This past October, Let's Fix Construction once again attended CONSTRUCT in Long Beach, California and as members of the Education Advisory Council, we found it to be one of the best yet. We are honored to partner and work with CONSTRUCT as the show holds much the same philosophy as we do here at Let’s Fix Construction: bringing all parties of the project team together to learn, discuss issues and grow as a TEAM.
CONSTRUCT offers an environment where attendees can discuss issues in a way that we often cannot under the rules of communication in a construction Contract. There are few other conferences that have representative voices from the entire built environment in a room discussing our industry and needs - all with an equal seat. The best thing about CONSTRUCT is that it is not focused on any one discipline within the AEC Industry. Architects, Specifiers, Contractors, Engineers, Consultants, Subcontractors, Product Reps and Owners all have educational opportunities to learn and further your career. The social and collaborative environment of the show makes the education provided that much more valuable.
CONSTRUCT is an annual event that offers the opportunity to share best practices, learn the latest in construction industry design and processes, project delivery, specifications, contract administration, building product manufacturer (BPM) education and much more. The education, events and show floor are all formatted in a way to serve any member of the building team. The education is enhanced by the ability to discuss and share experiences on topics that we deal with every day in this industry.
CONSTRUCT is a great conference because of the diverse industry professionals that join us to share knowledge, solutions and real-world practices that can be used as soon as you return to your office or the job site. Speakers and instructors from all across the industry join us so we can all come to the table and learn from each other.
CONSTRUCT WANTS YOU!
The Call for Sessions for 2019 is out for submissions. CONSTRUCT is looking for industry leaders - in ALL disciplines - to consider submitting a proposal to speak or teach at CONSTRUCT. Now is your chance to share your knowledge and turn what you’ve learned into a unique presentation that will help improve the construction community. Consider submitting a proposal for CONSTRUCT 2019, which will be held October 9-11 at the Gaylord National Resort and Convention Center in National Harbor, Maryland (right across the bridge from Washington DC).

That was cool - the Crash Test Dummies have done their job again! The automotive industry found a way to ensure the safety performance for their deliverable for all manufacturers to owners (us), through testing and validation. Yet when we approach the subject of performance mockups within the building community, people seemed shocked at the suggestion. After all, it might cost something to make sure it gets done right the first time – heaven forbid!
Now, consider this: buildings today utilize thousands of products, from hundreds of manufacturers, with thousands of different chemical compositions, being installed by a group with a known labor shortage, managed by groups with all different delivery methods. Try and figure out that matrix of possible outcomes. Add in the fact that very few architectural schools teach building physics to students for the understanding of heat, air, and moisture transfer, and it is no wonder insurance claims and litigation from moisture and water issues in construction is a billion-dollar industry annually.
Let’s also ask the question: how many architectural firms have chemists or research and development labs or full-scale testing facilities? Very few. But as an industry, we are asking the architect to provide product choices in specifications and properly designed and detailed projects, with the full knowledge that no single person or firm could possibly know or understand all the technologies available for all six sides of the enclosure. So…how can the Owner be assured his building is being properly built? Use the building industry’s “Crash Test Dummy” – the performance mockup.
The performance mockup is used to validate the design, product selection, and proper installation of materials, prior to the final installation on the building. Would you build a car in your backyard for your 16-year-old to drive on the expressway at 70 MPH? If you answered no, then why would you expect a unique combination of design, materials, and installers to be able to successfully provide an Owner with a leak-free building on their first try? Remember…. every building is UNIQUE. Even if you use the exact same design from project to project, you must add in the experience, or lack thereof, of the installers for each building. So, consider even if you design and select the exact same materials for two identical buildings, there is no feasible way they could be built in the exact same weather conditions, with the exact same labor force. It is impossible!
The performance mockup can be built and tested in a myriad of configurations and at all levels of cost. The most important part is that they are tested - for water leakage, air leakage, thermal concerns and durability. Make sure people installing the mockup are also going to be working on the project. What good does it do the project if the knowledge gained by the mockup is not available for the actual construction of the project? Let’s do it right on the building the first time and aim to get the lawyers and litigation out of construction.
This is the first in a four-part series on performance mockups. Stay tuned for more information.

The flooring industry is constantly challenged by the same repeating issues. Installing too early, wet concrete, non-flat sub-floors, sub-floor surface not prepared, heat not on, windows not in and lack of installer training and certification. In fact, as construction speeds up to meet demands for faster build times and with the threat of an increase in the cost of borrowing money lurking in the economic wings, the provision of acceptable conditions for the flooring contractor is becoming less likely.
This raises the importance of supporting those in the construction team (Building Owner, Construction Manager, General Contractor, Design Authority, and Flooring Contractor) with good, timely information that helps all involved plan ahead for the floor covering installation. As one of the last significant trades onsite, the flooring contractor needs certain conditions, that if not planned for in advance, will be next to impossible for the Construction Manager/General Contractor to provide without extra time and/or extra money: two things in short supply at the end of a build or renovation.
Change is possible, but requires a few things to be understood and acted on in advance.
There is a generic Canadian floor covering industry reference manual available for specification, which supports all construction parties, and when included in the Division 09 section of the construction documents, means correct flooring processes and supportive language is available to guide the floor installation and all the points listed below.

The blockchain is a type of decentralized public ledger that makes it easier to organize, verify, and protect information. While it's mainly been associated with cryptocurrencies like Bitcoin, the technology has much more potential than that. It's been theoretically applied to almost every sector of the economy and is slowly transitioning from the possible to the practical.
Blockchain may be able to tighten up construction deadlines, prevent fraud, and cut out the middlemen all while encouraging new ideas and partnerships.
What the Blockchain Does
The blockchain is a revolutionary way to input information and secure it from anyone who shouldn't have access to it. Not only can it keep financial transactions safe from prying eyes, but it can also streamline construction projects with multiple moving parts. Between investors, developers, and construction workers, it's easy for information to slip through the cracks. But the blockchain isn't like any other project management tool anyone's ever used before.
Using Smart Contracts
A smart contract is a series of if/then statements that are set up according to the rules of each project. The blockchain is dominated by the logistics of the programmer, so it can be adapted to small and large projects alike. Construction companies can use these smart contracts to essentially control every aspect of the project. So, if a painter needs to wait for an inspector to first check the drywall before painting, there will be an unhackable log where they can plainly see whether or not an inspector has held up their end of the bargain.
The blockchain makes it easier than ever for construction crews to keep up with new technology on the scene. For example, Building Information Modeling (BIM) tools may have helped to improve precision during construction, but it's also led to a lot of confusion on the actual job site. When changes can be made faster than ever, workers need a single source to receive updates in real-time. The blockchain can update everyone that the developers want a new color of paint in the bathroom or slightly different dimensions in the master bathroom.
Finding the Right People
There is a lot of segregation in construction, which leads to the isolation of ideas and talent. This separation is (in part) due to the fact that it's difficult to both find and coordinate with the right partners. Much like with picking the right real estate agent to work with, if there isn't an easy way to assess a company's reputation, it can lead to undue competition. The blockchain can both facilitate coordination and inspire partnerships between companies with different specialties. This type of cross-pollination of skills can lead to some truly innovative results in the industry.

The finishing trades most often come into play at the end of the construction project. In many cases, the end result is decorative, ornamental, and breathes life into the vision of the finished project. The installation of ceramic tile and natural stone is a finishing trade which must deliver on an aesthetically pleasing expectation AND be a resilient, long lasting, wearing surface. Unfortunately, all too often, critical installation methods and standards are not followed, with the end result culminating in failure.
Ironically, this uptick in installation failure comes at a time when the combined forces of the tile and stone industry are proactively reaching out to offer training and certification for contractors and installers. The National Tile Contractors Association (NTCA), The Ceramic Tile Education Foundation (CTEF), and Advanced Certifications for Tile Installers (ACT) are just some of the organizations offering comprehensive education and training.
The downturn in the construction industry, which occurred during the last recession, saw a vast outflow of qualified installers from the industry. The challenge still remains to locate and train individuals to address the demands of a rebounding trade. This challenge has played a role in some of the nagging failure issues that continue to occur. These failures are based more on a lack of installer knowledge and competence, then deliberate shoddy practices.
Simply put, yes, you “really have to do that”, follow the ANSI or ASTM standard that is, if you want to steer clear of problems and failures. Listed below are just two of the concerns which need to be addressed in today’s ceramic tile and stone industry.
If there is one overwhelming area of concern when it comes to the success or failure of a tile or stone installation, it would be the adequate bonding of the tile or stone to the substrate. ANSI A108.5-2.2.2 outlines the process of achieving the coverage needed to bond tile or stone to the wall or floor substrate. Summarized, the adhesive used to bond the tile or stone must be applied uniformly and evenly to the substrate; no “rainbow arches of adhesive”, no “five spotting” or daubs of adhesive placed in irregular fashion on the substrate, serving as “targets” for bonding of tile.
Minimum coverage required (the amount of bonding agent affixed to the underside of the tile) can range from 80% in “dry” areas to 95% in wet areas. Wet area bonding has heightened concern, as any voids in the setting bed can serve to trap moisture and result in microbial growth (mold). The lack of adequate bond between the substrate and tile or stone finished surfaces is the culprit in all too many failures.
Wet area waterproofing concerns continue to plague tile and stone installations as well. Of growing concern is the need for tile and stone shower detail to withstand vapor migration, as steam/vapor (resulting from shower usage) migrates to behind the tiled shower wall. The moisture damages the interior wall details and oftentimes finds a food source that contributes to mold.
ASTM E96 Procedure E is a performance standard for waterproof membrane systems, which when called out in specifications ensures a “steam room” level of performance on the shower walls of these wet areas. Typically, the products meeting this standard are applied to the outer face of a suitable wall substrate in shower details, with the tile then bonded to the membrane. When assessing the viability of product to be used with regard to this ASTM standard, be sure to source independent third party testing for validating a product’s performance claims.
There is now language and documentation available to architects and specification writers which calls for qualified labor, and is available from the National Tile Contractors Association. Implementation of this language would aid industry efforts to improve installation quality.
Let's Fix Construction is an avenue to offer creative solutions, separate myths from facts and erase misconceptions about the architecture, engineering and construction (AEC) industry.
