Silchester in Hampshire may not be as well known as some other Romano-British settlements, but it is nevertheless a site of considerable interest to heritage specialists.
The city began in the 1st century BC as Calleva, the pre-Roman homeland of the Atrebates tribe. After the Roman conquest in 43 AD, it grew rapidly and was renamed Calleva Atrebatum. It was abandoned in the 6th or 7th century but, unusually, it was not reoccupied in the medieval period. As a result, no further construction took place and its remains have lain largely undisturbed. Many of the perimeter walls survive, as do parts of the city amphitheatre. In fact, it stands as one of the best preserved Roman towns in Britain.

We are seeing growing demand for building surveys, roof inspection projects and associated 3D modelling work. A recent project in Lancaster illustrates the services we are increasingly being asked to provide.
Set close to the town centre, Cable Street is a stone-built property comprising 3, 4 and 5-bed student flats. Designed by Richard Gillow in 1759, the building has considerable heritage value, though it has been repeatedly modernised and upgraded to maximise its appeal to the student market.

Mott McDonald Bentley, Wessex Archaeology and the Environment Agency
In recent months, we’ve made a number of visits to York, where we’ve been conducting an extensive aerial survey of land adjacent to the River Ouse.
Following torrential rain and subsequent flooding in December 2015, the Environment Agency took the decision to review and improve flood defences involving the Foss Barrier. The barrier features a gate that can be closed to prevent rising waters in the Ouse from backing up into the River Foss and flooding parts of the city. However, in 2015, these measures had proven inadequate. Having devised an improvement plan, the Agency appointed Mott McDonald Bentley to deliver the necessary upgrades, which include fitting eight new, high capacity pumps and associated control systems.

Topographic surveys are widely used across the civil engineering and construction industries – on sites where it’s important to get a clear understanding of shape and contour. However, the traditional approach – using teams of surveyors to locate hundreds or thousands of points on a chart – presents a number of challenges that modern UAVs can address. Continue reading “Topographic Surveys Using UAV:”
City centre building inspections present their own special challenges. Busy roads and pavements, together with the close proximity of other buildings, mean that erecting scaffolding or mast-climbers can be inconvenient and obstructive; sometimes impossible. In such circumstances, the use of UAVs can represent a safe, quick and low cost alternative. Continue reading “Building Survey: 24 Mount St., Manchester”
55 miles off the coast of Grimsby, Hornsea Project Two is creating the world’s largest offshore wind-farm. The multibillion-pound scheme will see the installation of 300 turbines over an area five times the size of the city of Hull. Funded by a Danish energy company, the site will eventually deliver clean, sustainable power to around 1.8 million British homes. Continue reading “Archaeological Survey: Grimsby”
