Valencia: Nou Mestalla roof lift underway toward 2027/28.

Valencia CF said on 4 September that Nou Mestalla had begun the “Big Lift” of the main roof structure — radial cables, hangers, and struts raised to the compression ring in one of the project’s most complex engineering phases, with work continuing over the following weeks, the club reported. Soft recorded without choosing: the club roof-progress note is dated 4 September (soft for an overnight Saturday strip); Scout first-pass preference flagged the item but folder origin does not waive the bar — facts were verified and the short runs with careful attribution. Capacity and schedule figures are not taken from the September club roof note.

The club earlier reported completion of the compression ring and 50 steel pillars that will support the roof (Valencia CF, 8 June 2026). That June club note said the fifty S355 steel columns — each standing about 38 metres tall and weighing more than 30 tonnes — were installed under FCC Construcción supervision after transport from Horta Coslada’s facility in Arteixo, Galicia, and that radial cables supporting the roof were then being installed. The 4 September club page framed the Big Lift as the transition from provisional assembly at pitch level to the definitive roof configuration: upper and lower radial cables, ring elements, connectors, rigid and flexible hangers, and reinforcement components lifted with synchronised hydraulic jacks on the compression ring, then sequential hangers, structural struts, and final tensioning over the coming weeks. After the Big Lift, the club said, work continues with the secondary roof structure, technical walkways, arches, and outer membrane.

StadiumDB lists planned capacity at 70,044 and completion targeted for July 2027, ahead of the 2027/28 season, after work resumed in January 2025 under FCC (StadiumDB construction page; Valencia CF). Soft attribution lock: capacity 70,044 and the July 2027 / 2027–28 aim are StadiumDB (and prior project docs as StadiumDB/OneFootball frame them), not the September roof-lift club note — the short attributes roof progress to the club and capacity/schedule to StadiumDB. StadiumDB’s construction card also lists Fenwick Iribarren Architects as design and Fomento de Construcciones y Contratas with Grupo Bertolín as contractors, and frames the long pause from the unfinished 2007–09 build until the January 2025 restart toward a summer 2027 finish. A StadiumDB June news item on the completed compression ring likewise tied finishing work through summer 2027 and noted a readiness target framed around early July 2027 on that card — still StadiumDB schedule framing, not the 4 September club lift note.

Named actors and checkable milestones locked to published sources: Valencia CF (4 Sep Big Lift club note; 8 Jun compression ring and 50 pillars); StadiumDB (capacity 70,044; July 2027 / 2027–28; January 2025 restart under FCC). Soft FLAGs hold: Scout preference is a preference signal only, not auto-HOLD; the 4 September club date is soft for the overnight Saturday strip and is labeled as such; capacity and schedule stay on StadiumDB. The desk does not invent matchday move-in dates, sale of the old Mestalla, or league-approval outcomes beyond what those published pages state.

The checkable record is the club’s 4 September statement that the Big Lift of Nou Mestalla’s main roof structure is underway, the club’s 8 June report that the compression ring and 50 pillars were complete, and StadiumDB’s listed capacity of 70,044 with completion targeted for July 2027 ahead of 2027/28 after the January 2025 restart under FCC.

What comes next is checkable: further Valencia CF construction updates after the Big Lift phase; StadiumDB’s published capacity and schedule lines for Nou Mestalla; FCC and club notices on secondary roof structure, walkways, arches, and membrane as those pages are updated; published La Liga and club schedules for when Nou Mestalla is listed as the home venue.

Floor: Valencia CF 4 Sep — Nou Mestalla Big Lift roof underway (radial cables/hangers/struts to compression ring); club 8 Jun — compression ring + 50 pillars; StadiumDB — capacity 70,044 / July 2027 / 2027–28 after Jan 2025 restart under FCC; soft: Scout preference ≠ HOLD; 4 Sep date soft; capacity/schedule = StadiumDB not club roof note.
