Since space is scarce and each inch of land has a function read here, underpinning in the city becomes an art. In the hustle and bustle of urban living, you need to be able to work with your hands. Come and explore the complexities, problems, and challenges of underpinning for densely populated locations.
Imagine subsoiling a century-old apartment building downtown. Small streets with heavy traffic make the neighbors nervous. What’s our aim? Stabilize a building without causing disturbances. Walking the highwire without a net requires precision, organization, as well as innovative problem-solving.
First we have to deal with the space issue. Urban areas do not have many large construction sites. We can’t just dig out the foundation and stop. Mini-piles, compact underpinning and other methods are used to fit into tight spaces. As in a phone box, every movement must be careful and subtle to avoid disturbing others.
Noise is another important issue. The urban environment is busy and no one wants construction that sounds loud. We use quieter resin injection underpinning. A high density epoxy is injected in the earth. It expands and hardens, stabilizing the foundation with the least amount of noise and vibration. It’s a little like adding a secret part that doesn’t get noticed, so we don’t become the alarm clock of the city.
Traffic management complicates things. We cannot shut down city highways to build. Juggling involves working closely with local officials to regulate traffic, ensure timely deliveries, and ensure pedestrian security. Imagine a circus tent set up in Times Square, during rush-hour.
Utility issues are a second dilemma. In every city street, there is a network that’s vital to the operation of the city. A precise mapping of these utilities is vital. GPR technology detects and maps these hidden barriers. It’s similar to x ray vision and reveals what lies beneath the surface without having dig up half the town. It prevents interruptions of key services. We can fortify the buildings while maintaining city functions.
