The contract for the N19.6 billion project was awarded to an indigenous firm, Monier Construction Company, MCC, on June 8, 2024, following its approval by the State Executive Council.
Originally scheduled for completion within nine months, the project timeline was disrupted by the March 18 emergency rule imposed on oil-rich Rivers State by President Bola Ahmed Tinubu.
The two-storey complex, which accommodates the 32-member House representing 32 state constituencies, features 34 office spaces, elevators, galleries, meeting rooms and conference halls. 
The contract also covers the renovation and refurbishment of other existing structures within the complex, as well as provisions for an ambulance bay and other external works.
The Assembly complex was demolished after a section was reportedly bombed in a bid to thwart alleged impeachment plans against Governor Siminalayi Joseph Fubara by 27 lawmakers loyal to former governor Ezebunwo Nyesom Wike.
However, the state government dismissed claims of a bombing and attributed the demolition to structural defects resulting from explosions and fire outbreaks.
On Monday, Governor Fubara undertook an inspection tour of the Hallowed Chamber to assess progress. During the visit, the contractor reaffirmed its commitment to completing the project by December 2025.
Buoyed by the assurance, the governor expressed optimism that he would present the 2026 Appropriation Bill to lawmakers at the newly reconstructed chamber, rather than at the Assembly quarters where the Martyns Amaewhule-led legislature has been sitting for over 20 months.
Fubara, who was accompanied by Boniface Emerengwa, member representing Ikwerre/Emohua Federal Constituency, and the management of MCC Nigeria Ltd, said he was satisfied with the level of work and hopeful that the December 2025 deadline would be met.
He reiterated his commitment to ensuring the Assembly Complex is completed on schedule so lawmakers can resume sitting at the Hallowed Chamber. According to him, once that happens, he will present the 2026 budget there as required.
“We have been working hard to ensure their permanent sitting chamber is put in place. You know the drama that surrounded our relationship before, but by the grace of God, now that everything has been sorted out, it is our desire to ensure that the Assembly returns to their normal place of sitting,” he said.
Governor Fubara noted that although work had been ongoing before the emergency rule, there had been perceptions that nothing was being done.
“So I came here to ascertain the extent of work done, and I feel very impressed with what I have seen,” he said, adding that the contractor had already subcontracted the interior and some external works to Julius Berger Nigeria Plc to accelerate progress and meet the delivery timeline.
