Our team has almost 60 years of combined field experience from plumbing and pipe fitting, HVAC, electrical, and fire protection. This experience allows our team to engage the design components, the same way sub-contractors in the field would and finding the optimal solutions that maintain design, significantly reduce RFIs and change orders later, enable almost immediate fabrication of trades upon purchase and receive more accurate bids from trades.
Our Team
Clayton Lyons
President
Clayton Lyons is the President of Prefix DfMA, LLC.
Clayton has over 30 years experience in designing and coordinating complex MEP systems. He has developed Prefix’s methodology for high-fidelity modeling. This is combined with an in-depth knowledge of prefabrication techniques to deliver lean design and assembly solutions.
Clayton has worked with high profile owners, design teams and CMs to deliver fabrication-level models early in the process, accelerating project delivery and reducing cost. Clayton has worked with mechanical and plumbing contractors as well, setting up fabrication facilities and improving means and methods of digital design as well as physical assembly processes. Throughout his career, Lyons has modeled and coordinated Billions of dollars of work spanning from iconic fine arts museums to state-of-the-art laboratory projects.
Donal Lyons
Vice President
Donal has worked on numerous projects spanning across all sectors, with a primary focus on healthcare and lab facilities. Notable lab work includes Boston University–National Emerging Infectious Disease Laboratory, a BSL-4 lab (bio-safety level), Princeton University–neurological labs, Hospital of the University of Pennsylvania, Children’s Hospital of Philadelphia, University of Hawaii Cancer Research Center, Reading Hospital, Wistar Cancer Research Institute, Biogen, Chester County Hospital and GlaxoSmithKline.
Donal is an active member of the American Society for Healthcare Engineering (ASHE), the International Society for Pharmaceutical Engineering (ISPE), Boston Irish Business Association, the International Facilities Managers Association (IFMA). He is also an active member of the 100 Club of Boston, a charity that supports the families of Massachusetts firefighters who have been wounded or fallen in the line of duty. Donal earned his Bachelor of Arts Degree in Political Science and Government from Westfield State University.
Donal has also been selected Building Design+Construction 40 under 40 Top Young Professionals in 2017 and ENR 20 under 40 Top Young Professions in 2018.
Xinan Jiang
Vice President
Xinan has over 12 years combined experience of working on the field and coordination complex MEP systems. Her expertise includes working with design team to develop coordinated and lean set of construction documents, solving coordination issues to prevent change orders and RFIs, and working with MEP subcontractors during construction phase. With her understanding of how building infrastructure works in the field, Xinan can see how all the pieces come together and creatively recommend how to bring the intent of a design to life—in a way that typically saves the owner significantly on time and costs.
Xinan has worked on wide variety of projects including healthcare, life science, hotels, stadium, chiller plant, data center, high-rises, commercial, and museum, which includes Boston University–National Emerging Infectious Disease Laboratory, Abington Hospital, Princeton Hoyt Lab & Princeton Art Museum, Spark Therapeutics Lab, Biogen Lab, Children’s Hospital of Philadelphia, Comcast Tower, Wells fargo, MOD VII Chiller Plant, Microsoft, Google, Apple.
Xinan has also been selected ENR 20 under 40 Top Young Professions in 2019.
