  • RLGA Technical Services launches exam preparation site for CSI's Construction Documents Technologist (CDT) certificate program - BETA testers needed

To prepare his M. Arch. students at the Frank Lloyd Wright School of Architecture for the CDT exam, Ron Geren, owner of RLGA Technical Services, developed an online practice examination site that mimics the actual CDT exam.  Using the Canvas learning management system (LMS) developed by Instructure, the online exam provides 100 questions divided into the eight domains covered by the CDT exam.

As a result of his development of this practice exam, Ron Geren has modified it for use by members of the construction industry in preparing for the CDT.  "To my knowledge, there is no other comprehensive program that provides a full length exam that prepares students for the actual CDT exam," says Ron Geren.  The online practice exam is now available in a free BETA version.  Users of the BETA version are asked to provide feedback on the questions as well as the LMS platform.

The BETA version currently allows users to take the exam five times.  Each time a user takes the exam, the questions, as well as the answers, are randomized to create a new experience each time.  The 100 questions on the exam are drawn randomly from a bank of questions that currently has over 200 questions.  The types of questions are proportioned based on the percentages identified for each of the eight domains of the exam structure.

Although the actual CDT has 120 questions, 20 of those questions are used for "statistical validation" to see if they will be used on future exams and are not scored.  The time limit on the actual CDT exam is two hours, or 120 minutes, which is one minute per question.  For the CDT Practice Exam, only 100 questions are given, so each user is only allowed 100 minutes to take the exam, which is one minute per question.

The practice exam site also has a discussion area where users can post questions about the CDT or make suggestions for improving the practice exam.

The BETA version will remain live until the end of June, which is the end of CSI's fiscal year.  The Ron Geren will review the feedback that was received, as well as review the next fiscal year's CDT Exam Candidate Handbook, and modify the practice exam for improvement and to keep it current with any changes made in the CDT certificate program.

To become a BETA tester for CDT Practice Exam, send an email to ron@specsandcodes.com with your name and email address.  A separate invitation will be sent from Instructure with an invitation to complete the registration.

  • Ron Geren under contract with Wiley & Sons to write a professional reference/college textbook on the building code 

In January, Ron Geren, owner of RLGA Technical Services, signed a contract with John Wiley & Sons, Inc. to write a book based on his step-by-step code application method.  Tentatively titled Applying the Building Code During Design, the book is targeted for architectural professionals and students. 

"This book will provide students and practicing design professionals," says Ron Geren, "with a resource that introduces a logical and comprehensive process for applying the building code during the phases of design of a building."  Ron Geren is a professor of architecture at the Frank Lloyd Wright School of Architecture, based out of Taliesin West located in Scottsdale, Arizona. 

Ron states that the approach to code education and resources in the past has been, "Here's the code book and here're other books that explain it."  This book, according to Ron, turns that around with an approach that says, "Based on how you design buildings, here are the code requirements you need to know and when you need to consider and apply them to your design."

The book is scheduled to be published in late 2015 following the publication of the 2015 International Codes.  To concentrate on writing the book, as well as managing his practice, Ron Geren has suspended writing articles for his Keynotes and Code Corner Series until 2015.

  • The Latest Issue of Keynotes - "Common Specifying Problems"  It is not news that many sets of construction documents contain errors, whether they are found in the drawings or specifications. Construction documents are products of humans and are not warranted to be perfect. Architects and engineers are held to a standard of care that is consistent with other professions, such as attorneys and doctors, which means that they have to perform similarly to other architects or engineers who are located in the same region, at the same time, under comparable conditions. Although architects and engineers are not required to provide perfect documents, they should provide documents that are as clear, concise, complete, and correct as possible.

    Drawings errors vary, but can consist of something as simple as an incorrect dimension to something as complex as detailing an assembly that could not possibly be fabricated as shown. Many of these errors are unique to drawings, but some can be shared with specifications. Specifications, like drawings, have their unique common errors—but what may be considered an error by some may actually be just a violation of best practice. Therefore, the remainder of this article will address, in no particular order, errors and best practice violations (i.e. problems) commonly found in construction specifications.

  • The Latest Issue of The Code Corner - "High-Hazard Occupancies" The TRW plant located in Mesa, Arizona, has experienced a number of problems: explosions, fires, and medical emergencies.  Hundreds of them in a time span of less than ten years.  An explosion in 1995 cost the life of one worker.  The situation became such a concern that the Mesa Fire Department issued a cease and desist order to the owner that lasted a couple of days, but only until TRW agreed to improve conditions.  So what was at the center of all these events?  The answer: sodium azide—a chemical used in the manufacture of automobile airbag devices.  Although sodium azide (NaN3) is not classified as an explosive (it is a toxic poison), when heated, the chemical reaction generates an explosive event.

    It should be obvious to anyone reading the previous paragraph that those facilities associated with the TRW plant are hazardous occupancies.  More specifically, the International Building Code (IBC) considers occupancies such as this as high-hazard or Group H occupancies.  The IBC describes a high-hazard occupancy as one “that involves the manufacturing, processing, generation or storage of materials that constitute a physical or health hazard in quantities in excess of those allowed[.]”  The key to classifying a building as a Group H occupancy lies within the last few words of that quote: in excess of those allowed.  Without that provision, every building that has certain cleaning products in a janitorial closet would be considered a Group H occupancy.
