Because the software allows her to recalculate easily, Malik does precisely that, often finding a better, cheaper way to do the job. “I like to value-engineer it: What if I raise the grade here, et cetera. Most engineers won’t take cost into account, but I do. There was a recent project building eight senior family units, and not all buildings had full basements. I found that if the builder changed the cut-and-fill areas, maybe that was a cheaper way to do it. I like to look at projects differently, because now I don’t have to recalculate it all by hand. If I change the grades a bit, do I have to haul as much away? With EarthWorks, I can look at five different scenarios in 10 minutes!”

Once she knows how much soil is on a site, and how to move it, Malik makes her estimate. “EarthWorks gives me a takeoff, then I put that data in my own program, made of Excel, to do the estimate. I input work crews’ costs, et cetera, and then I know how much it will cost to put in so much pipe, plus how much our equipment costs.”

How does she know the estimates for equipment, such as how much diesel fuel is used per hour? “We have Komatsu equipment, which has a computerized feature called Komtrax; it sends data to my computer, telling me how much diesel is in the machine, and it tracks the hours of use. With Komtrax you can also see if the machine is working too hard—maybe I should send out a bigger machine?

“This tracking allows us to see how are we performing versus how we estimated: What was the weather? Was it raining? Who was on the site? I can find out the answers as to why the job isn’t going per estimate. Maybe we can’t do 250 linear feet of pipe per day; we only do 220. Having all this information makes me a better estimator.”

Malik also uses EarthWorks when invoicing the customer. “As we bill by cubic yards of earth moved, my foreman tells me, ‘This is the area that was done.’ I take the original EarthWorks takeoffs, mark the perimeter, and it calculates the cubic yards moved. I don’t know if they designed it for that purpose, but that’s how I do it, so I know how to bill.”

OS Excavating also uses Trakware’s TrenchWorks program. “I love it even more than EarthWorks,” Malik says. “We’re not always just digging; a big part of our business is installing pipelines, and those are never a perfect, straight line. With TrenchWorks, first you get a bird’s-eye view: lines across the blueprint. Then you can look at the profile, which gives you all the clues of the job. Sometimes the pipes we put in will cross another line—sewer or water—and usually you have to truck in all the backfill materials. TrenchWorks will tell me how many tons I’ll need.

“For example, from bird’s-eye view, you see 1,000 feet of water line, dug at an average depth of 4 to 5 feet. To find how much backfill I need was tedious, especially if it’s done by hand or in Excel. Between the TrenchWorks digitizer and my inputting of the pipe and backfill material, the program will break down the actual figures for you. Like: So much of this pipe is laid at 2 to 4 feet; this much is set at 4 to 5 feet. TrenchWorks gives you a very accurate bedding and backfill quantity—if you input the data correctly, of course. If you were to hand-calculate, you’d have to rely on average depths, which will never be as accurate. With TrenchWorks, what used to take me 20 hours I can now do in five.”

Malik thinks almost anyone in the business can use Trakware’s products. “So many people are good at what they do, but not good at computers. However, EarthWorks is so simple. I can use the computer, but I don’t want to work so hard with the program. I want it to be simple, and EarthWorks is.”

Despite all the information these programs put at her fingertips, are there still unforeseen tie-ups on a site? “If we find protected species on the site, all work has to stop so we can report it,” she concludes.

Ron DiFuria, general manager of Dudley Construction Co. Inc. in Fort Wright, KY, also uses Trakware’s EarthWorks. “Before we had the program, I did takeoffs by hand. What used to take me 10 hours, now I can do in 20 minutes, especially when I import CAD drawings e-mailed from designers. It’s really great: Changes are much easier with the software. In the old days, it’d take a day to do the takeoff.”

DiFuria’s computer has a digitizing tablet, but “I try do most by CAD. Now EarthWorks also allows you to take it from a TIFF or PDF file, as long as the PDF hasn’t been artificially reduced. EarthWorks can read the drawings’ scale by the DPIs. What I like about EarthWorks is that I can zoom in and make sure I’m getting the right items on the drawings. I think the tablet takes much longer; sometimes people still send me drawings, and I have to trace them. I like the CAD feature better.”

EarthWorks not only calculates the total site, but it also will put the phases together, he says. “I get several sheets from a project, or different CADS. I can merge all those together on one screen and then break the project down in as many phases as needed. But the program won’t tell you the logic of the breakdown. No software will. That’s something you get from experience. If I do make an error when using the digitizer, if I have the computer’s speakers turned on, it will tell me the elevations.”

Dudley Construction is a site developer. “We don’t build structures. We do site clearing, excavation, and utilities. I need to know how much soil has to be moved.

“I use an Excel file for costing, but I take the figures from EarthWorks to make estimates. I can print out a color grid map—red is cut, blue is fill—it helps me ‘sell’ my jobs. I can tell the designer, ‘This is how I’m going to do it.’ Or I can give him a 3D map showing the contours of the site. If I’m looking at an unbalanced job—meaning, you have to take dirt away as well as bring it in—the program will help balance the job by showing how this soil can be moved and reused.” Balancing the site can save money, although “Pricing has a lot to do with the terrain you’re working in and the fuel efficiency of your machines.”

DiFuria loves the program. “I’ve used three other such programs, and EarthWorks is simpler to use. You can’t beat the accuracy, and the support Gregg [LaPore, Trakware’s owner] gives you. In the past, I’ve sent him a file, asking, ‘Why is this taking so long?’ That file took overnight to calculate. As it turned out, the designer had two files overlaid on each other, and the computer was calculating it twice! Trakware is always adding something to its software; that’s why I’m a beta tester for the company. I’ve recommended it to three other contractors in this area.”
