1. INTRODUCTION
The project brief, as issued by Gauteng Funding Agency (GFA), was to conduct an initial
assessment of the building condition, services, structural integrity of 75 Fox Street, and to
provide recommendations regarding the repairs and renovations of the buildings.
75 Fox Street is an occupied and functional building. The building has a structurally sound building
frame and suffers only from minor detailing errors, water entry problems and internal and external
service leaks. The building itself is in excellent condition, but requires the local details repaired to
ensure that it stays in a good condition for years to come.
The major maintenance items include the replacement of skylights and possible internal staircase
corrections.
The condition of the structural components is described below.
Design Criteria and Specifications
This project will be implemented in compliance with all the requirements of the National
Building Regulations and the new SANS10400, including any town planning prescripts of the
local authority.
Scope of the Services Scheme Report
This report deals with the proposed structural services to be implemented and preliminary
design for the feasibility for the repairs and renovations of the existing buildings.
2. STRUCTURAL ASSESSMENT
2.1 Building configuration and interfaces with adjacent buildings 75 Fox Street building comprises 14 floors, 3 basements below ground, ground floor slab, 9
Floors and a roof slab system with local level differences.
The building has a partial concrete roofs at level 14 and portions of the 13th floor is external (roof
area).
The building has a number of feature balconies and gardens on the northern and southern
facades at various slab levels.
75 Fox Street has no links to adjacent buildings.
2.2 Facade
The existing façade comprises a marble cladding on a structural steel sub-frame fixed onto the
concrete structural frame. The marble cladding is in excellent condition; however the renewal of
the polyurethane joint sealer between the panels is required. In two local positions (above the
southern parking entrance) the cladding panels will need to be re-adjusted. On the northern
façade a missing cladding tile needs to be replaced.
Aluminium windows are included in the façade and are in excellent condition. The window
rubbers between the glazing and the frame have perished in certain locations on the north and
eastern facades and need to be replaced.

The facade parapets are covered with steel panel sheet flashing. These panel junctions need to
be resealed. The steel sheets have been blown off in a number of locations and require
replacement and joint resealing.
The vertical walls above roof level are in need of maintenance (painting) to avoid future damage
of facades and occupancy below roof level.
It is suggested that the external pavements around the building are lifted, levelled and re-laid as
the trees and other damage has caused the walking surface to become uneven and is a tripping
hazard in certain areas.
A window cleaning system exists for cleaning the exterior windows. The rail system is in good
condition; however the mechanical components must be checked by the mechanical engineers.
2.3 Roof Waterproofing and Roof Structures
The flat concrete roof system consists of a stepped roof arrangement over 3 floor levels.
The roof system has occupied floor areas, entertainment area, plant and general roof areas.
There is no plant visible on the roof as it is housed in dedicated covered areas.
The roof is generally covered in a varied size stone aggregate layer, underlain by a damp proof
membrane covering the roof waterproofing. The roof appears to be waterproofed with a
combination of acrylic roof sealant and torch on waterproofing in respective areas.
The majority of areas have recently been recoated in acrylic sealant and is in excellent condition.
There have been reports of water leaks under the new waterproofing in local areas, hence local
repairs of the waterproofing should be allowed for. Allow 10% of the roof area for such repairs.
Under the waterproofing is a screed to fall to fulbore outlets and associate downpipes. The
screed and downpipes are in good working order.
The following concerns need to be addressed with regard to the roof coverings:
1. The stone aggregate layer was not washed when installed and hence there is a layer of
fine material above the waterproofing which has the potential for clodding rainwater
goods and keeping the waterproof surface damp.
2. The stone layer stone size is too small and is being washed into the downpipes and
possibly damaging the downpipes internally in the process and leaking to blockages
down the line.
3. The presence of a damp proof membrane above the waterproofing in certain areas traps
water on the waterproofed surface and hence increases the risk of leaking.
4. Loose laid external pavers require edge restraint to prevent edge breakage.
5. Tiled external areas and skirtings need to be locally repaired and resealed to eliminate
water penetration into the structure.
6. External entrance door to the western fire escape should be covered with a
weatherproof awning.
7. Central skylight to be refurbished/replaced.
8. Central skylight louvres orientation to be corrected to direct storm water outside the
building.
9. Sloping skylight adjacent to the central skylight must be resealed.
Report for Department of Infrastructure Development Services Preliminary Report: 75 Fox Street August 2014

10. Entertainment area soft roof requires a gutter system on its lower end to avoid rain
water falling onto the incorrectly orientated louvres of the central skylight.
11. Roof façade walls which are plastered and painted are to be repainted
12. Façade render to be corrected and repaired locally where identified.
13. Safety hooks on the roof need to be replaced with more recent technology fasteners to
comply with latest safety standards.
There is a roof cleaning system with complete structural steel track system. The track system will
require repainting, and the lifting system will require mechanical and electrical check.
All structural steel elements on the roof require de-rusting and repainting.
2.4 General Structural Floor Slab Assessment
In general the existing concrete slab structures are in excellent condition.
The coffer slab construction of the floors from ground up and the flat slab construction of the
basements are all in excellent conditions.
No remedial works are required on the main floor slabs except for the following local issues:
1. Movement joint treatments to be addressed. In the parking slab situation the edges of
the movement joints are chipping and degrading as there is no edge protection. The use
of a steel plate secured on the one side of the movement joint is recommended, or a
suitable architectural joint treatment that can accommodate 20mm structural
movement. In the office ceiling situation, the plaster render must be treated with a
cover strip consistently secured on one side of the joint to cover the joint in the render
to architects details.
2. Replacing of the main southern entrance ramp (ground floor) mentis grating and the
cleaning out of the drainage channel.
3. Replacing of a local portion of screed, centrally on the south façade of basement 1 is
required.
2.5 Structural Column and Concrete Wall Assessment
The building is supported by concrete columns and concrete core walls which are in excellent
condition.
2.6 Foundations The building shows no signs of settlement and hence foundations and bearing strata below are
in good condition.
2.7 Basement and Basement Retaining Walls
The building has three sub-terrainian basements. The basements are in excellent condition
except for the following local defects:
1. Water leak from surface ponding through the basement 1 slab to basement 2 below on
the central southern façade. The replacement of the screed on basement 1 will solve the
problem.
2. Local patches of horizontal water entry through the basement walls. The solution is to
solve the leaking water pipe in Commissioner Street on the adjacent property, as well as
applying local negative waterproofing in local areas. Allow 50m2 of negative
waterproofing.

The basement as two sump pumps which have recently been replaced and are in excellent
condition.
2.8 Building Internal Brickwork
The building’s internal brick walls are in excellent condition. There are a number of internal walls
with superficial cracking, but these can be filled with polyfiller (or similar) and repainted as
required.
In the basement archive, there is a portion of plaster that is peeling off the walls due to a water
leak. Details are in the photo evidence.
2.9 Building Internal Finishes and Services
The building internal finishes and services are in good condition.
Refer to architects report in this regard.
2.10 Staircases
The building has three concrete internal circulation staircases and two structural steel fire
escape stairs, one internal and one external.
The internal concrete stairs are structurally sound and the handrail and surface finish are in
excellent condition.
The internal structural steel fire escape staircase is in excellent condition; however the stair
geometry as built is does not meet current building regulations. The stair length is thread is too
short and the stair inclination appears excessive. It is recommended that this stair is
reconfigured for easier and safer use.
The external steel fire escape is in good condition, but will require local de rusting and a
complete repaint.
For the staircase compliance with new SANS regulations refer to the fire engineer report.
2.11 Structural Floor Loading Allowances Allowed For Future Use
Office and reception areas: 350kg/m2 (Office occupancy + light weight partitions)
Parking: 200kg/m2 (Car parking (no trucks))
Roof Slabs 350kg/m2. All new mechanical plant is best accommodated in existing plant rooms.
Plant Rooms (All floors): 500kg/m2 .
Note no masonry brickwork partitions are allowed internally and externally, unless verified by
structural engineer. In general walls which are required to be masonry (that is bathrooms and
kitchens) already exist.

Figure 5: Roof stone chip layer is maximum 30mm thick and was not washed when installed.
The result is a layer of fines on the waterproofing which will retain moisture and
contribute to clogging of rainwater drainage paths and roof leaks.
Figure 6: External roof tiling tile grout has been placed on a Damp proof membrane. This is a
structurally acceptable detail; however the tiles should be secured on the edges of
the tiled areas to avoid the paving surface breaking out at the edges.

Figure 7: A Damp proof membrane is placed over the waterproofing under tiling and stone
chips this plastic sheet will retain moisture between the sheet and the
waterproofing causing leaks. The use of a nonwoven geotextile is preferred as the
fabric is porous and can dry out, and offers better protection to the waterproofing
from human traffic above. In addition the stone chip size is too small and can easily
be washed into the rainwater downpipes causing damage to the pipes.
Figure 8: South eastern corner of the building showing well maintained roof. A maintenance
schedule and local patching may be required. It is noted that the roof waterproofing
is a mixture of torch on waterproofing and an acrylic based waterproofing product.
It is suggested that one system is standardised and used throughout for future
maintenance.
