BREEAM OUTSTANDING ACCREDITED HOSPITAL

MISSION STATEMENT

The building design and engineering strategy follows the needs of a 21st century healthcare facility

providing a therapeutic environment that promotes health and well-being, is patient orientated,

intuitive and flexible to future needs. The aim is to design a positive impact building that uses fewer

resources, generates less waste, curbs CO2 emissions and to save the NHS money over its life-cycle.

All wash basins are sensor operated

All surfaces, floors and walls have an easy clean, durable

hygienic surface coating.

MECHANICAL SERVICES

9 Air Handling Units have been selected to

provide all occupied rooms with the option

of mechanical ventilation.

Ultra Clean Ventilation system used within

the operating theatres for infection control.

10kW ground source heat pump used for

under-floor heating in atrium.

10000L GRP Storage Tank stores sufficient

water to supply 24 hour requirements.

460kW gas fired, condensing boiler selected

as the primary method of heating water.

External VIE has been sized to store

3927L of oxygen at -160C.

ELECTRICAL SERVICES:

Calculated power requirement of

210kVA, supplied by LV DNO connection.

Standby generator provides backup to the

essential areas of the hospital.

Solar shading system tracks the sun and

collects electricity via PV technology.

62 PV panels installed on the roof.

Fibre optic cables draw natural light down

into corridors.

ESTIMATED CAPITAL COST: 7.92M Cost per square metre: 1494

SUPERSTRUCTURE:

Cast-in-situ reinforced concrete frame.

C50/60 concrete mix with a 50% GGBS

content specified.

Flat slab design offers maximum flexibility in layout.

Slabs designed using the yield-line method.

The structure is braced by concrete shear walls incorporated into lift cores.

Steel sections have been utilized in the atrium to provide long spans of column free space.

SUBSTRUCTURE:

CFA piles are to be utilized due to their low noise and vibration installation.

144 CFA piles (450mm diameter) are to be installed to a depth of 23 metres.

Floor slabs are to be ground bearing.

PROJECT COSTS:

BREEAM Rating: 85.2%.

ARCHITECTURAL CONCEPTS:

The hospital layout is designed around clinical adjacencies to ensure it is highly

functional.

Patient orientated design that promotes health and wellbeing.

Intuitive layout reduces the stresses of wayfinding within the hospital.

Wherever possible natural daylight is introduced and views to the outside are

provided.

The facade design follows a modern, simple and efficient statement design.

Each floor is divided into 3 main fire compartments. Each compartment has

two independent escape routes

25% Green Space.

INFECTION CONTROL:

Inpatient and outpatient departments separated.

Clean and dirty corridors provided for operating theatres.

High ventilation rates throughout patient areas prevent airborne transmission.

SUSTAINABILITY:

Narrow plan design reduces energy costs.

Rainwater harvesting for toilet flushing and irrigation.

Locally sourced materials & labour specified.

Extensive green roof.

Building management system optimises the use of services.

Flexible for future developments in medical science

or management.
