These topics have been curated to help building owners and managers understand the basics of the building envelope, how and why it deteriorates, and how to navigate the restoration process for successful outcomes.
The Building Envelope
The building envelope comprises those systems that separate the interior from the outside world. No matter how well designed and constructed, they will eventually deteriorate and must be maintained to preserve the building’s integrity.
Over time, all buildings become antiques and require restoration to arrest—or reverse—their deterioration. Building envelope components are interconnected, and water is their main enemy.
The cast of characters for a restoration project includes: the building owner or its managing agent, restoration architects and/or engineers, contractors, and attorneys. Learning these essential roles helps owners have clear expectations of who does what.
Understanding the exterior restoration process—from investigation through construction administration—can help owners understand the art and science involved and know what to expect from restoration professionals and contractors.
Exterior restoration comprises the repair and preservation of the building envelope, a process where success is measured by how well technical, financial, and logistical considerations are met.
The essential function of the building envelope is to keep water out, and the roof is the first line of defense in that effort. Properly designed, a roofing system can be an environmental asset; Improperly designed or installed, it can fail at its most basic mission.
One of the main roles of an E/A firm is the production of Contract Documents that the restoration contractor is responsible for executing. The key to success is to address all restoration issues systematically, on paper, before a contractor is selected.
