PROJECT DESCRIPTION

The Crescent Building was constructed in three phases and comprised a seven story structure, containing 232 apartments with 9 cores and a considerable ground floor podium slab over parking. Mick Foran was the Contracts Manager for this project and won the prestigious “Construction Manager of the Year” award for his successful delivery of the project. The overall scheme comprised 450 residential units with retail space at podium level and had a value of €80m.

CHALLENGES FACED
- The contract was awarded as a RIAI Blue Form without quantities. It was a fixed price contract and cost control was of utmost importance to the client.
- The programme was tight, requiring delivery of the project within 22 months and left no scope for contingency.
- Careful consideration was given to production management and quality control ensuring that the building was watertight at an early stage.
- The complexity of the design meant there was considerable potential for buildability problems. Intensive forward planning was necessary to avoid potential risks in identified areas.
- The curved shape of the building presented a challenge in terms of cutting and fitting the steel roof beams to match the contours of the structure.
- The overall setting out on the building had to be very precise to ensure all pre-cast techrete panels fitted exactly once they arrived on site.
- Most challenging was the installation of the punch-out window areas. Projecting approximately one metre from the face of the already-fitted techrete panels, these cantilevered areas comprised a concrete / stone and insulation sandwich panel with a further steel frame over the base, carrying limestone face work and window infills between the stone pilasters. This required considerable on and off-site coordination with subcontractors.

TECHNOLOGIES
- The complex design consisted of 5 arcs for setting out with a faceted slab edge.
- Wide spans, large faceted techrete panels, significant window systems, boxed out steel balconies and steel backed stone clad projections on the top two floors added to the complexity of the project.

SUCCESSES
- The attention to detail and quality of the project exceeded the client’s expectations, which reduced snag lists and facilitated the early closing of the units.
- The project was completed one month ahead of programme and within budget. The final account was agreed 3 months before the end of the project, which reflected the tight control of costs.
- There were no accidents during the 21 months of construction.
- The successful completion of Crescent Building led to the negotiation of Academy Building and Concert Building on the same site. These projects had a combined approximate value of €45m.
