Mapping and Modelling Framework · Defra Network eTendering Portal (Aug 2021)

A high-level scope of services is detailed below.

The framework will have a four year duration with an estimated value of £13m and will be available for use by other Risk Management Authorities.

Suppliers should note that mapping and modelling works related to planned construction projects for the EA are unlikely to be delivered via this framework, with these being delivered under the EA’s Collaborative Delivery Framework. This framework will focus more on flood and coastal erosion modelling, forecasting and flood hydrology improvements, and national/catchment scale modelling, mapping and forecasting projects not linked to the development and delivery of schemes that contribute to the target to reduce risk to 336,000 properties in the 6 year capital programme (noting that this approach is likely to differ for other RMA’s that may use the framework and which may therefore include pre-construction modelling).

FRAMEWORK STRUCTURE

The Agency’s intention is to appoint four/ five suppliers to a single national Lot, providing a centralised and consistent national approach to deliver all requirements. The Agency expects that the majority of work delivered under the framework will be appointed following mini-competition between all suppliers appointed.

It is intended that call-offs will use the NEC4 Professional Service Contract.

ADDITIONAL REQUIREMENTS

Effective emergency/ contingency support is critical for the successful delivery of the MMF and the EA is considering two options around this:

1: Suppliers provide a ‘best endeavours’ approach

2: Inclusion of a formal 24/7 standby system ahead of weather events and projected incidents. Additional information: The scope of services includes:

• Modelling (Fluvial, Tidal, Open Coast, Continuous Simulation, Overtopping, Surface Water, Groundwater, Sewer, Whole System, Weather)
• Wave transformation analysis
• Surge analysis
• Hydrology
• Model Peer Review
• NPPF Flood Risk Assessment Checking
• MDSF2
• Survey and Mapping Services
• Incident Management and Emergency Planning
