Willis Engineering, Inc. is a structural engineering firm based in Phoenix, Arizona, specializing in structural design and related engineering services for residential, multifamily, and selected commercial building projects. Founded in 2009, the company focuses on practical engineering solutions, project coordination, quality, reliability, and cost-conscious design. Its professional team brings more than 60 years of cumulative structural engineering design experience, according to the company’s official website.

Serving clients across multiple states, Willis Engineering works with homebuilders, architects, contractors, developers, and other construction professionals. Its approach emphasizes coordination between engineering requirements, construction methods, project budgets, and client objectives. By considering these factors throughout the design process, the firm aims to help project teams develop structural solutions that are practical to construct and appropriate for their intended use.

Structural Engineering Services

Willis Engineering provides building structural design services for a range of residential and building projects. Structural design considers the building’s intended use, applicable building codes, gravity loads, environmental loads, and the construction methods available for the project. The objective is to develop a structural system that supports building performance while balancing safety, constructability, and project cost.

The firm’s services also include offsite structural design and support, value engineering reviews, peer reviews, structural observation, warranty support, and forensic analysis. These services can support different stages of a building project, from early planning and design coordination to construction observation and the investigation of structural concerns.

Residential and Multifamily Project Experience

Residential construction is a core focus of Willis Engineering. Its stated project experience includes single-family detached production housing, custom homes, multifamily attached housing, senior and assisted living housing, and additions or remodeling projects.

The company also lists experience with hotels and motels, commercial and military housing, low-rise commercial buildings, retail and storage facilities, and earth-retaining structures. This range of project types allows the firm to work with different project teams and building requirements, depending on the specific scope and location.

For developers and homebuilders, coordinated structural design can help align engineering documents with architectural plans, construction schedules, and the practical needs of the building site. Willis Engineering describes interdisciplinary coordination and communication as important elements of its approach to structural design.

Offsite Structural Design and Support

Offsite structural design and support is another service offered by Willis Engineering. Depending on a project’s needs, this type of service can help construction teams plan and coordinate work associated with offsite capabilities or improve an existing process.

The firm’s service information identifies offsite structural design and support as a distinct offering. Project owners and contractors should contact the company directly to discuss the specific requirements, deliverables, and suitability of this service for their construction plans.

Value Engineering and Peer Reviews

Value engineering reviews consider the relationship between building function, structural requirements, construction methods, and cost. Willis Engineering offers value engineering services intended to help clients evaluate building value and the balance between function and cost.

Peer reviews provide an additional engineering review of structural designs or related documents. Depending on the assignment, a review may help project teams identify questions, evaluate design approaches, and coordinate technical decisions before construction proceeds. The exact scope of a peer review should be agreed upon with the engineering team.

These services can be relevant to architects, developers, builders, and other project stakeholders seeking a coordinated approach to structural planning and design decisions.

Structural Observation and Warranty Support

Willis Engineering provides structural observation services for new residential structures and existing residential structures involved in renovation projects. The company describes observations that may support value engineering, risk management, preparation of as-built drawings, and evaluation of whether construction is proceeding as planned.

Its stated process may include detailed notes, photographs, structural evaluation or analysis where required, written reports, and construction documents. The scope of observation and reporting depends on the specific project and assignment.

The company also offers warranty support services. Its website explains that support can continue after design and construction, with structural observations and forensic analysis used to investigate areas of concern and help determine possible causes and remedies. Builders, homeowners, and contractors can contact the firm to discuss a particular structural issue and the appropriate next steps.

Forensic Structural Analysis

Forensic analysis is among Willis Engineering’s listed services. This work can involve investigating structural conditions, reviewing available project information, and evaluating potential causes of observed building distress or other concerns.

The company identifies forensic analysis as part of its broader structural engineering service offering. Clients should provide project details and relevant documentation when requesting an evaluation so the firm can determine whether the matter falls within its expertise and service scope.

Service Areas and Project Coordination

Willis Engineering’s center of operations is in Phoenix, Arizona. Its official service information lists Arizona, California, Colorado, Nevada, and New Mexico among its licensed states, while Texas is marked as pending on the company’s published services page. Because licensing information can change, clients should confirm current authorization for the state where their project is located before engaging the firm.

The company emphasizes communication, coordination, and timely delivery. Its stated service philosophy prioritizes quality, reliability, integrity, timeliness, and ingenuity. These principles are particularly relevant to projects involving multiple consultants, contractors, and construction stakeholders.
