A rooftop parking lot was converted into an
indoor kids playground were mother could
leave kids under supervision whilst doing
their shopping. The structure was designed
in lightweight steel frame with a suspended
floor also from lightweight steel frame.
The existing concrete parking lot was close
to its maximum safe design load resulting
in a challenge to built the envisaged facility
whilst staying within the safe structural
limitations of the concrete structure. The
second limitation was the allowable time
for project execution in order to be ready
for the December holiday period. Therefore
the client opted for the LSF solution.
The facility has over purlin insulation,
a high roof height 6m with exposed
LSF trusses to the area below. Cladding
was done in accordance with SANS 517
standard and the internal playrooms were
airbrush painted by artists from England.

The site waste was very low using the LSF
technology, transport costs and volumes
were very low due to the low mass.
The building was insulated using Isover
cavity bat to negate the high Namibian
temperatures during summer. The

Chromadec roof sheeting was utilised
further enhancing the weight saving of the
total structure.
All export arrangements were done by
contracted transporter companies and no
challenges were experienced.
Staying within the save working load of the
existing concrete structure.
This was overcome by designing a LSF
suspended floor system in conjunction
with using laminated steel trusses to reach
the required spans instead of heavy steel
sections.
Getting building materials into the working
area through a multilevel parking lot.
Interlinks with material was off loaded on
ground floor and the carried in by hand
through the parking lots. In some cases
temporary wooden walkways were built
over the existing roof adjacent to the
project and LSF members were then carried
over this walkways into the construction
site.

The structure was designed in lightweight steel frame with a suspended floor.
