The project
The reclamation of Fryston and Wheldale Collieries
sites, as part of the Coalfields Regeneration scheme,
was delivered by Yorkshire Forward, supported by landowners
Wakefield MDC utilising funding provided by the Homes
and Communities Agency through the National Coalfields
Programme. The scheme was an Early Contractor Involvement
(ECI) contract with the ECI phase valued at £1.5m
and the main works valued at £8.5m. Both the ECI
and main works were won by Birse Civils. Construction
commenced on site in July 2008.
ECI works involved general site clearance, formation
of a 2-km-long access track through the site, excavation
and crushing of existing concrete stockpiles for use
as 6F2 on site and establishment of a perimeter footpath
for pedestrian use throughout the construction phase.
The site had been used as a recreation facility by the
local community and it was important to maintain this
provision.
The main works included:
- excavation and burial of approximately
1,500 cubic metres of Japanese Knotweed within a specialist
containment cell
- excavation and engineered
fill of 100,000 cubic metres of material for a proposed
10-hectare housing platform
- remodelling of 150,000 cubic
metres of material over the remaining 50 hectares
of site
- formation of 8km of bridleways
and footpaths
- incorporation of 50,000 cubic
metres of amelioration material to provide a suitable
growing medium
- planting of 30,000 saplings,
grass seeding
- creation of a leisure area
adjacent to an existing marina.
All these works were undertaken in close proximity
to the existing village of New Fryston, and close cooperation
with the local community was required at all times.
Landscaping
Landscaping works on site included the retention and
protection of existing reedbeds, wetland habitats and
areas of established woodland throughout site. A total
of 50 hectares of new woodland and grassland were created
as part of the scheme.
Ecology
Specific measures to enhance ecology and biodiversity
included:
- Creation of new habitats
- Log piles for amphibians and
invertebrates
- Installation of swallow boxes
within horse shelters
- Bird and bat boxes in woodland
areas
- Survey and monitoring of wildlife
to ensure protected species were not disrupted.
Energy
The zonal earthworks design reduced haulage of materials,
thereby minimising fuel consumption and carbon emissions.
Innovative chemical analysis of materials within the
housing development platform works allowed for quick
turnaround of results and enabled a dig-and-dump operation
rather than excavation and stockpiling in windrows.
This alone saved approximately 30,000 litres of fuel.
Car sharing and energy efficiency in offices was promoted.
Waste minimisation
Earthworks were specifically designed to be spilt
into three distinct zones, with each zone to give a
cut/fill balance. As a result, no material was sent
off site, other than recovered metal, rubber belting
and asbestos.
All hard material discovered during excavation works
was stockpiled and crushed for use as hardcore for pathway
construction.
Community involvement
A community ranger was appointed and monthly community
liaison meetings were attended by contractor and client
team members.
A schools visiting day was organised, attended by over
120 children. The aim of the day was to promote the
scheme and increase safety awareness on construction
sites. Each child planted their own tree and was given
a hi-vis vest and goody bag.
The site office operated an open-door policy to encourage
residents to voice their concerns. Any concerns raised
were actioned immediately.
The project received a Considerate Constructors score
of 37.5 and is unlikely to receive anything less than
a Gold Award.
Innovation
The project made the most of industry best practice
and developed an innovative methodology for the chemical
analysis of materials in an on-site testing lab.
Recycled materials were used to make ameliorant (paper
crumble in lieu of liming and treated sewage sludge
in lieu of compost/topsoil).
