Pathfinder House - Huntingdon
PEP were chosen as part of the Alfred McAlpine (now Carillion) Consortium for this design and build project, to provide a new Headquarters Building and Operations Centre for Huntingdon District Council. Our responsibilities included all civil and structural aspects of the scheme, including external works, foul and storm drainage.
The project required the extensive demolition of a number of existing multi-storey buildings. The piled foundations to these structures, together with various archaeological excavations undertaken on the site, significantly complicated the substructure and external works packages.
The building structures include both steel and reinforced concrete frames, the former utilising composite and hollowcore precast concrete floor planks. The buildings are clad with a combination of masonry, proprietary cladding panels and curtain walling. Foundations are piled.
Project Value: £20.00m
Cambourne Business Park . Cambridge
PEP acted as civil engineering design consultants on this joint development by Development Securities and Wrenbridge Land.
The contractors Alfred McAlpine Special Projects appointed PEP to undertake the infrastructure drainage design to plots 2000, 2010, 2020 and 6010, totalling 6.2 Ha of site. The works included storm drainage, foul drainage, land drainage, pumping stations and all ancillary requirements for the parking, roads, footpaths and feature lakes.
The tree pit and land drainage scheme proposed by PEP solved water logging problems encountered elsewhere on the Business Park.Eastlake Business Park . Milton Keynes
PEP were appointed as civil and structural engineering design consultants for this three phase development at Willan Lake in Milton Keynes, including external works.
Phase 1 comprises a three storey 60 bedroom hotel extension. The building is of traditional load bearing masonry construction, with precast concrete floors and trussed rafter roofs, constructed on piled foundations.
Phases 2 and 3 comprise a total of ten office buildings, each of two or three storeys. The steel framed buildings have precast concrete first floors and are constructed on lightly reinforced foundations, built on made ground improved by vibro-compaction.

Buckingway Business Park . Cambridge
A joint commercial development between Carisbrooke Developments and Alfred McAlpine. The project involved the construction of a series of office units in three phases (6, 8a and 8b), on an existing Business Park north west of Cambridge. PEP were responsible for all civil and structural engineering aspects of the scheme.
External works included roadways and parking areas, pumped storm drainage, land drainage and foul drainage systems.
Building structures comprised traditional trench fill and pad foundations, supporting a combination of loadbearing masonry perimeter walls and internal steel framing. Ground floor slabs were of cast-insitu ground-bearing construction, whilst first floors used hollowcore PC floor units. The roofs were of traditional timber trussed rafter construction.Bell Business Park - Aylesbury
Contractor G. W. Deeley appointed PEP as civil and structural engineering consultants on this Design and Build contract, to provide a development of two and three storey office buildings for Status Bell in Aylesbury.
External works design included determination of finished levels, setting out and construction details for all roadways and parking areas, plus storm and foul drainage systems.
The buildings are of steel framed construction, supporting precast concrete hollowcore floor units to the upper floor levels, and traditional timber trussed rafter roofs. Ground floor slabs utilise cast-insitu ground-bearing construction, and foundations comprise traditional mass concrete pads and strips.

Millbrook Proving Ground . Near Ampthill
PEP have been involved with a number of developments at Millbrook Proving Ground, one of the largest and most comprehensive commercially available Automotive Engineering and Transportation test sites available in Europe today. Projects include:
Twelve cell engine test centre and control rooms, a fuel farm and service station, a new workshop/office unit (block LH), new workshop/offices for Toyota (block LK), new workshop/offices for Vauxhall motors (Block LJ), alterations to crash test laboratories, and works to a new off-road facility.
Global site drainage schemes have also been designed as part of proposed new infrastructure works, including storm water attenuation ponds.
AEA Harwell - Didcot
A multi-phased project to provide business units on the existing Atomic Energy Authority site, re-phased to fall outside of the secure compound. PEP were appointed through contractor G. W. Deeley to provide civil and structural consultancy services.
The proposed development includes 32,000 sq.ft. of steel framed buildings with precast slabs and composite deck concrete floors, plus complete infrastructure works for the entire development.
The refurbishment and conversion of the existing Atomic Energy Authority Library building provides an additional 24,000 sq.ft. of offices. A further 30,000 sq.ft. of office development is also planned
Clarendon Road - Watford
The Terrace Hill Group novated PEP as structural design consultants on this Design and Build contract in Watford. The project entailed the extensive refurbishment of an existing 1970.s era, four storey building to convert it into modern office accommodation.
Works involved stripping away the existing cladding, plus internal fixtures and fittings, to expose the bare concrete frame. The building was then re-clad throughout with a combination of new curtain walling, horizontal cladding panels and terracotta rainscreen.
As part of the structural alterations, the floor area was increased by 10 to 15% by hanging a new external façade beyond the original cladding line. The new facade was supported at roof level on a combination of hot-rolled and cold-rolled structural steel framing, fixed back to the original building structure.
