A Budgeting Guide for Site Development
Site development is one of the biggest line items in any construction project, and it is the one people underbudget the most. It is also the part that happens first, so when it runs over, it throws off everything after it. On a typical job, sitework runs somewhere around 15 to 25 percent of the total project budget. Here is how to think about that number so it does not surprise you halfway through.
Break the sitework into its real parts
The mistake is treating site development as one lump number. It is not. It is a stack of separate jobs, and a real budget prices each one: clearing and demolition to get the lot ready, earthwork and grading to shape it, fill dirt where you have to build the ground up, the building pad and compaction, stormwater and drainage, erosion control, and access like driveways or roads. Lump it all into one line and you will miss something. Itemize it and you can see where the money actually goes.
Know what moves each number
Every one of those line items has its own cost drivers. Clearing depends on how wooded the lot is. Earthwork depends on how much dirt has to move and how far. Fill depends on how much you need and how far it is hauled, which is where owning a pit helps. Stormwater depends on what the county and the water management district require. The more the estimate spells out quantities and methods instead of round numbers, the more accurate your budget is and the fewer surprises you get.
Build in a contingency
No matter how good the estimate is, the ground has the final say. You hit soft soil that has to come out, or rock you did not expect, or a wet season that stalls the work. A smart sitework budget carries a contingency for that, usually a percentage on top of the estimate, so an honest surprise does not blow the whole job. The contractors who do not budget a contingency are the ones writing change orders later.
Why a detailed estimate beats a cheap one
The lowest bid is not the cheapest job if it is vague. A proposal that says site grading as needed is an invitation to change orders. One that spells out the acreage, the slopes, the compaction standard, and the quantities tells you exactly what you are buying, and it protects you when conditions change. Detail up front is what keeps the final number close to the bid number. That is the whole point of budgeting the work right.
