Hegarty Demolition was the contractor of choice when Spain Courtney Doyle needed an experienced and specialist team to undertake a €4m mixed development at Orwell Road, Rathgar. The development – which comprised a mix of basement car parking, retail and residential units – showcases the many diverse specialties that the company can bring to a wide range of contracts.

The comprehensive schedule of works included selective demolition, reduced level excavation, basement construction, general construction and the completion of all works to fit-out stage.

The site originally contained a two-storey period type retail outlet on one street frontage and a garage with filling station on the other. These buildings were demolished, while retaining the period façade, and all surrounding buildings were weathered and supported. A reduced level excavation and dig for a single storey basement and a variety of retention systems were implemented to suit several adjoining properties and roadways.

The basement structure required the installation of a system of 4.0m deep rotary bored piles to include Gewi high yield steel anchors as a rock anchoring for the structure.
The project involved the construction of a reinforced concrete structure to include external retaining walls to ground level, and core walls and partitions to roof level. The external walls are a pre-cast patented system designed, manufactured and shipped to site by the German company Betoform GmbH. The units were hoisted, erected and propped by Hegarty operatives under the guidance of the manufacturers.

Hegarty Demolition carried out all finishing works up to fit-out stage including roofing, mechanical & electrical installation, passenger lifts, hard landscaping and the reinstatement and making good to all adjoining properties. A feature of the works was the construction of a double A roof, finished with natural slates on timber trusses constructed from salvaged pitch pine timber all braced with a system of metal brackets and stays reflecting the original roof.

Hegarty Demolition carried out these works as the main contractor working in a very busy environment and surrounded by several adjoining owners to a very strict programme and without claim or complaint.

The works were completed without hitch and in complete harmony with the client’s in-house design team.
