Site Records and Drawings:- The default presentation of results is using neatly, hand annotated Site Record Sheets and pro-forma, for recording observations, test data and details gathered on site, with either neat hand-drawn sketches, or Client supplied AutoCAD outlines, annotated by hand, with standardised schedules of dilapidations and defects, neatly annotated by hand.
Unless specifically requested, we will not re-process these documents further.
Dimensional Measurement:- Is undertaken as an inherent part of many of our activities and although all dimensions recorded should be taken as ‘approximate’, every effort will be made to ensure the precision and accuracy of the approximations.
All dimensional measurements less than, ‘nominally’, 300mm, e.g. where checking reinforcement bar diameters, measuring depths of drilling (dust samples and cores), measuring depths of carbonation, or measuring small defects etc., will be measured using calibrated steel rules, manufactured to EU Class I. Where steel rules will not fit, e.g. within small breakouts etc., either calibrated callipers or engineers dividers will be employed, with dimensions transferred from a calibrated steel rule manufactured to EU Class I. We will generally round such measurements to the nearest whole mm. However, if more accurate dimensional data is required, this can be accommodated, but using alternative, bespoke, methods.
All dimensional measurements greater than, ‘nominally’, 300mm, e.g. where measuring larger defect sizes or structural dimensions, will be undertaken using measuring tapes manufactured to EU Class I. We will again generally round such measurements to the nearest whole mm. However, if more accurate dimensional data is required, this can be accommodated, but using alternative, bespoke, methods.
NB: The condition of the steel rules, callipers, measuring tapes, and engineer’s dividers will be checked prior to every shift / measurement and only used if in good condition, i.e. the ends / edges / points are straight, sharp and undamaged, with the gradations / values / markings clearly legible.
Measurements of Temperature:- Ambient air and surface temperature can have a direct effect on at least some of the measurements undertaken and can also affect the operation of some of the equipment used. Although the effects are generally relatively small, temperature measurement will be undertaken, where appropriate, using ‘simple’ liquid filled thermometers, to ensure that the effects are fully understood and accounted for. Although, all recorded temperature measurements should be taken as ‘approximate’, to the nearest 10C, every effort will be made to ensure the precision and accuracy of the approximations, as follows.
At least annually, or more often if measurements are suspected, or the thermometer has been used under extreme conditions, or dropped / otherwise mishandled, each thermometer will be checked for accuracy using both iced water and hot water methods.
