The project involves works such as bridge deck waterproofing, concrete repairs, and carriageway resurfacing. The total contract value is £561,233.60 GBP. The procurement stage was an award, and the contract was signed on 24th April 2023. The project is in the works category with additional classifications including crash barriers, bridge construction, waterproofing work, and concrete repair work. This tender for the Dan-Y-Graig Underbridge Refurbishment project by the Caerphilly County Borough Council presents an opportunity for businesses in the construction industry, particularly those specialising in bridge works, waterproofing, and concrete repairs. The project involves complex infrastructure improvements with specific health and safety requirements, making it suitable for experienced contractors with expertise in similar projects. Suppliers interested in bidding must ensure compliance with the eligibility criteria, including holding relevant industry certifications such as Constructionline membership and Health & Safety Accreditation. ## Notice The work will involve replacing 2No asphaltic plug, bridge deck waterproofing, concrete repairs to end of the edge beams, jet washing and application of protective coating to the end face of beams above the piers including breakout of spalled and loose concrete from soffit of beam ends above abutments and piers and application of protective coating.Because of the process required to renew the asphaltic plug joints it is thought that the old sheet waterproofing system will be irreparably damaged during the works and so it is deemed necessary to replace the old waterproofing with an up to date polyurethane elastomer spray applied system which has a far longer life expectancy than the existing system.In order to ensure continuity of the waterproofing, the polyurethane elastomer spray applied system and new bridge joints must be fitted from parapet to parapet. This will require that the existing asphaltic surfacing is removed and the concrete verges and central reservation on the bridge deck are excavated so that waterproofing can be applied directly to the bridge deck. The existing safety fence between carriageways will need to be taken down and set aside for re-use. The verges and central reserve will be reinstated with concrete and the safety fence re-fitted. The Western verge has 4 ducts set into the concrete that is being removed. They will be checked and if empty can be removed. They will not be replaced at this time. The East verge contains a drain fitted beneath it this will be removed during excavation and not replaced. Kerb drainage will be installed with rodding access points.As the joints and waterproofing are replaced each carriageway will be resurfaced with Hot rolled asphalt. Road markings and reflective studs shall be renewed.In order to carry out the work safely it is anticipated that it will be necessary to install a contraflow system so that an entire carriageway width of the bridge deck can be treated in one hit. The contraflow shall then be alternated so that the opposite carriageway can then be treated.The contraflow system will require enabling works to amend the existing crossover point adjacent to the roundabout with the B4591 and install a new crossover point approximately 50m to the north of the proposed works at Dan-Y-Graig Overbridge.Removal of approximately 100 metres of safety fence will be required at each crossover point, set aside then refitted once the bridge work is complete.Following a Principal Inspection and Special Inspection of the structure in May 2021 and March 2022 respectively, it was apparent that the ends of numerous deck beams below the expansion joints have suffered from concrete spalling with exposed corroded reinforcements and prestressing strands. However, the space between the soffit of the beams and top of the supports is limited to undertake any significant concrete repairs. Therefore, the proposed concrete repairs are limited to removal of the existing spalled and loose concrete from ends of all the deck beams followed by jet washing of the end faces of the beams above the piers to remove debris and apply cementitious protective coating to the ends of the deck beams with exposed reinforcements and prestressing strands including concrete repairs to bottom corners of the edge beams above piers. Concrete repairs also required to the west face of the northern pier. ## Key Details | Field | Value | | --- | --- | | Publication source | Sell2Wales | | Latest notice | https://www.sell2wales.gov.wales/search/search_switch.aspx?ID=128419 | | Notice type | S2W Notice - Website Contract Award Notice | | Procurement type | Standard | | Procurement category | Works | | Procurement method | Open | | Procurement method details | Not specified | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 15 Sep 2023 | | Submission deadline | 7 Mar 2023 | | Future notice date | Not specified | | Award date | 24 Apr 2023 | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | £561,233 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Not specified | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Active | ## Buyer | Field | Value | | --- | --- | | Main buyer | CAERPHILLY COUNTY BOROUGH COUNCIL | | Locality | HENGOED | | Post town | Cardiff | | Postcode | CF82 7PG | | Country | Wales | | ITL 1 | TLL Wales | | ITL 2 | TLL5 South East Wales | | ITL 3 | TLL53 Gwent Valleys | | Local authority | Caerphilly | | Electoral ward | Ystrad Mynach | | Westminster constituency | Caerphilly | | Delivery location | Not specified | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 1 | | Supplier names | TARMAC TRADING | ## CPV Codes ### Divisions - 34 - Transport equipment and auxiliary products to transportation - 44 - Construction structures and materials; auxiliary products to construction (except electric apparatus) - 45 - Construction work ### Codes - 34928100 - Crash barriers - 44212100 - Bridge - 45221100 - Construction work for bridges - 45233223 - Carriageway resurfacing works - 45233251 - Resurfacing works - 45261420 - Waterproofing work - 45262330 - Concrete repair work ## Release History - 15 Sep 2023 at 15:42 - Award - S2W Notice - Website Contract Award Notice - https://www.sell2wales.gov.wales/search/search_switch.aspx?ID=128419 - 24 Jan 2023 at 15:59 - Tender - S2W Notice - Website Invitation to Tender Notice - https://www.sell2wales.gov.wales/search/search_switch.aspx?ID=128419 ## Notice URLs - http://www.caerphilly.gov.uk - http://www.tarmac.com - https://supplierlive.proactisp2p.com/Account/Login - https://www.caerphilly.gov.uk ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
