Design Build Engineering

e3i Engineers’ dedication to design build is an important delivery method that sets us apart from our competitors.

Design build is a popular project delivery method across North America and that has gained traction in New England and the Northeast. Several contractors are employing this model, but few electrical engineering firms have this as one of their primary focuses. While many contractors seek the lowest-cost solutions, design build partnerships foster a higher-level of engineering for a more valuable outcome. Additionally, our positive working relationships with contractors is an asset to our clients. Because we understand the contractor workflow and our place within it, we are able to integrate into their process to make the biggest positive impact and mitigate construction setbacks.

Likewise, we specialize in design assist when design build is not an option. We communicate well across all team members and support the owner’s and contractor’s best interests when decisions are on the table. Our collaborative and proactive mentality fills the gaps to deliver our projects to the client’s satisfaction.

Design Assist Engineering

e3i Engineers provides Design Assist Engineering services, a service method by which a contractor selects an engineering design firm to be their advocate and provide assistance on a particular project.

The Design Assist Engineer (DAE) is retained by the contractor and separate from the engineer of record (EOR). The DAE is an integral and active member of the team and is the installing contractor’s link to the design process. The role of the DAE is to be the representative of the installation contractor throughout the design and construction phases of the project. The DAE’s involvement can be for a single design or construction phase of a project but it is recommended that their involvement begin at the conceptual phase.
