Drainage

Beginnings of our dig for a 9m deep pumping station. Had to plan a multi stage dig to allow the excavator to reach the bottom. One of the very few times I worked on a dig where it was below sea level. Water management was certainly an interesting challenge.

Accurate line and level was important here as each manhole was few and far between.

Frequent monitoring of drainage is key to ensure the line is not veering off track and is being laid to the correct grade.

This culvert had to be installed to feed one swale to the next. The whole project was 1km long! Level checks were important here as the fall from one field to the next was marginal to say the least!

Getting the initial dig and blinding level right is critical to avoid the crates being installed too high or too low causing unwanted clashes further along the build.

Accurate setting was important to get the foundation of this tank right as I had to work backwards from the invert level of the inlet + outlet and ensure when the concrete was placed that the invert levels matched that of the design levels
