Malahide Portmarnock Educate Together Secondary School

Project Details:

ABM’s role in the project was as Main Contractor and Project Supervisor for the Construction Stage (PSCS).

The building frame was constructed using precast concrete wall panels and hollowcore concrete floor slabs topped with concrete screed on pile foundations. The foundation solution incorporated reinforced concrete ground beams/ pile caps which are a durable robust system used to take concentrated loads from the superstructure and spread them evenly onto piles for transfer to the underlying clay stratum. Some structural steel was incorporated into the concrete frame design and installation to facilitate cantilevered slab areas & staircase landings.

The prefabricated wall panels and hollowcore slabs were delivered on an as-needed basis. The concrete frame was erected in two halves. The buildings external wall was made up of 90mm insulation fitted tight to the outer face of the precast wall panel, 60mm air cavity two and brickwork and rendered blockwork. The wall tie system for the outer leaf was the Ancon brick tie channel type, with vertical channels fitted through the insulation with compression sleeves, and then Ancon wall ties connected into the channels at the appropriate centres to restrain the outer leaf brickwork.

The roof construction comprised a series of pitched roof surfaces with Bauder membrane & standing seams on insulation on roof deck fitted to a structural steel frame. The top level precast roof walls were cast with notches to allow the sheeting rails to cross over the internal walls. Without such notches, the rails would have been fixed to the tops of the walls, thereby increasing the height to the top of the roof ridge, and creating a greater area internally for airtightness, fireproofing and acoustic works to be completed. Rooflights opes were trimmed out as necessary to provide for rooflights installation in areas where additional daylighting was required to be provided to satisfy requirements.

Mechanical and Electrical containment was surface mounted to the underside of the hollowcore slabs and to the precast wall panels. These works commenced once the 1st floor slab installation and screeding was completed.

Swords Community College, Co. Dublin

Project Description:

ABM’s role in the project was as Main Contractor and Project Supervisor for the Construction Stage (PSCS).
Precast concrete construction of 3 storey school on strip foundations.
Structural screed on precast hollowcore slabs.
Standing seam composite roof on structural steel frame.
The building frame was constructed using precast concrete wall panels and hollowcore concrete floor slabs topped with concrete screed.
Some structural steel was incorporated into the concrete frame design and installation to facilitate cantilevered slab areas, balconies and the roof terrace construction where it was necessary to achieve level thresholds at doors.
Off site techniques used for the school building included panalised metal frame external wall panels insulated off site and delivered to site in addition to precast hollow core slabs, so as to fit within the hot rolled steel frame.
Risk to the programme is reduced through off-site manufacture. Increased on-site installation speed of the internal walls and floors in conjunction with one and other results in the Mechanical and Electrical services works commencing earlier than when using the steel frame construction.
Using a complete precast structure has now become a popular choice for many construction projects throughout Ireland.
Precast concrete combines the benefits of rapid construction and high quality materials with the advantages of factory controlled production lines and quality assurance.
Temporary accommodation was established initially adjacent to new schools site. Appropriate segregation of site and school was necessary.

Grace Park Educate Together National School, Drumcondra, Dublin 9.

Project Description:

ABM’s role in the project was as Main Contractor and Project Supervisor for the Construction Stage (PSCS).
Precast concrete construction of 3 storey school on strip foundations. Structural screed on precast hollowcore slabs.
Kingspan Kingzip roof installed on structural steel frame.
The school elevations were clad in stone cladding, and had steep pitched roofs, so as to fit in with the existing adjacent buildings located within the grounds of the All Hallows Campus in DCU.
Temporary accommodation was established initially adjacent to new school site. Appropriate segregation of site and school was necessary.
It was also necessary to relocate some existing temporary accommodation on site as this encroached on the footprint of the new ETNS.
The school was constructed within the live third level DCU All Hallows education campus.
There was therefore significant traffic management required to segregate construction works from those accessing the existing college.
Restrictions of deliveries were put in place at college drop off and collection times.
Construction staff parking and site access routes were arranged so as to ensure no disruption to the existing campus during the works.
