Phase 2 Wards/Theatre/A&E Extension – Our Lady of Lourdes, Drogheda
GemElliott Construction Ltd has been appointed as main contractor to successfully deliver Phase 2 of Our Lady of Lourdes, Drogheda (OLOL2).
The existing hospital is a live acute hospital in the North East with an emphasis on Orthopaedics. The old part of the hospital was constructed in 1957 and Phase 1 of the recon- struction was completed in 2006. Phase 2 will consist of A&E at ground floor level, Ward beds at level 2,3 &4 and level 5 will be operating theatres. All plant is at roof level both in doors and out door.
The project was awarded in February 2016 after restricted public procurement process. Prior to commencement we agreed a schedule of interface works with the Hospital and these works did not start until each method statement went through a strict approval process. Extensive enabling works had to take place prior to any construction works. This included installing a 6 storey dust screen in front of the hospital as part of the aspergillus prevention measures. Temporary retaining works were carried out to existing services and a di- version of Foul, ESB, medical gases and coms had to be undertaken before any foundations started. Toilets on the ground floor of the existing A&E department had to be relocated as part of the enabling works. We also installed 1 hour fire rated partition at each level to protect the existing hospital from dust and fire at each tie location.
Once the enabling works were completed we commence with the excavation works. The made ground was removed off site and the In situ concrete frame commenced. The frame was predominantly flat slab construction and we ensured that pre pour check sheet were in place for each pour. A two week look ahead was agreed for inspection notifications with the Design which worked very well.
At the start of the project the M&E contracts were awarded and we decided as a team to carry out the services coordination in BIM LOD350. The design and the plant and equipment was approved through a technical submittal process, managed by our M&E Manager Cathal Smith. Necessary delivery dates for plant and equipment was the key driver for the Submittal process and these were issued in good time to allow the de- sign team to review same. Coordination meetings were held every week and every other week with the de- sign team to ensure that the design was being achieved on site and that issues were being resolved quickly. Workshops were held with the design team and the hospital end users to ensure that systems met their criteria but also the project budget.
Once our Facade and Windows specialist contractors were appointed we commenced the design and technical submittal process to ensure that the design and performance criteria (BER) was being achieved prior to works commencing on site. All materials used on the project under gone this submittal process to ensure that all performance criteria were achieved and that the correct DoP’s and CE certs were available to complete BCAR compliance. We had a full time person on site ensuring that the new BCAR regulations were being adhered to in terms of compliance. The project Manager ensured that the Quality Control sheets were being completed and all stakeholders of the project were invited to take part in the signing off of all elements of the build.
Once the RC frame was completed we commenced with the blockwork infill external wall panels. The entire facade of the building was made up from Argeton Terracotta rain screen and Schucco curtain walling. Once the blockwork was completed we commenced with the setting out of the brackets for the rain screen and the installation of the vapour membrane and insulation. The panel support rails were fitted in conjunction with the windows being installed. Once the windows were installed the Terracotta panels and flashing were fitted. Prior to the Terracotta panel being fitted a void closure process was under taken to prove compliance.
A structural steel bridge link was also constructed over the existing hospital and linked Phase two with Levels 6, 7 & 8 within the existing hospital. The link was then cladded in Structural Curtain walling. These works were very difficult from a health and safety point of view due to the height and the restricted location of the link. Extensive temporary works took place prior to the install of this link. The temporary works design and methodology of install was all agreed with the design team and the hospital prior to works commencing.
Once the building was substantially weathered, we commenced with the 1st fix install of all partition and M&E services. Prior to works commencing a full technical submittal was issued from Gypsum to the Design Team for approval. Partition types were rationalised to en- sure compliance with the fire cert and robustness requirements. A very strict void closure process was adhered to on site which involved the Partitions, Mechanical, Electrical and Main Contractor to sign off on each wall. The zone was then offered up to the Client and Design team for inspection. Once approved the walls and ceiling were then closed. All void closures formed part of the O&M safety file which was uploaded on to Zutec.
The door submittal was given considerable consideration on the project to ensure compliance. Each door set submission was issued with its own certificate of compliance. All frame on the project were steel frame with goal post supports which formed a very robust detail. A sample room was constructed in advance of the finishes in order to agree all details within the bedrooms. The A&E treatment bay area was also prioritised in order to create benchmarks early on in the project.
Once the internal finishes commenced on the project we brought in additional resources to ensure that quality control was to the highest possible standard. Weekly trade coordination meetings was a key factor in the successful delivery of this project. Fitted furniture and floor- ing details where all workshopped with the hospitals infection control team.
Once areas become completed we carried out snagging of same using Site works. These are tracked and areas are locked off.
A commissioning programme is developed will all stakeholders three months from completion. This is tracked on a weekly basis. Once all testing and commissioning is completed the Design Team in conjunction with the Estate team are asked to attend a verification of com- missioning review. Once this is completed, the end user will be invited to demonstrations and all of these will be documented.
The O&M manual is worked on months from completion and all of the technical submissions information is stored for use in the O&M. The format is agreed with the Design Team and our full time on site QHSE officer keeps the O&M up to date on a constant basis. BCAR certs are also requested from the Supply chain early in the process to ensure an early BCAR compliance. Where possible we issue an early 21 validation notification to enable the end user use of the building as quickly as possible.
This project is a fine example of our ability and expertise in executing an Acute Healthcare project in a live Acute Hospital Campus.
