Figure 10. Construction Works Perimeter and Layout
4.1. Work Areas
There are 7 identified work areas:
1. Shop 17 Substation
2. New LV Switch Room
3. Portside Penstock Filling Valve Shaft
4. Starboard Penstock Filling Valve Shaft
5. Outer Dock Dewatering Valve Shaft
6. Dewatering Valve Shaft
7. Pump House & Comedy Club
The work areas shall each be individually barricaded using highly visible pedestrian barricades and access
will be tightly controlled by a work area specific safety representative. In the case of any digging or
trenching, care will be taken that this work is undertaken outside business hours and any unfinished work is
clearly marked, covered and /or barricaded against during business hours.
All persons working in the worksites will be provided with highly visible personal protective equipment (PPE)
clearly marked with the responsible contractor’s logo.

Although most of the work that will be carried out in the pump house will be underground; there is a
requirement to modify the pump house roof, which also serves as a comedy club floor. To carry out the
work the comedy club will be closed and locked out for the public. It is therefore the project’s intension to
minimize the amount of time the comedy club will be closed (currently estimated at 3 days). The
management of the club shall notified well in advance so as to plan accordingly for the shut.
In addition there will be a number of equipment deliveries into the pump house that will require the access
hatch in the comedy club for rigging purposes. This work will be carried out outside the comedy club
business hours, however assistance will be required from the management
4.3. Contractors’ Laydown Area
All contractors shall establish site within the dock perimeter on the portside of the dock basin as shown in
figure 9. The contractors shall ensure that all their requirements, including workshop, offices, mess and
ablutions are within the allocated space.
4.4. Visitor Parking
TNPA project team, V&A team and other corporate visitors shall be provided with parking as shown and will
use the existing TNPA mess and ablutions when needed.
4.5. Delivery Traffic Flow
Access to site is via Dock Road, to access contractor’s lay down area. Contractors shall the passage
between the dock and the aquarium, and to access the shop 17 and pump house work area one will use the
passage between the watershed and the comedy club.
It is not expected that there will be abnormal load deliveries during the construction period, therefore there
isn’t any special permits to be requested from the City of Cape Town. However for the purpose of
minimizing interference with the V&A’s clientele, it is recommended that all construction deliveries be carried
out outside business hours (18h00 – 06h00).
4.6. Construction Traffic Flow
The construction personnel traffic flow is shown in brown, and will be as a result construction activities. This
traffic will be kept to a minimum and will be monitored by the construction safety agent. This is so that
there will be minimal intrusion of the construction on the day by day business of the V&A Waterfront.
