Timber Frame Project Timeline Estimator
This estimator forecasts the working duration of a timber framing scope from total framed area, expected daily production per crew, the number of parallel crews, and an explicit allowance for delay days. It is intended for preliminary schedules and scenario comparisons where a square-foot production rate is an appropriate summary of the planned framing work.
The output separates calculated production days from the added delay allowance. That makes the schedule basis easier to review than burying contingency inside the productivity rate. The estimate does not sequence floors, walls, roofs, inspections, deliveries, crane access, or predecessor trades, and it does not convert working days to calendar dates. Use a daily rate based on a comparable scope and then reconcile the result with the actual project calendar and constraints.

Formula
Production days = Total framing area / (Daily production per crew × Crews); Total working days = Production days + Delay allowanceWhere:
- Total framing area = scope in square feet.
- Daily production per crew = expected square feet completed by one crew per working day.
- Crews = crews able to operate in parallel.
- Delay allowance = additional working days entered separately.
Assumptions: Production scales linearly with crew count and the same area definition is used for both scope and rate. Shared cranes, limited work fronts, inspections, and delivery constraints are not modeled.
What the result means
Use the output as a project-planning estimate based on the values and assumptions entered above.
Actual field requirements can differ because project conditions, specifications, sequencing, and execution methods vary.
Given: 24,000 sq ft, 1,600 sq ft/day per crew, 2 crews, and 1.5 delay days.
Calculation: Combined capacity = 1,600 × 2 = 3,200 sq ft/day. Production days = 24,000 ÷ 3,200 = 7.5 days. Total = 7.5 + 1.5 = 9.0 days.
Result: 9.0 estimated working days.
Interpretation: The scope requires 7.5 production days at the stated rate, plus 1.5 working days of explicit allowance.
Are the results calendar days?
No. They are working days. Apply the project workweek, holidays, and shutdown periods separately when converting the duration into dates.
Can two framing crews always produce twice as much as one?
Not necessarily. Limited staging space, shared lifting equipment, inspection hold points, or a single work front can reduce the benefit of adding crews.
Should the daily rate include breaks and normal setup?
Yes if it is an observed full-day production rate. The rate should represent the same working-day definition you intend to schedule.
Where do weather delays belong?
Use the delay allowance for a simple explicit working-day provision. For seasonal or probability-based weather planning, use a more detailed scheduling method.
What if wall and roof framing have different rates?
Estimate them as separate phases with their own areas and daily rates. Combining dissimilar work into one average can hide schedule risk.
