Defra Network eTendering Portal - Hertfordshire Chalk Groundwater Model Phase 2
Status: Awarded
Published Date: 25/10/2022
Closing Date: 13/05/2022
Value: neg.
Hertfordshire Chalk Groundwater Model Phase 2 - The Hertfordshire Chalk Groundwater Model (HCGM) represents 4060km2 of the Chalk aquifer to the north-east of London, including the county of Hertfordshire, parts of Buckinghamshire, Bedfordshire, Oxfordshire, Essex, Cambridgeshire, and London. The model represents a number of Chalk streams that are situated in the Wye, Colne and Lee catchments. These catchments have been previously assessed to suffer from large scale over abstraction through the Catchment Abstraction Management Strategy (CAMS) methodology. The EA is looking to procure an external contractor to deliver Phase 2 of the project, which will deliver the Formulation of Revised Conceptual Model. This phase will refresh the existing foundation conceptual models and merge them into a single conceptual model that will then be updated. This will then support proposals for further development of the model in Phase 3. The objectives of Phase 2 are: 1. To refresh the existing foundation conceptual models and merge them into a single conceptual model 2. To gather and review necessary datasets and literature to support merged conceptual model update, reporting on initial model conceptual model uncertainty and data gaps 3. To expand the conceptual model where new data and literature is available for several concepts such as influence of superficial deposits, karstic development, evidence of hydrogeological layering within the Chalk 4. To report on the updated conceptual model and make recommendations for development and refinement of numerical model in MODFLOW 6 (Phase 3)

National Nuclear Laboratory - Integrated Energy Systems Modelling Collaboration Centre
Status: Closed
Published Date: 24/10/2022
Closing Date: 21/11/2022
Value: neg.
Integrated Energy Systems Modelling Collaboration Centre - NNL has directly commissioned energy systems analysis projects previously. In establishing a Collaboration Centre however, we aim to leverage NNL's investment of £1 million to deliver a total value of over £5 million by drawing in contributions from - and aligning activities with - other non-nuclear organisations and initiatives. This directly aligns with the strategic intent set out in the NNL Strategic Plan through the Clean Energy Focus Area (CEFA) and the Science and Technology (S&T) Agenda for development of Collaboration Centres that harness the resource and capability from a range of organisations and leverage funding and knowledge for greater overall impact on achieving decarbonisation and net zero by 2050. The IESCC will build on and complement existing UK initiatives and capabilities. As such, the Supplier must be able to demonstrate access to a credible integrated energy system modelling capability for the duration of the five-year programme.

Defra Network eTendering Portal - North East Area Magnesian Limestone Conceptual Model and Source Protection Zone Updates
Status: Closed
Published Date: 19/08/2022
Closing Date: 21/09/2022
Value: neg.
North East Area Magnesian Limestone Conceptual Model and Source Protection Zone Updates - We are looking for one contractor to complete work for the following two, overlapping projects: 1. NE Area Magnesian Limestone Conceptual Model (MLCM) Report update The MLCM report was originally produced by ESI Ltd consultants in 2009 and comprises of a main document, numerous appendices and a number of GIS shapefiles. The report focuses on the Permian Magnesian Limestone aquifer located in the Environment Agency's North East (NE) Area. The aquifer extends from South Shields in the North to Hartlepool in east and Darlington in the west. Since 2019 much work has been carried out by the Agency and partners, with improved knowledge of the aquifer gained therefore an updated conceptual model is required in order to consolidate and synthesise this updated understanding. Work to update the document commenced in 2020 however there was insufficient resource to complete the work in house therefore only a few sections were updated, focussing mainly on the hydrology of the aquifer and water company abstractions. Further work is required to complete an update to the conceptual model, consolidating and summarising recent understanding and ensuring all sections of the report are up to date. 2. NE Area Groundwater Source Projection Zones (SPZs) update Groundwater Source Protection Zones (SPZs) are areas of groundwater where there is a particular sensitivity to pollution risks due to the closeness of a drinking water source and how the groundwater flows. They are used to protect abstractions used for public water supply and other forms of distribution to the public such as mineral and bottled water plants, breweries and food production plants. Existing SPZs are designated across the Magnesian Limestone, Fell Sandstone and Millstone Grit/Coal Measures (Morpeth) aquifers within with the EA's NE Area. The majority of the existing SPZs were hand drawn in the 1990s, with only the Morpeth zones being completed at a later date in 2005. The conceptual understanding of the areas aquifers has changed and improved vastly over the past 20-30 years and the water environment is very different. As such, the existing zones may be significantly out of date and need reviewing and updating, where necessary. The EA is looking to procure an external contractor to deliver the work required to review and update both the MLCM report and all SPZs within NE Area. The outputs of the work will aid internal EA staff carry out various regulatory functions and help internal and external understanding of North East aquifers. The objectives of the work are: - To review, update and finalise the Magnesian Limestone Conceptual Model Report for North East Area - bringing the existing conceptual model up to date with current and updated data, literature and understanding. - To review and amend and create new groundwater Source Protection Zones for potable supplies in North East Area, across all aquifers.

Defra Network eTendering Portal - NEA - EcoSF3 - Lot 4 - North Tees Nature Site Project
Status: Awarded
Published Date: 04/08/2022
Closing Date: 23/05/2022
Value: £128,000
NEA - EcoSF3 - Lot 4 - North Tees Nature Site Project - The North Tees Nature Park (NTNP) Project is centred on the restoration of intertidal habitat on the Tees estuary edge, and is part of the Tees Tidelands Programme. The Project will look to assess the potential to lower land to create a terrace of intertidal habitat where currently there is a steep bank of waste slag. The Project will allow the natural migration of intertidal habitat as sea levels rise and help address some of the impacts of climate change.

Solihull MBC (SOL) - SOL - Dorridge Park Watercourse
Status: Closed
Published Date: 23/05/2022
Closing Date: 20/06/2022
Value: £45,000
SOL - Dorridge Park Watercourse - The main task in this assignment is to complete a flood modelling exercise on an unnamed watercourse and the associated mill race in Darley Green to understand the best methods of flood mitigation to local properties, as well as the potential ecology improvements that could accompany the flood mitigation methods. The mill race begins at the weir in Dorridge Park, flows through the mill pool and through a culvert under Darley Green Road, before re-joining the natural watercourse further downstream near the culvert under the railway. The task should include the following: o Walkover Survey o Topographical Survey o Development of a 1D-2D hydraulic model o Optioneering Assessment o Economics Appraisal Peak velocities, flood maps and hazard from the fluvial model should be presented in an appropriate format. If necessary, a conference call should be organised by the contractor to discuss the implication of the new fluvial flood extents.
