Structural Engineering reviews in Washington DC

  • The contractor provided the service at the time agreed upon and returned with his report in the timeframe agreed upon. It was easy to set everything up and the results were provided with clear actionable information.

  • David listened to our goals for the project and patiently worked through several options of floor plans until we found the one that worked best for our family. He answered all of our questions, was very responsive, and quickly changed course if we were not totally satisfied. He deigned a beautiful vaulted ceiling with exposed beams in the master bedroom, and added extra touches to make the space really beautiful. He also adjusted the structural designs to ensure we were up to code, as the project uncovered abnormalities in the old house. David allowed us to have complete control of the aesthetic aspects of the design so our home looks and feels just how we envisioned it. He was a tremendous partner in this project, and was completely courteous, professional, and honest.

  • Kamran worked in a visit into an otherwise very busy schedule, which I greatly appreciated. He assessed the issue, looking inside and out, provided a verbal assessment and recommendation, which happened to coincide with the contractor's recommendation. It was a great relief to have the verification of the issue and the best solution.

  • The work seems good so far (installed a sump pump), but our project manager was unprofessional on the most basic things- from coming up with the right design, to informing us when the crew wasn't arriving multiple times until after they were supposed to arrive even though we had taken days off from work, to covering furniture against the massive quantities of dust, to repairing damage the crew made to a door frame, to doing a final inspection... None of that. He seemed mostly interested in getting final payment and moving on. So I unfortunately can't recommend them, even though the crew worked hard and well as far as I can tell. Who wants to deal with a project manager who cares so little about the work and your time?

  • While Kamran himself is a nice man, the services offered by him and his staff are slow, dismissive, incompetent, and unprofessional. I would never use Ohi again. His company is simply not skilled nor responsive enough to manage a single family house renovation. My review below is long. If you are considering using Ohi for your renovation, you have my permission to ask Ohi for my contact information so that I can give you a more detailed review of his services. My project was at 5058 Central Ave SE, WDC I secured the services of Ohi Engineering Group in May 2016 to design drawings so that I could convert the basement into a legally permitted one bedroom accessory dwelling unit per DCRA standards and requirements. It took six months for Ohi to submit the drawings to DCRA. Moreover, the drawings were submitted improperly. Subsequently, it took 11 months from the time I contracted with Ohi until the time I received a building permit, which is three times longer than it should have taken. Below is a timeline outlining how long it took just to get the permit application filed. It does not include the three month delay to get the permit approved due to incompetence on the part of Ohi. 5-19-16 Contract signed with Ohi Engineering 5-31-16 Ohi Engineering conducts site visit and takes measurements 6-28-16 Jasmine sent existing conditions drawings. I respondI that i am away for travel. Jasmine offers to send proposed drawings. 8-31-16 Kamran sends proposed drawings. 9-09-16 Cynthia meets with Kamran at his office to review drawings 9-23-16 Jasmine sends revised drawings 10-1-16 Cynthia sends changes to drawings 10-26-16 Jennifer sends kitchen layout for review. Cynthia approves layout 11-01-16 Cynthia requests MEP drawings for review 11-04-16 Jennifer sends MEP drawings. Cynthia sends changes to MEP drawings 11-14-16 Cynthia meets with Kamran at his office to review drawings 11-28-16 Jasmine submits drawings to DCRA When I did receive drawings from Ohi, there were numerous mistakes - often the same mistakes repeatedly - such as lack of carbon monoxide detectors, missing egress window, inserting HWH tanks when I specified tankless, and inserting ducted HVAC when I specified mini split systems, just to name a few. Jasmine, Kamran Oh's daughter, was extremely rude and disrespectful when I began to ask about the delays. Six weeks after submitting the documents to DCRA I email Ohi requesting that they follow up. I also asked for access to DCRA's ProjectDox system so that I could track the progress of my application process. For weeks Ohi refused to give me access despite my repeated requests and informing them that as the property owner, I am entitled to access. I was told that Jasmine did not want to grant me access because she believed I would not pay them the balance due. In an email dated January 30, Jasmine wrote "If you believe that you are better suited to process your building permit - I will hand over the drawings to you so that you may expedite your own permit (after receiving payment for the remaining balance, minus a small portion for the permitting process)." Finally, on February 2, I was given access to ProjectDox. It was then that I learned through ProjectDox that Ohi applied for a permit but had not uploaded any of the drawings, which meant my application was incomplete, therefore DCRA was not able to process my application. When I informed him of this, he denied it, even though ProjectDox clearly showed this to be true. With drawings now uploaded, I still had to email Ohi repeatedly to ask him to follow up with the appropriate reviewers to move the process forward. Jasmine continuously replied that DCRA has 60 days in which to respond and she was not going to contact them any sooner than that. It was left to me to follow up with each of the reviewers at DCRA to ask them to move their section of the review process forward. I found DCRA to be highly responsive once I reached out to them. ProjectDox is the best thing DCRA could do to benefit project owners. It really made the permitting process transparent and showed the bottlenecks, which in this case were primarily the fault of Ohi. When I DCRA raised an issue about installing sprinklers in the house and requiring 7'6" ceiling height in the basement vs 7', Ohi was unable to research regulations to prove these requirements were not necessary. Had I relied on Ohi, I would have needlessly spent in excess of $60,000 to underpin the footers and install sprinklers, which is not a requirement on a single family home. Their ignorance of the IBC and IRC is inexcusable. I had to do the research and write the responses for Ohi to submit to DCRA. This is not rocket science, Kamran and his team simply do not care to do what they are paid to do. I could literally write pages and pages about the incapability of Ohi. However, I can feel my blood boiling just thinking about their incompetence. Save yourself the trouble and do not use Ohi Engineering Group.

  • J&B has an exceptional level of professionalism. They are responsive, thorough, and meet all deadlines. In addition, very personable! I've used them for personal projects and now they are working with my clients. J&B is reliable and trustworthy as well. I had a carbon monoxide scare in 2016. A contractor told me I needed to replace my boiler for $5000. I consulted with J&B and they discovered blockage in my chimney - it simply needed to be cleaned so the boiler had ventilation. That costs me $350! J&B saved me $4650! I am an interior designer/real estate developer. I now use J&B to inspect existing conditions for all my architectural projects, potential investment properties, and for my client's to assist them in home buying decisions.

  • Kamran Ohi was a pleasure to work with. He examined cracks in our cellar foundation and in an exterior wall just above ground. We were reassured that the house was not in danger, and he recommended a firm to seal the cracks. His expert opinion helped us move forward with appropriate repairs without fear that we were doing too much or too little.
    - LeeAnn H.
  • I hired Kamran Ohi based on reviews on this site. I had a permit for a deck project that was awaiting drawings. From our first meeting to assess the project up to the submission of the drawings was quite professional and relatively smooth. I appreciated the very comprehensive work that was done. It demonstrated the integrity of the work and the respect the company has for the work they do, no matter how small.
    - Gelane W.
  • The work was done on time and on budget by a skilled team. I'm grateful to Lofft for their level of professionalism and care that went into the repairs at my property. I would definitely recommend Lofft and their team to anyone else looking for a competent general contractor in the DC area.

  • The Angie's List representative informed me of the A rated provider, J&B Discovery Inspections, where the rep did a conference call to allow me to speak with Berlin of J&B Discovery Inspections. Berlin went above and beyond, EXCEEDED the needs. He gave me lots of advise and I will follow up on the suggestions he gave me. In terms of public trust and honesty, he outdid himself. I've had numerous occasions with other providers not being honest after purchasing offers online. It seems that what the other companies offer online and what they offer in real life are different and misleading. It was refreshing to speak with someone who was upfront about my needs and what I should do next.
