What is Dimensional Control?

Dimensional Control Surveying is the technique and science whereby 3-Dimensional spaces are accurately measured to determine the area between points, creating digitally mapped distances and angles.

Dimensional Control surveying has been used for decades around the world in some of the largest shipbuilding and offshore fabrication facilities.

Dimensional control exists primarily because of safety, reducing the need for ‘hot work’, but also because it is highly accurate and saves time and costs during expensive shutdowns and maintenance periods.

What Our Customers Say

“I have been involved in piping fabrication for 30 years and the Wheatstone Jumper Spools Fabrication was the most challenging project that I have ever come across, in terms of complexity, tolerances and schedule, to the point where every joint needed to be surveyed by a surveyor and marked prior to cutting, again on fit up and then after welding all of which 3B Survey did an excellent job.

Considerable effort was put in by the 3B site team, with up to 8 full time surveyors, working 12 hours a day and 7 days a week over the life of the project.

We would have no hesitation in recommending their services and look forward to working with 3B Survey again in future.”
