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.

For years now, the in situ relative humidity (RH) test for measuring the moisture condition of concrete has been shown to be the most reliable, accurate test available.
As far back as the 1960s, laboratories at the Portland Cement Association conducted controlled tests that verified the accuracy of RH testing. This research was followed by years of additional testing at Lund University in Sweden and elsewhere. In 2002, ASTM International first established the F2170 standard for conducting RH tests on concrete slabs.
The research confirmed two key discoveries:
Other methods typically involve taking measurements only at the surface of the slab. As the research has found, a surface-based moisture test can’t provide an accurate measure of a slab’s true moisture condition. That’s because it doesn’t account for the moisture conditions deeper within the slab, and those conditions are typically quite different than conditions at the surface.
The Standard Evolves as the Science Tells Us More
The initial ASTM F2170 for in situ RH testing was established in 2002, after continuing research at Scandinavian universities in the 1990s identified the exact specifications for conducting a reliably accurate RH test—placing the test probe at 40 percent depth for slabs poured on grade or 20 percent for slabs drying from both sides. After these scientifically-validated specifications were firmly established, ASTM International published a usable standard.
Until now, the ASTM F2170 standard has required a 72-hour waiting period between drilling the test holes where the RH probes are placed and taking official RH measurements. In practice, readings are often taken before the 72 hours has passed, so contractors have an idea of how things are trending. But because the official readings couldn’t be taken before 72 hours, that meant all decisions and work were basically on hold for those three days. Full stop.
Yet we’ve seen how the research on the RH test method has helped to refine our understanding of how best to use it. This trend continues. In 2014, a Precision and Bias (P&B) study, commissioned by the ASTM committee, tested for differences in RH readings at various intervals within the 72-hour period. In part, the idea was to assess if it is actually necessary to wait the full 72 hours for an accurate, actionable moisture readings.

If you had told me 365 days ago that I would have presented twenty-one times in twelve cities alongside my Let's Fix Construction co-founder, Cherise Lakeside, I would have laughed at you.
Every idea has to start somewhere.
When CONSTRUCT 2017 had a call for presentations, Cherise and I submitted for a 'Let's Fix Construction' workshop. What it would entail, we weren't 100% sure, but we knew that we had to get face-to-face with individuals and start talking real time about the issues that we were all facing in construction and writing about on our website.
So, what happens when you get accepted for a presentation? Not only do you have to create the presentation, but to have it go well, you need to practice! Cherise sent out two emails to two acquaintances and within two days, we had buy-ins. Not just any guinea pigs, either, but Willamette Valley CSI in Eugene and Carleton Hart Architecture in Portland, Oregon. To tack on practice, we coordinated a CSI Portland chapter meeting in downtown Portland immediately following the Carleton Hart session.
What did we learn? Our idea worked.
People within the AEC industry WANT to talk about the issues that we're all faced with. They WANT to move things forward. They WANT to make things better. They WANT to share knowledge and implement new concepts. The mightiest problem may be that we are typically operating within the contract model, not able, or not wanting to communicate directly with parties we aren't obligated to and perhaps don't have the time or place to move the laundry list of WANTS forward.
Enter Let's Fix Construction.
We had a website that was attracting eyes. We were recognized as an independent AEC industry sounding board that was unsponsored and unbiased. We provided a place, a format and the ask to share: your knowledge, your solutions and your industry answers. Three things that can be implemented and benefited from immediately. This medium was only as good as those that found their way to LetsFixConstruction.com. The workshop, however, seemed to be a different story.
The feedback was immediate and gratifying. Everyone seemed to have a takeaway. Whether it was a Monday-morning implementation, a new contact, a laugh or a new lens, those that attended and participated were engaged. It turned out that most of the time, ninety minutes wasn't enough. People wanted to keep talking. To keep sharing. To keep brainstorming.
So, we kept going. CONSTRUCT led to CSI Chapter meetings, which led to another architectural firm, which led to talking to PROSOCO customers at World of Concrete, which led to CSI Region Conferences, which led to CSC Canada's Conference and then to New York City for PROSOCO again.
And we've got more work to do.
Total World Domination doesn’t come overnight.
I look forward to where the next 365 days will be leading Let's Fix Construction.

It is an enlightening experience when you get out from behind your desk and start talking to other people in the industry. It doesn’t take much time to figure out that every discipline approaches a project and the documents from a unique and different perspective.
What is a real travesty in Architecture, Engineering and Construction (AEC) is that many of us are not getting adequate Contract Document education in our colleges, universities, trade programs or on the job. This leads to added risk, cost overruns, conflicts, disputes, time delays and sometimes even litigation. The worst part is that it is an easy thing to fix. If we were really moving forward, Contract Document education would be required for everyone working in the built environment.
Right now, our education mainly comes from a trial by fire. You screw up on the job and then you learn what you should not do again. Unfortunately, we continue to hand down bad habits, misconceptions and incorrect information from senior to junior staff. As a result, we continue to make the same mistakes. We would like to try to start fixing that.
This article is meant to give you just a taste of some of the things you should be thinking about and looking at before you submit your bid and, if awarded the contract, before you start the work. Trust us when we say there is plenty more to learn but hopefully this will give you a head start.
Every single bulleted item above has the potential to affect the time you have to spend on the work of the project, which then affects the bid you need to prepare. Nobody wants to find out after they have signed a contract that the project has extensive submittal requirements that may take a lot of hours, or an expensive mock-up or something else that you did not include in the bid because you didn’t see it. Remember, you are required to review ALL of the Contract Documents.
