Surveying & Mapping Experts
26 YEARS RUNNING
Our Story
Established in 2000 in the Sultanate of Oman, Nusail Engineering Consultancy has been delivering professional surveying, mapping and engineering consultancy services for 26 years. From our Oman base, we have expanded our operations to support projects across the UK and Saudi Arabia, serving infrastructure, marine, construction, environmental and development sectors.
Our expertise includes 3D laser scanning surveys, aerial surveying and geo-mapping, UAV LiDAR surveys, topographic surveys, land surveying, hydrographic and bathymetric surveys, Geographic Information Systems (GIS), highway engineering, road engineering and geotechnical engineering support. We combine practical field experience with modern survey technology to provide accurate, reliable and cost-effective project solutions.
For more than 26 years, our objective has remained the same: to exceed client expectations through professional service, prompt project delivery, technical accuracy and flexible support. With Nusail Engineering Consultancy as your survey and mapping partner, your projects are handled by an experienced team with strong regional knowledge and international capability.
