Case Study: Putting Take-Off To The Test

When KBE Building Corporation started work on a new elementary school in Waterbury, Conn., in 2010, the firm was immediately confronted with some significant challenges.

The Farmington, Conn., general contractor, founded in 1959, was serving as the construction manager on the $20 million project to build a new facility for Carrington Elementary School. But the new facility had to be constructed at a higher elevation than the current school building, and it also had to be built while school was in session—without disrupting the school day or jeopardizing the safety of students. The existing facility was scheduled to be demolished upon completion of the new school.

KBE needed to create an entrance road that not only accommodated the existing school, but it also needed to integrate the elevation and steep slopes behind the school, 40-foot tall retaining walls and rock removal with minimal impact to earthwork.

Dale Cote, senior estimator and site specialist for KBE, set off to find a solution for these challenges during the early conceptual phase. Armed with little information about the plans, just conceptual site layouts in PDF format, Cote turned to InSite Software to help him analyze the layouts.

Cote says he was first introduced to InSite’s SiteWork Software when he started at KBE eight years ago, since that was the software the firm was using at the time.

“The company gave me the option to use whatever I wanted when I first started,” he says. “I looked at several other pieces of software and decided to stick with InSite.”

InSite SiteWork helps users calculate earthwork and utility quantities, according to Steve Warfle, product manager for InSite Software. With the program, Warfle says estimators can enter existing and proposed contours, spot elevations and sloping lines to define the existing and proposed surfaces. Stripping areas are used to track topsoil and other underground strata as well as demolition quantities. Stripping depths for various designated areas can be controlled either by simple depth or by strata depths given by soil borings. Subgrade areas are used to itemize cut/fill for any designated areas and to determine structural and nonstructural fill requirements, including topsoil replacement. The trench feature provides excavation and backfill requirements, cut depth brackets for trenches and pipe length measurements. The software can be used with any combination of image files (PDF, TIF, JPG), vector PDF (firstgeneration PDF) files and CAD files (DWG, DXF).

One of the reasons Cote says he likes InSite is because of the user-friendliness of the software.

“It’s like it was designed by people who were earthwork estimators,” Cote says. “I could relate to it a lot easier.” In less than a week, Cote says he was confident he was producing files that were accurate.

When it came to the school project, which included about $5 million in site work, Cote says he used InSite SiteWork with 3D Live to demonstrate critical details of the job to help the project team visualize the work that needed to be done.

One of the critical details was determining the entrance road placement.

“We could’ve entered the school on the left or right,” Cote says. “Using InSite to do my own grading plan, I was able to figure out what each of the options were. The deciding factor was the angle for turning the buses and the cost factor.”

Another benefit of the software is its 3D Live feature, Cote says. Warfle says this feature allows estimators to view existing, proposed and subgrade surfaces in a separate window in highresolution 3D, each time a contour, spot elevation or subgrade is entered. Changes are instantly updated in the 3D model, allowing users to easily spot mistakes in the plans so corrections can be made, he says.

“It has a certain wow factor when you whip [the layout] out in 3D and compare and show the different options all at once,” Cote says. “It can be as though you’re actually looking at the site as how you want to make it.”

Cote says he’s also received excellent support from the InSite team when he’s had questions or run into problems.

“Whenever I call, they’re right there to walk you through answer,” he says. “When you talk to them on the phone, it’s not like you’re talking to a tech guy; it’s like you’re talking to someone who does earthwork.”

While all the features of the software are helpful, Cote says the true benefits of InSite SiteWork are its accuracy and time-saving tools. Cote says it only takes him three days to accurately build files, instead of the six days it used to take him.

KBE used InSite Software throughout the school project, which is currently in the earthwork operations phase. The firm has also used the software on other major projects, including a $10 million design-build project for the Army Reserves in Middletown, Conn.

Cote says he’d encourage other contractors to see what benefits InSite could provide them.

“Give the demo version a try,” he says. “The support is great. The software is easy to use, and it’s accurate. I know I always can use InSite tools to help visually show everyone where they’re headed.”
