Timber Frame - measuring the wall plate

[Lincolnshire Ian]

We are instructing groundworkers to construct the wallplate which will accept our timber frame building. The tolerances on the wallplate are understandably very tight, 5mm over 8m.

So that I can sleep at night I will want to check the measurements myself, and a standard tape measure feels inadequate for these types of measurements. 

How can I get a super-accurate measurement? 

Many thanks

A normal branded steel tape should be fine.  If your longest measurement is 8.0m the 2 pack Stanley ones from Screwfix a decent value and give you +-2mm over 8 m.  Height is simple with a decent rotating laser level.

Do it yourself 

Ground workers won’t be accurate
