2 Lecture Details Construction of the Corrib Onshore Pipeline Ciarán Butler Chartered Engineer at RPS Group Ciarán Butler BE (Mech) MEngSc CEng MIEI - Technical Director, RPS consulting Engineers Ciarán Butler worked on the Corrib Onshore Pipeline from 2007 to 2015 as RPS Project Manager. He was responsible for managing RPS s delivery on the project through the route selection, planning and detailed design stages. The Corrib Field Development was discovered in First Gas happened in January, This presentation shows some of the many design and construction challenges that were met in order to deliver the Corrib Onshore Pipeline project safely. This included construction of the pipeline in sensitive peatland areas and the construction of a large temporary tunnelling compound adjacent to Sruwaddacon Bay from where the 4.6km segment lined tunnel was built. The presentation also shows how large infrastructure projects can be designed and built with minimal impact on the local environment. Corrib Onshore Pipeline Figure 1

5 Lecture Details Claridges Hotel 5 Storey Iceberg Basement Michelle Mackey Project Engineer at McGee Group Michelle is a civil engineer who has chosen a site based career over that of the design office. She has spent the past 13 years in the employment of specialist London based contractor McGee Group. During her tenure here she has worked on several notable projects including King Cross Station redevelopment, The Scalpel and AELTCC (Wimbledon Tennis Courts), and is currently Project Engineer for McGee on their design and build contract to construct a 5 storey basement below the world renowned 5 star Claridges Hotel in London s Mayfair, whilst ensuring the hotel remains fully operational throughout the works. Claridges hotel is a Victorian red brick building with a 1920 s art deco steel frame extension. The proposed basement is to extend across the entire footprint of the 1920 s extension, approximately 1250m 2, which is founded on a reinforced concrete raft slab, one of the first buildings to use this type of construction. The client s brief was to provide an additional 5 storeys below ground without closing the hotel for a single day as part of a 5 year plan to enhance the hotel. The proposal put forward by McGee s uses a number of techniques that, whilst have all been used before individually, they had not been used on a large scale in combination and more significantly, in a live building. With the support of Arup consulting engineers to realise McGee s conceptual design, the excavation of the basement is currently in progress by way of a series of temporary support tunnels and 26m deep shafts at each of the 61 existing column locations, all of which have been hand dug as the logistical limitations meant that mechanical methods were not suitable. This presentation will detail the challenges and innovative methods used to deliver the project.

8 Lecture Details Courthouse Refurbishments Package 1 & Package 2 John Bailey Chartered Engineer BA BAI, Dip Project Management, MSc MBA CEng FIEI Malone O Regan Consulting Engineers John is a Chartered Engineer and Project Manager with over 30 years delivering Industrial, Commercial, Building, Civil Engineering, Transportation and Infrastructure projects. His main interests are the Technical and managerial leadership of Engineering projects; Mullingar Courthouse is one of 7 Courts, delivered through a PPP process. Five of these buildings have conservation aspects; the most significant conservation works were in Mullingar courthouse. Waterford and Wexford also had conservation aspects. Existing Mullingar courthouse dated from The original fabric and features were largely intact but feeling its age (delamination of external walls, no bonding of wall junctions, settlement, damp, timber decay, vegetation, etc). Previous interventions included a concrete document store at first floor, a new floor over family court, new ceilings over courts, possibly the main feature stair, possible remodelling of the main court room. The proposed remodelling included new offices and custody areas built around three sides of the original building, remodelling and refurbishing the existing building, additional plant space, offices and meeting rooms at second floor / roof level, and at basement level. Two major intrusions into the original building were planned, public and reception areas at east side and reorientation and extension of court room at south elevation. The structural elements were to have a 75 year design life. Courthouse Refurbishments Figure 1
