Checking the access before writing the method
Basement clearances in older CBD buildings are unforgiving and often lower than a modern van. A ride-on machine that would suit a large basement floor is irrelevant if it arrives on a truck that cannot enter the ramp, and hiring a smaller delivery vehicle is not always possible for heavier equipment. The sequence therefore has to be access first, method second. Buildings rarely publish these figures, so the only reliable source is a tape measure.
Measuring properly means the ramp clearance at its lowest point, the internal door heights, any beam crossing the drive aisle, and the goods lift dimensions if the equipment has to travel between levels. Those figures take ten minutes to collect and they prevent a proposal that cannot be honoured. They also tell the building something useful about what any contractor can bring in. They also help the building answer the same question when another contractor asks it.
