Client: Glenveagh Ltd.
DBFL provided civil and structural engineering services for this large scale residential development (LRD) at Ballymastone, Donabate, Co. Dublin.
The development consists of 1200 A-rated residential units, a creche, retail and community building, as well as associated site infrastructure works on a c. 32ha greenfield site.
The residential development at Ballymastone is being delivered on a phased basis, will deliver significant levels of private, social and affordable housing for North County Dublin, providing a mix of 3 and 4 bedroom houses, 3 bedroom duplexes and 1, 2 and 3 bedroom apartment units.
DBFL developed an overall surface water drainage strategy in consultation with SDCC. Surface water management for the development is designed to comply with the Greater Dublin Strategic Drainage Study (GDSDS) policies and guidelines and the requirements of South Dublin County Council and the governments recently published Nature-Based SUDS guidance policy document.
DBFL are also carrying out the main civil engineering and infrastructure design including the following elements: Foul and surface water drainage including pumping station; Sustainable Urban Drainage (SuDS) features;Water Supply; Pavement, road, and junction design; Flood Risk.
This project demonstrates DBFL’s ability to work in a multi-disciplinary team, successfully delivering a phased residential development, with extensive co-ordination with design team members and public bodies to overcome challenges and successfully assess and minimise risks through innovative design as the project progresses.
DBFL in collaboration with a number of design partners are providing innovative offsite solutions to the construction of the houses, duplexes and apartment block. Timber frame, LGS and precast concrete construction will all be used as part of the overall scheme.
A key goal for the project was ensuring that as-much of the existing material was re-used as possible. Soil stabilisation was used to improve ground conditions on site and was also used as a capping layer replacement under some roads, and also below a number of residential units foundations. This reduces the requirements to reduce spoil off site and, in turn, reduces the amount of trips by tippers on and off site.
Numerous SUDS features have been adopted throughout the scheme such as infiltration basins, rain gardens, bio-retention areas, swales, permeable paving and gullies discharging to tree pits which minimise surface water flows to the downstream network.
