Carriageway realignment, associated drainage, road planing and resurfacing works
Derek Lewis are pleased to announce their involvement on the Marketplace Roundabout, which is situated in at the heart of Doncaster Town Centre on the A630 and adjacent to the Doncaster College Hub. The Hub opened in September 2006 and provides further and higher education for over 13,000 part and full time students and helps individuals fulfil learning needs for the local and wider economy. The Marketplace Roundabout is connected to St. George’s Bridge, which is the gateway to the major road links of M62, A1M and M1 connecting the cities of the Northern Powerhouse with the rest of the UK.
Alongside the contracted works the nature of the contract and location involved Derek Lewis Ltd delivering solutions to overcome a number of hazards and circumstances which were unique to the contract. For example; Chapel drive had to remain open, particularly on Thursday evenings due to a high volume of people attending college events. In addition, it was specified by the client that the roundabout was to remain partially open in all directions at all times whilst surfacing work were carried out. Fulfilling these requirements meant that Derek Lewis called upon the full spectrum of their expertise in order to control the environment and minimise the risks of noise, dust, vibration, dirt and other debris to site operatives, members of the general public, adjoining land and building occupiers.
Works to The Marketplace Roundabout & Chapple Drive started on the 28th September 2015 and was scheduled to last 3 weeks. Due to the location of the roundabout and its importance to Doncaster, the surfacing work needed to be carried out between the hours of 19.30-06.00, thereby allowing Doncaster to operate as normal during the working day. The works involved:
- Surveying and setting out of all works inc Thermoplastic Lining
- Re-alignment of arterial gullies
- Carriageway re-alignment
- Planing and disposal of the existing porous carriageway to a depth of 100mm which resulted in approximately 1,100.00 tonnes.
- The supply and lay of over 720 tonnes of 20mm Dense Binder Course
- Application of hot tanker applied bond coats
- The supply and lay of over 520 tonnes of 10mm SMA
Derek Lewis expertise was highlighted in the planning and execution of this project, with a combination of good weather and efficient workmanship resulting in the project being completed in two weeks, rather than the scheduled 3 weeks.
