Design Process
T
he design for the overall Cork Airport project was
a highly collaborative process between Jacobs Engineering and Rohcon Limited. The Main Ter-
minal Development was undertaken by Jacobs Engineering, with Burro Hapold commissioned as the specialist structural consultants for the Terminal roof, while Rohcon limited were responsible for various elements of the main and surrounding structures, including;
• Detailing of steelwork connections. • Specialist glazing and curtain walling design. • Specialist Passenger Boarding Bridges design • Specialist Escalator and Lift Installations • Design and details of secondary steelwork for retail units, doorframes, openings, etc.
• The Design and Building of the Multi Storey Car Park
• Non Load Bearing Blockwork Design.
• Specialist Baggage Handling Installation
• Elements of Mechanical and Electrical Installations
• Detailing of Steel to Steel and Steel to Timber connec-
• Multi discipline co-ordination of services

Construction & Programming
T
he construction of the Cork Airport project
involved the consideration of a great range of factors due to the sheer number of the elements
involved. All the constituent parts of the project had to be carefully planned in order to maintain a successful outcome in line with the schedule, while keeping in mind the quality and cost of the development, plus minimising disruption to the existing airport, the adjacent hotel and the business park. In order to achieve this end, the agreed timeline of the project had to be strictly adhered. Examples of items undertaken to make sure this happened, included establishing fortnightly progress meetings and the creation of a concrete batching plant onsite. The plant, produced 60,000 metres of concrete over the three years of the program, proved to be fundamental in achieving the correct level of service and quality, in order to meet the construction deadlines.

ROOF STRUCTURE
The roof structure, consists of structural steel four limbed ‘trees’ each weighing in excess of 11 tonnes. From the tree tops, 20 Nr double glulam beams span the building from landside to airside, strengthened and stiffened by Macalloy rod trusses. Above glulam beam level, is a structural steelwork framework of purlins providing support to the lightweight double span curved roof deck. The roof deck is lined internally with acoustic insulation and an architectural panel which follows the wave form of the roof structure.

MECHANICAL INSTALLATION
• 6,600m2 of granite flooring
A highly important factor for the operation of the Terminal building is the mechanical installation process, and therefore of great concern during the construction process. The circulation of air throughout the building is provided by eighteen air handling units, with the fresh air intake located in the upper levels on the road side of the Terminal, avoiding exhausts which may be emitted from the airfield. The terminal contains a state of the art sprinkler systems, as well as two smoke evacuation systems for high risk fire areas and two gas suppression systems for the main electrical rooms. The uniting factor of the mechanical and electrical systems is the BMS (Building Management System), a system based on Direct Digital Control technology, monitoring all of the systems present within the terminal. It also serves to maximise the fuel and energy efficiency of the facility.

Site Works EXTERNAL SITE WORKS
With the restructuring of Cork Airport, vastly increasing the size and scope beyond the pre-existing structures, there was a resulting increase in the demands on the surrounding infrastructure. These expansions included the following:• A new landscaped dual carriageway entrance road to the Main Terminal Building and the existing Business Park. The dual carriageway includes roundabouts, footpaths, cycleways, lighting, signage etc, along with modifications to the roads leading on and off the route. • New short term, long term, staff and VIP car parking. • A reworking of the underground foul and surface drainage systems, as well as a network of underground power and communications ducts. • The development of new taxi rank, coach parking and car hire areas. • Extensions and redevelopments of the existing airfield, with provisions for increases of equipment storage and other facilities to handle the projected increase in aircraft traffic. • Various ground retaining structures and a pedestrian underpass.
27
The installation of over three kilometers of fencing along the airside was a very necessary step in order to outline and ensure the security of the site area. The excavation of over 500,000 cubic metres of material, a large quantity of it being rock, posed a significant worry that disruptions would be caused during its transportation, however with proper co-ordination and satisfactory health and safety measures, these worries were more than adequately addressed.

Bam Building Company Profile 33
A Brief History Ascon has its roots in the construction of the Wexford Bridge, which spans 400 metres across the River Slaney, at Wexford Town. A joint venture between HBG of the Netherlands and Sisk constructed this bridge between 1956 and 1959. Arising out of the successful completion of the bridge, the joint venture formed Ascon (short for Associated Contractors) to undertake civil engineering projects, primarily in Ireland.

HBG became to sole owner of Ascon in 1989. The building company Rohan Construction Ltd was acquired by Ascon in 1993 to be its building arm; it was re-branded as Rohcon. Ascon Contractors, the holding company for Ascon and Rohcon, and is Ireland’s second largest contractor and through Ascon is Ireland’s largest civil engineering contractor. Royal BAM Group of the Netherlands acquired HBG in 2003. BAM is ranked in the Top 10 of European construction companies.
