Formula Used
The calculator first converts chase size from cubic inches into cubic feet.
It multiplies length, width, and depth, then divides by 1,728.
Total volume equals volume per chase multiplied by chase count.
Waste adjusted volume equals total volume multiplied by one plus waste percentage.
Material cost equals adjusted volume multiplied by material rate.
Labor hours equal total volume divided by productivity.
Labor cost equals labor hours multiplied by labor rate.
Direct cost equals material, labor, equipment, and permit costs.
Overhead is added as a percentage of direct cost.
Profit is applied after overhead.
Final estimate equals direct cost, overhead, and profit.
Chase the Craft Calculator for Construction Planning
Purpose of the Calculator
A chase is a planned passage in a wall, floor, or ceiling.
It can carry pipes, ducts, cables, or conduit.
Poor chase planning can create delays.
It can also waste labor and material.
This calculator gives a structured estimate before field work begins.
It helps builders compare size, count, labor, waste, and markup.
The goal is not only cost control.
It also supports cleaner coordination between trades.
Why Chase Estimating Matters
Construction crews often price chases from rough notes.
That method can miss volume, access limits, and patching effort.
A measured approach gives better budget control.
It also reduces confusion during bidding.
When length, width, and depth are entered, the tool finds volume.
Then it adjusts volume for waste.
Labor is based on productivity.
This makes the result useful for planning and review.
Cost Control Benefits
The calculator separates material cost from labor cost.
It also includes equipment, permit, overhead, and profit.
This helps estimators see where money is going.
If labor is too high, productivity can be reviewed.
If material cost grows, waste can be checked.
This level of detail is helpful for remodels, service upgrades, and commercial fit-outs.
It also supports change order pricing.
Field Use and Review
The result should be checked against site conditions.
Wall type, embedded steel, access, dust control, and patching can affect pricing.
Use the estimate as a planning baseline.
Then adjust it for crew skill and project risk.
The CSV and PDF options help save records.
They also make sharing easier with supervisors or clients.
For best results, measure carefully.
Keep units consistent.
Review each input before approving the final number.
Good estimating protects margins.
It also improves scheduling, coordination, and site readiness for every crew.
FAQs
What does this calculator estimate?
It estimates chase volume, material cost, labor hours, overhead, profit, and final cost. It is useful for construction planning and pricing.
What unit should I use for chase size?
Enter length, width, and depth in inches. The calculator converts cubic inches into cubic feet for costing.
What is productivity in this calculator?
Productivity means cubic feet completed per labor hour. A higher value lowers estimated labor hours and labor cost.
Why is waste percentage included?
Waste covers material loss, cutting errors, patching variation, and handling issues. It helps create a safer estimate.
Can I use this for remodeling projects?
Yes. It works well for remodels, utility upgrades, and service routing. Always adjust inputs for access and wall conditions.
Does the result include profit?
Yes. Profit is added after direct cost and overhead. You can set the profit percentage based on your pricing policy.
Can I export the estimate?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for a simple printable report.
Is this suitable for final bidding?
It can support bidding, but final prices need site review. Check drawings, trade coordination, access, and local labor rates.
