Tender
Dundee opens a damp and rot framework to general contractors
By Staff Writer | 05-09-2026
Dundee City Council has tendered a multi supplier framework worth 5,200,000 pounds for rot survey and treatment, woodworm infestation and chemical mould removal in domestic properties. Tenders close at noon on 5 October 2026. The notice was published at 4:06pm on 4 September 2026 and runs through the Scottish public contracts portal under reference DCC/NS/55/25.
The council is seeking a minimum of three and a maximum of five contractors for each lot. There are three lots: surface treatments for condensation, dampness and mould excluding fogging; invasive treatments and investigation; and mould treatment fogging. Bidders may apply for all three. The notice also says each lot will be awarded to the highest scoring bidder. Both statements appear on the record and neither is reconciled by it.
The first lot is not reserved for specialists
The Contractor is not required to be a specialist timber-preservation company. Suitably competent general building or joinery contractors may tender, provided they can demonstrate the necessary competence, experience and resources to deliver the complete works in accordance with the specification.
Dundee City Council, tender notice, Lot 1
Where specialist treatment, surveying, electrical, plumbing, gas or other regulated work is needed on Lot 1, the contractor may use suitably competent and appropriately qualified employees or subcontractors. Treatment products, application methods, guarantees and supporting documentation all have to comply with the specification and be accepted by the contract administrator.
Lot 1 is open to any competent building or joinery firm. Lots 2 and 3 are not, and the qualification bar on them is membership of a named trade body.
The two specialist lots
Lot 2 is for specialist property preservation and invasive treatment contractors. Bidders must show specialist expertise in damp proofing, timber preservation, fungal decay treatment, wood boring insect eradication, basement waterproofing and associated remedial works. The principal contractor must be a current member of the Property Care Association and must keep that membership for the life of the framework. The contractor must employ suitably qualified surveyors and technicians and be able to provide surveys, specifications, treatment recommendations, insurance backed guarantees where applicable, and completion certification. Subcontracting of specialist preservation treatments is not permitted unless the contract administrator expressly approves it.
Lot 3 is reserved for specialist mould remediation and environmental treatment contractors. Bidders must show proven experience in diagnosing, treating and remediating mould contamination in domestic and public buildings, including ultra low volume fogging equipment, antimicrobial treatments, filtration systems and moisture assessment equipment. Membership of the same trade body is required, or of an equivalent industry body approved by the contract administrator, and must be maintained for the life of the framework. Operatives must be trained and competent for mould remediation, with evidence of training, health and safety procedures, risk assessments and method statements for fogging and biocidal treatments.
How it is scored
Price carries 60 per cent. The scored quality questions carry the remaining 40 per cent: delivery of contract and quality of service at 10 per cent, resourcing of requirements at 10 per cent, communication with stakeholders at 5 per cent, customer care and non contact at 5 per cent, continuous improvement covering post inspection and remedies at 5 per cent, community benefits at 3 per cent and fair work first at 2 per cent.
Alongside those, a run of requirements is marked pass or fail. They include compliance with the specification, the council's information security and safe use policy, a cyber security questionnaire, the Construction (Design and Management) Regulations 2015, duty of care and health and safety risk management, a site specific risk assessment and method statement, a sample report, and response time including a twenty four hour response.
Each lot runs for 720 days with two further periods of one year available. Variants are not allowed. Community benefits are a contract requirement, and the notice puts the number at fourteen outcomes for all contractors across the duration. A subcontract clause is included.
The notice does not publish the number of properties covered, the expected annual spend, the split of the 5,200,000 pound figure between the three lots, or how the fourteen community benefit outcomes are allocated. It gives no gross figure and no indicative call off volumes.
