Composite Metal Flooring : New Victoria Hospital
Victoria Hospital, one of two acute care hospitals in Fife, has been serving the Fife public since the early 1960’s. As part of NHS Fife’s overall strategy to modernise health services in the acute and community sectors, a major new wing at the south of the hospital is currently under construction.
The project will transform healthcare delivery in Fife, creating a first-class facility for patients and staff alike. The project itself involves the construction of a 50,000m2 new hospital wing, linked to the existing Victoria Hospital to the south of the current tower block.
Unlike the 1960’s Victoria Hospital buildings, dominated by a large rectangular tower block, the new wing has been designed as a waveform. In order to accommodate the undulating wave-like western façade of the new wing, the steelwork has been erected around a 7.0m x 8.1m grid.
To facilitate the build programme and ensure the finished structure adheres to the Scottish Government’s stringent Firecode SHTM 81 (Fire Precautions in New Hospitals) and SHTM 85 (Fire Precautions in Existing Hospitals), 50,000m2 of ComFlor® 51 shallow composite profile floor deck was specified for the construction of the six floors in the new wing.
Fraser Darrington, Sales Director, Severfield-Reeve Structures comments: “Key to the successful delivery of the project has been ensuring we meet the tight construction programme. The ComFlor® 51 composite floor deck is ideally suited to fast track projects as the system is manufactured in factory-controlled conditions.
Benefitting from long spans that require minimal mesh reinforcement, the composite system enables the concrete to be laid quickly after the composite decking installation – allowing the floor installation to be completed within the tight construction timescales.” ComFlor® 51 is a robust, made to measure shallow, dovetail re-entrant composite floor deck that can be installed quickly and efficiently – ultimately bringing significant time and cost savings to the construction programme.
The profile comprises of a mechanical key that is positioned in the concrete slab which is strengthened by cross stiffeners located in the profile trough. These combined properties provide strong shear bond performance and excellent structural performance – essential when constructing a facility that will see thousands of people pass through its doors every day. Coupled with its structural performance, ComFlor® 51 presents a virtually flat soffit and a relatively thin slab, enabling it to meet stringent fire design requirements. Alongside this, the dovetail re-entrant properties of the composite floor deck result in very small openings in the deck itself, which help to prevent the transfer of heat through the slab in the event of a fire.
Robin Hamill, Project Manager, Fisher Engineering comments: “Fire safety is of paramount importance when designing a hospital and the ComFlor® 51 composite profile system lends itself perfectly to such a project by virtue of its fire performance credentials. The fire performance of the composite beam is excellent and even for two hours fire rating, the top flange of the steel beam does not require fire protection, when specified with the ComFlor® 51 composite deck. This provides us with the confidence that we can construct a facility that will not only stand the test of time, but will perform to the strictest fire safety standards.”
Roddy Mackay, Project Director, Balfour Beatty Construction comments: “An important consideration for the Victoria Hospital was the issue of fire safety. The specification of ComFlor® 51 profiles provides us with the confidence that the finished structure will meet the demanding NHS Scotland Firecode fire safety regulations and give 100% resistance in the unlikely event of a fire.”
Roddy continues: “Working in close proximity to the existing hospital posed us a challenge as a large amount of the early works took place only a few feet away from the working hospital.
Therefore, it was imperative that the materials we specifed were able to keep noise and overall disruption to the
hospital to an absolute minimum.”
The specification of ComFlor® composite floor decking has facilitated a rapid build programme and ensured tight construction timeframes will be met, whilst focusing on and adhering to important fire safety regulations that NHS facilities dictate. The finished building will provide a highly secure, fire resistant and structurally robust building that will continue to serve the communities in and around Fife for the next hundred years.
The new wing at Victoria Hospital will open to the public in early 2012.
