Four deadlines, four different jobs

A survey needs lines of sight along a boundary and nothing else — narrow corridors, no finish standard, and often no material handling at all. It is the cheapest of the four and the one most often over-specified.

A build needs a working surface: enough area for equipment and material, stumps dealt with where foundations and services go, and drainage that will not turn the site into a problem for the next trade.

A sale needs appearance. The buyer is judging the property from a walk and a set of photographs, which makes finish quality matter more than it otherwise would and makes the access approach worth more attention than the back corner.

A permit or programme deadline needs documentation as much as work — dates, extents and often photographs, because what has to be demonstrated is not just that it was done but what was done and where.

Why a deadline costs more

Flexible work absorbs weather. Deadline work cannot, so the contingency has to be paid for in some other form: a bigger machine, ground protection, a second crew, a staged sequence, or simply a price that reflects taking the risk.

The largest single cost driver is being forced into soft ground. Ground protection mats are the usual answer and they are neither cheap nor fast, but they are far cheaper than repairing a rutted site afterwards.

Staging, which is usually the cheapest answer

Many deadlines apply to only part of a property. Clearing the part that has to be done by the date, and leaving the rest for a good-conditions window, is nearly always cheaper than treating the whole job as urgent.

That requires saying which part is actually date-bound, which is a question worth asking yourself before asking a contractor.

What to bring to the first conversation

  • The date, and what happens if it is missed
  • Which part of the property the date actually applies to
  • What has to be true on that date — a sightline, a working surface, an appearance, or a record
  • Whether anyone else needs to work on the site before or after, and when
  • Any documentation the deadline requires, so it can be produced as the work happens
