Following 25 years as a Structural and
Civil Engineer in the construction industry, George Voyias formed Ashton
Consulting Engineers in November 2007. George has extensive experience
in the design of many new buildings in the commercial, educational,
health, residential and industrial sectors. He also has great experience
in assessment and conservation of existing Listed, historical and modern
buildings. Below is general information on the practice and examples of
some of the projects George has engineered.
The aims of Ashton Consulting Engineers
(ACE) are to provide a quality service to clients by ensuring each
client’s objectives are defined and realized. ACE strive to give
proactive design advice working in close collaboration with the client’s
architect and other professional consultants. Careful attention is given
to the co-ordination between disciplines to achieve integrated design
solutions that are within budget and programme. ACE are able service
projects throughout East Anglia as well as north and central London.
George has the support of several other
engineers and CAD technicians to provide design, drafting and site
supervision assistance. George has worked with these engineers and CAD
technicians for many years and he has full confidence in their ability
and support. In addition ACE have arranged an inter-office agreement
with a larger practice to pool staff resources for larger projects.
George is a member of the following professional institutions and
- The Engineering Council, UK (Chartered Engineer)
- The Institution of Civil Engineers
- The Institution of Structural Engineers
- The Society for the Protection of Ancient Buildings
Ashton Consulting Engineers are committed
to the aims and standards of the Association of Consulting Engineers.
PROFESSIONAL INDEMNITY INSURANCE
The practice offers professional
indemnity insurance cover of £2.0 million as standard for most projects
and this can be increased to suit larger projects.
West Court, Clare Hall, Cambridge
New accommodation buildings were provided for visiting fellows and
study bedrooms for students of Clare Hall, a graduate college of
Cambridge University. The layout created a new quad against a large
house designed by Erskine in the 1960s. The structure consists of steel
and timber roof trusses, timber rafters, as well as pre-cast hollow-core
floor slabs, supported on load-bearing masonry built on trench-fill,
in-situ concrete foundations.
The project was awarded a Civic Trust Award
in 2003. The judges described the scale and relationship of the
development to its neighbour as so successful that it added to the
quality of the original building. The interiors are bright, colourful
and well detailed, with excellent circulation spaces.
New Offices & Laboratories
The Generics Group, Harston
The sensitively designed scheme has 4000 square metres of floor
space, a new junction for access onto the A10 road set in landscaped
parkland, a reduced level car park, and a sustainable urban drainage
The new buildings have prefabricated
steelwork frames and precast concrete floor slabs. One new module has
piled foundations in Gault Clay, while the other four have conventional
concrete pad foundations on chalk. The waveform roof has a structural
steel decking infilled with concrete, which is integrated with a
"chilled beam" system of air conditioning, heating and lighting. A
column free space was achieved at first floor level by steel “bow
string” trusses tensioned with stainless steel tie rods.
Orbital 25, Watford
This is one of eight blocks on the site with each block having up to
10 units. 7 of the blocks are complete and the last one is due for
completion in the spring of 2008. George Voyias was Project Engineer
responsible for the design of all the structural work as well as the
roads and drainage.
The units have a steel framing with
reinforced concrete ground bearing slabs and a composite concrete first
floor slab cast on profiled metal decking. The first floor levels have
either a complete floor for office use or a mezzanine floor for both
office and storage space. The storage space at first floor has been
designed to support an imposed loading of 5.0kN/square metre.
New Hall College, Cambridge
This new building for a college of the University of Cambridge has 35
study bedrooms, student common rooms, an auditorium in the basement and
two seminar rooms. The biggest design challenge was to allow for the
construction of the three-storey building with a basement on a very
small site and in a 12 month period.
The solution was to prefabricate almost all
the main structure as well as the bathrooms. This involved the use of
pre-stressed, hollow-core concrete floor slabs, pre-cast concrete
columns, pre-cast concrete stair and landing units, prefabricated
steelwork girder beams and columns, as well as 35 prefabricated fully
fitted and finished bathroom units. The construction cost was £3.1
million and it was completed on time.
Babraham Institute, Cambridge
This state-of-the art laboratory building was built as part of a
£14million redevelopment project of the research institute. The four
storey building has a concrete frame with shear walls to provide a very
stiff building to suit the sensitive laboratory equipment.
The building was designed to give
considerable flexibility in the use of the space to allow for future
research demands while aiming to achieving low life-cycle costs. The
entire third floor has specialist plant and equipment to service the
Jesus College, Cambridge
Structural alterations and repairs were designed for several of the
Staircase Blocks as well as the conversion of the former library to
study bedrooms for this Grade 2 Listed building in the heart of
During the works 15th Century load-bearing oak studs were exposed
that had rotten bases. The rotten timber was carefully cut out and the
stud wall underpinned with engineering brickwork and concrete footings.
Other structural repairs included
strengthening the timber roofs, brickwork, stonework and beam and pot
