While hosting a Let’s Fix Construction workshop at the AIA Conference in New York City this past Friday, a theme struck me during a discussion after a team was presenting their real-world solutions to the question that was posed to them. By nature, this theme seems opposite of the AEC industry in general.
One of the many reasons why Cherise Lakeside and myself have been travelling and presenting over the last year is to help eliminate the phrase “we’ve always done it this way” in construction. The industry remains stuck in many ways and tends to not implement changes easily, nor quickly.
So, I find it nothing short of ironic that the theme that struck, the term “FAST” seems so prevalent, including one long term usage, one definition that is on the cusp and one that I’m declaring.
While not an official project delivery method on its own, the term fast-track construction seems so common in the industry nowadays, that one almost assumes the term refers to the overall pace of the construction schedule.
However, according to the CSI Project Delivery Practice Guide, ‘Fast-track (construction) is the process of overlapping activities to permit portions of construction to start prior to completion of the overall design. The project schedule may require that portions of the design and construction occur concurrently.’
It’s my belief that the presumed definition and the true definition of fast-track construction are now blurred. Overall project construction schedules and durations have been shortened for years now, even while lead times are longer than ever for certain material procurement and the workforce isn’t supporting these timelines.
Before a shovel can be put in the ground and create the new blurred definition of fast-track construction, demands are being put on designers more and more in 2018 by Owners to create what I’m going to call “Fast-track design”.
The first six (of eight) stages of the life cycle of a facility traditionally moves from project conception to project delivery to design (schematic design and design development) to construction documents to procurement to construction. While these phases could take anywhere from a few years to upwards of twenty years in the past, a new norm has compressed this timeline upwards of eighty percent in some cases. While discussing public school design with a specifier recently, they recollected how a new high school design used to be allotted eighteen to twenty-four months for design in the past and what has become all too common is the same design is now being drawn and bid in as little as six to nine months.

A cozy group gathered at the Eugene Builders Exchange this past Thursday for the May chapter meeting of the Construction Specifications Institute-Willamette Valley Chapter. The topic for the meeting was repurposedMATERIALS, the successful enterprise at the vanguard of the rapidly growing materials repurposing industry.
CSI-WVC member Alorie Mayer, who has a background in energy and resource conservation management, organized the presentation of a webinar by repurposedMATERIALS president Damon Carson. Damon founded the company in 2011, and it has only grown by leaps and bounds since then. In Damon’s words, repurposing occupies the intersection of affordability and sustainability. The repurposedMATERIALS business model involves taking byproducts out of the waste stream and extending their maximum practical benefit while minimizing waste and the expenditure of new energy to ready them for new uses.
Damon introduced the topic of repurposing materials by having us think about what many of us did naturally as preschoolers: taking an empty Quaker Oats canister and transforming it into a drum or a container for Lego blocks, or reimagining a Maytag refrigerator shipping box as a medieval fort or a space-age rocket. This, in his words, was our “substitutionary thinking” at work. Repurposing isn’t a new concept; fundamentally, it is an innately human behavior.
Damon cited the waste hierarchy pyramid and how reuse occupies a perch near its peak. Repurposing is not the same as recycling, which typically involves energy-intensive processing of the materials (e.g. chipping, shredding, grinding, or melting) before reuse is possible. Repurposing is a means to extract the maximum practical benefit from products while minimizing the cost to the environment. As a waste-management strategy, repurposing minimizes emissions of greenhouse gases, reduces pollutants, saves energy, conserves resources, creates jobs, and stimulates the development of green technologies. Repurposing rather than reprocessing previously-used items also saves time and money, making quality products available to people and organizations who may be of limited means.
Of course, repurposing isn't a new concept. Artists (like my friend and former co-worker Rosie Nice) have long fashioned sculptures and other works out of what most people would consider junk. Habitat for Humanity ReStores and Eugene/Springfield’s own BRING Recycling sell salvaged materials but tend to emphasize reuse rather than repurposing. For example, salvaged doors or windows sold by Habitat for Humanity ReStores or BRING are typically used by the purchasers for the same ends they originally were originally intended for. What distinguishes repurposedMATERIALS is its procurement of large amounts of discarded products no longer suitable for their original purposes but are otherwise practical for altogether different uses.

Construction as an industry has noticeably lagged in moving operations toward a more digital realm compared to other business verticals. A report published by McKinsey in 2017 highlighted this truth, citing a near stagnant rate of productivity growth among construction businesses. Comparing that to the 1,500 percent growth of industries like manufacturing and agriculture, it is clear construction is ripe for disruption. But those who have earned a living from the construction business, including licensed and bonded contractors and project managers, have been slow to adopt new technology over the years.
Now, however, the industry is in dire need of change. Many statistics show a labor shortage in construction, high occurrences of waste and inefficiencies on job sites, as well as skyrocketing budgets and capital spending for substantial projects. In order to combat these growing concerns and bring technology into the fold, the construction environment is starting to grasp the power of the following revolutionary changes fueled by technological tools and resources. Here are seven ways technology is influencing construction today.
Countless technology firms are focusing their energy on developing autonomous construction machinery, some led by former tech company engineers and designers. Self-operating machines, including bulldozers, excavators, and cranes, are already operating on sites around the world. Their mainstream entrance into the market is imminent in the next several years. Machines that do not require a human touch can be used to tackle repetitive, simple tasks that take skilled workers significant time and effort to complete. The inclusion of robotics in construction has the potential to reduce waste and inefficiencies across the board.
Drones and 3D Printing
In addition to self-operating machinery, the technology behind drones and 3D printing is also making its debut in the construction field. Drones have been used to help monitor job site progress, as well as lend a hand in the inspection process for projects both small and large. 3D printing offers a new way of designing projects and creating some structures that would otherwise require ample time and effort by individual construction professionals. These technologies have other far-reaching implications in construction as they become more developed and more widely used.

American’s spend more than 90% of their lives indoors. The majority of those daytime hours are set inside the office walls. Despite the rise of e-commerce and remote workers, most businesses still operate out of traditional, energy-hogging buildings.
Collectively, our country’s building stock accounts for almost half of our annual total energy usage, 3/4s of our electricity consumption, and pumps out more than 39% of CO2 emissions produced in the U.S. The World Economic Forum also reports that the Engineering & Construction (E&C) industry is the nation’s single largest consumer of raw materials like steel. The Environmental and Energy Study Institute (EESI) predicts that, conservatively, by 2025 energy use in the business sector will cost more than $430 billion – about the same as our annual Medicare spend.
Businesses have a major opportunity to reduce their environmental impact. Where do they begin? Easy. A better-built environment starts with a more sustainable building sector. We’ve collected some climate-friendly ways to make a positive contribution.
But first, some quick business.
Potential CO2 and Energy Savings
The lifespan of an average building is 50-100 years. During that time, they produce tons of CO2 emissions every day. With new construction breaking records every year, we have the ability to make huge gains regarding energy efficiency.
As ESSI points out, “If half of new commercial buildings were built to use 50% less energy, it would save over 6 million metric tons of CO2 annually for the life of the buildings—the equivalent of taking more than 1 million cars off the road every year.”
So, there it is. Problem solved, right? New builds for everyone and our climate is saved? We think taking a more realistic course is a better plan of action.
Building Better with Sustainable Solutions
Let’s face it, not every business can afford to erect an entirely new LEED-certified green building and still have money to operate out of it. But there are ways businesses and construction companies both large and small can help transform the built environment.
Though this list is by no means comprehensive, here are seven moves that can inch us toward a better-built building stock.
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.
