II.2.4) Description of the procurement
Modelling solutions and their auditing. (Auditing will be primarily sourced through Lot 2 and Lot 3, with Lot 1 being used as an overflow for auditing work)
Includes (but not limited to) the following studies:
— DAP – Drainage Area Planning – model suitability assessments, asset and flow survey planning, management of asset and flow surveys, working in close collaboration with the monitoring contractor, model build, model verification against short-term flow surveys, long term telemetry datasets and historic information, assessment of deficiencies, option modelling for both for individual solutions, and catchment wide interventions and model maintenance,
— DAP/UPM – as above, but with the inclusion of water quality modelling within the sewerage network. Build and calibrate river flow and quality models. Assess the impacts of Yorkshire Water assets on the receiving watercourses against UPM FIS and/or percentile standards. Run future scenarios to identify compliant solutions. Work collaboratively with monitoring contractor to provide sufficient data to support models,
— WFD (non-UPM water quality studies). Understanding of non-UPM environmental problem. Suggestions and implementation of river flow and water quality build and calibration. Sediment oxygen demand study. Work collaboratively with monitoring contractor to provide sufficient data to support models,
— DWMPs (Drainage and Wastewater Management Plans) – building on existing models to assess current, short, medium and long-term deficiencies and develop timely interventions at a strategic level to address identified deficiencies.
The model outputs will all be required to comply with the specifications defined in the contract as well as adhere to the market standards as defined by:
— UDG code of practice for the hydraulic modelling of urban drainage systems, UDG competency framework, UDG rainfall guide, WaPUG user notes, WaPUG integrated urban drainage modelling guide and WaPUG guide to quality modelling of sewer systems.
— WRc A guide to short term flow surveys of sewer systems,
— UPM manual, Version 3.1,
— YW’s Integrated Catchment Modelling (ICM) approach,
— relevant environment agency guidance.
There will also be a need for site surveys to be conducted which will include but is not limited to:
— manhole surveys,
— ancillary surveys,
— pumping station surveys and drop tests,
— connectivity surveys,
— contributing area surveys.
The supplier will also be required to procure and manage laboratory services for the analysis of water quality samples.
Where appropriate, the supplier will also be required to obtain land entry access and highway works permits all within a timely manner as well as the necessary YW access permits.
The principles of the Health and Safety CDM regulations must also be adhered to when executing these works, specifically to the design of sewer network, water quality and river flow surveys; the consultant will undertake the role of Principle Designer for these monitoring surveys.
