Following the repeated flooding in recent years, Kilgallen & Partners have been commissioned by Local Authorities to design flood alleviation schemes for several areas prone to flooding. These schemes have commonly been designed and implemented in close consultation with the Office of Public Works.
Kilgallen and Partners typically provides the following services during the design of flood alleviation schemes:
- Topographic and Hydrographic Surveys
- Preliminary Design
- Floodplain Mapping
- Consultation with Stakeholders
- Cost Benefit Analysis in accordance with OPW Requirements
- Preparation of Part 8 Drawings & Reports for Planning Approval
- Detailed Design of Scheme
- Procurement & Assessment of Tenders
