About Us


Our Mission

We will utilize the most cutting edge processes to provide the absolute best services with the most talented team available while maintaining the highest integrity.

Firm Profile

Zero/Six Consulting, LLC was founded in 2003 by Bill Coltzer Jr., AIA in response to an industry wide need for higher performing and cohesive building envelope systems. Since its establishment, Zero/Six has become a leader in delivering innovative solutions for the creation and maintenance of better building envelopes. A firm focused solely on building envelope integrity, we have assembled a staff of professionals with diverse skill sets — Architects, Engineers, LEED Green Associates, Registered Roofing Observers (RRO), Project Managers, and Field Specialists — to achieve the necessary “whole building” approach. Our extensive knowledge of glazing systems, windows, roofing systems, cladding systems and waterproofing assemblies, and those portions of your facility controlling air quality and moisture prevention will ensure an accurate assessment of both the current environment as well as future expectations. All major building systems and elements are identified and assessed, approximate remaining economic life service is determined, and budgetary cost estimates for resolving problems and deficiencies are developed to ensure the goals of our clients are met in terms of facility function, cost control, and maintenance repairs.

The three step process and the specialized expertise Zero/Six utilizes to deliver on the services set forth in each project, are as follows:

Develop the Intent (Design/Development)

Eight out of every ten construction litigation cases involve water infiltration. The Owner seeks to take delivery on a building that will prove to be an asset rather than an ongoing liability. Therefore, it is vital to establish project requirements in regards to the building enclosure at the earliest stages of the process. This can be done only by expertise in architecture that is specific to the building enclosure. Architecture – Led by our CEO Bill Coltzer Jr., AIA, a licensed Architect, with over 30 years of specialized experience in building enclosure design and specification. Mr. Coltzer will work with the client to lead his team through the schematic and design stages, insuring they satisfy the design intent.

Inspect the Product (Quality Control/Quality Assurance)

Once our client has secured construction documents that convey their intent, the next step in the process is to “Inspect the Product” through a quality control (QC) program executed by Zero/Six staff that understand how the various systems will interface. These individuals are able to go beyond just understanding how the systems interface in their investigations, as the success of the QC program is largely dependent on the ability of the inspectors to safely access hard to reach areas. Finally, as part of the QC program, deficient work will be logged as it is observed and then tracked to a resolution.

Test the Collaborative Effort (Testing)

Successful delivery of the Owner’s intent goes beyond quality control by verifying the successful collaboration of designers, manufacturers and installers through an accredited testing program. Since testing verifies design, as well as construction, the collaborative effort must be tested as early in the process as practical so repetitive deficiencies can be corrected prior to a full blown remediation effort. Zero/Six along with The Z6Cx Team is an industry leading commissioning, windstorm and stormwater engineering firm that also provides ISO-accredited building performance testing both in the field and laboratory settings, will test this collaborative effort to ensure our clients take delivery on a building that meets their intent.
