Quick Answer: Excavation estimating software turns measured earthwork quantities into a priced bid. Compute cut volume in cubic yards, measure trench length and depth, size shoring area, and let the takeoff drive the estimate so you spend your hours on pricing, not counting.
Excavation sits in CSI Division 31, earthwork. The estimate has to cover every cubic yard of soil that moves on or off the site, every hour of machine time it takes to move it, and every stick of shoring that holds the cut open while the crew works. Done by hand that means scaling lengths off a plan, computing volumes by hand, and re keying the totals into a spreadsheet. Done with software it means the takeoff drives the estimate, and your hours go to deciding the crew and the production rate, not the arithmetic.
What Trade Specific Estimating Means
Excavation estimating is not a square foot takeoff. A trench cut is a volume, a basement excavation is a volume, and a finish grade is an area, and each one prices differently. Trade specific earthwork software understands the difference between cut and fill, between bank cubic yards and loose cubic yards, and between common soil, rock, and muck. It applies the swell factor when you load the truck and the shrink factor when you compact the backfill, so the haul count reflects the way the soil actually behaves, not a lineal foot that pretends dirt is dirt.
A real excavation estimate splits into four cost layers. Equipment, which is the excavator, the loader, the dozer, and the trucks, each priced by the hour or by the cubic yard moved. Labor, which is the operator and the ground crew, priced at the rate for the crew you actually run. Materials, which is the shoring, the geotextile, the aggregate backfill, and the hauling, each tied to the measured quantity. And overhead, which is the mobilization, the traffic control, and the dewatering. Software that does not split these layers gives you one muddy number you cannot defend when the general pushes back on the price.
What Good Software Does for This Trade
Good excavation estimating software reads your site plan and the profiles, computes the cut volume from the footprint and the depth, measures the trench length and width, sizes the shoring area in square feet, and reports the haul off in loose cubic yards after swell. It separates bank volume from loose volume so your truck count is real, and it separates cut from fill so you can see whether the job balances or you are buying or selling dirt.
On the pricing side it applies your equipment rate, your operator rate, and your trucking cost to the quantities, so the estimate rolls up the way you actually run the work. You see equipment, labor, materials, and overhead separately, and you can change one input, like the truck cycle time or the swell factor, and the whole bid reprices without rework. When the disposal site raises its tipping fee you change one number and the estimate updates.
Must Have Features
- Cut and fill volume: compute bank cubic yards from the footprint and the depth, and convert to loose cubic yards with the swell factor so the haul count is real.
- Trench takeoff: measure trench length and width and depth from the profiles, and compute the volume per segment, so you are not averaging the trench into one number.
- Shoring and trench safety: size the shoring area in square feet and roll up the trench box, the sheeting, or the sloped bench cost against it.
- Soil classification: separate common, rock, and muck, because each one digs at a different rate and hauls at a different density.
- Equipment and crew library: a production rate per machine per soil type, so the hours come from the rate and the volume, not from a guess.
- Haul and disposal tracking: truck count from the cycle time and the loose volume, plus the tipping fee, so the haul cost rolls up against the actual truck trips.
- Export to your bid format: push the estimate into your proposal or your schedule of values without re keying.
What to Watch Out For
Generic estimating tools that treat excavation as a square foot or a lineal foot miss the volume entirely. A two foot trench and a ten foot trench are both lineal feet, but the second moves five times the dirt and needs five times the truck trips. If your software does not compute volume from the depth you will underbid the deep cuts and overbid the shallow ones.
Watch for software that ignores swell and shrink. Bank dirt expands when you load it into the truck, and loose dirt settles when you compact it back. A job that looks balanced bank to bank can turn into a haul off or a borrow pit when you apply the factors. If your tool does not apply them you will bid a balanced job and deliver a money loser. Watch for tools that do not handle dewatering, rock removal, or unsuitable soil separately. These are the line items that make or break an earthwork bid, and if your estimate rolls them into one average cost you will not see the risk until the job is in the ground.
Watch for hidden cost in the data entry. If the software still makes you type every trench segment into a grid, you have saved nothing over a spreadsheet. The point of trade specific software is that the takeoff reads the plans and the estimate builds itself. Anything less is a calculator with a price column.
How CyanBuild Fits
CyanBuild reads your site plan and the profiles, computes the cut volume in cubic yards from the footprint and the depth, measures the trench length and width, sizes the shoring area in square feet, and reports the haul off in loose cubic yards after the swell factor. The quantities feed straight into the estimate, and you apply your equipment rate, your operator rate, your trucking cost, and your overhead and profit. Equipment, labor, materials, and overhead roll up separately so you can defend each line. Every quantity carries a confidence flag and ties back to the sheet it came from, so when the general asks where the volume came from you can show them.
CyanBuild does not replace your judgment. It replaces the hours you spend scaling lengths and computing volumes by hand. You still set the production rate, still decide the crew, still choose the profit based on the risk. The software does the part a machine can do, and leaves you the part that actually wins or loses the bid.
Putting It Together
Excavation estimating software should read the site plan and the profiles, compute the cut volume, apply the swell and shrink factors, size the shoring, and price the equipment, the labor, the materials, and the overhead separately. It should handle rock, muck, and dewatering as separate line items, and reprice the moment the truck cycle or the tipping fee moves. If your current tool still treats a trench as a lineal foot, you are underbidding the deep cuts and overbidding the shallow ones, and you will not know which until the job closes. CyanBuild was built to do the volume and the haul count for you, so you can spend your time on the crew and the rate.
