A recent development beside The O2 Arena at the Greenwich Peninsula in east London has seen a hotel with conference centre, plus prestige apartments. Life safety products from Gent by Honeywell have been specified.
The £121m building works included the construction of a new hotel, InterContinental – The O2 (pictured, ground floor), conference centre facilities and 100 serviced residential apartments named The Arora Tower, which offer views across Canary Wharf.
The hotel has been designed to BREEAM ‘Excellent’ standards and comprises 453 guest rooms, five food and beverage outlets, 19 meeting rooms, as well as a spa, pool and gym. The Arora Ballroom can accommodate 3,000 people. Measuring 80x39m, it’s not much smaller than a football pitch.
Liverpool-based NSI Gold installer HESIS was invited to tender for the life safety element of the project across the entire site. After its proposal was accepted it began working with building services specialist, HE Simm, during the early stages of the development. Barry Juggins, Managing Director of HESIS says: ‘One of the reasons we were successful in our bid was our ability to offer a proactive approach, which was seen as a huge positive, particularly in a scheme of this size. Just as importantly, as a Gent Technology Centre we knew that we could supply, design, install and commission the very best in class fire detection and alarm technology in the new buildings.’
Fitted were four fully networked Vigilon panels alongside Gent’s S-Quad devices. Martyn Keenan, Business Manager (North West & North Wales), at Gent, says: ‘S-Quad was the first intelligent loop powered multifunctional device to include a sensor, sounder, speech and EN54-23 certified visual alarm, and it has developed an enviable reputation for its ability to prevent unwanted alarms. Incorporating four separate sensing elements – heat, carbon monoxide, and dual angle optical forward and backward scatter, S-Quad combines local processing in the sensor and the panel to achieve an immediate response to genuine fires.’
The BS 5389 compliant category L1 solution deploys automatic detectors in all areas of the building – including roof spaces and voids – with the aim of providing early warning. The devices have been configured so that a visual alarm and a recorded voice message give occupants warnings in an emergency.
Barry Juggins says: ‘S-Quad devices with speech have been installed throughout the hotel and apartments, with a Comprio D1 public address and voice alarm (PA/VA) solution, which combines advanced audio management with a flexible architecture in a compact design. In addition, we opted for dual optical and heat detection in the bedrooms to avoid unnecessary unwanted alarms, due to the particular environmental conditions.’
With a combination of high ceilings and the need for minimum disruption during any maintenance, the conference centre and ballroom have FAAST aspirating smoke detection. Point detectors were not viable, while beam detectors, which can be installed at heights of up to 25m, were not considered practical. Aspirating smoke detection’s resilience, stability and high degree of sensitivity combines to reduce unwanted alarms. Furthermore, it offers a low total cost of ownership compared to traditional detection methods, it is claimed, which are more costly due to access equipment requirements, cleaning, replacement of devices and the labour required.
Installation was relatively straightforward, the installers report. Barry Juggins says: ‘The main challenge was the fact that the construction of the hotel, conference centre and apartments all ran concurrently and had to be completed at the same time. We ended up installing around 2,500 Gent devices across the three buildings, which met the customer’s exacting brief.’
Hasham Soliman, General Manager at InterContinental London – The O2, adds: ‘We now have a truly magnificent place for visitors to stay, for companies to host events and for residents to live. Part of this experience involves ensuring that people, property and assets are protected by the very best life safety technology, and thanks to HESIS and Gent by Honeywell, that’s exactly what we have.’
