This costs a fire door survey before it is commissioned. Enter the doors to survey, the survey minutes per door, the floors to walk and the minutes per floor, the surveyor's loaded hourly rate, the report writing hours and the share of doors not accessed on the day, and the page returns the survey hours on site, the cost including the report, the cost per door, the doors to revisit and the surveyor days. A survey is a quote with a per-door figure hidden in it; the page shows it.
Minutes per door is the price
Fifteen minutes per door is a survey that looks at the leaf, the frame, the seals, the closer, the gaps, the glazing and the certificate and photographs them; five minutes is a walk-past. The page prices whatever figure you set so the quote is compared on the same basis, and the cost per door it prints is the figure to hold a surveyor's quote against.
Floors and access are the hidden hours
A tower is a lot of lifts and a lot of knocking. The minutes per floor and the share of doors not accessed on the day are the two inputs that turn a neat per-door estimate into a real one, and the page counts the doors to revisit at your access rate so the second visit is in the price rather than a surprise.
The report is part of the survey
A survey without a report is a walk. Four hours of report writing at the surveyor's rate is part of the cost, and the page includes it in the total and in the cost per door, because the report is what becomes the register every later check runs on.
Fire door survey cost calculator: common questions
Is this a free fire door survey cost calculator?
Yes: the hours, the cost, the cost per door, the revisits and the days are computed here for free with no account, and you can print the plan. DoorsetBook Pro saves the costed survey against the building and files the completed survey as the first record on every door.
Should the survey be done in house or bought in?
Put your own rate in for one and a surveyor's quoted rate for the other and compare the cost per door the page prints. What the survey needs either way is a competent person and a record per door.
How many doors will be missed on the day?
As many as your access rate says. Flat entrance doors need the resident in; the page prints the revisits at the share you set, and Pro keeps the evidence of the attempt against each door.
