Enriching the construction experience through proactive safety and innovative solutions that creates trust with relentless quality.


In 1981, SDB Contracting Services landed a small office renovation job for Motorola, Inc. Throughout the renovation, SDB recognized the intensive construction requirements of this market type and focused their resources on the cleanroom manufacturing environment. SDB remains committed to the same clients they built partnerships with early on, as well as many new clients. This experience in the high-tech industry, where safety is paramount, SDB built a stellar reputation in mission-critical, occupied environments.

SDB has been recognized as The Valley’s Most Recognized Cleanroom Contractor, five years in a row (Ranking Arizona Business Magazine) working for Motorola, STMicroelectronics, On-Semiconductor, Rodel Corporation and the world’s largest chip manufacturer. SDB performs projects ranging new fabrication facilities such as Motorola’s MOS 21M class 10 cleanroom ($80M , 40,000 SF) to modest door hardware repairs.

Today, SDB’s general contracting and design build clients include healthcare, higher ed, airports, municipalities, and general commercial projects. In addition, SDB self-performs a variety of services and prides itself on the results achieved for its clients. SDB proactively identifies solutions and makes the job of the facility or building owner easier.

Barbara Dupuis
Daifuku American Corporation, Arizona
Safety Coordinator

I observed SDB doing a great job overall, working hard at getting the job done and doing it safely staying aware of their surroundings while working in tight areas, keeping up on their housekeeping and getting their trash removed from the building as quickly as possible. Also communicating with other trades working in the area. GREAT JOB!

I would like to take a moment to express my appreciation to SDB for their quick response to the city water main break at the Community Services Building…went above and beyond that day in restoring water to the building…they are very dedicated workers and truly appreciate their effort.

Michaela Chelini
City of Mesa
Project Manager

SDB worked well with the City throughout change order requests. They were able to negotiate the price and worked as a team with the City to accomplish the additional client department requests. We really think they performed well as the JOC partner and treated this project as a team effort.

Brad Reed

SDB has great Project Managers and Supervisors. They are hands-on Supervisors. SDB’s subcontractors are the best. They are very park friendly and put our customers first. Their work is top rated!

Telma Bearden
Central Arizona Project
Senior Contracting Officer

The CAP team enjoyed working with SDB and Rosendin on this project, they were easy to work with, did a nice job, and finished on time. They had a challenging schedule to meet when the project started construction due to half plant outage availability on the pumping units, but they managed to finish on time and delivered great results. We look forward to working with them again in the near future, it is nice to know that we have a good partner in SDB and Rosendin for the CBM project.

Shabretta Jones
Parkland Health and Hospital System
Offsite Maintenance Manager

I am so very thankful for SDB. I needed to get a clinic open one day after it flooded and SDB fulfilled the job without hesitation. During that urgent time, I didn’t need a “NO” and SDB was able to make my life so much easier.

SDB’s safety philosophy is to strive for an injury-free environment by having employees enroll in safety training programs and commit to jobsite compliance and awareness.

SDB’s commitment to safety is the cornerstone of all that we do as contracting service providers. We are committed to the safety of each employee and client. This commitment is demonstrated by employing a Risk Management Director and a dedicated Safety Department which is responsible for safety compliance and training. This team is the first to arrive, meet with a client, and the first on a project site to develop a site-specific plan. Whether you are in need of contracting services in Texas, Oregon, or Arizona, we offer this same safety plan.

The objective of our safety team is to advise management and supervisory personnel on safe work practices, supply information required to comply with the company’s safety program and OSHA regulations and to assure that records are maintained and submitted as required.

Employees with occupational exposure are trained in OSHA 10 and 30-hour courses. The Safety Department is run by the Safety Director and employs field supervisors. At each jobsite, a Project Supervisor trained in OSHA 30 monitors for job safety. It is their role to oversee daily on-site working practices, maintain quality and safety compliance, and coach employees to avoid accidents or hazards. Safety officials monitor construction sites to observe working conditions and assure safety practices are being used. Currently, SDB maintains an exceptional Experience Modification Rate (EMR) of .62.
