The ongoing dispute between Great Hall contractor and the Denver International Airport concerning the terminal renovation product could still be resolved through mediation, despite a temporary lapse in negotiations. Airport officials and the contractor continue to exchange insults publicly over the matter.

The Denver Post recently obtained several letters related to the dispute. The letters reportedly paint the relationship as tumultuous long before the public dispute began and makes many doubtful that the current issues related to cost overruns and delays will be resolved anytime soon.

The two parties have three choices for resolving the matter: They could continue to seek third-party support and resolve the matter through mediation. They could litigate the issues in court, giving up control of the outcome to a judge. Or they could terminate the contract and go their separate ways entirely, something that would leave the future of the project up in the air indefinitely.

In the letters, airport officials discussed safety issues and accused the contractor of contract breaches and other accusations. It also said the contractor was dismissive about its concerns. The letters contained multiple warnings about safety issues faced by workers and travelers in the busy terminal because of the work site conditions.

According to Great Hall, the airport is being overly dramatic and making “meritless, time consuming” claims. The company disputes the safety claims and calls the accusations a distraction from the cost of the project. It also states the airport has changed the design, materials, and other elements, and accused the project to go beyond its original scope.

Mediation between the two parties took place in June, but led to no resolution. No specific date is set for an upcoming mediation, but it is expected the two parties will give it another try before taking more drastic measures.
