Truman Sports Complex Facility Assessments | Burns & McDonnell2I. Purpose and ScopeA. PurposeThe Kansas City Chiefs organization has a lease with the Jackson County Sports Complex Authority(JCSCA) that requires the organization to maintain Arrowhead stadium to a level consistent with aFirst Class NFL Football Stadium. The purpose of this study is to report the overall condition ofArrowhead Stadium and its immediate environs to determine if the team is upholding their leaseagreement.B. ScopeBurns & McDonnell, in conjunction with the JCSCA, has developed a Facility Assessment Report thatreviews and documents the stadium condition. During 2013 the JCSCA created a database thatdocumented the existing condition of all areas of the stadium. Burns & McDonnell received thedatabase, interviewed Kansas City Chiefs staff and reviewed maintenance records. This report isbased on the above review in conjunction with on‐site evaluations by Burns & McDonnell engineersand architects.Burns & McDonnell’s scope is limited in nature and does not include an entire facility room‐byroominspection or evaluation. An on‐site walk through of the stadium and its immediate environswas performed by Burns & McDonnell’s engineers and architects to spot‐check rooms and areas toensure that the overall conditions reported in the Jackson County Sports Complex Authority’scondition reports align with the actual conditions as observed. Additionally, Burns & McDonnellhas provided recommendations for observed maintenance issues that may need to be rectified inthe near future.
3 Arrowhead Stadium Assessment | 2014II. Executive SummaryA. General DescriptionArrowhead Stadium, located at One Arrowhead Drive in Kansas City, Missouri, is intended toenhance the fan game day experience, increase revenue generation, and improve the day to dayoperations of the Kansas City Chiefs and its other users. The stadium holds approximately 80,000fans and offers amenities such as club level suites, luxury suites, bars, restaurants, and othervenues geared towards large scale entertainment.B. General ConditionIn general, Arrowhead Stadium and its immediate environs appear to be in exceptional condition.It is apparent that the Kansas City Chiefs have performed the ordinary cleaning and maintenanceobligations consistent with a First Class NFL Football Stadium.Minor physical deficiencies were observed throughout various locations within The NewArrowhead Stadium and its immediate environs. Such deficiencies are expected in a such a largefacility and typical of a high‐use facility. These can be easily addressed by the Kansas City Chiefsthrough standard maintenance procedures.C. RecommendationsThere are no major items that require a recommendation to resolve. Section III – Description andCondition includes recommendations for the deficiencies observed for each building or sitecategory. These deficiencies are generally minor and may require attention in the near future. Asummary of recommendations may be found in Section IV (pages 21‐22).

The scope of the report is limited toonly a fraction of the equipment installed onthe site, ie. not all systems, equipment,plumbing fixtures, etc. were observed. Due tothe nature of the scope plumbing fixture shopdrawings, submittals and system testingcommissioning (Cx) reports were notreviewed as part of this report.The plumbing systems within the buildingappear to have been renovated “ as needed”with the latest updates performed in thespring of 2012. The majority of the plumbingsystems observed appear to be in very goodor like new condition. There were no majorissues and everything observed appeared tobe compliant with local code. The followingis a review of the plumbing systems and anycurrent deficiencies within the building.Plumbing Images:Exhibit D1.1Exhibit D1.2Observation/Comments: Various water heaters throughout the facilityappear to have corrosion at the base of theexterior shell.
