J2.26 Engineering provides structural engineering inspection, design, and advice. We pride ourselves in providing these services with a personal manner for a reasonable cost. J2.26 can provide consultations in new build construction projects, remodels to homes, and Real Estate transactions.
"Unfortunately, our experience with Dan was about as bad as it could be. We were given a timeline of 5 weeks in mid February and, after months of ignored emails, finally received drawings in mid-June, 17 weeks later. Once submitted for permitting, the county realized that the snow load information was incorrect and rejected the plans. Frustrating to say the least. In discussing the requisite changes over the phone, Dan seemed unaware of fairly standard industry terms in residential construction (rake wall, difference between ceiling joist and roof rafter, cut roof vs truss, etc) which made us uncomfortable, to say the least. Keep in mind, this is after months of radio silence and considering we'd have to start from scratch with another engineer. Things were discussed three, four times and necessary changes still not made. Fortunately we work with our building department a lot, and these can be addressed in the field. I understand that delays happen. I understand that things can get complicated, often quickly. That said, I expect a level of professionalism, communication, and competence when paying someone for their service. You're a smart consumer and will do as you wish, but we will never, under any circumstance, be using Dan and J2.26 Engineering ever again."

"Wow. I am thoroughly impressed with Justin and AE Leuken engineers! While other Structural engineers demanded site visits and where going to take weeks to design and approve an Egress window well for a finished basement, Justin jumped all over my requests and had everything completed in 3 Days!!! He was VERY easy to work with, communicated efficiently via text & cell, and even worked on the project at night and early in the morning. Justin was also very privy to the building codes at PPRBD, which many local Structural Engineers were not. Definitely contact Justin and AE Leuken Engineers if you want to get the job done right and quickly!"

FAQs for structural engineering projects in Thornton, CO
No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.
Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.
The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:
Do you have experience working in my specific area?
Do you have professional indemnity insurance?
What will your structural report cover?
Do you charge a flat fee for a structural report or by the hour?
How long have you been in business?
Do you have a list of customer references?
Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.
Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.
