Kier Marriott and Wastecycle at Bowbridge Primary School 1

Executive summary

The new education building for Bowbridge Primary School was created with the vision to be as near carbon

neutral as possible in design, construction and use and to be delivered within a defined budget. The project was

completed in September 2008 at a cost of £3.2 million.

To support this vision, developed by Nottinghamshire County Council (the client and designer) and Bowbridge

Primary School (the end-user), the project construction contractor, Kier Marriott, worked with Wastecycle to

divert construction waste from landfill and report waste management data.

The design of the building incorporated many sustainable features including:

� the orientation and layout of the building;

� the use of recycled and renewable materials and pre-fabricated components in the construction; and

� the incorporation of wood fuelled heating, solar water heaters and rainwater harvesting in the building.

To embed the vision for the project through the construction phase, a ‘Building Charter’ was established

collaboratively between Nottinghamshire County Council, Bowbridge Primary School and Kier Marriot, that

included a requirement to reduce waste to landfill by reusing and recycling waste where possible.

Kier Marriott operates a regional and national supply chain for the procurement of all sub-contractors including

waste management contractors. The companies are required to meet certain standards in order to remain on the

supply chain and are subject to regular audits to review procedures and progress.

Kier Marriott identified that space constraints on the project site would only enable limited on site segregation of

wastes and therefore it was important to appoint a waste management contractor that could deliver high rates of

recycling of waste from mixed stream collections

Wastecycle was appointed to manage the skip waste from the project. The company offered segregated and

mixed waste collections as well as average recycling rates of around 86% for all materials managed at the

company’s materials recovery facility (MRF).

Wastecycle provided waste management data reports to Kier Marriott via its online customer area to enable Kier

Marriott to track progress and report against the project ‘Building Charter’ and corporate KPIs.

104.4 tonnes of mixed and segregated waste was handled by Wastecycle of which 88.9 tonnes was recycled or

recovered through the company’s MRF, achieving a recovery rate of 85.2%.

and therefore it was important to identify a waste management contractor that could deliver high rates of

recycling of waste from mixed streams.

� Wastecycle was appointed to manage the skip waste from the project and offered segregated waste

collections as well as recycling rates of 86% on average for mixed waste collections, by sorting the materials

at the company’s materials recovery facility (MRF).

� Wastecycle provided waste management data reports to Kier Marriott via its online customer area to enable

Kier Marriott to track progress and report against the project Building Charter.

1.2 The project

The new education building for Bowbridge Primary School in Newark-on-Trent, Nottinghamshire was created with

a vision to:

� be as near carbon neutral as possible in design, construction and use;

� be of innovative design and construction;

� provide an exemplar for Nottinghamshire County Council in its programme of new school buildings; and

� be delivered within a strict budget.


The project involved the construction of a new school building to replace the existing converted 1940’s army

barracks. The new two storey building contains ten classrooms, five group study rooms, a meeting room and

large atrium, as well as an outdoor covered playground and other outdoor learning areas.

The project was undertaken as part of Nottinghamshire County Council’s schools construction framework. The

programme of stakeholder consultation began in 2005, the construction programme commenced in September

2007 and was completed in September 2008, at a cost of £3.2 million.

1.3 Client and designer: Nottinghamshire County Council

Nottinghamshire County Council played a dual role in the project:

� the Resource Department: provided the architect, landscape architect, quantity surveyor, and electrical and

mechanical engineers; and

� the Education Department: provided advisory services and information and communication technology (ICT)

systems support.

Nottinghamshire County Council established clear objectives for the project through broad consultation with the

end-user and the wider community.

“The new building will express the value of education in the community and it will give a welcoming and

positive image of the school. It will be an exemplar design from the architectural point of view as well as

per its energy efficiency, ecology and sustainability, which is in the school ethos’”

Nottinghamshire County Council 2006

Nottinghamshire County Council promotes the principles of sustainable development and construction across the

county through the ‘Sustainable Developer Guide for Nottinghamshire’1. The Guide sets out development

principles across a range of topics including:

� planning;

� land use, layout and landscape;

� travel and transport;

� building design and specification;

� energy use;

� renewable energy;

� health and pollution;

� waste reduction;

� water use and drainage;

� biodiversity;

� community;

� historic environment; and

� maintenance and management.

Areas of consideration under waste reduction include:

� applying the waste hierarchy principles (reduce, reuse, recycle, recover, dispose);

� reducing construction waste arising through efficient design and onsite reuse of materials;

� using construction materials with recycled content; and

� providing facilities for reusing, recycling and recovering waste generated during use.

The Guide also promotes the use of locally sourced materials and resources including staffing.

1.4 End-user: Bowbridge Primary School

The building needed to provide a suitable learning environment for the school as well as a focal point for the

community. The building also supported the school’s ambition to achieve the Eco-Schools ‘Green Flag’ award (the

highest accreditation). Bowbridge Primary School expressed that the building should be a ‘learning building’ as

well as a ‘building of learning’, the intention being to utilise the way the building operates to assist the school in

teaching around a focus of education for sustainability.

The end-user played a lead role in driving the development of the project, through consultation with stakeholders

and driving the focus on sustainability.

2.0 Background

Nottinghamshire County Council procured a construction framework contract for the delivery of its schools

upgrade programme. The framework contract commenced in December 2006 and was for a period of three

years. The overall budget for projects to be delivered under the framework contract was approximate £170

million over the three year framework.

Nottinghamshire County Council procured and delivered the framework contract under the New Engineering

Contract (NEC). This form of contract is commonly used in publicly funded construction projects and includes

options for using key performance indicators and incentive schedules and has been designed to promote

partnership working and drive out inefficiency.

The framework procurement process included a number of stages involving:

� pre-qualification questionnaire;

� full proposal;

� site visit; and

� interview.

Nottinghamshire County Council appointed three construction contractors to the framework, including Kier

Marriott. The Council identified a range of KPIs and, as an incentive, each construction contractor’s performance

against the KPIs during the first year of the framework would influence their likely share of the work let under the

framework during years two and three.

The construction of the Bowbridge Primary School project was let to Kier Marriott through the County’s

framework contract. Under the framework, the construction contractor gets involved in the development of a

project at an early stage.


2.1 The Design

Nottinghamshire County Council and Bowbridge Primary School drove the integration of sustainability into the

design process for the project. A wide range of design objectives and features with sustainability and resource

and energy efficiency benefits were incorporated into the design that included:

� energy efficient features including a large south facing atrium to act as a passive collector in the winter and a

ventilation stack in the summer, building layout and orientation designed to promote light and solar gain in

appropriate parts of the building and passive ventilation design;

� flexible layout to accommodate a range of teaching and other activities;

� constructed mainly from renewable and / or recycled materials;

� locally sourced materials;

� high specification insulation;

� a wood burning boiler as the main source of heating;

� solar water heaters; and

� rainwater harvesting.

The building design and construction methods also significantly reduced waste generated on site. The building

comprised a timber frame and insulated timber panel walls and roof deck that were pre-fabricated off site and

simply assembled on site reducing surplus materials and waste. In addition, the temporary access road for the

site was constructed from recycled aggregates and incorporated a ground stabilising geogrid which maintained

the quality of the recycled aggregates and enabled its reuse in the construction of the new netball courts. Bricks

were also reclaimed from the site and reused in areas of the new build.

The design endorsed the principles defined in the ‘Sustainable Developer Guide for Nottinghamshire’1 and was

developed in consultation with school staff, pupils, parents and the local community from project inception

through to completion.

The project was also to serve as an exemplar design for Nottinghamshire County Council as it continues to roll

out new school buildings under the Private Finance Initiative (PFI) and Building Schools for the Future (BSF)

programme.

2.2 Building Charter

To ensure that the strong environmental and sustainability ethos that had been embedded throughout the design

phase of the project was positively embraced by the construction team, a ‘Building Charter’ was produced

collaboratively between Bowbridge Primary School, Nottinghamshire County Council and Kier Marriott.

The ‘Building Charter’ established that ‘the construction of the building should be consistent with the principles

already set in its design and in the Sustainable Developer Guide for Nottinghamshire………… the building should

be constructed in such a way as to minimise environmental damage’.

The Building Charter established guidance for:

� procurement of materials, including using sustainable or renewable sources of materials, that avoid excessive

packaging and have minimal impact during extraction / manufacture;

� travel and transport, including procuring local materials and using local contractors;

� energy use, including using bio-fuels and reducing the use of fuel;

� health and pollution, including using natural materials;

� waste reduction, including recycling / reusing as much waste as possible from site to avoid landfill or

incineration;

� water use and drainage, efficient use of water;

� maintenance and management, including ethical financing and carbon footprinting; and

� community, including regular consultation with pupils and the community and use of local workforce.

The Building Charter was to be adhered to wherever possible (within budget constraints) by Kier Marriott as well

as all sub-contactors.


The early involvement of the construction contractor in the project enabled a collaborative approach to the

development of the ‘Building Charter’.

2.3 Key drivers

The key drivers for the project include:

Client and designer – Nottinghamshire County Council

� Delivery of a new school building for Bowbridge Primary School, on time and to budget, that meets the needs

of pupils, staff and the community.

� Providing an exemplar in architectural design and sustainability for use in future projects.

� Delivering the project in line with the principles of the ‘Sustainable Developer Guide for Nottinghamshire’.

End-user - Bowbridge Primary School

� Providing a new school building that delivers a high quality learning environment for pupils and staff.

� Providing a flexible building that meets the needs of the school and local community.

� Supporting the school’s objective to achieve the Eco-Schools ‘Green Flag’ award.

Construction contractor – Kier Marriott

� Delivering client and end-user objectives.

� Delivering the framework KPIs to ensure the award of future projects.

� Delivering against corporate KPIs.

Waste management contractor – Wastecycle

� Achieving target recycling rates.

� Delivering company objectives and targets and achieving continuous improvement.

� Recycling as much waste as possible to reduce costs for the company and customers.

� Delivering customer requirements.

� Building long-term business relationships to secure future work.

3.0 Procurement process

Kier Marriott operates a regional and national supply chain that includes an approved suppliers list for all sub-contractors, including waste management contractors. Sub-contractors are expected to maintain defined standards to remain as an approved supplier and undertake work for the company.

Kier Marriott procures waste management services via its regional supply chain of approved suppliers. The Kier

Group also operates a national supply chain for specific products and services that are only available through a

limited number of suppliers across the country.

Kier Marriott introduced a programme of auditing of the waste management contractors that are on the regional

and national supply chain. The company applies a set of auditing criteria that define the minimum standards

expected from a waste management contractor on the supply chain (see Section 8.0 for details).

Kier Marriott uses this approach to ensure that the waste management contractors on the supply chain support

the company’s objective to reduce waste to landfill by operating under complementary policies that drive good

practice in their particular area of expertise.

3.1 The Process

For a particular project, Kier’s Buyers discuss the specific waste management requirements with the construction

site manager and local environment team. These requirements include:


� waste quantities;

� waste types;

� potential for on-site segregation;

� responsibilities of each party; and

� any site constraints.

On the Bowbridge Primary School project, space for skips and waste collection containers on the site was

constrained and therefore Kier Marriott concluded that the opportunities for on site segregation were limited. In

order to meet the requirements of the ‘Building Charter’ and to deliver high rates of waste diversion from landfill,

Kier Marriott concluded that it was important to identify a waste management contractor that could achieve these

requirements through on site segregation of major waste streams together with off site segregation of mixed

waste collections. In addition, a local waste management contractor (located within 50 miles of the site) was

needed to meet the ‘Travel and Transport’ and ‘Community’ elements of the Building Charter.

For the Bowbridge Primary School project the waste management services were divided into three parts as

follows:

� Wastecycle was used for skip waste;

� specialist contractors were used for muck-away and asbestos; and

� the school’s existing waste collection service was used for collecting paper and card for recycling.

Wastecycle was awarded the skip waste collection because:

� the company was able to offer both segregated and mixed waste containers and collections;

� recycling rates at the company’s MRF are typically 86%;

� the company was located within 50 miles of the project site; and

� the company was able to supply waste management data to support Kier Marriott’s reporting requirements.

3.2 Procurement process – Summary

� Kier Marriott operates a regional and national supply chain which includes waste management service

provision.

� Kier Marriott sets minimum requirements for waste management contractors on the supply chain and

undertakes regular audits to confirm performance.

� Kier Marriott’s site manager and environment team work with Kier Buyers to identify waste management

requirements and constraints on a project and place an order with an appropriate waste management

contractor.

4.0 Contract arrangements

The contractual arrangements between Kier Marriott and Wastecycle are based around a supply chain agreement and project specific requirements. 4.1 Contract conditions and requirements

The contract between Kier Marriott and Wastecycle involves a supply chain agreement with project specific

service arrangements. The two companies worked together to identify the most significant potential waste

arisings and propose a suitable waste segregation strategy.

At the start of a project Wastecycle prepares a price proposal for waste management services based on:

� size of a waste container or skip;

� transport distance;

� expected waste composition;

� whether the waste streams will be source segregated or mixed; and


� recycling rates expected to be achieved for the particular waste streams.

Waste that is segregated by the customer is generally charged at a lower rate than mixed waste, which reflects

the lower operational cost to Wastecycle. The price per skip and waste type is usually fixed for the duration of a

project.

As part of the contract, Wastecycle also provides waste data reporting services via the company’s online customer

area.

4.2 Contract management

Kier Marriott and Wastecycle worked closely to understand the requirements of the project and to build an

effective working relationship.

To ensure that the expected standards are maintained, Kier Marriott undertakes regular auditing of the waste

management contractors that are on the regional and national supply chain. The company reviews a set of

auditing criteria that define the minimum standards expected from a waste management contractor on the supply

chain (see Section 8.0 for details). As part of the management of the contract on the project, Kier Marriott

audited Wastecycle.

5.0 Service delivery

Wastecycle provided a range of waste management services focussed on the recycling of waste through its materials recovery facility in Nottingham.

Wastecycle provided skips and containers for mixed and segregated waste collections from Bowbridge Primary

School. Due to space constraints on the site, only limited site segregation was feasible and was therefore

targeted at the most significant streams and those which had specific handling requirements, as follows:

� timber was source segregated and stored within an 8 cubic yard skip. This stream was expected to arise from

the construction of the timber frame and fit out phases;

� plasterboard was source segregated and stored within a separate container within the mixed waste skip so

that it could be easily lifted out at the MRF to ensure separation of the stream; and

� general / mixed waste was stored within an 8 cubic yard skip.

Figure 1 Mixed and segregated waste collection at Bowbridge Primary School


Wastecycle provided the skips and containers and collection of the wastes. All waste was taken to the company’s

materials recovery facility in Colwick, Nottingham where:

� timber is shredded and supplied to a range of specialist end users;

� plasterboard is collected and sent to a reprocessor; and

� mixed waste is fed through the MRF where it is sorted into a range of material streams and either baled or

bulked for supply to reprocessing plants (e.g. paper, plastics) or further processed for direct onward sale (e.g.

aggregates, soils).

Figure 2 Processing wood waste at Wastecycle’s MRF

6.0 Data collection, collation and reporting

Wastecycle prepared waste data reports for Kier Marriott that were accessed via an online customer area.

Wastecycle offers waste data reporting as part of its service to customers. Data reports are accessed via a

dedicated online customer area with a customer specific login.

The online area provides customers with a range of reports and database search options to enable data to be

extracted in a form that is suitable for various needs. Kier Marriott’s project manager used the online area to

track waste generation, segregation, recycling and disposal for the project.

The data reports show information by:

� skip / container movement;

� construction project / site; or

� for all projects for a particular customer.

Database search options enable the data to be reviewed for a user-defined timescale or for the life of the project.


For each skip / container movement, the data report includes:

� the skip / container volume;

� description of the contents of the skip;

� weight of the waste; and

� recycling rate – reported as the waste management facility average for that day.

The waste within a skip is categorised into one of 12 different waste streams as follows:

� card;

� confidential waste;

� general mixed;

� glass;

� inert;

� metal;

� mixed recyclables;

� paper;

� plasterboard;

� plastic;

� secure burial; or

� wood.

For each waste stream the report shows the:

� total tonnage of waste collected;

� tonnage segregated by the producer and recycled by Wastecycle;

� tonnage segregated and recycled by Wastecycle;

� tonnage sent to landfill; and

� total recycled.

Wastecycle records data on all waste that it collects and manages. The data is collated from the Waste Transfer

Note and site weighbridge records. All waste collection vehicles entering and leaving Wastecycle’s MRF are

weighed on the calibrated weighbridge. The weight of the full and empty vehicle and waste container are

compared in order to determine the weight of the waste that has been deposited at or removed from the MRF.

The Waste Transfer Note and the weighbridge records are also used for invoicing and payment purposes and in

Wastecycle’s reporting to the Environment Agency.

The above data can be reported by month or year to date or cumulative for the project. The tonnage segregated

and recycled by Wastecycle is calculated from the MRF average recycling rate for that particular day. Wastecycle

also offers recycling rate data for individual skips / consignments, although a surcharge is usually charged for this

service.

The online customer area holds waste data for each site / project being undertaken by Kier Marriott where

Wastecycle are providing the waste management services. This function enables Kier Marriott to compare waste

management performance between projects and identify sites that are performing well or require improvements.

This enables Kier Marriott to target specific improvements that will impact on performance across the business.

Examples of waste data reports prepared by Wastecycle are shown in Figure 3.


Figure 3 Examples of Wastecycle data reports


6.1 Other data reporting

Kier Marriott uses the waste data to:

� report to Nottinghamshire County Council and Bowbridge Primary School on a monthly basis against the

requirements of the ‘Building Charter’;

� compare the recycling and waste management performance across Kier Marriott projects;

� identify examples of good practice and opportunities and actions required for future improvements; and

� report against business and Kier Group KPIs.

Wastecycle uses the waste data to:

� monitor recycling rates and operating efficiencies for the business;

� make decisions regarding future investment in new plant and equipment; and

� meet regulatory reporting requirements for completing Waste Returns as required by the Environment

Agency.

7.0 Use of the Site Waste Management Plan

Kier Marriott began using Site Waste Management Plans (SWMPs) for construction projects in 2007 before they

became a legal requirement in England under the SWMP Regulations 2008. The SWMP forms part of the Health

and Safety Plan on a project and is a live document that is continually updated throughout the project.

The SWMP for Bowbridge Primary School was prepared at the pre-contract stage and implemented and updated

as the project progressed.

8.0 Auditing

Kier Marriott undertakes regular audits of waste management contractors on its supply chain. Wastecycle’s management procedures are audited as part of the company’s accreditations.

8.1 Auditing procedures

Kier Marriott has introduced a regular programme of auditing of all waste management contractors on its regional

supply chain. The purpose of the audits is to ensure that standards and procedures are being maintained and

implemented, and to assist in ensuring the quality of waste management service provision. The audits are usually

undertaken by the local environment team and include a half-day site visit and an interview. Kier Marriott has

developed a general list of criteria against which the waste management contractor is audited, which includes

legal requirements as well as service options and good practice approaches across 14 areas of activity, as follows:

� appearance of facility;

� safety;

� people;

� service collection;

� locality to project;

� quality of product;

� documentation/systems;

� number of waste streams;

� recycling rates;

� capacity;

� local benefits;

� culture and landfill policy;

� vehicles and plant; and

� certification.


The audit regime also reviews the waste management contractor’s proposed future improvements and planned

investment in plant and equipment to ensure the company is committed to offering the highest quality of service.

The waste management contractors on the supply chain are generally audited once or twice a year, with further

audits undertaken for specific construction projects. Any waste management contractor that is new to the Kier

Marriott supply chain is required to meet the standards and be accommodating of the auditing process.

As part of the Bowbridge Primary School project Kier Marriott’s environment team audited Wastecycle to ensure

expected standards of service were being delivered.

Wastecycle operates under a quality management system accredited to ISO 9001:2000 and an environmental

management system accredited to ISO 14001:2004. As part of the accreditation, Wastecycle is required to

undertake regular audits both internally and by an approved independent third party, in order to confirm that

procedures set out by the company are being implemented effectively. The accreditation also requires Wastecycle

to demonstrate continuous improvements in its management systems and processes.

8.2 Waste data auditing

Wastecycle monitors the recycling rate achieved at its MRF by weighing incoming waste, outgoing recyclate and

outgoing waste to landfill. Wastecycle is required to report this data on a quarterly basis to the Environment

Agency on its Waste Returns form. This reporting is required as a condition of the site licence / permit but also

enables process efficiencies to be monitored. The weighbridge is used to weigh all waste entering and leaving the

site and is regularly calibrated in accordance with requirements.

9.0 Outcomes

Kier Marriott and Wastecycle worked together to divert waste from landfill, reduce costs and achieve client objectives.

� 104.4 tonnes of mixed and segregated waste was handled by Wastecycle of which 88.9 tonnes was recycled

or recovered, achieving a recovery rate of 85.2%.

� Kier Marriott worked with Wastecycle to effectively deliver outcomes that supported the objectives of the

project ‘Building Charter’, the construction framework KPIs and corporate KPIs.

� Nottinghamshire County Council and Bowbridge Primary School established a clear vision for the project that

was embedded throughout the design and construction phases and through the supply chain to Kier Marriott

and Wastecycle. The collaborative approach achieved waste reduction, the use of recycled content and the

reuse, recycling and recovery of waste.

9.1 Key learning points

Kier Marriott identified key learning points as:

� cost effective waste reduction and diversion of waste from landfill can be achieved by establishing a clear

vision and objectives early in a project and working collaboratively throughout the supply chain to embed and

deliver the objectives;

� the quality of waste management service provision can be enhanced by defining requirements expected from

waste management contractors, establishing a supply chain that meets the requirements, and auditing and

reviewing service provision on an ongoing basis;

� understanding the capabilities and range of services offered by waste management contractors and

developing a partnership approach to working can ensure expected service levels are delivered or exceeded

and continue to improve;

� waste management contractors can provide support in the planning, delivery and reporting of construction

waste management; and

� clients often consider sustainability issues to be of significant importance in projects and expect companies on

the supply chain to demonstrate how they will deliver measures that are both sustainable and cost effective.


Wastecycle identified key learning points as:

� by providing waste management services that support construction contractors objectives to provide cost

effective reductions in waste to landfill, effective long-term relationships can be developed; and

� good communications between the contract manager and site manager help to ensure the delivery of

expected standards of service in a timely and consistent manner.

10.0 Next steps

Kier Marriott and Wastecycle continue to identify and implement improvements in waste management performance and service provision.

� Kier Marriott is using the knowledge and experience gained at Bowbridge Primary School to demonstrate to

new clients the actions that can be taken to increase the sustainability of projects and reduce waste. This has

contributed to the company being appointed to additional framework and project contracts.

� Wastecycle is developing an improved data reporting tool on its online customer area to support

developments in SWMPs and requirements from customers.

� Kier Group is establishing waste management service contracts that include requirements for reporting waste

data in a way that supports the company’s approach to delivering SWMPs.

� Kier Marriott is undertaking a review of the waste management contractors on the regional supply chain to

ensure existing and new companies meet defined criteria.

� Kier Marriott has developed a Waster Transfer Note proforma that is used by site staff to record the

approximate composition of the waste within mixed waste skips. This process enables the capture of data on

mixed waste streams to inform decisions on waste segregation and management. Kier Marriott is also

requiring waste management contractors to undertake a similar exercise. This enables the data to be cross-

checked and gives greater confidence in the outcomes.

� the Bowbridge Primary School project has successfully achieved a number of awards including the RICS East

Midlands Award 2009 for Sustainability.
