SUMMARY SPECIFICATION
A NEW OFFICE/LAB BUILDING FOR DALES MANOR BUSINESS PARK
A new bio-tech Laboratories / Office development (Use class E) with associated landscaping and decked car park is proposed on a site at Dales Manor Business Park, Sawston situated in what is currently a light industrial area on the northern edge of Sawston adjacent to the Green Belt.
Embracing the principles of the Life Sciences and Biomedical parks, our planned development aims to integrate harmoniously with the natural landscape, offering a serene atmosphere for work and inspiration. A net carbon-zero development that prioritizes connectivity, efficiency, and the future of work.
THE SITE
To the northeast the site is screened from the Green Belt beyond by a mature hedgerow and bounded on all other sides by neighbouring industrial development.
The future CSET route to the northeast boundary provides a superb opportunity to connect this plot and the wider business park to the surrounding Life-science and Bio-tech cluster.
DEVELOPMENT APPROACH AND PROPOSALS
Landscape and amenity space are critical to a building of this type and location and this functional & flexible Lab/Office design has been shaped and informed by the landscape with an appropriate scale of development and massing. Promoting active travel and creating exemplar facilities we are delivering a Net Carbon Zero development with a highly flexible building design.
BENCHMARKING AND ACCREDITATION TARGETS
Energy Performance Certificate (EPC) rating of A.
BREEAM Excellent.
WiredScore Platinum.
SmartScore Enabled.
Operational and Embodied Carbon assessed in accordance with UKGBC standards.
Cycling Score Platinum.
A summary of the development scope pertinent to this site is as follows:

Tenant space available for future services.
SERVICE YARD
Space available for generators.
Direct access from loading bay and Utility Store.
UTILITY STORE
Compressed gases store : Aproximately 80 cylinders.
Chemical Store : 2Nr.
Bin Store: 24 x 1280L = 30,720L.
SUPERSTRUCTURE:
RC Flat slabs (typically 400mm in thickness without any drop panels) are supported on an arrangement of 600x250 RC columns (generally on a 7.2m x 6m grid spacing) and 250mm thick RC shear walls located around the stairs, lift enclosures and other discrete locations within the building.
The stairs will be formed in precast concrete construction.
Building services are generally routed below the slab soffits and are integrated within the RC shear walls where necessary via a series of preformed openings. Risers (typically 1750mm x 1200mm) are distributed across the floor plate to facilitate the vertical distribution of services throughout the height of the building.
The fire resistance period for the building structure is 60 minutes.
All elements are to be designed to the Eurocodes and their respective UK National Annexes.
TYPICAL FLOOR IMPOSED LOADINGS
| Roof Slab Areas | KN/m2 |
|---|---|
| Plant designated areas | 7.500 |
| Laboratory & Office Floors | KN/m2 |
| Laboratory/Offices | 3.000 |
| Partitions | 1.200 |
TOLERANCES AND DEFLECTIONS
Individual member deflections are limited to values in Eurocode 2 –span/250mm for total overall deflections and span/500mm for deflections arising post cladding installation.
Overall horizontal building movements are limited to height/500mm, and individual storey drifts are limited to height/400mm.
Construction Tolerances are to be in accordance with NSCS, National Structural Concrete Specification.
VIBRATION PERFORMANCE
The suspended floor slabs at Level 01 and Level 02 are to be designed to deliver vibration target performance of VC-A (or better) across the vast majority of the floor plates.
The floor will be adequate in most instances for optical microscopes to 400X, microbalances, optical balances, proximity and projection aligners.
