In November 2010 RPA Metro North Roadshow hit Dublin City Centre. The Roadshow was made up of four presentations on Metro North in the city centre focusing on O’Connell St, Westmoreland St, St Stephen’s Green and Parnell Square. The presentations show how the city centre is going to look like during Metro North construction.

Simply the enabling works are works carried out prior to the main contract and consist of diverting existing services out of the way of the main construction works as well as heritage works and tree removal And the main works are the construction of the stations themselves, but more of this later in the presentation.
There are examples of Metros where both Client and Contractors have got this wrong and lost site of the ultimate aim. Where the needs of the businesses have not been recognized and the works executed without careful planning and consultation. A quick trawl of the internet will bring up examples like Vancouver and Dusseldorf to name just 2. This has led to businesses suffering losses and even closing due to the construction works. There are also examples where this type of construction has been carried out , taking into account local business and delivering significant benefits to the area post construction, from personal experience Borough High Street Station on the Jubilee Line Extension carried out in the mid 1990,s is a good example and bears many similarities to the O’ Connell Bridge area. Work was carried out in a recession, construction of the box and ticket hall were almost identical to O’Connell street and we did’nt lose from memeory any business along the way. The area is now thriving. This is the outcome we wish for Metro North . We want all of you to be here when the line opens and reap the benefit that Metro will bring as part of a world class transport system that will allow Dublin to develop over the next century.
Pedestrian access – life blood of many shops & businesses in O’Connell Street and keeping access with Good Quality Walkways that are well maintained is essential. Access for servicing and deliveries is absolutely key to businesses functioning – reminder that there is a new delivery survey in the information packs, update from 2007, it helps us to understand your business and aids us in the planning of the works so if I could ask all of to fill theses in when you have a chance and send them back in the pre paid envelope, thank you. Access to car parks Getting the message across – all the good work is undone if we do not get this message over and the perception is that Dublin is closed
Noise- no real explanation need here , we are in a very sensitive Urban environment and our work methods have to reflect this. Limits have been set as part of the planning condition and we have to stay within theses and aim tobe better than them Hoarding - Cara will give a presentation following this one Lighting - so that a safe environment is created and customers will still pass by the shops fronts. House keeping – yes we have work to do during the construction but keeping the worksite tidy, removing excavated material as soon as possible once dug, keeping the plant serviced and clean To work in a city city center we have to set the highest possible standards if we wish to have a successful outcome.
Read the Slide Enabling works As mentioned earlier the EW£ works are the works that need to be carried out to facilitate the main works. Duration 18 months
Daniel O’Connell by John Henry Foley in 1882 William Smith O’Brien by Thomas Farrell and moved to O’Connell Street 1929 Sir John Gray by Thomas Farrell and erected in 1879 Jim Larkin by Oisín Kelly an unveiled 1979
Statues to Collins Barrack plinths will be stored else where.
Trees removed but replace with similar size specimines at end of the works
Orientation Utility Diversions are required to clear the area of the Stop Box of utilities (gas, electricity, drainage, telecommunications) to allow the uninterrupted construction of the main works, and includes - Local Diversions ,Sub station relocations and Service Tunnels Works have been designed and phased to provide - Access into buildings, Access across O’Connell Street, Continuity of supply, Access for deliveries and servicing of business, & Maintaining existing traffic arrangements
Oriention Looking at both O’Connell and Westmoreland Streets we can see the extent of the Enabling works and that if we carried out these works in one go then we would effectively close the City RPA have developed a design and methodology to achieve the Aim of not materially affecting business. This includes the phasing of the works and carrying out the works in small bites. I am going to quickly run through the next 16 slides to illustrate this approach. Yellow indicates worksites during the day and blue is work carried out “out of hours”and I will explain this in more detail later in the presentation. Before I run through the phases it is worth noting that for simplicity some of the worksites have been grouped together and will be sub divided and My colleagues in the Enabling works team who are here will be happy to discuss the details of access to individual properties after the presentation. Pedestrian access to businesses will be maintained during opening hours at all times. Most Phases are approximately 1 months duration
Install new manhole and drain in the median opposite the GPO Move northbound traffic lanes on to the median between Abbey St and the GPO Build Manhole at Abbey Street Install ESB and Eircom cables outside Clarkes and Easons
Connect drains from median Install ESB ducts Install Eircom ducts Divert Gas main
Install Luas Multi tubular ducting and chambers Drainage connections and manhole Water diversions Gas Diversion Eircom and ESB tie-ins
Divert southbound traffic onto median Complete Eircom and ESB connections OCS East Remove traffic off the median. Erect hoarding and commence excavation works for the Substation.
Potentially the impactful of the works is the construction of the utility tunnels due to their proximity to the buildings Looking at the buildings on either side of lower O'Connell Street we have a diverse range of businesses including banks, food outlets, retail outlets and educational & communication facilities. All of which have their own specific issues that need to be accommodated. For example Banks have specific security issues and access to cash points , safes etc outside of business hours. Food outlets require 24hour access for its customers
