Registered Waterproofing Consultant – RWC®

Applicants must meet specific requirements to become Registered Waterproofing Consultants. These requirements include verifiable levels of work experience and education, high ethical standards, and a satisfactory score on both the RWC and General Consultant Knowledge (GCK) exams.

Applicants who currently hold a Registered Roof Consultant (RRC®) and/or Registered Exterior Wall Consultant (REWC®) designation(s) are exempt from taking the GCK exam.

Although there is no separate application for the GCK exam, as approval of the RWC application will qualify candidates to take this exam, there is a study guide available.

See additional information about the GCK exam/study guide below.

General Consultant Knowledge Exam

This exam tests knowledge common to all components of the building envelope (roofing, waterproofing and exterior walls). This was designed to produce a more efficient testing process, eliminating common information being tested for each consultant designation. To earn the RWC designation, a candidate must pass the general exam as well as the RWC Exam. However, applicants who currently hold the Registered Roof Consultant (RRC) and/or Registered Exterior Wall Consultant (REWC) designation(s) are exempt from taking the GCK Exam.

If only one of the two exams is passed (the general or the technical), the candidate will be required to retake only the exam he or she failed. The exam that has been passed will be valid until the candidate passes the other exam and the first consultant designation is earned. Candidates who do not pass an exam will have the option to retry every four months with a valid application.

The exam is computer-based and offered at over 1,000 conveniently located testing locations. Visit Scantron for testing center locations. The exam is 4 hours in length and consists of 90 multiple-choice questions which test knowledge in the following general consulting areas: ethics, general skills, communications and reports, codes and standards, design processes, procurement processes, agreements, and construction administration.

All questions pertain to consulting practices in general and are applicable to all consultants, in spite of the discipline (roofing, waterproofing, exterior walls).

Note: IIBEC’s Professional Building Enclosure Consulting course is recommended for anyone planning to take the GCK exam.

IIBEC Scores a Victory as Alabama DOT Changes Procurement Regulation

By John Boling IIBEC is pleased to report that the Alabama Department of Transportation (AL DOT) agreed to modify regulations…

IIBEC Organizes Opposition to Proposed Alabama Regulation Gutting QBS

In early October IIBEC became alarmed after reading Alabama Department of Transportation (AL DOT) proposed draft regulations overhauling state procurement procedures. Specifically, the proposal instituted a new procedure for architecture, engineering, and design services based on price (low-bid) for state-funded projects, while maintaining the requirement that qualifications-based selection (QBS) is used for projects that use federal funds. IIBEC reached out to organizations in the state that also support QBS to raise the alarm and confirm the proposal was, in fact, gutting QBS for state funded projects. IIBEC submitted comments on November 4, 2022, opposing the proposal.

IIBEC Joins Industry Letter Warning of Unintended Consequences of Low Carbon Mandates

IIBEC joined the National Roofing Contractors Association and Polyisocyanurate Insulation Manufacturers Association on a November 3 letter responding to the US General Services Administration’s (GSA) request for information regarding construction materials with substantially lower embodied carbon. The response seeks to assure GSA that Environmental Product Declarations for materials used in the building enclosure sector are increasingly widely available and that designers base their material selection decisions on numerous factors. The letter makes this unambiguously clear by stating, “We oppose policies that restrict choice among design professionals and building owners based on environmental impacts alone.”
