Network protection wall and footing 2021

November 2021

For this particular project, I had to go through various compliance measures to make sure my work followed stringent industry standards. This was completed on time and within budget. It’s a great example of my dedication to deliver a quality product and see it through from start to finish despite complications in order to ensure full client satisfaction.

Retaining wall construction

September 2020

While working on this project, I was very strict about the materials and footprint of my work. My client was interested in an economically and environmentally sustainable outcome due to location, I did everything to respect these wishes throughout the whole process in order to make sure they were satisfied with the outcome.
