PETER MOKABA STADIUM (NIGHT SHOT 22 OCTOBER 2009)

CHALENGES ENCOUNTERED AND ANTICIPATED

• Key Material Procurement• Labor unrest• Skills shortage• Dealing with FIFA specifications• Budget and deadline• Methodology to construct the stadium

HOW WE OVERCAME THE CHALLENGES

• MATERIAL PROCUREMENT1. We purchased almost all the required reinforcing in

stock length2. Checked the quarries if they had enough

aggregates and checked their other commitments.3. We never used a quarry for backfilling, we reused all

material by crushing and screening 4. Various meetings with the professional team,

helped in making sure that most of the material/equipment to be used was locally available

HOW WE OVERCAME THE CHALLENGES (cont’d)

• LABOUR UNRESTS1. There was unrest that threatened completion, PLA was in

place and amended to the labour’s needs2. Bonus incentives were put in place3. With the help of the LOC, free tickets to workers were issued

• SKILLS SHORTAGE1. We trained most of our core labour force and that of the

locals on a regular basis.2. We never experienced it that much except where the key

staff was stretched.3. This stadium was built by an all South African team. The

professional and construction teams were all locally based.

DEALING WITH FIFA SPECIFICATIONS

• The structural engineer and the architectural teams had teamed up with companies that had built stadiums before

• Interface meeting were held to ascertain specifications required by FIFA

• The specifications were requested to be issued early so we could familiarize ourselves with them

CONSTRUCTION METHODOLOGY

• The stadium has two tiers, formed of raking beams, y-columns and slabs in between levels

• We had special shutters designed to form non standard sizes

• Raking beams, which were traditional pre-cast elements, were constructed in-situ

• Seating planks were also pre-cast • Pre-casting some of these major elements

saved us time and cost• Stadium design was in a way that made

cranage positioning easier

BUDGET AND DEADLINE

• Through the innovations we made as a team, we managed to save time.

• Being wise in material procurement and crushing and screening on site, a considerable cost saving ensue as we did not buy any commercial material

• Cost saving in not to source and rehab a quarry.

• In-situ versus pre-cast elements also helped in saving on time

KEY STATISTICS OF THE STADIUM• Reinforcing steel used – 7300 tons• Bricks used 3 million• Concrete used 69 000 cubes• Structural steel 1 300 tons• Stadium seating 46 000• Materials procured locally 95%STADIUM TEAM1.
