Summary of the contracting process

Perth & Kinross Council is buying road pavement coring and Dynamic Cone Penetrometer (DCP) testing for use by Perth & Kinross, Dundee City and Angus councils. The work will assess the structural condition of roads and inform cost-effective carriageway resurfacing design. Coring will establish pavement layer thicknesses, reveal material condition and the depth of cracking, and identify samples for hazardous-material testing. DCP testing will assess the unbound pavement layers and their California Bearing Ratio. The work also includes traffic management, testing cores for tar-bound layers, and laboratory analysis where required to assess coal-tar-related hazards. Sites are identified by the councils, with additional cores potentially required at a site. Work is carried out across the three council areas.

The councils invited offers through an open procedure. The tender deadline was 30 November 2026 at 12:00 UTC, and the evaluation period was scheduled to begin at that time. The contract period runs from 26 February 2027 to 23 February 2029, with two possible 12-month extensions. The estimated contract value is £400,000. The procurement is arranged as one lot. Evaluation considers technical capability, financial standing and suitability. Bidders must provide two examples of comparable work from the previous five years, financial information for the previous two financial years, and confirm their insurance arrangements. Technical requirements cover the specified coring, DCP, sample preparation and hazardous-material testing standards. Community benefits are included. Bids must remain valid for 90 days; variants are not permitted.

This requirement suits road investigation and pavement-testing contractors able to combine site coring, DCP testing, laboratory sample preparation and assessment of potentially hazardous road materials. The testing company and laboratory must have UKAS accreditation for the relevant work, including core assessment and logging, DCP testing, sample preparation, PAH screening and benzo(a)pyrene hazard assessment. Required methods reference DMRB, BS and ADEPT guidance; certain tasks allow approved documented in-house methods or equivalent recognised procedures. Suppliers need to manage traffic safely in accordance with Chapter 8 and the applicable street-works code. Bidders must demonstrate comparable delivery experience and suitable financial standing and insurance. Quality, health and safety, and environmental management credentials are required, with documented management procedures accepted as alternatives to specified certifications. Subcontracting intentions must be stated.»}

Notice Information

Notice Title

PKC14212 - Cores and Dynamic Cone Penetrometer Testing

Notice Description

The primary objective of this contract is to identify a suitably experienced and qualified contractor to gather information on the structural condition of the road network. This information will be used by Perth and Kinross Council, Dundee City Council and Angus Council to design cost effective carriageway resurfacing projects. To aid the design of the road maintenance projects, coring is required for investigating structural condition.

Lot Information

Lot 1

The cores will provide important information about layer thicknesses and provide an opportunity to examine the visual condition of the various materials in the pavement. We require cores to be taken through various deformations such as cracks to provide a means of determining the depth of cracking, which has serious implications for the maintenance of the road. They will also identify areas of good, bad, and intermediate condition. Coring also provides information on hazardous materials that can be subjected to further testing in the laboratory, where appropriate. Once the road has been opened, Dynamic Cone Penetrometer (DCP) tests can be carried out to reveal further information about the condition of the unbound layers with the CBR value. The testing organisation shall provide a core at 50 metre alternating lane intervals and DCP tests in accordance with CS 229 at sites identified. The testing company/laboratory to be UKAS accredited for data assessment core/core logging/DCP to DMRB CS 229. Additional cores may be required at each site which will be identified by the appropriate Council representative prior to commencing the tests. The supplier will be required to provide traffic management in accordance with Chapter 8 of the Traffic Signs Manual/Safety at Street Works and Road Works: Code of practice to carry out the cores and DCP tests. Each core sample is to be tested for the presence of tar bound layers, as detailed in the guidance note 'Managing Reclaimed Asphalt Highways and Pavements' ADEPT 2024 and further guidance prepared by Scottish Road Research Board 'Dealing with Coal Tar Bound Arisings' 2018. If a core sample contains the PAHs characteristics of coal tar following the PAK marker spray test, then on instruction by the delegated Engineer's representative, further laboratory testing may be required to carry out PAH analysis for benzo(a)pyrene content to determine if the planned excavated material is Hazardous or no Hazardous with PAH analysis and is to be classified in as per the list of waste code from 'Guidance on the classification and assessment of waste- WM3' SEPA as detailed in the guidance note 'Managing Reclaimed Asphalt Highways and Pavements' ADEPT 2024. The testing company/laboratory must have UKAS (United Kingdom Accreditation Service) accredited, to ensure confidence in the results. The purpose of the testing is to identify the excavated waste material as hazardous/non-hazardous material as detailed in the guidance note 'Managing Reclaimed Asphalt Highways and Pavements' ADEPT 2024 in appendix C/D.. To ensure that testing is adequately controlled in the laboratory, the sample preparation and testing laboratory must be UKAS (United Kingdom Accreditation Service) accredited. Full details are available in tender document PKC14212 Evaluation Guidance.

Renewal: The contract has 2 extension options of 12 months at a time.
