4 1 Introduction 1.1 PREAMBLE WSP has been commissioned by Taylor Wimpey and Barratt Strategic to provide transportation advice in support of a proposed planning application for the development at Radstone Fields, Brackley in Northamptonshire. Development at the site includes up to 1,000 residential units and ancillary uses This note provides an assessment of construction traffic to and from the site demonstrating that construction materials can be delivered, and waste removed, in a safe, efficient and environmentally-friendly way. The Construction Traffic Management Plan will minimise negative impacts on nearby residents, the local highway network and the environment Full details of the transportation implications of the fully developed site are provided in the overarching Transport Assessment which has been submitted with the main application. 1.2 STRUCTURE This Construction Traffic Management Plan is set out in the following sections: Section 2 Development Phasing: Details the proposed programme of development; Section 3 Traffic Generation: Sets out the anticipated number of construction vehicle and construction worker trips; Section 4 Access, Routing and Impact Assessment: Assesses the effect of construction traffic accessing and routing to and from the site; and Section 5 Construction and Logistics Plan: Sets out measures that will be employed to minimise the impact of construction traffic Radstone Fields, Brackley 1

5 2 Development Phasing 2.1 PHASING Construction and occupation of the site s development is likely to take approximately seven years from a start in 2012 to completion by The construction of the Radstone Fields development will be delivered by both Taylor Wimpey and Barratt Strategic throughout the seven years and is anticipated to be delivered at the same rate, as such the anticipated build programme is set out in Table 2.1 below.

6 3 Traffic Generation 3.1 TRAFFIC GENERATION During the construction of the proposed development it will be necessary for various plant, equipment and materials to be transported to the site. Construction is programmed to commence during 2012 and would continue until The number of HGV movements associated with the construction of the site is based both on the composition of the proposed development and on experience of similar sites elsewhere. Considering an average build out rate of 170 dwellings per year and there being 275 working days per year, the number of HGV and construction worker trips has been determined At the peak build period, it is anticipated that there will be 26 two way HGV vehicle movements per day and 88 construction worker two way trips per day. 3.2 ON-SITE CAR PARKING Sufficient on-site parking for construction workers will be provided to meet demand. Priority for parking will be given to those personnel who need to carry heavy equipment or materials. A parking management strategy will be implemented to monitor the parking provision, to encourage car sharing and where possible travel by sustainable means and to ensure the no off-site parking occurs. Where possible the impact of employee traffic would be minimised through employment of local labour and using local businesses for the supply of materials Radstone Fields, Brackley 3

7 4 Access, Routing and Impact Assessment 4.1 INTRODUCTION When the proposed development is completed there will be three vehicular access points. These are as follows: Halse Road; Radstone Road (Southern); and Radstone Road (Northern) However, certain constraints and sensitivities limit the movement of heavy goods vehicles and plant that would be associated with the development process. Access arrangements for construction traffic therefore differ from those proposed for residents. Details in regards to construction access arrangements are included below. 4.2 CONSTRUCTION ACCESS ARRANGEMENTS Due to the fact that the site will be developed separately from the eastern and western sides of the site, it is imperative that construction traffic is able to access both developable areas. However, the access arrangements have to reflect the need to minimise the impact on the local highway and avoid particularly sensitive locations The access strategy for the site has been determined in response to local residents and Councillors concerns about the impact of HGV and construction traffic, particularly on the southern section of Halse Road, towards the town centre, where the narrow urban form and on-street parking would make it difficult for large numbers of HGVs to route through. As such no heavy goods vehicles or plant associated with the construction process will access the site via the southern section of Halse Road, where the network is most constrained. Instead all HGV traffic, entering via the western access, will do so via Banbury Road, Pavillons Way and then onto Halse Road It is anticipated that construction traffic will only access the site via Pavillons Way for a limited period of between three and six months at the beginning of the construction process. This will enable time for the Halse Road site access to be constructed alongside a possible Haul Route through the site after which alternative means of access will be determined Consideration will be given to the construction of a Haul Route through the site. The provision of such would allow construction traffic, destined for the western development parcels, to access the site via Radstone Road further reducing any impact on Halse Road. 4.3 CONSTRUCTION ROUTING ASSIGNMENT As shown on Figure 1, all construction traffic external to Brackley will route via the A43/Northampton Road junction or A422/Banbury Road junction, this will ensure that the impact on local roads is minimised. It has been identified that access to these two points will occur from four proposed routes which in turn feed into the wider strategic highway network, these routes are as follows: From the North and East: M1 Junction 15a, A43, Northampton Road, Radstone Road; From the East (Local): A422, A43, Northampton Road and Radstone Road; Radstone Fields, Brackley 4

8 From the South: M40 Junction 10, A43, Northampton Road, Radstone Road & M40 Junction 10, A43, Pavillons Way, Halse Road; and From the West: M40 Junction 11, A422, Pavillons Way, Halse Road In order to determine the likely distribution of HGV movements between the four access routes a desktop study was undertaken to identify likely origins/attractors for construction traffic. Further to this Annual Average Daily Flow (AADF) information for HGVs was extracted, for each of the four access routes, from the DfT website to determine existing HGV use on these routes and the likely pattern of HGV movements associated with the development. Table 4.1 below shows the HGV AADF flows for each of these links, the percentage of HGV traffic in relation to the other routes and how this then relates to the distribution for construction traffic for Radstone Fields. Table 4.1 Construction Traffic Distribution Road DfT AADF Flows (HGVs) % Distribution Radstone Fields Anticipated Distribution A43 North % 40% A422 East 183 2% 5% A43 South % 20% via Western Access 20% via Eastern Access A422 West % 15% TOTAL % 100% Source: Dft ( As the table above shows the majority of HGV movements occur along the A43; given the nature of the road, linkages to nearby major settlements and the access opportunities it provides to the north to the M1 and to the south to the M40. The majority of construction traffic associated with the Radstone Fields development would thus be expected to use one of these two routes although the influence of local origins has been taken account of within the distribution which may increase the number of HGVs on other links. 4.4 TRAFFIC IMPACT ASSESSMENT Assessments of traffic are based on a mid-build scenario, when construction traffic is anticipated to be at its peak, this is equivalent to 26 two way HGV movements in a 24hr period. Table 4.2 below sets out the number of HGV construction traffic trips expected to route via each link during a 24 hour period and the percentage increase in relation to baseline HGV flows. In the majority, HGV movements would be scheduled outside of peak hours to avoid conflict with other road users and minimise impact on junction capacity Radstone Fields, Brackley 5

Both of the roads are of a high standard and subsequently it would be expected that they would be able to accommodate these increased movements, which would be in the region of 1-2 movements per hour on average, outside of the peak hours, and subsequently have a negligible impact on the performance of the road network The movements of HGVs have been tracked along each of the access routes, from the A43 and A422, to the development site, these tracks are shown on WSP Drawing 2617/SK/017B The quantum of the increase in movements on Northampton Road, Radstone Road, Pavillons Way and Halse Road is not expected to be large enough to have a significant environmental impact on adjacent properties in regards to noise and air quality Radstone Fields, Brackley 6

10 5 Construction and Logistics Plan 5.1 INTRODUCTION In order to minimise the impact of construction vehicles, various measures will be implemented. This includes routing traffic as set along the specified Construction Traffic Routes (CTRs) which have the least impact. 5.2 STRATEGY In order to minimise the amount of construction vehicles using the public highway, the following factors will be considered: Wherever possible, any excavated spoil will be used on site; Prefabrication of construction components off-site will reduce the volumes of material deliveries of smaller components; Where possible, precast units will be used to reduce the requirement for concrete, reinforcement, pumps, formwork, scaffolding, deliveries etc To further minimise the impact of the development on the local highway, the following will be undertaken: All construction traffic entering and leaving the site will be controlled. Vehicles making deliveries to the site (if applicable), will travel via the designated CTR, which avoids sensitive locations; Construction traffic would be controlled as far as possible to times outside the peak traffic hours; Exceptional loads would be restricted to outside of peak hours; Construction activities will be co-ordinated and procedures agreed with contractors for special or unusual activities such as deliveries of large plant and road closures, disseminating information to existing residents and ensuring minimum disruption; Any temporary road closures to be undertaken outside of peak hours / sensitive periods where possible; and The construction process will be environmentally aware, with focus upon housekeeping, good quality hoardings and landscaping and wheel washing facilities The constructors will be required to follow the considerate constructor s scheme It should also be noted that facilities such as temporary offices and works compounds, storage areas for construction materials and assembly areas for components of construction will be located sensitively relative to existing residential areas. 5.3 WORKING HOURS The working hours of the site will be subject to agreement with the Local Authority. 5.4 MONITORING A programme of monitoring and review will be implemented to generate information by which the success of this section of the Construction Traffic Management Plan can be evaluated. Monitoring and review of construction activity to the site will be the responsibility of the principal contractor Radstone Fields, Brackley 7

11 5.4.2 This process will provide the opportunity for construction operations and procedures on the site to be reviewed and new management measures to be implemented (if necessary). Monitoring will be documented and available to the Local Authority upon request Radstone Fields, Brackley 8
