Our Building Envelope Consulting Services

d7 service design

Designs | Drawings | Specs | Peer Reviews

D 7 provides the overall Design for Building Envelope systems such as Waterproofing, Roofing, Flashing and Air Barrier. To support the design, we will provide the details as they relate to the system and in the format required by the Architect. We provide written specifications for use in developing costs for the project as well as setting the technical requirements for all systems. In certain projects, D 7 is required to review all documents listed above prepared by another firm. This is considered a Design review or “Peer” review.

Restoration | Replacement

When working with historical or existing buildings that are being remodeled or repurposed, D 7 provides the review of the current systems and structure to determine what the overall project requirements are for the Building Envelope. Once agreed upon by the Architect/Client, we will provide the written specifications and details for the system to be used on the project.

Due Diligence - Acquisition | Disposition

When a Developer or Owner is looking to purchase property, D 7 works as part of a team of Engineers, Architects and Consultants to review and report on the Building Envelope components as to the life expectancy, annual budgetary considerations ongoing and any other maintenance or replacement aspects of the building(s) that may be deemed necessary.

When a Building Owner is selling the building, and looks to understand what they are faced with moving forward, D 7 will prepare an honest assessment of the Building Envelope components. This becomes the Disposition document used by Owners when negotiations occur with the Buyer.
