On Friday 2 October, the Spata–Artemida Municipal Committee approved the implementation study for the project ‘Completion of the Sports Centre at the Mazareko site’. It also authorised the Technical Services Department to instruct the contractor, CTESIBIUS TECHNIKI E.E., to commence construction works. Decision 615/2026 was passed unanimously, with one member abstaining, and was published on the ‘Diafania’ transparency portal on Monday 5 October.
According to the Technical Service’s recommendation, approval of the implementation plan was ‘the final prerequisite’ for the go-ahead to be given. Five months after the contract was signed, work on the Spata indoor sports hall can now begin. The item is the fourth on the agenda of the Municipal Council meeting on Tuesday 6 October, at 18:00.
€1.8 million, including design work by the contractor
The tender was announced on 14 October 2025 with a budget of 1,500,000 euros plus VAT. CTESIBIUS TECHNIKI E.E. offered an average discount of 3 per cent. In February, the Municipal Committee awarded the contract to the company (Decision 57/2026) for €1,455,600 plus VAT, i.e. €1,804,944 including tax. The bid from another tenderer had been rejected. The project is being carried out under a programme contract between the Municipality and the Region of Attica, which was signed on 30 December 2024. Its purpose, as described by the Municipal Council, is ‘the definitive upgrading and full operational restoration of the facility’.
The works contract was signed in April 2026 and entrusts the contractor itself with the final design and detailed design. The final design was submitted on 19 June and approved in August (Decision 523/2026). The implementation design was submitted on 20 July. On 14 September, the Building Authority updated the building permit with the details of the final design. The Technical Department concluded that the implementation plan was ‘fully in line’ with the permit, the contract and the specifications.
The dispute with the OAKA
In order for the contractor to gain access to the indoor arena, the Municipality first had to reclaim it from the OAKA. In September 2025, the sports hall had been granted free of charge to the Athens Olympic Sports Centre for one year. The handball and hockey federations trained and played there whilst work was being carried out at the OAKA.
Municipal Council Decision 132/2026 describes what happened next. The OAKA, claiming that it had spent 1,000,000 euros on improvements to the facility, requested to retain it until 30 December 2026. The Municipality refused. The project contract had been in force since April, and any further delay in handing over the site would expose it to an ‘immediate risk of work being suspended’ and to claims from the contractor. At a meeting on 7 September, the two sides agreed to suspend the concession with immediate effect. The 16 days remaining until its expiry, on 23 September, will be allocated to the OAKA once the project has been completed and licensed. The Council approved this at an emergency meeting on 16 September.
The OAKA has also requested a special protocol governing the entry of its staff in the event of an emergency whilst the suspension remains in force. In the text of the decision published on the ‘Diafania’ transparency portal, where the protocol should be described, the following note appears: ‘[THE EXACT CONTENT OF THE PROTOCOL IS TO BE FILLED IN]’.
What the documents do not yet reveal
None of the decisions specifies when the project is to be handed over or when the Spata clubs will be able to use the indoor facility. The deadline is set out in the contract published on the Central Electronic Register of Public Contracts (ADAM 26SYMV018898913). The next step is for the Technical Department to issue the go-ahead.
