Joinery that must fit a space.
WHY IT DIFFERS FROM FREESTANDING WORK
It must fit a space that is rarely square, level or plumb.
WHAT TO ESTABLISH ON SITE
Dimensions at several points Whether walls are plumb and square Whether floors are level Where services run What obstructions exist
WHY AT SEVERAL POINTS
Openings vary across their height and width, and the smallest dimension governs.
WHAT TO MEASURE
The smallest dimension, and build to it.
WHAT TO ALLOW
Scribing margin against walls.
WHY
Units built to exact dimensions cannot be fitted into imperfect openings.
WHAT TO ESTABLISH ABOUT SERVICES
Where cables, pipes and sockets are.
WHY
Fixing into a concealed service is dangerous and expensive.
WHAT TO ESTABLISH ABOUT THE PROGRAMME
When the space will be ready What other trades must complete first When you can install
WHY IT MATTERS
Installing before plastering, painting or flooring produces damage and rework.
WHAT TO AGREE
The point at which the space is ready.
WHAT TO DOCUMENT
Site conditions, with photographs and measurements.
WHAT TO RE-MEASURE
Before manufacture, if time has passed or other work has occurred.
WHY
Dimensions change when other trades work.
WHAT TO ESTABLISH ABOUT ACCESS
Whether the finished units can physically be brought in.
WHY
Assembled units that cannot pass through doors or stairs are a total loss.
WHAT TO PLAN
Assembly on site, where access demands it.
