Constraints:

- Castlefield is a residential area, with a local primary school/nursery, mosque, church, shops, bus route, on-street parking and private accesses.
- The traffic calming and associated works are principally located around the main route of Rutland Avenue.
- The works are compartmental in nature due to measures being positioned over a number roads in the locality to provide the most impact.
- The construction of measures and junction changes on Cross Road and Spearing Road in particular will be restricted due to both roads being one-way.
- Appropriate access to residential properties will be needed during construction.
- A considerate phasing of works will be welcomed by the client and local community groups.
- Due to the proximity of the school, restrictive hours may apply with permissible working times of 9am – 3pm and any temporary traffic lights must be manually controlled at peak times such as school drop off and religious gatherings/services.
- Consideration for size and placement of site compound/welfare facilities, storage and associated site security
- Indicative construction programme is from late April to late September 2024.

We are intending to run an open tender process via the Pro Contract portal from mid/late February 2024 for approx 5 weeks max. The future tender package will include a full set of drawings with a Bill of Quantities (BoQ) along with a PCI (Pre Construction Information) document, and NEC4 Short Form Option B (currently proposed) contract.

Following review, please can you advise if you are interested and have the necessary resource available to undertake this work by responding and expressing your interest no later than midday on Monday 19 February 2023.
