The Bangor Drainage Area Plan (DAP) project involves the design, construction and commissioning of improvement works at major combined sewer overflows (CSOs) and wastewater pumping stations (WwPSs) within the Bangor area of Northern Ireland. The first phase of the proposed infrastructure improvements involved upgrade work at Luke’s Point Wastewater Pumping Station to help alleviate pollution spills, particularly during periods of heavy rainfall.
NI Water (Client), AECOM (Designers) and BSG Engineering (Designers/Contractors) worked closely together to deliver a high profile scheme which showed close working, excellent communication, and many environmental/social considerations.
The project scored 97% for Project Management in its CEEQUAL Assessment and this was a driving force behind the project’s ultimate success.
The good communication and project planning of the project could be seen in the Project Initiation Plan in 2012. This document set the scene for the upgrade work at Luke’s Point as well as the other proposed upgrade works within the Bangor area. This document, combined with the Works Information by the client NI Water, showed from the outset that a clear plan was being developed for the project which allowed progress to be driven by clear and knowledgeable decision makers.
An Integrated Project Team Organogram made clear the structure of the project team and this gave important clarity of responsibilities between and within the different team members.
In addition, all members of the project team adopted a whole life approach to the project from an early stage. A Capital Works Programme and Carbon Calculator were initiated for the project and this was an important driver for the project’s environmental and social considerations which were originally set out in the Works Programme and the original tender documentation.
Sustainable environmental and social performance
The client regarded past environmental and social considerations as an important part of the tender submission process. The commitment to sustainability from project inception was shown by a signed charter by the contractor and the organogram by the rest of the project team.
For the client and designers, the main environmental risk of the project was from unacceptable intermittent discharges to Belfast Lough and associated flood risks from the pumping station. This was identified early in the project and shown in the Project Risk Register, which was evaluated and prioritised according to significance.
The Site Waste Environmental Management Plan (SWEMP) took into consideration these factors and gave a detailed document of environmental and social compliance. The CEEQUAL assessment was able to draw heavily on the SWEMP in order to evaluate how mechanisms of sustainability were put in place and ultimately measured against objectives as set out in the Works Information. These mechanisms were implemented and monitored through sustainability reports, regular waste returns, and site progress reports.
Value engineering and sustainability excellence
As part of the scheme, construction methods and materials were considered with environmental and social factors in mind. This was most clearly shown in two documents: ‘Opportunities for Energy Reduction’ and the ‘Value Engineering Report’. The latter document evidenced reused materials, best available techniques for construction, and the refinement of the outline design – all project management actions which allowed sustainability to thrive on the project. The ‘Opportunities for Energy Reduction’ showed how the contractor was considering sustainable materials, limiting material export, and using local supplies to ensure maximum use from every piece of timber, rock and screw. As well as this, the Delineation Map produced by the contractor showed how the reuse of materials on site was planned and project managed from an early stage of the project.
One of the main innovative techniques used to monitor environmental performance on the scheme was the flood alarm put in place by the project team to ensure the upgraded pumping station met the targets set by Department of Agriculture, Environment and Rural Affairs (DAERA). The monitoring system works by triggering a high level alarm as effluent spills through the screen and into the overflow chamber. This high level spill alarm flags up and logs both on site and on NIW’s telemetry system. This system now ensures pollution events from the upgraded wastewater treatment works are closely monitored and reported promptly to all concerned.
Communicative & collaborative team work
One further aspect of the project which stands out is the training on social and environmental performance. Key members of the project team all participated in toolbox talks at the start of the scheme. This was crucial as it allowed an increased awareness of water pollution, energy reduction and good neighbourhood/stakeholder relations as the scheme progressed.
