Freeman’s Reach Phase 1 and 2

Project Overview

Rainton Construction was appointed to undertake Phase 1 and 2 civil engineering and groundwork packages for Freeman’s Reach. The overall development provides high-quality, eco-friendly offices, as well as retail and leisure accommodation.

Our in-house team undertook the surfacing, and Tynedale Roadstone provided the material.

Scope of Works

Phase 1

Construction of a concrete channel in the River Wear to house a 13-metre long, 20-tonne Archimedean Screw for hydro-power generation on the site (the first UK city centre development to do so).

Works also included:

• Construction of a fish pass, otter hotel, bat cave and Sand martin nest sites
• Foundations
• Drainage
• Retaining walls
• Capping beam system
• Ground and upper floor slabs
• Hard landscaping
• Installation of street furniture

Phase 2

The scope of works was as follows:

• Substructures and foundations.
• Upper, first and second-floor slabs
• Below-ground drainage and service trenches
• Hard landscaping
• Piling mat
• Off-site disposal of excavated material
• Construction of steps and retaining walls and installation of street furniture

Challenges

Situated adjacent to Durham Cathedral and Castle, a UNESCO World Heritage Site, and near the River Wear, Milburngate Road bridge, and footbridge, this project faced unique constraints due to its sensitive location and proximity to commercial and residential areas. The original scope of work underwent significant changes, demanding exceptional logistical flexibility from Rainton Construction to adapt work methods as the project progressed.

The excavation and concrete channel works involved constructing a challenging 15m deep excavation in weak alluvial soil for a reinforced concrete turbine chamber and spillway. The location posed significant risks, necessitating meticulous attention to detail, careful planning, and transparent communication with the project team.

Summary

This project was completed on time and within budget, to the satisfaction of the client. Rainton Construction was awarded the ‘Project of the Year’ in the Civil Engineering Contractors Association (CECA) North East Awards 2015 for our work on Phase 1 of this project.

We are proud to have supported a high-profile sustainable development integral to the Durham Riverside Renewal.
