Using Technology to Speed Site Preparation BY MARY LOU JAY USING AIR OR WATER PRESSURE TO BREAK UP THE SOIL, AND VACUUM SUCTION TO REMOVE IT, NONDESTRUCTIVE EXCAVATION PROCESSES CAN HELP LOCATE UNDERGROUND UTILITIES WITHOUT CAUSING ANY BREAKS IN PIPES OR LINES.

I. New Tools for Excavation General contractors need to have a good understanding of a site, including the location of utilities, before they can begin any work on it. But the information they get from as-built drawings is not always accurate (if an as-built even exists), and the ground markings provided by utilities may be off by a few feet. If a heavy equipment contractor starts digging based on that inaccurate information, the result may be broken sewer or water pipes and cut electric or fiber lines. Non-destructive vacuum excavation often offers a better solution, according to Kristy Black, owner of Black Hydrovac, LLC. The system uses high pressure air or water (hydro excavation) to break up the soil, and then vacuum suction to remove it. “You can dig gently right on top of utility lines or any kind of underground infrastructure, and there is minimal risk of damage,” said Black. The evolution of these systems started 30 or 40 years ago, with sewer jetter trucks that use water pressure and vacuum suction to clean out pipelines. “Contractors realized ‘Hey, we could use that for other things,’” explained Black. The digging technology moved north to Canada where contractors started employing vacuum excavation with heated water, which enabled them to melt and then excavate the frozen ground. Today, hydro excavation is a standard excavation method in that northern country. The technology has now made its way back to the U.S., but is still unfamiliar to many in the developer/construction community. Black said it is not unusual for people to tell her, “I’ve been in the construction industry for a long time and have never heard of this before.” Precision Excavating Black emphasizes that vacuum excavation is not a replacement for heavy excavation equipment. “It will never be as fast as traditional loaders and excavators, but what we can do really well is to dig very precisely,” she explained. “We often work with site developers. There may be a big excavation that needs to happen, but they know there are some utility lines in the area. We can come in and uncover those utility lines to verify their location,” she continued. If a utility company needs a gas line installed, Black Hydrovac can dig a slot trench, excavating a very narrow, deep trench with straight lines and without a lot of soil disruption. AS THE FIRST SUBCONTRACTORS ON A BUILDING OR RENOVATION SITE, EXCAVATION AND DEMOLITION COMPANIES HAVE A BIG IMPACT ON THE PROJECT SCHEDULE. NEW TECHNOLOGIES THAT IMPROVE THEIR EFFICIENCY ENABLES THESE SITE-PREP COMPANIES TO SET A GOOD PACE FOR THE PROJECT AND A GOOD STARTING POINT FOR THE SUBCONTRACTORS WHO WILL FOLLOW THEM.

Each truck is equipped with high pressure air or water digging lances that propel the air or water into the ground to loosen the soil. Then a large vacuum hose is used to suction the soil into the truck’s debris tank. The trucks have a 13-yard debris tank where this excavated soil is stored. Black Hydrovac’s hydrovac trucks feature large water tanks that hold up to 1,600 gallons of water. Air compressors on the trucks power the air lances and other air-powered tools like jack hammers and tampers. Hydrovac excavations are faster, so they are better at slot trenching and deeper excavations. The speed at which the excavation proceeds varies according to the soil in the excavation area. “On our best day we dug a 2-foot-deep trench that was 100 feet long, but normally it would be about 50 feet,” said Black. Air excavations are sometimes slower, but their great advantage is that they keep the soil dry. They are primarily used when a hole needs to be immediately backfilled. Since the dirt removed from this type of excavation site is not wet, it can be immediately reused on the excavated site or elsewhere. Air excavations are often used to dig potholes to verify utility placement on road construction projects. “We will break through the asphalt, uncover utility lines, take measurements and pictures and then refill the trench and patch the asphalt before we leave the site,” said Black.

Another advantage to non-destructive excavation is that it can be done from a distance; hoses can be added to extend the vacuum 100 to 1,000 feet from the truck. That makes it a good solution for excavating in really tight spaces, including the inside of buildings where a backhoe couldn’t pass through the doors, Black said. Black Hydrovac crews have worked to locate utility lines in a variety of locations, including data centers, airports and federal buildings. Since the hydrovac process can be used even when the ground is frozen, Black hopes that developers will employ it to get a jump-start on projects during the winter months, enabling them to move up their construction timetables. Black expects developers and contractors will find more ways to take advantage of nondestructive excavation in the future. “One of the things that I found really interesting about this type of work is that it is not well known, and its possibilities are still being discovered,” she said. II. Increasing Safety and Productivity ISI Demolition does everything possible to protect its workers, whether they are gutting a building, razing a building or performing any demolition-related task. That is why the company has incorporated many new technology tools into its operations over the last decade. “We stay on top of the latest technology that can help us to perform our demolition work efficiently, with more controls in place to ensure the work is done to the highest standard and is performed safely,” said Paul Harkins, ISI Demolition’s executive vice president. One example is ISI’s use of remote-controlled equipment. “We have an extensive fleet of robotic equipment that allows us to perform dangerous aspects of demolition work without putting our employees into unsafe areas,” Harkins said. The company employed Brokk robotic equipment on the extensive interior demolition of 555 Pennsylvania Avenue, the former home of the Newseum, in Washington, D.C. Johns Hopkins University bought the property and is converting it into a building that will house its D.C.-based academic programs. “The implementation of robotics into that project was paramount. There were intensive structural alterations to the building, including taking out many of the existing structural members and floors,” said Harkins. The company was able to use the remote-controlled machines in places where it would not have been feasible to deploy manned equipment. Brokk robotic machines took on some potentially dangerous jackhammering at the site. “You could put the machine out on the edges of the higher elevations and hammer away the concrete, without putting your personnel in harm’s way,” Harkins explained. “These machines are incredibly maneuverable, can go into tight areas, and have the power of much larger man-operated equipment. They enhance production and safety for our projects.” A variety of attachments enables the robotic equipment to perform many different tasks. The Brokk robotic machines are compact because they do not require a seating area or the safety features required in man-operated equipment. They come in a variety of sizes, enabling ISI to deploy them on many different jobsites. The machine on the Johns Hopkins University Pennsylvania Avenue job was small; it could fit through a 3-foot-wide doorway. Once in place, the expanded outriggers that helped stabilize the equipment increased its footprint to about 8 feet. Fully expanded, the machine is approximately 14-feet long and can be compacted down to just 6 feet.

The equipment operators can stand a few feet away or 100 feet away, if needed, to control the robot as work progresses. “There are also applications where you can have cameras on the machines so that the operators don’t have to be in the same room,” said Harkins. Robots are especially valuable for tasks that must be performed in tight, enclosed areas where there is not a lot of ventilation. People using gas-powered machines couldn’t work in those areas, since the exhaust would fill the room with carbon dioxide. That is not a problem with the robotic equipment, which runs on generators that can be placed away from the work area. “The machine gets the power it needs to do the work with no emissions,” said Harkins. ISI is also using robotic equipment in its saw-cutting division, enabling employees to remotely control those operations from a distance. “On certain pieces of equipment, we use cameras at the end of our high-reach excavator tool that allow the operators to see a point of work that may be hundreds of feet away, up in the air. That creates a more efficient and safer process,” Harkins added. ISI has also used Brokk equipment to remove some of Baltimore/Washington International Airport’s (BWI’s) concourse areas, places where it couldn’t get regular equipment. In Crystal City, Virginia, remote-controlled Brokk robots were used to help transform The Helix, the future home of Amazon HQ2. The company currently deploys the Brokk machines on a daily basis, using them on approximately 30 to 40 percent of their jobs. “With the power they have, they are the most efficient process for certain types of locations, and they expedite the work tremendously,” said Harkins. Pre-Bid to Site Work ISI’s technology deployment actually begins well before the deconstruction process gets underway. The company uses software like BuildingConnected to ensure that it knows about demolition projects out for bid. It relies on Bluebeam software and an in-house-developed software program to assist in pricing the project and evaluating how their bid compares with historical data. Creating a Building Information Modeling (BIM) model helps ISI gain a more thorough understanding of the complex jobs it undertakes. With BIM, the company can perform deconstruction assessment, design the right shoring system for the project and analyze the effects the demolition process will have on the existing structures that will remain in the building. “We are able to put together the best approach to the project and also demonstrate that process to our clients. It then allows us to clearly show our field team how we approached the project at bid time,” Harkins said. “We have found this process to save time and money in the field because the process of execution is made extremely clear. There is no lost time because of poor communication or understanding of the work plan,” he added. ISI employs PlanGrid software to organize large amounts of information about the project and to provide the field team — project managers, superintendents and foremen — with every document associated with the project. Equipping the field team with iPads enables them to access this information quickly and to participate in video conferences. ALTHOUGH THE TECHNOLOGY IS STILL NEW AND NOT FULLY DEVELOPED, HARKINS HOPES THEY WILL EVENTUALLY BE ABLE TO PROGRAM GPS INFORMATION FROM THE BIM MODEL INTO THE AUTONOMOUS ROBOT, WHICH COULD USE THAT INFORMATION TO PERFORM THE WORK WITHOUT OPERATOR INTERVENTION. 10 BUILDING WASHINGTON

Contaminated Soils Present Special Excavation Challenges Many construction sites, today, in the D.C. metro area have contaminated soil. That complicates the work of excavation contractors like Goldin & Stafford, LLC. One former industrial site was particularly challenging for the company because it had multiple contaminants in different areas and at different depths. For this job, project managers divided the work area into 14 grids of 50-square-feet grids and two, 25-feet-square grids. They then took samples of each grid every 5 feet down until they reached the 24-foot excavation depth. The samples went to laboratory for testing. After Goldin & Stafford received the results, they had to send the information out to different soil acceptance facilities to determine which would accept the soil from a particular grid at a particular level. “Sometimes we would get the results back and the facility would want some more data from a certain grid. We would have to go back to the site and resample it,” said Sid Chapman, the company’s vice president of operations. Goldin & Stafford worked with the testing laboratory, several acceptance facilities, the District of Columbia’s Department of Energy & Environment and the U.S. Environmental Protection Agency (EPA) to determine that all soil was directed to the proper site. In all, the testing phase of the project took nine months. The company eventually found four different acceptance facilities for the soil. Once site work got underway, it had to ensure that every section of dirt that it removed was loaded into the right truck and sent to the right facility. That meant there were multiple trucks headed to different sites each day. The job was further complicated by the fact that the Pittsburg area facility that took the lead-contaminated soil would only accept seven truckloads of soil a day. Drop-offs (and the seven trucks to handle the loads) had to be scheduled a week in advance. “On this job, we couldn’t cancel the trucks, so we worked through the rain, the snow and everything else,” said Justin Fanning, Goldin & Stafford’s vice president of estimating. Site logistics were complicated. Since trucks cannot line up on the District streets, they had to be staged off site and then driven through narrow, two-way streets to the project location. Goldin & Stafford had an average of 25 trucks on site each day, removing about 500 yards of soil. Over the course of the project, that amounted to about 1,074 loads of dirt. To keep the project on schedule — and to work around the shortage of truck drivers available each day — Goldin & Stafford worked six days a week on this project. Despite all of the challenges of dealing with the contaminated soil, the company was able to get its work completed on time and ready for other subcontractors to come onto the job.

Before work begins, ISI uses drones and 360-degree cameras to take images of site conditions, documenting any existing cracks or potential problem areas. This process continues throughout the project to document the company’s progress on the job. “We have instant communication in the field because of these technologies; all of our reports are in real time,” said Harkins. That is especially helpful when crews open a wall and find some unexpected challenges. “I don’t think there is a day when I am not on a video conference or a video session with our field crew because of an unforeseen issue. Before, we would have gotten in a car and driven someplace to take a look at the jobsite. Now, our field personnel can pull it up at a video conference and show us the issue. Sometimes we have to forward that to the designers of the project, and we get answers in the same day. Before it might have taken weeks to get that done.” GPS systems enable ISI to track the location, usage hours and mileage of its equipment. The software also notifies ISI’s shop when a piece of equipment needs maintenance. Ensuring the equipment is running at optimal conditions at all times has boosted productivity, Harkins added. GPS-equipped autonomous vehicles will one day be more significant on the jobsite. The technology is still new and not fully developed. Harkins hopes they will eventually be able to program GPS information from the BIM model into the autonomous robot, which could use that information to perform the work without operator intervention and just operator oversight. ISI will continue to search out new, beneficial technology, Harkins said. “ISI is proactive in all phases of our business process to make sure we know of the latest technology available in the industry and to integrate that technology into our work process as much as possible,” he added. “Technology is key to giving our team the best equipment and processes available to make their work safer and more efficient.” n THIS HIGH-REACH, ROBOTIC EXCAVATION WITH MULTIPROCESSOR ATTACHMENT IS EQUIPPED WITH A CAMERA, ENABLING AN OPERATOR ON THE GROUND TO CONTROL DEMOLITION ACTIVITIES ON THE BUILDING’S FOURTH FLOOR.

PLANTED ACREAGE IN THE D.C. METRO AREA IS INCREASING, BUT MOST OF IT IS NOT FOUND AT STREET LEVEL. IT IS ALL ABOVE THE GROUND, ON THE GREEN ROOFS THAT ARE PROLIFERATING THROUGHOUT THE DISTRICT OF COLUMBIA AND ITS SUBURBS. There is a good reason for this high-level, green infrastructure buildout. Over the past three decades, the District of Columbia’s rapid growth, and the accompanying paving-over of pervious surfaces, led to a 34 percent increase in stormwater runoff. With sewer discharge and stormwater sharing the same large pipes in some areas, a rapid influx of water sometimes ends up sending sewage into nearby rivers. Montgomery County and Prince George’s County in Maryland are experiencing similar strains on their stormwater systems. To reduce that flow, D.C. adopted the Green Area Ratio Rule in 2016. It set a minimum requirement for water-retaining landscaping for every new construction and exterior renovation project on a commercial building. Since land in the District is expensive, the city allowed owners to install green roofs to meet this minimum. “Green roof systems can capture and retain anywhere from 50 to 80 percent of the rainwater that falls on them,” explained Vanessa Keitges, president and CEO of Columbia Green Technologies, which designs and manufactures vegetative roof technologies. The other 20 to 50 percent of the rainfall is disbursed to the stormwater system over time and helps prevent flooding damage and combined sewage overflows. The green roof is a cost-effective way for developers and owners to meet stormwater mandates. In an urban environment, a tank in the ground capable of holding that much water would take up valuable space that could be used for a basement or parking lot.

There are two major categories of green roofs. Extensive green roofs have less-growing media, often around 3 to 4 inches deep. They add 30 to 50 pounds per square feet to the roof load and are planted with low maintenance, drought-resistant plants. Intensive green roofs have deeper substrates (up to 12 inches) and increase the roof load by anywhere from 40 to 150 pounds per square foot. They feature a variety of plants and require more maintenance, including irrigation. Because they are less complex, extensive green roofs are much less expensive to install than intensive roofs. About 80 percent of the green roofs constructed today are extensive. Green roofs offer many benefits beyond stormwater management/water retention. Although they cannot be used in place of roof insulation, they do provide an extra layer of protection. They help reduce energy use by keeping warm air in the building during the cold months and absorbing heat from the sun in the summer. They also provide some sound insulation. Green roofs last longer (40-plus years) than conventional roofs because the plantings protect the roofing materials from the sun’s UV rays and from temperature extremes. The plantings also reduce CO2 and increase oxygen production. Installation Options Architects, landscape designers and engineers develop the plans for green roofs, usually assisted by the material manufacturers/suppliers. The installation is done by roofing contractors and/or landscape contractors. “Choosing a great design team, green roof system and trained green roof installers is key to a successful green roof that will be green on day one and for years to come,” said Keitges. She noted that in the D.C. market, too many green roofs have failed, which costs the owners a lot of money The Basics of Green Roofs Green roofs vary in their design. They generally consist of several layers, from the bottom up, that include the deck, waterproofing, insulation, roof barrier, drainage, filter fabric, growing media and plants. Existing buildings that are being renovated may require reengineering and additional support to handle this additional load. The growing media on a green roof is specially designed to reduce weight, ensure proper drainage and help the plants thrive in the environment. It is made from both organic and inorganic material; while it may contain soil, it often does not. MUSEUM OF THE BIBLE UTILIZED BOTH EXTENSIVE AND INTENSIVE ROOF ELEMENTS.

long term. The District of Columbia’s Department of Energy & Environment inspects green roofs after three years and fines the owners if they are not thriving. Keitges recommends choosing a single contractor and a single green roof system for both the extensive and intensive areas of a green roof. This will ensure the work is done in accordance with all installation, specifications and warranty requirements. It keeps costs down for the general contractor and makes it easier for the owner to maintain, over time, since they will have one green roof system, one warranty and one green roof professional to call. In the D.C. metro area, roofing companies today handle about 80 percent of the extensive roof work in the area, according to Dan Kauffman, commercial installation business development manager at Chapel Valley Landscape Company. “Extensive plantings are not very difficult; they are much more like putting your carpet or sod down in many cases,” he said. Chapel Valley was a pioneer in green roofs in the metro area and has been installing them for more than 25 years. Today, the company works mainly on the more complex intensive green roof systems, which require a greater understanding of landscape design and plants. Working on a rooftop does require added safety precautions. But otherwise, it is much like the ground-level work that Chapel Valley does, Kaufman said. “The primary difference is that we are planting into scientifically modified soils instead of planting into the ground. One of the things that we do know is how well the soil is going to work ahead of time, so there is less risk,” he said. Getting the planting medium up to the rooftop may require the use of a blower with a hose that can reach as high as 15 stories. Other times the company has to bring both soil and plantings up to the rooftop using a crane. The plants chosen for a green roof must be compatible with the mid-Atlantic climate and able to withstand the tough conditions on a D.C. rooftop, where temperatures can reach 110 degrees in the summer. For extensive roofs, the choice is usually sedum, which provides some color. Chapel Valley also uses drought-tolerant grasses and sedges. To meet government requirements, extensive green roofs cannot rely on irrigation to survive once they are planted. “To gain full credit for stormwater management, temporary irrigation systems have to be removed or disabled inside of two years,” Kauffman said.

He noted that the green roof materials are continuing to evolve. Chapel Valley, for example, has recently been doing more green roof biofilters. These systems replace some of the aggregate materials in the growing medium with sand to provide a better filtering system. The company is also seeing more very-thin-gauged metal walls being used as planters to contain the soil. Although green roofs are now a proven technology, Kauffman said that some owners still have concerns about how rooftop plantings will affect their roofs over the long term. That’s one reason Chapel Valley sticks to registered green roofing systems that are backed by warranty. When a green roof does fail, it is often not the system’s fault. Chapel Valley installed one green roof in the mid-1990s; at the time, it was the largest green roof east of the Mississippi. Twelve years later, the end user, who was performing some rooftop experiments, accidentally drove stakes into the rooftop, puncturing the waterproof membrane. As a result, the entire roof and all its plantings had to be removed before Chapel Valley could install a new green roof. Rebates Available for Some Green Roof Installations There is some financial assistance available for building owners who need (or want) to install green roofs on their buildings. The District of Columbia offers the RiverSmart Rooftops Green Roof Rebate program for residential, commercial and institutional buildings located within the Municipal Separate Storm Sewer System (MS4) area. The rebate is $15 per square foot for voluntary installation of a green roof. Grants are distributed on a first-come, first-served basis, and there is no cap on the size of projects eligible for reimbursement. District residents, businesses and property owners who reduce stormwater runoff by installing a green roof or other green infrastructure may also be eligible for the RiverSmart Rewards program. They can earn a discount of up to 55 percent off the stormwater fee assessed by the District’s Department of Energy & Environment. In Prince George’s County, houses, commercial businesses, multifamily dwellings and other buildings may be eligible for a rebate for installing a green roof on an existing building. The county’s Rain Check Rebate program offers a rebate to individuals, commercial businesses, multifamily dwellings and nonprofit organizations (including housing cooperatives) that install green roofs on buildings within the county. The rebate for residential and business extensive green roofs is $10 per square foot, with a limit of $4,000 for homes. For an intensive green roof, nonresidential properties only, the rebates are $20 per square foot. Montgomery County’s RainScapes Rewards Rebates program offers a $9 per square foot rebate for green roof installations, with a maximum of $7,500 per property for residential structures and $20,000 for nonresidential.

Opening Up Green Space Green roofs do not just solve stormwater issues. More and more — and especially since the pandemic — designers and building owners are thinking about green roofs in a different way. “They are considering how they can use green roof spaces to provide people with more access to natural air and light,” said Keitges. The largest example of that trend is The Perch skypark, which was built on top of the 11-story Capital One Center in Tysons, Virginia. Ruppert Landscape, Inc. did the installation, and Columbia Green provided the materials and construction support for the 2.5-acre park, which includes a beer garden, an amphitheater for musical and theatrical performances (with a giant screen for watching sporting events), a dog park, bocce ball courts, lawn areas and a sculpture garden. It is the largest rooftop park open to the public in the U.S. Other developers are following suit to help draw people back to urban areas by designing their buildings to include a park on the roof. Building owners do not have to install a lavish green rooftop park to make a difference in the overall environment. One example is Sibley Memorial Hospital in D.C., which recently added an extensive green roof from Columbia Green on top of its surgical center. This 8,000-square-foot area retains more than 105,000 gallons of rainwater annually, and both the patients and the doctors enjoy looking over it. Research shows that such green spaces in hospitals bring many physical and mental benefits, said Keitges. Just looking at natural elements can lower a patient’s blood pressure, reduce heart rate, lessen the need for pain medication and decrease the number of minor post-operative complications. Since stormwater remediation will remain a primary objective of urban governments for many years, green roofs will continue to sprout up across the D.C. market. Their designs will change as designers develop new technologies and new uses for them. In the future, the green space atop a 20-story apartment complex or office building could also be used for urban agriculture, fulfilling the dual purpose of alleviating stormwater runoff while supplying fresh produce to city residents. n GUESTS AT AN OUTDOOR CONCERT AT THE PERCH.

Over the last six decades, ABC of Metro Washington has advocated for its members in a variety of ways. While most people think of advocacy as speaking out on behalf of an organization, other activities are included in that concept. In the political arena, especially, advocacy requires the association to be alert to what is happening behind the scenes that could impact merit shop contractors and be prepared to step in and act as necessary. ABC of Metro Washington’s advocacy efforts help ensure that contractors do not get blindsided by legislative and regulatory agency activities. That effort requires day-to-day involvement and includes conversations with contacts in the District of Columbia’s City Hall and Council and in the Maryland legislative and executive branches. It also involves monitoring bills and regulations that are of interest to the industry. The association’s staff and lobbyists are looking at both industry-specific issues and general economic or regulatory issues (like changes to licensure requirements) that could impact the construction industry. “We try to act as an early warning radar system for the industry through the association,” said Ben Young, of Georgetown Public Affairs, ABC of Metro Washington’s consultants in the District of Columbia. Advocacy is important because ABC members are busy running complicated, sophisticated businesses. They do not have the time ADVOCACY FOR MERIT SHOP CONTRACTORS HAS BEEN AT THE HEART OF ABC’S MISSION SINCE ITS INCEPTION. BACK IN THE 1950S, WHEN CONSTRUCTION LABOR UNIONS WERE DOING THEIR BEST TO FORCE MERIT SHOP CONTRACTORS OUT OF BUSINESS, THE FOUNDING MEMBERS OF THE FIRST ABC CHAPTER SAW THE BENEFIT OF HAVING AN ORGANIZATION THAT COULD ARTICULATE THEIR VIEWS AND ACT ON THEIR BEHALF. GENERAL CONTRACTOR CHARLES MULLAN, WHO OWNED ONE OF THE SIX COMPANIES THAT STARTED THE ASSOCIATION, EXPLAINED THEIR REASONING: “WE COULD HAVE STAYED OPEN SHOP AND FOUGHT WITHOUT FORMING ABC, BUT BY JOINING HANDS, IT MADE EVERYBODY STRONGER.” (FROM FREEDOM IN THE WORKPLACE BY SAMUEL COOK.) BY MARY LOU JAY WHY MATTERS ADVOCACY 20 BUILDING WASHINGTON F EATURE

(and may not have the inclination) to monitor these activities themselves. “What ABC does through its lobbyists is guard the industry’s flank so that contractors do not have to divide their attention. They can concentrate on running their businesses,” said David Catania of Georgetown Public Affairs. “Advocacy helps protect their livelihood because it defends their way of doing business,” said Marcus Jackson, ABC of Metro Washington’s director of government affairs. Advocating in D.C. In the 1950s, merit shop companies often had to deal with others in the construction industry who wanted to shut their jobsites down. The threats to merit shop businesses take a different form today, but they can be just as detrimental to a company’s bottom line. Part of the problem in the District of Columbia is the speed at which a proposal can become law. In Maryland, a bill has to go through committee hearings in the House of Delegates and the Senate before it can reach the floor of the legislative chambers. In the District of Columbia, however, a councilperson can introduce an “emergency” bill on a Thursday and it can become law by the following Tuesday without any hearings and without any real notice. “In the District, you have one layer for government. It is the most all-encompassing, powerful legislature in the country,” said Catania. The situation is further complicated by the fact that committee chairs are immensely powerful in this system, and most Council members will usually go along with their recommendations on a bill. Since the District of Columbia is the site of the U.S. government, its residents and Council members are much more aware of what happens on the federal level. That means federal lobbyists for varying organizations often end up talking to local politicians as well. Those organizations may try to convince the D.C. City Council to adopt a proposal, often not businessfriendly, that cannot make it through the federal legislative process. Once that kind of proposal becomes law in D.C., council members in nearby Maryland counties may decide that they want to pass similar legislation as well. In addition, the D.C. Council is in session year-round, so there is no downtime. A bill impacting the industry could be introduced at any time. “You have to be a subject matter expert, watching this like a hawk, and even when you are, you have to know how to maneuver if you want to stop something from happening. And that is a very narrow window,” said Catania. There is one other basic problem; the City Council members often have no experience of running or working in a business. So, advocacy often involves explaining to those representatives how a well-intentioned piece of legislation could have devastating effects on a business. Maryland Advocacy Issues Harris Jones & Malone, ABC of Metro Washington’s lobbying firm in Maryland, faces similar challenges. It has more time to advocate for the position of merit shop members on proposed legislation, but it also has more jurisdictions to cover. The firm keeps an eye out and ears open not only for legislative and regulatory activities at the state level, but also at county and local governments as well. “Sometimes what you see on a local level finds its way to the Maryland General Assembly. Sometimes when something does not pass in the Maryland General Assembly, whoever is trying to push for the change may decide to try to implement it jurisdiction-by-jurisdiction,” explained Lisa Harris Jones. At the state level, advocacy involves making sure that the merit shop message is getting to the right people in government. When there is a bill or a regulation under consideration, for example, it is important that ABC and its members be represented by someone who understands the procedure for getting bills passed or regulations adopted and who knows how to intervene at the right time. “We can step in and try to either reshape a bill with amendments or push a bill over the finish line,” said Harris Jones. Advocacy also means explaining to government officials what ABC members do and why they are important to Maryland’s communities and economy. “If they do not know what ABC members are doing, what projects they are working on, who they employ, where they live and where their businesses are located, legislators will not consider the effect legislation will have on those members when they are introducing or voting on bills,” said Harris Jones.

It is also important that legislators understand who really does the majority of the construction work in the state. Even though organized labor is only 10 percent of the industry, they sometimes draw from other areas of organized labor to amplify their voice. “That gives the impression that they are 90 percent of the industry, which they are not,” said Tommy Tompsett, also with Harris Jones and Malone. “So constant advocacy is not always just asking for something, it is educating legislators. It is important for them to understand what ABC members are contributing to the fabric of Maryland as a whole.” Advocacy Wins The evidence of ABC of Metro Washington’s success in advocating for its members can sometimes be seen in the laws that they help get passed. In most cases, however, the association’s wins are not as visible, because they consist of bills that do not get passed or regulations that do not get implemented. During Maryland’s last legislative session, for example, a unionsupported measure in an occupational health bill would have required companies to pay all essential workers, including those in construction, an extra $3 per hour in hazard pay. “That was an instance when having an advocacy team working with elected officials was a benefit, because we were able to prevent something that would have been devastating to all contractors,” said Jackson. The impact of the bill would have been especially difficult for small and minority businesses, wreaking havoc on their budgets. Last year, ABC of Metro Washington’s advocacy on behalf of its members helped defeat a last-minute attempt to add a project labor agreement to a funding bill for the additional traffic lanes on I-95/and I-495/I-270. “That is when we are at our best. We were able to work with elected officials and have them see our concerns,” Jackson said. ABC of Metro Washington will need its advocates more than ever in 2022. Marylanders will be electing a new governor, a new attorney general and new legislators. Elections will be the major focus in the District of Columbia as well. There will be other issues of interest to the industry as well. Jackson said that both the District of Columbia and Maryland might take steps to legalize the recreational use of cannabis. ABC’s efforts in this area will focus on making sure that contractors get a safety exemption so they can continue to test for the drug. Not every election or every legislative or regulatory battle will yield the result that ABC members would like. But having ABC of Metro Washington as their advocate will ensure that merit shop contractors have the chance to voice their point of view. Advocacy is one of the most important benefits that association members receive, said Jackson. “If these companies were to go out and hire their own lobbyists, it would cost them a lot of money. Through their membership, they get excellent services from our lobbying teams, plus we are all doing it together. We are the armor, the shield and sword in this battle, fighting on behalf of the industry.” n For questions and information about government affairs and advocacy, contact Marcus Jackson, ABC of Metro Washington director of government affairs: mjackson@abcmetrowashington.org; 301.595.9711 PART OF THE PROBLEM IN THE DISTRICT OF COLUMBIA IS THE SPEED AT WHICH A PROPOSAL CAN BECOME LAW.
