This initiative falls under the survey vessels industry category and is located in Mansfield, England. Currently in the planning stage, this tender has outlined an engagement deadline of 23 March 2018, during which interested suppliers are invited to express their interest in attending a meeting to discuss the requirements and provide suggestions for the future tender process. This tender presents a significant opportunity for businesses specialising in surveying services, particularly those with experience in environmental consultancy and water body assessments. Suppliers with capabilities in using advanced measurement techniques and remote-controlled surveying equipment will be well-suited to compete. The Coal Authority aims to optimise the measurement of ochre levels, and participants can potentially shape the tender specifications through their insights during the upcoming engagement, which could lead to contract opportunities that enhance business growth in the relevant sectors. ## Notice We operate 47 sites where mine water is pumped to a treatment scheme before being returned to a water course. Raw mine water is generally acidic and in some cases it is chemically dosed. The main contaminant in raw mine water is dissolved iron. The dissolved iron forms an iron oxide known as ochre that precipitates on exposure to atmospheric oxygen. Ochre builds up in the settlement ponds & reed beds. The Coal Authority removes the ochre on a periodic basis. The measurement of ochre in settlement ponds is required for the following reasons: * For The Coal Authority to establish the quantity of ochre * To optimise the removal of ochre from settlement ponds The Coal Authority has explored methods to undertake surveys using remote- controlled boats with sonar technology. This has highlighted that the cost of survey equipment is dependent upon the skill level of the operatives. For example, professional surveyors are likely to use a range of methods for verification of their results whereas site operatives can require a single method of measurement. The Coal Authority is considering outsourcing this activity to a third party that has transferable experience in surveying sediment in water bodies. Ochre levels are likely to require some manual intervention because there may not be a defined transition between the ochre and water phases. We are exploring options to inform a possible future tender to gather information on measurement techniques that could be utilized for this activity along with methods for data presentation. The tender may include provision for the measurement of ochre levels as follows: * On a one-off basis to determine ochre quantity at a particular site * For a full programme of annual measurements at each site We are aiming to deliver an optimal outcome in terms of accurate ochre measurement. We have not yet decided upon what the model for delivery should be for this requirement. We would like to invite interested suppliers to meet with us at our Mansfield office during March / April 2018 to better understand our requirements and offer suggestions on how we might fulfil our objectives through a future tender process. Suppliers are invited to provide contact details for this to be arranged. If you are interested in attending this event or are unable to and would like information sent to you please express your interest by contacting us at peterkobryn@coal.gov.uk no later than midday Friday 23 March 2018. We reserve the right to use any information shared within this market engagement to develop a mature service specification for future procurement purposes. Any costs incurred by participating in this exercise must be borne by the participating organisations. Following this exercise we shall determine if & how we will approach the market to secure the services. Please note that any procurement will be subject to a separate advertisement. ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/12f83096-c315-4d97-a137-65e2c6d77e6f | | Notice type | Market Engagement Notice | | Procurement type | Standard | | Procurement category | Not specified | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 1 Mar 2018 | | Submission deadline | Not specified | | Future notice date | 23 Mar 2018 | | Award date | Not specified | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planning | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | THE COAL AUTHORITY | | Locality | MANSFIELD | | Post town | Nottingham | | Postcode | NG18 4RG | | Country | England | | ITL 1 | TLF East Midlands (England) | | ITL 2 | TLF1 Derbyshire and Nottinghamshire | | ITL 3 | TLF15 North Nottinghamshire | | Local authority | Mansfield | | Electoral ward | Berry Hill | | Westminster constituency | Mansfield | | Delivery location | Not specified | ## CPV Codes ### Divisions - 34 - Transport equipment and auxiliary products to transportation - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 34513550 - Survey vessels - 90713000 - Environmental issues consultancy services ## Release History - 1 Mar 2018 at 13:39 - Planning - Market Engagement Notice - https://www.contractsfinder.service.gov.uk/Notice/12f83096-c315-4d97-a137-65e2c6d77e6f ## Documents - https://www.contractsfinder.service.gov.uk/Notice/12f83096-c315-4d97-a137-65e2c6d77e6f 1st March 2018 - Early engagement notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/7d95ecf5-c6bd-484b-8988-2620cde7fc4c Notice ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
