We bring extensive experience and professionalism to every project and customize our support to your individual priorities and concerns.

Areas of Practice

Construction Engineering Design
The world of construction is ever evolving, and we’re not just talking about BIM trends. With the consistent introduction of enhanced construction products and the growing diversity of project delivery strategies, the opportunity for economical engineering grows, but so does the need for specialized knowledge with a quick turnaround. That’s where we come in.

From delegated design items to construction shoring – we are specialty engineers, successfully completing over 150 construction engineering projects in our first 2.5 years of operation.

Our experience includes temporary shoring and bracing, sheet piling design, structural analysis for temporary loading from construction equipment, and delegated design submittals for cold formed metal framing, structural steel connections, and steel stairs and railings.

Structural Design Engineering
Clarifying a client’s priorities is in itself a creative practice. It requires finesse, strategic thinking, and in many ways, empathy. At the end of the day, construction projects and their worth are profoundly personal to each stakeholder.

That’s why our first step on every project is a dive into understanding your priorities and ambitions – whether you are an owner, contractor, or fellow design professional – resulting in a more efficient delivery of effective solutions from day one through construction.

Our experience with new construction, restoration, and modification/expansion projects covers all major commercial building types as well as a variety of residential building styles. Whether you are working with wood framing, structural steel, reinforced masonry and concrete, or prestressed concrete, we have designed it.

Structural Assessment
Change happens – sometimes we plan it and sometimes it surprises us. From structures that need to adapt to meet the changing needs of their occupants to structural failure caused by extreme weather events, we offer a professional level of care that you can rely on for your commercial projects.

We perform structural analysis, render opinions, and collaborate with the broader design team to develop relevant recommendations – providing the clarity you need to get your building back to peak performance.

Our experience includes facility assessment, failure analysis and repair recommendations, damage assessment reports, change of use load rating reviews, structural analysis for support of mechanical and electrical system upgrades, and design of necessary repairs or reinforcement.
