IN Brief:
- The 28 October procurement entry names Firntec as supplier and lists £788,694 excluding VAT for Phase 2C intrusive structural surveys.
- The ProcurePublic Building Safety Consultancy Framework includes Firntec among its appointed suppliers and permits direct selection under stated conditions.
- The entry also marks its lot as cancelled, leaving final contract execution unverified despite its award classification.
Firntec is named as the supplier for a £788,694 Phase 2C intrusive structural survey package associated with Southampton City Council, extending the authority’s programme of investigating the condition of existing buildings.
The procurement entry, published on 28 October, identifies structural engineering consultancy services and gives an agreed price of £788,694 excluding VAT. It describes a direct selection through the ProcurePublic Building Safety Consultancy Framework, under which Firntec is an appointed consultant.
The final contract status is not fully resolved. Although the entry classifies the procurement as an award and names Firntec, it also marks its single lot as cancelled. The conflicting fields do not conclusively establish whether this particular call-off contract has been executed.
ProcurePublic’s framework runs from September 2024 to September 2028 and includes building safety assessment and structural engineering consultancy among its permitted services. Its published rules allow public bodies to select an appointed consultant directly in defined circumstances, including continuity with earlier work, similar assignments and urgency.
Firntec appears on the framework’s published list of appointed suppliers. The company has also undertaken earlier Southampton structural survey commissions, including a £360,000 Phase 2 contract concluded in December 2025 and a £650,000 Phase 2B contract concluded in March 2026.
Those earlier appointments establish a previous working relationship between the authority and the consultant, but they do not resolve the contradictory status information attached to the latest Phase 2C entry. The three values relate to separate procurement records and are not a combined award.
Southampton has identified structural investigation of its residential tower blocks as part of its building safety work. Earlier council procurement planning described high-rise buildings constructed in the 1960s, including large panel systems, as requiring investigation of their structural condition.
The council’s earlier programme contains several tranches of surveys. The Phase 2C entry does not identify the addresses, number of buildings or individual elements included in this particular package, so those previously listed blocks cannot safely be presented as its confirmed worksites.
Intrusive structural surveys provide information that cannot be obtained solely from a visual inspection. Engineers may need to expose concealed joints, examine reinforcement, recover concrete samples or test materials to establish the condition and load-bearing behaviour of an existing structure.
For reinforced concrete buildings, the cover protecting embedded steel reinforcement is an important part of the investigation. Its depth and condition influence the protection available to the steel, while moisture, chlorides and carbonation can affect the likelihood and progression of corrosion.
Carbonation reduces the alkalinity of concrete as carbon dioxide reacts with constituents in the material. Where the carbonation front reaches reinforcement and sufficient moisture is present, the protective conditions around the steel may deteriorate, allowing corrosion to develop.
Corroding reinforcement can expand and damage the surrounding concrete, resulting in cracking, delamination or spalling. Engineers must establish the extent of any deterioration and its relationship to structural capacity rather than treating the discovery of a local defect as proof of a whole-building failure.
Firntec’s investigation services include concrete core testing, measurements of reinforcement cover and checks for carbonation or chlorides. Samples can be examined in a laboratory, while scanning methods help establish the position of reinforcement before selected areas are opened for closer inspection.
The company’s wider capabilities also include assessments of large panel system buildings. These structures rely on connections between precast concrete wall and floor elements, with the condition and configuration of their joints influencing how loads are transferred through the building.
Investigations may involve opening selected areas to inspect ties or remedial brackets, checking the reinforcement arrangement and assessing concrete durability. The findings are then considered alongside structural calculations to determine whether existing connections and supports meet the required performance.
Such techniques form part of Firntec’s general technical offering; the Phase 2C procurement description does not specify which tests will be undertaken in Southampton. Its brief establishes intrusive structural surveys as the service sought without providing a detailed schedule of drilling, sampling or opening-up locations.
Survey work in occupied buildings requires the inspection programme to account for access to homes, protection of residents and reinstatement of finishes. Opening structural elements may require temporary restrictions while materials are examined and the affected areas are made safe after testing.
Investigations also need to distinguish between original construction details and later alterations. Historical drawings may omit subsequent repairs or strengthening, while testing can establish whether critical connections and material properties correspond with the assumptions used in structural assessments.
The resulting engineering reports can identify the construction encountered, the tests carried out, the condition of critical elements and any remaining uncertainties. Where further action is justified, recommendations may cover additional investigation, inspection intervals or the design of remedial works.
An intrusive survey does not, by itself, demonstrate that a building is unsafe or that strengthening will be required. Findings must be interpreted in the context of the structure, its loads, the relevant standards and the quality and extent of the evidence collected.
The £788,694 Phase 2C entry concerns specialist investigations and consultancy, not the construction of remedial works. Any structural repairs would require a defined technical scope and separate delivery arrangements based on the condition established through investigation.
Firntec is therefore the named supplier for a clearly specified type of consultancy within an established, active framework. Confirmation of the latest call-off’s concluded status remains outstanding because the procurement entry contains both award information and a cancelled-lot designation.
