We were instructed by Marmus, a consulting marine engineering company, to undertake a detailed survey of a piece of land next to the River Crouch in Essex. The purpose of the survey was to assist with the design of a new spoil jetty. The spoil jetty will allow barges full of soil from the Thames Tideway project to unload their material and spread it throughout the area to help build up the land. The project is quite important as the soil needs a home after the tunnelling works, and it helps improve the area’s flood defences as the land and embankments can be built higher.
The site itself was relatively isolated and required a lot of walking with equipment to get to the area in question. The lack of vegetation and trees on the site helped our surveyors as there were no blocked site lines to go around! The survey did require one of our surveyors to trudge around the muddy foreshore to take spot height levels, which had to be carefully planned with safety in mind – life jackets were a must!
The area was surveyed relatively quickly; it took six hours from start to finish. Once we returned to the office we drew up the survey and produced a site plan of the area. We were then tasked with taking a number of sections through the site to establish the best locations for the potential spoil jetty. Our drawings helped decide an appropriate location based on the levels of the ground, objects in the way and the hydrography of the river.
