Advanced Basement Construction Methods and Engineering Expertise
At MJ Rooney, technology plays a central role in delivering safe, efficient and high quality basement construction. We develop a 4D model for every project, allowing us to plan and visualise how the structure and surrounding environment will change over time. This approach helps us identify potential risks early, refine construction methods and ensure complex basement works, particularly those beneath existing buildings, are carefully managed. We also use this technology to design temporary works schemes and navigate the party wall process with greater accuracy and efficiency. Our commitment to innovation has been recognised with awards including “Digital Construction Excellence” by Construction News, as well as "UK Technology Champion" and "Design Innovator" by New Civil Engineer.
