| CAPABILITIES
- Civil
Engineering

Topographical surveying, ground investigation
and site appraisal, coupled with comprehensive ground modeling
software and the ability to investigate the stability of existing
and proposed slopes, enables WJA
to make a cost-effective assessment of the viability of your project
on your site. Earthworks and imported/exported materials balance for
infrastructure, reclamation or landscaping projects can be
quickly assessed and, where required, transformed into suitable
bills of quantities, design drawings and contract documents.
- Reclamation and Remediation
The Managing Director,
Nick Jackson, has been involved
extensively in reclamation projects, mostly in the old industrial valleys
of South Wales, since 1972. He has been responsible for the design and
supervision of schemes to recover derelict collieries, iron works
and associated waste tips for new industrial development, housing
or amenity use. Many of the sites required remedial measures to
remove pollution. More recently, WJA investigated the old
gasworks in Builth Wells for Powys County
Council and designed and supervised the decontamination and restoration
of the site for commercial or housing development and the construction
of flood alleviation works.
Geotechnical
Engineering
Although essentially
a civil engineering consultant, a major proportion of WJA's work is
geotechnical engineering. A recent example involved successfully bringing
to a halt a major landslide
consisting of nearly 1 million tonnes of soil and rock that at the start
of contract works was moving at 2 to 3 metres a month and threatening
residential properties below. Abandoned mine workings and poor
ground conditions have also been investigated and treated to allow
building developments to proceed.
Hydrology
- WJA
retains a hydrologist with substantial experience in the fields of urban
and land drainage, tidal and fluvial flood protection, river and coastal
engineering, flood hydrology, hydraulic structures, agricultural and development
drainage, flood alleviation benefit assessment and hydrodynamic mathematical
modeling. His experience extends over 35 years.
- Expert
Witness
Nick Jackson has
regularly acted as Expert Witness for Solicitors and other Clients
over the past 17 years, providing engineering support for litigation
or insurance claims or disputes. WJA
is included on the UK Register
of Expert Witnesses. On occasions, more specialist expertise
has been provided in cooperation with academics from the University
of Wales at Cardiff and the University
of Glamorgan.
