REI Engineering can make your building work better> Charleston Business Journal


The company has extensive experience, expertise in building envelope systems that ensure, improve the longevity and efficiency of structures.

AThe chemical company hired architects and engineers to design a manufacturing plant when a fatal flaw appeared: a leak that prevented temperatures and humidity levels from being maintained in the narrow range necessary to keep chemicals stable. They were forced to stop production for weeks.

REI Engineering, the building envelope experts, were called upon to provide air infiltration testing and hydrothermal analysis. They determined that the structure required additional insulation and air barriers, and designed modifications to the existing walls that included these components. Renovation work closed the plant for a few more weeks.

The cost of fixing the problem was 10 times the cost of preventing it, which would have involved REI in the design phase.

Building owners, architects, engineers, property managers and others turn to REI engineers during the design phase for their expertise in creating a continuous exterior envelope system. Many construction problems occur at the intersection of different materials, such as exterior walls and roof, and at openings in the envelope, such as window perimeters.

Advances in materials have created an almost endless array of combinations between walls and roofs, and other transition points. Even the best general construction engineers are challenged to stay on top of all possible solutions. This is where REI comes in.

REI Engineering has the specialized skills and knowledge to provide design or design review services for roofing, exterior walls and basement waterproofing of new and existing projects. When integrated from the design stage, their collaborations with architects reduce average energy consumption by 16% on existing buildings and 13% on new projects.

REI also helps buildings fulfill their intended life cycle. When structures designed to last for decades experience unwanted air and water infiltration after five or ten years, it can dramatically shorten their lifespan.

Most architects, engineers, hospitals and schools are well aware of REI’s unique value early in the process. Municipalities have been slow to recognize this, perhaps because their new construction projects are generally more standard and have less architectural frills. Additionally, policymakers can focus more on short-term savings and the bottom line than on long-term sustainability issues. But municipal buildings require the same level of initial attention to the structural envelope to function properly and last for decades.

The city of Charleston learned this lesson during the development of the new African-American International Museum, scheduled to open in 2022. REI was hired to test the installation of building materials and detected issues with the envelope . By providing new designs that will avoid any potential long-term issues prior to the construction phase, REI has helped avoid compromising the integrity of Charleston’s newest historic cultural monument.
