How this Sage customer ditched spreadsheets for Sage Estimating to win more bids

With operations in Maryland and Virginia, general contractor W.M. Schlosser Construction Company is a recognized leader in the industry, known for its quality work, a culture of safety, and high employee retention rates.

Focusing exclusively on government work, the company tackles projects up to around $50 million in value, including water treatment plants, courthouses, prisons, and airports.

It’s a competitive market, and winning the fixed-price projects requires experience, industry knowledge, and a sharp pencil. W.M. Schlosser is not just winning projects, it is winning profitable projects, thanks in part to the highly accurate and efficient estimating process of Sage Estimating.

Precision accuracy

“I started working with Sage Estimating decades ago,” explains Jeff Binder, Estimator for W.M. Schlosser. “When I joined W. M. Schlosser, I encouraged the team here to implement it. Quite simply, Sage Estimating is the best estimating system available.”

With fixed-price government bids, the low bidder wins the project. But no contractor can survive if its projects are unprofitable, making accurate initial estimating critical. Sage Estimating allows W.M. Schlosser to build some of the most accurate estimates in the industry.

“Our accuracy is spot on,” says Jeff. “Our material cost estimate for a recent project was within $43 of the actual cost. And we’re consistently that good.”

Material pricing fluctuates wildly, so the company needs to adjust costs frequently. “Lumber is up 300% right now. With Sage Estimating, we can go to the lumber subtotal and triple the number,” explains Jeff. “The updated costs flow back through the line items of the estimate. It’s that easy. You can’t do that in Excel.”

Fast tools lead to more and better estimates

Accuracy is paramount, but speed is also essential, and speed is another area where Sage Estimating excels over spreadsheets. “An estimate that takes me four hours to complete in Excel takes me 20 minutes to complete in Sage Estimating,” says Jeff.

As a general contractor, W.M. Schlosser uses subcontractors to perform most of the trades. “But we estimate everything,” says Jeff. “By doing our own estimating, we can submit project bids more quickly.”

This in-house estimating capability proves exceedingly valuable as the building boom intensifies and subcontractors are slower in completing their own estimates. “Our estimates serve as a way to verify and validate the bids our subs turn in,” Jeff adds.

By estimating every trade on every project, the company gains a better understanding of the project and can answer any subcontractor question more quickly and accurately. This gives W.M. Schlosser multiple advantages. With better information, subcontractor bids are more accurate. The bids are often more competitive since there are fewer areas of uncertainty. And, in situations where there are just one or two subcontractors bidding, W.M. Schlosser’s estimate serves as a solid comparison to measure the other bids against.

“We’re able to work this efficiently because we can generate estimates so quickly in Sage Estimating,” says Jeff. “If we were working in spreadsheets, we wouldn’t be able to take the time to do it.”

Consistent, cohesive, and collaborative

Excel has been the de-facto estimating tool for many companies, primarily because it’s a tool familiar to most estimators. Sage Estimating leverages that familiarity, providing spreadsheet-style data entry that shortens the learning curve.

“Sage Estimating brings together the best of all worlds,” Jeff explains. “Electronic takeoff, cost, assembly and formula databases, and an intuitive spreadsheet-style data entry interface.”

By standardizing its estimating processes using Sage Estimating, W.M. Schlosser eliminated the separate, disjointed workflows previously relied on by the estimating team. “We had several estimators all creating spreadsheets that looked completely different, and sometimes they contained errors due to formulas getting changed or deleted,” adds Jeff. “With Sage Estimating, all the estimates are in the same format, which makes them much easier for our chief estimator to review, and they have zero mathematical errors.”

Companies with multiple estimators will realize compounding benefits, notes Jeff. “In Sage Estimating, you can have multiple estimators working on the same project, each handling a separate trade, for example. This creates a single, consistent project estimate that is completed more quickly, is easier to review, easier to collaborate on, and definitely more accurate.”

Put your trust where it’s earned

What would Jeff tell peers in the industry that aren’t yet using Sage Estimating? “I’d tell them their Excel estimates might not be as accurate as they think. I used to think my spreadsheets were the best thing on earth, but they weren’t. Excel estimating is error prone. It’s simply too easy to make common mistakes like putting a total in a unit price field or accidentally overwriting a formula. In this industry, too much depends on nailing the estimate to trust Excel. It’s better to put your trust in a product that has earned that trust.”
