 
Work started on 11/30/15.  Danny was on-site the first day with his crew walking them through the various aspects of the project.  I was not home at the time to meet all of them, but did get a chance to meet the Foreman, Rudy.  Rudy and his team stayed well past sunset to get some concrete demo work done and were back bright and early the next morning to finish it up.  By the end of the second day they had removed all the old concrete and had dug up the area where the new foundation will eventually be laid.  I am very curious about how this process works and Rudy has been more than willing to take a few minutes to explain things to me. 
The project is still on going, but I know Danny, Rudy and their team are going  to continue to do great work.

Structural Engineering questions, answered by experts

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

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.

Indications include cracks in walls, uneven floors, and sticking doors or windows that suggest foundation movements.
