The majority of the outstanding work involved will have to be carried out on Sundays as they are main traffic routes. Dublin City Council has plans in place to complete these projects but is however experiencing difficulty in getting them finished for the following reasons:
· Lack of staff due to the embargo on employment
· The difficulty of getting the staff that are available to work every Sunday
· The retirement of some key staff
· The pressure of completing other projects
· The fact that Dublin City Council has to find funding for these projects when it did not expect to have to fund them
Much of the lost time in completing the projects, to date, arose because Dublin City Council was pursuing the contractors involved in the various developments to deliver on their commitment. Unfortunately Dublin City Council now has to accept that these contractors are no longer in a position to deliver the works required and the City Council is left to deal with the problems. Dublin City Council will work on completing these projects this year but realistically some of the projects are unlikely to be completed until next year.
Please see below for information on the individual public lighting schemes you have queried:
The Historic Paving Stones are currently in storage and will be re-laid within the coming weeks as work at ground level is almost complete. Works to be completed by end September 2012
For various reasons it has been difficult to close off this project.
At Trinity College Dublin Science Gallery Dublin City Council went in to install the columns on the into town side after the civil contractor had completed his works. Unfortunately Dublin City Council could only install two of the four columns (these are the two columns with no lanterns on them) because some of the ducts that were to have been installed by the contractor could not be found and the electrical supply was not provided. Efforts were made to contact the contractor without success. Temporary lighting was installed on the far side of the street to maintain a good lighting level on the street.
At some of the junctions along Pearse Street some existing columns still have to be removed. These were not removed at the time due to electrical supplies inside the columns being used by other utilities such as cameras, bollards, traffic light controllers, telemetry meter cabinets and so on.
East of the junction with Macken Street on the out of town side again (called Gallery Quay) Dublin City Council was unable to complete works because of missing or damaged ducts. Here an additional pole had to be installed to get an overhead supply to the 4 no. new lights along here. The contractor who carried out the ducting works, Pierse Contracting has since gone into liquidation.
Work originally began in Ringsend as part of a rejuvenation project including redesigning pavement layout and the provision of a complete new lighting installation. The responsibility for developing the plan was given to consultant architects and the contract was awarded to a contractor. These improvements were being funded by the DDDA.
The Contractors were responsible for installing the foundation bases, ducts, cable chambers as well as installing the new lighting system. The lighting columns chosen for Ringsend were rejected by the residents meaning the lighting installation could not proceed. Dublin City Council’s Lighting Division inherited several issues from the Contractor (including sourcing of suitable columns manufactured to fit the foundation bases already provided by the contractor).
A concerted effort was made in 2007 to complete the scheme. However, significant problems were encountered. These included: missing foundation bases, loose foundation bolts, misaligned bolts, several foundation bases missing bolts, damaged ducts and cables.
A Civil Contractor was working on correcting these issues with approximately €50,000 spent on correcting the workmanship of the Contractor. Unfortunately due to missing or damaged ducting and foundation bases Dublin City Council have only managed to complete 60% of the project.
The lamp standards referred to in your e-mail are the inner steel cores of the replica columns. The outer embellishments which are an identical replica of the original lamp standards will be fitted by mid August 2012.
Historic Street Lighting - A Model for Dublin
A successful retrofitting of historic street lights with energy-efficient LEDs has been recently undertaken in the centre of the German city of Leipzig. The innovative project was spearheaded by Braun Lighting Solutions of Berlin and solid-state lighting experts Future Lighting Solutions, with the aim of renovating and making more efficient the host of historic Schinkel gas lamps that have been a feature of the historic city centre of Leipzig since the nineteenth century.
The challenge for the project engineers was to incorporate energy efficient LEDs into the historic lamps in a manner that replicated the appearance of the original clusters of gas mantles inside each lantern head, as well as maintaining the ambient warm glow of gas light that is a defining characteristic of the city centre after nightfall. The initial models for Braun’s trial were the last three original gas lamps in front of the famous St. Thomas Church, the home of Johann Sebastian Bach.
“In Leipzig, the LED technology of the future meets the past of city lights which are more than 150 years old,” said Andre Braun, CEO of Braun Lighting Solutions. “Our approach keeps the traditional form of the lamps but lets them shine in a new light through advanced LED technology. We have been able to deliver on the goals for energy efficiency and environmental protection at the same time as meeting the requirement to preserve a historical artefact.”
By equipping the 360 Schinkel lights around St. Thomas Church with the latest LUXEON® Rebel LEDs, the city can save €20,000 a year in energy costs. The LED lamps consume only 22W, by comparison with the 85W power consumption of the lamps they replace. This 73.3% reduction in the power load also reduces CO2 emissions by 60.8 tonnes per year. Thus, the project is an important contribution to the implementation of urban climate protection goals in Germany.
To achieve the effect of gas lighting, the original parts of the historic lamps were supplemented with a patent-pending technology that mimics the size and arrangement of the previous mantles. The four mantles were replaced by four LED modules covered by satined glass, giving the impression of glowing mantles suspended within the lamps. The difference between the LED lamps and the gas light originals can only be detected on close inspection. An elegant touch was the incorporation of a single 1.2W LED in the roof of each lamp to provide a subtle glow for the opal glass at the top of the unit. Future Lighting Solutions also managed the process of ensuring consistency in colour temperature across all of the hundreds of LEDS used in the sceheme.
A Model for Dublin?
The Trust believes this is the type of project that Dublin should be undertaking as part of its Draft Public Realm Strategy in partnership with the Lighting Department of Dublin City Council. There is a number of locations where such as world-class synergy of heritage conservation and cutting-edge technology should be utilised, including, for example, the re-erection of the original 84 historic oil lamps that once graced the railings of Mountjoy Square, through to reinstating the private lamps of many of the city’s Georgian streets, as has been successfully undertaken in Edinburgh. Dublin's quays could also benefit from such unified treatment, as well as many of its smaller streets and lanes.
The Trust has also advocated the retention of the traditional pillar standards on Grafton Street as part of its proposed repaving plan, and retrofitting them with correctly designed, high quality historic Dublin lantern heads fitted with sparkling LEDs.
In spite of the widespread use of silver Scotch Standard lampposts on the city's streets - many reproduction - extraordinarily, there are almost no enclaves of historic lighting left anywhere in Dublin. Recent attempts to replace lantern heads on St. Stephen’s Green and the Ha’penny Bridge have resulted in poor, factory-produced imitations that in no way accord with Georgian oil and Victorian gas lighting in the city, while historic lighting even outside public buildings leaves a lot to be desired. There is a sore need for a reassessment of Dublin city centre’s lighting needs and how the city can best present itself through informed lighting design as part of a high quality public realm. One option could be to undertake a short study of historic Dublin lamp types, and incorporate these into the palette of materials currently being composed by Dublin City Council as part of its upcoming Public Realm Strategy.
