Editor's note: This article has been updated to clarify a timeline for repairs and stadium use.  An opening date for the McKinney ISD stadium and community event center remains unknown as investigations continue about cracks in the concrete at the stadium, according to a presentation during a MISD meeting Tuesday night. Cracks at the approximately $70 million stadium are located in the home concourse, visitor concourse and home and visitor concourse lower bowl wall. These areas were brought to the attention of Manhattan Construction and Stantec in January. Nelson Forensics, an investigative and forensic engineering organization, completed a report about the home concourse and visitor concourse but is still looking at the home and visitor concourse lower bowl, MISD CFO Jason Bird said. MISD hired Nelson Forensics in April to review the three areas of concern. The completed report showed the home concourse was constructed improperly, which leads to long-term durability and maintenance issues but does not pose a life safety issue, Bird said. "Manhattan [Construction] and Stantec have agreed to remove and replace the home concourse," he said. "Timing and process of removal and replacement are to be determined." Nelson Forensics has given its analysis for the visitor concourse to MISD, but Manhattan and Stantec are now having their own experts review the analysis. Bird said he thinks the three entities will have a unified conclusion in July or early August. MISD will wait at least six more weeks for Nelson Forensics' report on the home and visitor concourse lower bowl, Bird said. Depending on how long investigations take and how long it takes to make necessary repairs, the stadium could be used for all, some or none of the 2018-19 football season and all, some or none of the 2018-19 soccer season, Bird said. However, since the concrete cracking is not a safety issue, the district could use the stadium for the upcoming school year and repair the stadium when the 2018-19 soccer season ends. Delaying the repairs could impact the 2019-20 football and soccer seasons, Bird said. "Obviously, before we would want Manhattan and Stantec to remove and replace the home concourse we want to make sure that every single thing is checked, rechecked and checked again to make sure that anything that could potentially lead to less than our high-quality, long-term durable, low maintenance concourse is corrected in that process," Bird said. "We do not want to remove and replace and find out later that we did not overturn the last possible stone that would cause us to end up in the same place we are today." Any financial costs associated with the three areas of concern will be resolved by the existing stadium budget or by Manhattan or Stantec, MISD board President Curtis Rippee said during the May meeting. While the investigation continues, work on other portions of the stadium and event center is expected to take place. All other work on the stadium should be complete by Aug. 1, Bird said. When complete, the stadium will feature 12,000 seats, 2,000 parking spaces and a community events center. Funding for the stadium comes from the $220 million 2016 bond program.
