The main contractor for Bahrain’s King Hamad General Hospital, the Nass Burham Joint Venture has started construction in a 27 month contract, with Nass Contracting taking delivery of nine Dynapac vibratory pokers – in readiness for the first slab concrete pours scheduled for the end of November. It forms part of a first phase package comprising three electronic drive AX56’s and two units each AA27, AA37 and AA47 petrol-driven vibratory pokers, together with Dynapac pokers transferred from other Nass projects in Bahrain. The order was placed following earlier success by Nass on a desalination project in Bahrain where a mix of 27 mm – 70 mm diameter pokers including AM15, AM21 and high frequency converters with AX56 pokers were used for heavy concrete lining of a seawater canal. Delivered earlier this year, it was Nass Contracting’s first experience with the electric driven AX56 – using one UF81 converter and up to four pokers. “We were very impressed with the improved finish of the concrete with the Dynapac poker able to vibrate over a 100 mm distance, eliminating any air bubbles,” said Nass Contracting Construction Manager, Mr Mustapha. King Hamad Hospital The King Hamad Hospital is located North of Shaik Isa Bin Salman causeway in Muharag and will include 312 beds when it opens as a secondary general and teaching hospital. Featuring four floors the project will include three buildings providing a total built-up area of 62,000 m² on a 227,000 m² site. Working a 7.2 m x 7.2 m grid system across the three blocks, Nass will be paving a 150 mm slab using C40/45 grade concrete. Throughout the concrete pours, the Dynapac vibratory pokers will ensure the elimination of any air bubbles. Completion of the first floor slab is expected to be completed by the end of January 2007. When complete, level 1 of the new hospital will include a covered car park for 80 cars and an uncovered 800 car park, a 250 seat lecture hall and the engineering plantrooms. Level 2 will include the A & E ward, neonatal ward, labour and delivery rooms and blood bank. A paediatric ward, three surgical wards and a small medical ward will be housed on level three. The top level will include two 56 bed medical wards and two 56 bed O & E wards. |
