Once planning permission is obtained and your Architect/Engineer has completed the design of your project the next step is setting-out. This involves marking-out positions of main structural elements from the design onto the ground, usually steelwork gridlines, external building lines, foundations, construction offsets, drainage positions etc.
With suitable construction drawings and site control we can achieve millimetre (approx. 1-2mm) accuracy where required. Datum Surveying has many years of setting-out experience ranging from simple house extensions to extremely complicated steelwork gridlines and large scale civil engineering projects.
Setting out is an ever changing process and involves on-the-fly calculations so as not to hold-up any construction work. Our engineers are connected via broadband, GPRS and mobile phone giving us the ability to transfer re-designs and survey information straight onto their laptops. If it is found that a survey is needed before setting out can commence i.e. to re-establish control stations to a local grid, our surveyors can process survey data, draw up, issue drawings and perform any calculations on-site keeping any delays to an absolute minimum.
Our total stations and GPS always book the final set-out position of any feature which along with our on-site internet connection allows us to forward the client a set-out check file before leaving site to confirm their acceptance of our tolerances.
"Datum Surveying Services Ltd. were employed to carry out all of our setting out and surveying requirements on our latest project at Markham Vale. They provided a highly accurate and reliable service in tough conditions and we look forward to using their services on our next projects."
