NATIONAL CENTRE FOR HEREDITARY COAGULATION DISORDERS (NCHCD), ST JAMES’ HOSPITAL
Clancy were awarded the contract for a 660m2 extension to the existing Central Pathology Laboratory in St. James Hospital, in preparation of the construction to the new Children’s Hospital.
The development consisted of the removal of an existing modular building located along the northern elevation of the existing Central Pathology Laboratory building which is situated in the north eastern corner of the hospital site. The new building will provide laboratory and office accommodation at ground floor and offices and staff facilities at first floor together with all associated temporary works required to facilitate the development.
The building was supported from a steel frame and was finished in a single ply roof finish, colour coated metal louvres, solid exterior facade panels which echo the adjacent mortuary and a brick plinth which matches the masonry to the existing building.
Construction was originally planned to commence on the 18th of January 2016 with a construction duration of 37 weeks and a handover date on the 21st of October 2016 and value of €2.2 million.
WHY THIS PROJECT WAS EXCEPTIONAL
Although this was not a large scale project, the complexity of the development was. The construction of the project was complicated by the existing underground services in the hospital grounds such as high voltage cables and steam pipes which required many investigatory digs and ground scans to establish exact locations and minimize the possibility of damaging these services while pile driving foundations, which could have led to parts of the hospital being shut down.
Traffic management was extremely difficult due to the location and restricted nature of the site together with the high volume of general traffic passing through the middle of the works. Another major difficulty was the location of the LUAS line which ran only meters from the site.
Any delays to the LUAS line had penalties of €1000 per minute so forward planning of deliveries and tasks were paramount to ensure no disruption to daily activities to both St. James’s Hospital especially Blue Light Routes and LUAS commuters.
To add further complications, the Central Pathology Laboratory was operational 24/7 and was to remain so for the duration of the works. Also, the projects start date was delayed due to design team issues, with a start date of 09-02-16 further shortening the construction programme.
USE OF TECHNOLOGY AND DESIGN
Clancy used BIM processes and models to design the building. This technology and models were used to help grasp the consultants design intent and allowed for Clash Detection of the complex services, Clancy organised with their internal BIM Coordinator to give training to all staff involved on the project so they could leverage technology such as Glue on mobile devices and Revit on desktops.
It was also a first project where we used robotic total stations that could bring in a BIM/3D model ensuring a finer quality control from setting out right through to finishes. Clancy’s were the first in the country to procure this type of trimble total stations and we wanted to ensure that its functionality was fully used to deliver this project.
As a result of engaging in this technology Clancy and the site management team were able to complete this project ahead of time with a duration of 32 weeks with a hand over date on the 03-10-16 within budget and to an extremely high quality finish.
