1 Introduction

As part of the ongoing redevelopment of the existing Jersey General Hospital an

area of the current estate, as well as some of the surrounding buildings, will be

demolished to make way for a new-build hospital, the project is known as Jersey

Future Hospital (JFH). This building consists of a single storey partial basement,

with up to 8 storeys above ground. In addition to this work, it is proposed to add

two half decks of car parking (1,290m2) as part of the extension. This process will

include the demolishing and rebuilding of an existing car park (900m2).

The current general hospital site is located on Gloucester Street to the west of St

Helier town centre, and is bounded by Kensington Place to the north, by Newgate

Street to the west and by The Parade to the east. The hospital estate consists of

nine main structures, refer to Figure 1.

2 Assumptions

This section sets out the assumptions for the calculations and sizing of logistics

areas.

2.1 Trip Rates Construction Traffic

Trip rates, expressed as number of vehicles/100m2, applied during this study are

as follows:

Demolition: 8 vehicles/100m2/day;

Sub Structure: 5 vehicles/100m2/day;

Concrete pours: 15 vehicles/100m2/day;

Super Structure: 10 vehicles/100m2/day; and

Fit-out: 7 vehicles/100m2/day.

2.2 Working Hours

Working hours will be in accordance with the requirements of the Considerate

Constructors Scheme, currently no anticipated requirement for activities to be

undertaken outside these times:

• 0800 – 1800 Monday to Friday.

3 Construction Traffic

This section sets out to provide guidance and information on the type of

construction movements and types of vehicles used to process waste and goods

into and away from the construction site. The types of vehicle movements

associated with construction traffic are as follows:

Workforce movements to/from the site;

Deliveries made to the site;

Removal of material from the site; and

Trips made by associated trades.

Each of these movements will be associated with different types of vehicle or

plant. These vehicles are considered in the next section.

3.1 Construction Vehicles and Plant

Consideration should be given to the type of vehicle and plant that is likely to be

used during the demolition and construction works. These may be identified and

grouped according to their size:

Car/pick up/3.5 ton van;

7.5 ton box van/panel van;

Low loader and articulated Heavy Goods Vehicle (HGV);

Ready mix concrete truck;

Mobile crane;

Water bowsers;

Road cleaning vehicles;

Skip lorry; and

32 ton tipper truck.

Developments are often completed in phases, with earlier stages often requiring

greater use of HGVs for site clearance and bulk delivery of construction materials.

3.2 Stakeholder Impact Assessment

An assessment should be made to assess and address the impact of construction

activity upon all stakeholders, including pedestrians, cyclists, public transport and

vehicular users, and include consideration of the access and servicing

requirements of affected residential and commercial premises. The use of

temporary traffic and site management measures can have a wide range of

repercussions for different users, which are illustrated below:

Pedestrian footways narrowed, temporary closures, diversions and temporary

footways of varying quality;

Cycles routes closed, narrowed, diverted, reallocation of parking;

Bus services diverted, suspended and relocation of bus stops and stands;

Taxis rank relocation;





Page 7

In terms of traffic movements:

Lane closures and/or shuttle working with signal control;

Introduction of one-way streets, reversed flows and removal or introduction of

banned turns;

Road closures with signed diversions;

Changes to traffic signal timings;

Temporary speed limits;

Parking suspension and/or reallocation; and

Disruption arising from the construction site is generally more localised in its

effects, typically noise, vibration, dust and dirt, and a loss of amenity due to

the presence of heavy construction traffic.

The potential source of adverse impacts associated with demolition and

construction works are presented in table 7.





Page 8

Potential Impacts During Demolition and Construction

Issue Potential Impacts

Noise Increased road noise levels from vehicles. Increased noise levels

from plant during demolition, piling and general construction works

(e.g. from the use of air compressors and diamond cutters).

Vibration Increased vibration levels from vehicles. Increased vibration levels

from plant during demolition, piling and general construction works

(e.g. from piling rigs).

Dust / Air

Quality

Windblown dust from ground surfaces, stockpiles, vehicles, work

faces and cutting and grinding of materials. Exhaust emissions from

lorries and plant delivering and removing materials including dust

and particulates.

Waste Waste generation and its disposal.

Water Increased sediment loadings to storm-water system. Potentially

contaminated storm-water runoff.

Traffic Traffic congestion caused by site traffic and traffic associated with

road diversions and deliveries. Increased vehicle movements mainly

consisting of Heavy Goods Vehicles (HGVs). Transfer of mud and

material from vehicles onto the public highway. Disruption from

abnormal or hazardous loads. Exhaust emissions.

Storage of fuels and

construction

materials

Accidental spills, discharges to drains/storm-water systems,

contamination to ground.

Pedestrian access

Restrictions on pedestrian access to walkways, footpaths and roads.

Hazardous and contaminated

materials

Exposure of the workforce to deleterious / hazardous materials and

contaminated land, mobilisation of any source contaminants and

creation of pathway from source to groundwater receptor.

Ecology Water / mud runoff into the drains.

Energy Usage

Indirect impacts associated with energy consumption such as CO2

emissions, depletion of natural resources, air pollution etc.

Views

Views impacted and/ or impeded from construction equipment,

particularly cranes.

Table 7 Potential impacts from demolition and construction activities

The role of the principal contractor will be to implement a Demolition and

Construction Method Statement (DCMS). The DCMS will be a contractual

document outlining the different procedures to be undertaken to complete the

various works. Individual subcontractors will incorporate requirements for

environmental control, based on good working practice, such as careful

programming, resource conservation, adhering to health and safety regulations

and quality procedures. In this way those involved with the demolition and

construction phase, including subcontractors and site management, will be

committed to adopt the agreed best practice and environmentally sound methods.

The DCMS will be prepared in consultation with and approved by the local

authority. The subcontractors will be required to demonstrate how they will meet





Page 9

the target of the DCMS and how the potential impacts will be offset, reduced or

minimised. The DCMS will include the following main items:

The Demolition and Construction Programme;

A broad plan of the demolition and construction works, highlighting the

various stages and their context within the project;

Detailed site layout arrangements (including requirements for temporary

works), plans for storage, accommodation, vehicular movements, delivery and

access;

Prohibited or restricted operations (locations, hours, etc.);

Details of operations that are likely to result in disturbance, with an indication

of the expected duration of each phase with key dates, including a procedure

for prior notification to the local authority and relevant statutory and non-

statutory (including neighbours) parties so that local arrangements can be

agreed; and

Site working hours.

A procedure to ensure communication is maintained via the contractor with the

local authority and local community to provide information on any operations

likely to cause disturbance (through, for example, meetings and newsletters).

3.3 Managing construction traffic

This should be prepared in consultation with highway and traffic authorities and

provide the strategy for managing and mitigating the identified impacts. It should

address:

site boundaries and main access/egress locations;

traffic management strategy;

temporary and permanent closures and diversions of highways and public

rights of way;

HGV routing (both locally and if necessary strategically), including signing,

holding areas/consolidation centres, abnormal loads, prohibited routes and means

of monitoring HGV use.

Requirements for a Construction Traffic Management Plan are set out in Table 8.

Construction Traffic Management Plan

Measure Considerations

Supply Chain

Optimisation

The logistics industry has developed a range of techniques to

maximise efficiencies within the supply chain. Perhaps most well-

known is the concept of ‘Just In Time’ delivery, although general

supply chain optimisation addresses ranging, procurement, storage,

distribution and back loading activities to maximise load

optimisation.

Delivery logistics Delivery booking (deliveries by pre-arranged time slots), which can

be used to enable delivery of materials either as part of a Just in

Time operation so that materials only arrive on site when needed

scheduled), or as part of a ‘smoothing’ operation to enable the peaks

and troughs in demand to be evened out over a period of time, or to

avoid certain time periods such as morning and evening peaks, or

school start and finish times.

Load Consolidation Off-site consolidation of materials (where suitable off-site can be

identified and procured), providing ‘Just In Time’ deliveries and

reducing access congestion and on-site material storage. This is

particularly useful if the development site is constrained for suitable

storage space, or faces access constraints.

Route Mapping Routing and scheduling arrivals may make it possible to reduce trips

to a site, by providing a more organised, logistical style method of

operation. Routes should be surveyed and swept path analysis

undertaken.

Operating Hours Restricted site operating hours, especially on sites adjacent to

sensitive sites such as schools, hospitals and residential areas.

Construction Travel Plan Employees to use walking, cycling and/or using public transport can

reduce the number of trips to a site. A minibus may be used to

transport workers in bulk to the site. This has the advantage of

restricting traffic generation to the daily arrival and departure of

staff employed on site, as well as removing the need for car parking

facilities on site.

Programme Compression The severity of any adverse impacts could be balanced by

compressing the programme of phases, thereby causing greater

disruption over a shorter time period, or overlapping certain

activities.

Noise Restrict operating hours, compress activities to minimise disruption.

Vibration Restrict operating hours, compress activities to minimise disruption.

Dirt Wheel washing and load covering.

Construction Methods Consider alternative construction methods, such as prefabrication,

onsite concrete mixing etc. to minimise external site trips.

4 Construction Traffic Calculations

This section sets out the estimated number of construction vehicles for JFH for

each of the four phases of construction. The calculations are based on survey data

obtained from a range of sites within central London. These sites varied from

small (12,999m2), medium (42,000m2) and large (68,000m2) developments in

terms of area. This study includes the number of vehicle movements associated

with the partial demolition and construction of the car park as follows:

The partial demolition of the existing car park applying an area of 900m2; and

The construction of the new half decks applying an area of 2,580m2.

4.1 Demolition Phase

4.3.1 Concrete Pours - Foundations

This section sets out the total for the peak number of deliveries associated with the

construction phase of the project including the ready mix concrete trucks for

completing the foundations. This will be the busiest period of the process in terms

of daily deliveries. It is proposed to deliver concrete during following times:

12 No. deliveries between 08:30 – 09:30 hours, a total of 12 deliveries; and

10 No. deliveries per hour between 09:30 – 15:30 hours, a total of 60

deliveries.

A further 12 daily deliveries are proposed for all other site activities. Therefore, it

is estimated that 84 deliveries per day (with a peak hour of 12 deliveries) would

visit the construction site. Table 11 presents the estimated vehicle trips for this

time.
