Erith Contractors – 15 Bishopsgate, London

Project Value: £250,000
Client: Erith Contractors
Location: Tower 42 Estate, London

Project Overview

Located within the prestigious Tower 42 Estate, 15 Bishopsgate was a high-quality mixed-use redevelopment project that replaced and expanded the existing accommodation while enhancing the surrounding public realm.

The scheme delivered a six-storey office building with retail space at ground and basement levels, forming part of the re-landscaped public areas and modernised estate environment.

Our involvement focused heavily on the enabling works phase, where precision and vibration control were critical due to the sensitive nature of the surrounding occupied buildings.

The Challenge

Working in a busy central London location presented several key challenges:

• Protecting adjacent existing structures
• Maintaining extremely low vibration levels
• Operating within restricted access zones
• Cutting through 800mm deep heavily reinforced concrete
• Avoiding traditional heavy breakout methods

Because of the environment and structural sensitivity, conventional demolition techniques were not suitable.

Our Specialist Approach

To ensure safe, controlled, and precise execution, we adopted advanced cutting solutions:

Track & Wire Sawing

Areas that would typically be broken out using heavy machinery were instead
track and wire sawn into manageable sections, allowing for controlled removal and minimal disruption.

Inverted Track Sawing

Due to access constraints, inverted track sawing was implemented to safely operate within confined areas while maintaining cutting accuracy.

On-Site Equipment Strategy

To maintain efficiency and flexibility, we kept:

• 2 Track Saws permanently on-site
• 1 Wire Saw permanently on-site

This ensured we could respond immediately to last-minute changes or additional cutting requirements without delaying the programme.

The Result

• Smooth and efficient enabling works
• Minimal vibration impact to surrounding structures
• Successful cutting of deep reinforced concrete
• High precision delivery in a complex urban setting
• Strong client satisfaction

This project demonstrates our capability in delivering specialist concrete cutting and enabling works in sensitive, high-profile London developments while maintaining the highest standards of safety and precision.
