Integrated Sustainability
Partitioning 1 – Why ?
• Flexibility: o Add or change with
minimal noise &
disruption
• Sustainabilty o Overcomes functional &
technical obsolescence
o Reusable components
(H-frames)
• Time & cost savings: o No drying time for
brickwork & plaster
o Saving off-sets extra
capex
o LCC = significant cost
benefit
• Practicality o NCBMH is 16 storey
building where access
for wet trade works is
problematic
21
Integrated Sustainability
Partitioning 2 – How? & Lessons learned
• Firewalls in brick: o Drywall detailing
problematic
o Drywall fire sealing difficult
• Design & prebafricate
supports: o Door H-Frames: for heavy
doors, fire doors and sliding
doors
o Sanitary fittings
• Sequence of work changes: 1. Wet trades: screeds &
brickwork & plaster
2. Ceiling services
3. Drywall framing
4. Prefabricated H-frames for
doors and sanware
• Programme changes as a result
both:
o Documentation
o Construction
24
Integrated Sustainability
Wet Services 1
• Flexibility: o Reusable components (H-
frames; composite water
pipe, fittings, brassware,
etc)
• Sustainability o Heat recovery for hot
water
o Sterilized hot water
recovery from autoclaves
and renal care
o Desalination plant
• Time & cost savings: o Capex & opex savings

Integrated Sustainability & Future Proofing
Electrical 1 - Summary
• Sustainability
• Hospital transformers
• Luminaire selection and
lighting systems
• Load monitoring confirms
efficiencies exceed design
estimates by +/- 30%
• Green initiative:
o Standby Generator
installation – noise
suppression
• Future proofing:
o Electrical system designed
for the future expansion
o Plantrooms sized for the
expansion
26
Integrated Sustainability & Future Proofing
Electrical 2 – Extra Low Loss Transformers
o Additional capital cost for the Dry Type (not oil filled)
Extra Low Loss transformers: R243 174
o The savings due to reduced losses estimated at
R48 999/annum (excluding escalation in electricity
costs)
o Simple payback period: 5 years

Electrical 3 – Luminares & lighting systems
Luminaire selection: • LED used to the maximum:
o prices were coming down
o efficiency is going up
• LED lights except T5 recessed 600 x 600
and 1200 x 600mm which was more energy
efficient at that stage
LED Bump Rail Lighting (Night & Emergency)
LED Lighting to the Theatre Corridor

Integrated Sustainability & Future Proofing
Desalination Plant - Background
Background
• Non-viable at project start
• Became viable to mitigate “Day
Zero” scenario risks
• NCBMH Daily demand: 100 000
litres
• Also address the needs of all
Netcare Western Cape facilities
• Total capital cost: +/- R 7 million.
Raw water source – basement
sump:
• “Fresh” water from Table Mountain
side – but dry during drought.
• Underground tidal water –but high
TDS silt-laden salty water.
Capacity:
• 400kL per day
• Tanker filling point
29
Integrated Sustainability & Future Proofing
Desalination Plant - Challenges
• Variable Total Dissolved Solids
(TDS): 4500 - 15000ppm (in drought
conditions). Solution : plant operating
pressures increase from 12 Bar to >
40 Bar.
• Basement Location: posing height
restrictions as well as complexity in
rigging the plant into restricted location
via difficult access route. Solution:
bespoke design.
• Programme:
• 90 Day time frame available to
March 2019 completion date.
• Statutory compliance with: o City of Cape Town, Department
of Water & Sanitation
o Department Environmental
Affairs
o Marine and Coastal
Management

Future Proofing
Helistop Background • Requirement for fully licensed Helistop as
required for a full Level 1 Trauma Facility
• Assists City of Cape Town in bidding for world
class events
Some key definitions • Heliport, Helistop vs Emergency landing zone
Approval process: • Land Management & Town Planning
• National Ports Authority – leading lights & flight
path
• Cape Town Disaster Management – no fly zone
• Civil Aviation Authority
Programme • Complete “roof feature” in Phase 1 Hospital
Opening by December 2016
• Complete Helistop construction during Phase 2
– by December 2017
• Procure and fit out 2018
• Commissioning and flight training 2019 with full
operations now imminent
32
Future Proofing
Organic Growth
Background • Grow from 254 beds at opening to 356
beds once fully developed
• Seemless growth with minimal impact on
operations during construction
• Mitigate technical obsolescence
• Obviate functional obsolescence
Solutions • 8th Floor parking designed to
accommodate future ward
• Organic growth space on floors
immediately adjacent to areas likely to
expand (theatres, plant rooms, ICU’s &
Wards)
• Flexible and re-usable buiiding
components (partitioning, wet services,
Phase 2 – Add Hybrid Lab
Phase 2 – Radiotherapy bunker
Phase 2 – Add 2 Theatres
