Tight construction schedule for realisation of modern business centre

02/11/2011 | Ocean Plaza Business Centre, Kiev, Ukraine

With a comprehensive formwork and scaffolding solution, PERI´s Ukrainian engineers are supporting an ambitious building project in downtown Kiev. In order to ensure that work is completed in time for the start of the European Football Championship in July 2012, an extremely tight schedule for the structural work has to be maintained. Not only the most appropriate system equipment with optimal material requirements is contributing to the success of the project but also expert advice and support provided throughout all phases of construction.

Ukraine is currently gearing up – along with Poland – for the 2012 European Football Championship. Along with modernizing the metropolis and capital Kiev and upgrade of the Olympic stadium, the redevelopment programme also includes the opening of the "Ocean Plaza" – a new business centre in a prime downtown location – to coincide with the start of the tournament. Not far from the stadium and historic old town, this modern complex with a total of 250,000 m² of floor space and 3,000 underground parking spaces is being realised in three construction stages. In addition to a hotel chain, cinemas and restaurants, the retail trade in particular will be the main focal point. In the process, one, two and three-storey storefronts are available for future tenants and visitors.

Optimal system equipment for columns, walls and slabs

The floor slabs of the four story building are supported by reinforced concrete columns with 70 cm diameters or edge lengths respectively. For this, the construction site team is using SRS circular column formwork for the round cross sections and TRIO column formwork for the square shaped columns. Especially advantageous is the fact that the TRIO column formwork system can be combined with TRIO wall formwork at any time. This has ensured fast forming of the different wall section heights – with few individual components and the BFD alignment coupler as the only connecting part required for all panel joints.

The usually 30 cm thick reinforced concrete slabs are being formed using the MULTIFLEX girder slab formwork with support provided for the standard 3 m floor heights by means of PEP 20 and MULTIPROP props. The MULTIPROP props are made of aluminium and have a low weight but a high load-bearing capacity. In those areas where loads have to be transferred over great heights, the individual props are connected with MULTIPROP frames thus forming a modular shoring tower system.

Flexible load-carrying concept

The new building complex complete with multi-storey retail units features countless height offsets and cantilevered areas. This means supporting heights are required ranging from two to four floors; furthermore, the largely column free architecture is a result of load distribution via massive downstand beams. With PERI UP Rosett, the construction team has a highly flexible shoring system at its disposal. Shoring towers with1.50 m and 2.00 m base widths have been assembled which have been adapted to suit both the respective supporting height and load to be carried and, if necessary, extended by means of additional frames. In areas with large supporting heights up to 13.80 m, a spatial load bearing structure is used to transfer the loads. For adapting the shoring to accommodate area loads and concentrated loads – resulting from 1.20 m thick beams – 50 cm and 75 cm horizontal ledgers are used. Thus, the standards are bundled within the system which means that time consuming tube and coupler assembly is not required. Cantilevered brackets in the load carrying system support the GT 24 and VT 20K formwork girders in those positions where additional working space is needed at the slab edges.

Comprehensive service

Close consultation with the site management team also during the tendering phase meant that formwork and scaffolding requirements were analysed together and the system equipment individually tailored to meet project demands. This resulted in the most cost effective construction solution whilst taking into account both time and costs. PERI engineers have been available throughout the entire construction period to deal with all technical and logistical support issues and will continue to do so up to the completion of the project. The close collaboration and comprehensive support – from the planning phase through to return deliveries of materials – ensures the best possible results on the construction site as well as continuous operating sequences without any interruptions.
