Project Appreciation and Objectives
Traditional construction techniques are subject to risk due to the weather, involve mixing materials in difficult locations and can be wasteful. Existing standards are written around bespoke traditional construction and hence can be a barrier to the adoption of new technology.
Modular construction is used more often on the continent than the UK although products are starting to emerge in the UK sewerage sector. Claimed benefits include:
- Higher productivity;
- Lower overall installed cost and carbon emissions;
- Less construction risk from adverse weather conditions, reduced traffic management and potentially less Health and Safety risk, and;
- Higher quality control.
This project will identify which sewerage elements could benefit from modular construction and identify barriers to its introduction. This could include sewers, pumping stations, CSO's, tanks, packaged treatment plants, separators, etc.
The objectives of the project are to:
- Provide water company participants with the necessary information to fully understand the potential advantages, limitations and savings (both cost and time) of utilising modular construction.
- Identify the products and materials which are currently available for modular construction of sewerage elements.
- Identify barriers to introducing modular construction for sewerage elements and review opportunities to mitigate these.
Benefits to Clients
- Ability to mitigate barriers to introducing modular construction and realise the potential to minimise capital expenditure, carbon emissions and risk from informed implementation on those sewerage elements that could be undertaken more effectively by use of modular construction.
- Review sewerage elements that participants are currently using, or are planning to use, and what products/materials are available
- Identify the true cost benefits of modular construction
- Conduct site visits to audit performance of modular construction products and traditional construction techniques
- Identify where modular construction would provide early, and best opportunities
- Identify barriers to implementation and revisions to standards that will be required to introduce this technology.
A report reviewing opportunities for using modular construction for key elements of the sewerage system including comprehensive details on the potential advantages, limitations and (capital cost/carbon emission) savings, together mitigating actions to remove the barriers to its implementation.
