Mainstay Engineering Group is a fast-growing firm offering structural design, civil design and land development services to owners, manufacturers, developers and design professionals. The company was founded on the belief that our group of highly talented individuals' trained in multiple disciplines of civil and structural engineering provides exceptional service.
Founded in 2002 by Matthew E. Hilbush, P.E., Mainstay Engineering Group began with a niche identity in the pharmaceutical sector. He recognized that pharmaceutical companies and pharmaceutical design firms benefitted from civil and structural services that understood the types of equipment utilized in the manufacturing, R&D and packaging facilities. Projects initially started with stainless steel platforms, mechanical mezzanines, and roof-top equipment support. William J. DiCarlo, P.E. joined the firm in 2003 as a Principal and Owner, bringing his strong technical background in pharmaceutical, petrochemical and heavy industrial projects. Mainstay gradually has grown and completed larger scale projects that include grass-roots buildings, envelope expansions, major renovations and facility site development and master planning.
Mainstay successfully leveraged experience from the pharmaceutical industry to other market sectors including university, commercial, retail, municipal and petrochemical. Today, Mainstay Engineering Group employs 12+ design professionals and performs a broad range of projects in multiple industries. We pride ourselves in effectively designing small clean room platforms to multi-million dollar university buildings and small parking lot additions to 200 acre site development projects. We are very proud of the multiple industries now served, the ability to provide efficient services for projects of varying scales and our long-standing client relationships.
