CONSTRUCTION WORLD

PROJECTS AND CONTRACTS

The tender for engineering services was

awarded to SMEC’s Cape Town office by

the South African National Roads Agency

SOC Ltd (SANRAL) in 2009. This included inves-

tigations, design and construction monitoring.

Mynhardt Augustyn, function manager for

construction and pavements in Cape Town, has

been involved with the project since tender stage

as design leader. Ivan Jacobs, regional manager

for the Free State region, assumed the duties of

contract engineer during the construction stage.

Five technical staff members from SMEC

South Africa were employed on-site full time

for the duration of the project, including three

engineers assisting resident engineer Neels de

Jager, and a senior materials technician. Fernando

Pequenino, section manager for geotechnics in

Johannesburg, was involved during the design,

attending to geotechnical matters during the

construction period.

The existing road, which consisted of a

As the only surviving example of a Victorian Theatre

in Africa, leading specialists in the construction, reno-

vation and recycling of buildings, GVK-Siya Zama,

were enlisted to ensure that it would be preserved for future

generations to enjoy.

When the PE Opera House opened, it was dubbed by press

as ‘The finest theatre in all the World’. However over the course

of its 124 year history, the building and a number of its unique

elements have decayed. GVK-Siya Zama was tasked with

preserving its historic architectural features, while at the same

time expanding its facilities with modern twists.

The building, known as the ‘Old Lady’, houses two theatres:

The Barn, which is a cabaret venue, and the Main Stage, which

was built for ballet, opera and musicals. The upgrade called for

the addition of a dedicated foyer space and passenger lift in

The Barn as well as extensions to the theatre. The Main Stage

required renovations to its foyer along with internal and external

painting and damp damage repairs. Carpets and wallpapering

throughout the building had to be replaced and new air-con-

ditioning, lighting, fire detection and ventilation systems had

to be installed to ensure compliance with the latest building

and energy regulations. Access for disabled persons also had

to be improved. All of this had to be carried out whilst retaining

N7 UPGRADE PROJECT COMPLETED SUCCESSFULLY

South Africa has successfully

delivered a project to upgrade

and improve Section 3 of the N7

between the Western Cape and

Namibia. This 27,7 km stretch

runs between the Citrusdal and

Cederberg intersections.

surfaced width of 6,6 m with narrow gravel

shoulders, was upgraded to SANRAL’s stan-

dard cross-section of 12,4 m surfaced width.

Jurgen Oosthuyse, engineer: construction and

pavements, SMEC South Africa, says the main

challenge faced by the project was that the

existing roadway had considerable vertical align-

ment inadequacies.

“Over the full length of the road, the Olifants

River runs on the eastern side of the road reserve,

with valleys created by watercourses crossing the

roadway at regular intervals. The existing roadway

followed the contours of these rolling hills closely

and reduced sight distance to the point where

passing was impossible,” Oosthuyse explains.

To this extent, the standard of the vertical

alignment was improved by constructing

numerous large fills using material obtained

from cuttings, a total of 650 000 m³ of material.

Improving horizontal alignment at two major

watercourse crossings required the construction

of two bridges. In addition, 12 major on-site

culverts, as well as several smaller culverts, were

required to provide sufficient infrastructure for

drainage requirements.

A hard-rock quarry was established to produce

approximately 175 000 m³ of crushed material for

use in the pavement layers, for stone in concrete,

as well as for use in stone pitching to erosion

protection works.

The project provided unique challenges

in meeting conflicting demands for traffic

accommodation, keeping hauling distances to

the minimum, and ensuring that available cut

materials were put to best use as dictated by their

engineering properties.

The geology consists of sandstone dipping

towards the road with varying strike, mostly

perpendicular to the road. The sandstone forma-

tion included interbedded clay layers, resulting

in a number of slope failures in places during

construction, and which were stabilised using

rock bolts and mesh.

and protecting as much of the fragile original heritage elements – from

pressed ceilings and tiles to ornate fretwork – as possible.

Barend Delport, regional managing director at GVK-Siya Zama, says

that some the most interesting components of the project were the

reconstruction of the original gallery floor to increase seating capacity

and the installation of an all-new fire escape route.

Delport believes that the revamped PE Opera house now provides PE

and its residents with a first class facility that will attract local and inter-

national acts. Once more funds are secured, the ‘Old Lady’ will house a

rotating restaurant, modern stage, roof garden and opera school.

ENCORE FOR AFRICA’S OLDEST THEATRE

The oldest theatre on the African continent

and in the Southern Hemisphere, the PE Opera

House, has recently undergone intricate

renovations and expansions. This was done

to transform the building from a heritage site

into a first class facility.
