The Precinct Lifestyle Hub
ARCHITECTURAL CATEGORY WINNER
With the housing market in decline Century Property Developments diverted their business model into the rental game . To attract tenants to their new development , The Precinct , a lifestyle hub was commissioned . The building features a movie theatre , spa , games room , restaurant , and gym . All with the intent to ensure Century Property Developments rental portfolio is the most attractive to clients in the Midrand Area .
Structural Frame and Challenges The structure consists of a portal frame structure fabricated using universal beams with two floor levels which use universal beams to support various types of concrete floors . To reduce cost and maintain feasibility of the entire project , various slab interactions were utilised . Hollow core technology combined with a composite slab was used . The front portal extended down to the lower ground floor ; thus , the steel work was required to be constructed in various phases . Allowing for access to pack the hollow core slabs meant structural steel columns had to be erected without the portals , following the packing of the slabs the portals could be completed .
The bridge connecting Building 2 to Building 3 was designed using 3D scan technology . This was to maintain the natural koppie and ensure the design best aligned with the rock features . This bridge was constructed from the top down - the walkway propped and installed , the columns installed and then the foundations cast . This was to ensure the bridge aligned perfectly with the footings and touched the earth lightly limiting the environmental impact of the construction . The extensive spans obtained by the hollow core slabs for the ground floor above the cinema are one of the most impressive features of the structure .
Benefit of using steel
• Ability to save time with manufacture off-site ;
• The industrial look obtained from exposed portal frames . The exposed steel lends itself to challenging aesthetic decisions . The building is honest in its structure and architectural intent ;
• All connections , joints and interactions required careful consideration to ensure the final product was in line with the architectural requirements .
Teamwork The original steel contractor went under and Tass Engineering got involved in the project very late and had to expedite the detailing , supply , manufacture , delivery and erection in order to ensure that a quality product was handed over on time to ensure the success of the housing estate completion . The coordination amongst the slab installers , Tass Engineering and century property development excelled to ensure a successful project .
