Improving the quality of life through a soundly built structured environment


Commercial tenant improvements for medical, dental, and veterinary structures require engineering expertise, as well as an understanding of specific medical equipment and facility needs and processes. DEI has specialized expertise in evaluating vibration damping for these sophisticated tools.

Clients call on DEI to analyze structures to accommodate potential tenant improvements. We help solve space planning dilemmas by evaluating options and working in partnership to determine the ideal structural solution. Most often, we assess the current capacity and the proposed demand and reinforce the building accordingly.


DEI performs cantilever and tieback soldier pile wall design for steel contractors, architects, and subcontractors. Our scope includes the design of the piles, embedment depths, and tieback anchors, along with full-scale design drawings for pile elevations, layout, and pile schedules.


DEI’s portfolio for auto dealerships has expanded over the past 20 years. We create solutions for signage, brand-specific entry vestibules, new mezzanines inside existing facilities, and other elements unique to dealerships. The open showroom layout is ideal for customers and creates a spacious environment to showcase the vehicles.

The service centers are another integral area of a dealership. We accommodate the engineering for the service centers with minimal columns, large overhead doors, vehicle lifts, mechanical equipment supports, and parts storage.


DEI services a range of multi-family housing types, including apartments, condominiums, assisted living, senior housing, and micro-housing structures. We provide tenant improvements, full structural design, detailing that aligns with project pro forma and customized engineering solutions.

Our cost-effective designs focus on sound structural solutions that allow builders to spend more money on finishes and amenities that attract tenants. DEI is committed to sustainable design and utilizes the latest BuiltGreen, LEED, and Advanced Wood Framing design requirements.


Single family residences often require special framing and detailing for new construction, renovations, and additions. DEI creates unique detailing for high-end custom homes, single-family developments, and townhomes.

From small reports for minor additions to complete drawing packages for new homes, DEI assists clients on projects of all sizes and scopes. Clients benefit from our project managers who offer hands-on service and full CAD capabilities while prioritizing schedule, budget, and constructability requirements.


DEI provides engineering services from pre-design through construction support for new construction, building renovations/additions, and tenant improvements. We are known for strong coordination with the entire design team, collaborative design decisions, and a proactive approach to addressing project requirements.


Whether we are working in partnership with a developer, architect, or contractor, DEI collaborates to create solutions that meet the goals and vision for each project. We create structural systems that balance the unique characteristics of a project with the budget and design parameters of our clients – always adapting our techniques to ensure project success.


DEI offers engineering for unique structures that others in the industry choose to not take on. From working with precast concrete fabricators to MEP design build contractors, our engineers also provide engineering solutions for unforeseen site conditions. Dibble Engineers offers seismic design studies and new or retrofit waterfront dock structures.


DEI offers reliable structural services and quick responses for on-call needs. When municipalities lack the staff to keep up with permit reviews, DEI serves as the agency’s representative, reviewing structural plans for large remodels, seismic retrofits, and smaller tenant improvements. Municipalities trust our opinions and often select us based on our understanding of local codes, industry standards and regulations, and our reputation for integrity, responsiveness, and quality workmanship.
