Background

During

2013,

AESL

carried

out

a

scheduled

on

AESL

has

already

submitted

a

on t}Ie

to

the

to provide

AESL,

as

such was primarily

responsible

for

as

well

as

the

fire

systems.

The last

inspection

was

conducted

oD tie

31st

ofAugust,

2012.

In

carrying out

this

review

exercise,

information

was

gathered

by

condocting

visual

inspection,

reviewing

previous

studies

and

interviewing

stadium

operations

personnel.

In

addition

to t}Ie

review

of the coating

condition

throughout

the

stadium

bowl,

AESL perforrned

limited

in-depth

studies

of distressed

coating

areas.

These

studies

were

used

to

gain

a

better

assessment

ofthe particular

obsewed

condition.

It

must

be

emphasised

here that.

choosing

reinforced

concrete

as

a

construction

mate

al

would

have

perfor[red

better

as

compared

to

the

structural

steel

ooted

for

in

the

design

in view

ofthe

proximity

of

tie

facility

to the

sea.

The

stadium

is

situated

in

an

cnvironment

of

high

humidit"v

and

winds

laden

rvith

saits

which

are

congenial

to corrosion

ofthe

structural

steel

elements.

It

has

been

revealed

that

t}1e structrllal

steel

were

not

given

The

Our

findings

from

the

recent

assessment,

revealed

that

most

of

tie

raised

in

the previous

are

yet

to

be

addressed,

with

the

exception

of tie

had

been

applied

to

The

Lrspection

showed

Obsewing

The

As

concludes

that

loadings,

and

tiat

there

was

no

danger

However,

AESL

that,

If nothing

be enhanced

by

introducing a DAT

suoh

that

their

The curent

according

to the

They complain

that

the septic

The
