Building Envelope Design

Early collaboration and a design-assist approach are key to successfully delivering any facade

Our pre-construction team focuses on the development and maintenance of overall project budgets with the goal of providing design/cost solutions to the project.  Gamma’s expertise in innovative design, distinctive solutions, constructability and high-level budgets are great value to our clients. Working alongside our global resource team, Gamma has developed a domestic and global procurement strategy to ensure that we receive high quality materials from all of our pre-qualified partners. This gives us to access to worldwide product sourcing, modern technologies, and best cost & performance solutions for each project.

At Gamma we encourage a design assist duration for every project. Learning from past experiences, we believe a key milestone to a turnkey successful project starts with a design assist. Early-stage engagement allows us to establish a strong foundation to build on and allows us to detect and resolve design and constructability challenges immediately. Having Gamma involved early reduces unforeseen costs and any other issues that typically don’t
get ironed during a typical bid stage.  Most of all at Gamma, we work hard to establish/maintain strong relationships based on trust, honesty and open communication with all contractors, with one intent of turning over a successful performing envelope.

Passive House (PH) is an energy-based building standard that can reduce up to 90 percent less energy than traditional buildings. Heating and cooling loads are minimized through passive measures such as insulation, windows, passive solar energy, and shading. Our company is proficient in Passive House principles and practices in design and construction methods, to ensure the cost effectiveness and performance of your building.

Gamma operates out of two main fabrication facilities, one located in NY state and the other in province of Quebec. From this facility we have the capacity to handle a wide range of project challenges from entrance doors and window frames to large unitized pre-glazed curtain wall projects. Gamma is constantly re-investing in the latest equipment to ensure that we remain at the leading edge of our industry.  All of this translates into quality products produced quickly and efficiently for you the customer.

We employ our own forces in the field to install the products we manufacture. The field installation process is one of the most critical phases of the project. That’s why Gamma Installation department and design team always work hand in hand to assure design meets constructability. This enables us to maintain quality and consistency from project to project.
