Since works began in 2010, Aspect Land & Hydrographic Surveys Ltd has provided marine survey services to Scotland’s largest transport infrastructure project in modern times.

Playing a pivotal role in the pre-construction by supplying hydrographic and geophysical data for the initial design and engineering works, Aspect were retained by several JV partners to provide real-time data sets during both dredging and rock blasting phases and early constructions works.

As works progress, innovative solutions were required to conduct surveys within previously unimaginable environments and ensure works continued to agree timescales.

Thereafter, the Government body overseeing the works required bi-annual periodic monitor surveys to be conducted to ensure the integrity of the surrounding marine environment was not adversely affected by the structure, a programme required over a 10 year period.

With over 42,000 tonnes of steel used on this project, Aspect Land & Hydrographic Surveys Ltd are proud to be associated with the longest three tower cable-stayed bridge in the world.
