COST ESTIMATE To provide a viable cost estimate for the bond measure, DLR Group provided a detailed narrative of a modern courthouse that itemized the type of construction details and methodologies, security measures, building systems, etc. This information provided a baseline of understanding to identify any areas that may require higher construction values than a typical office building. Additionally, DLR Group provided the design development drawings for a similar courthouse and government function building. These drawings provided current WA State energy code requirements, systems and zoning information, access patterns, building envelope requirements, and basic material information. The cost estimate is a conceptual level estimate based on overall project area, not a fully itemized estimate based on uniformat detail information specific to this project. However, the additional detail provided will allow a comprehensive understanding of what may be required. This estimate is also based on procurement of a GC/CM alternative delivery model common for courthouses. This methodology is different than the traditional design - bid - build methodology because it brings a contractor onto the project during design to act as a construction manager for the project. This assists in overall planning, evaluation of cost, and forward scheduling of the project. This is used for more complex projects such as courthouses. Though there are additional preliminary fees that are identified in the cost estimate, it is typically effective for cost protection throughout the project and ensures a capable contractor is procured for the project success. The cost estimate exclusions are provided at the bottom of the estimate and are important to consider in the planning of the bond measure. Because escalation rates are itemized based on starting the project in Quarter 2 of 2025 for construction, this can be factored should the project not be started at that time. 20 IODLRGROUP ESTIMATE OF PROBABLE PROJECT COST To complete a project, the County needs to account for more cost impacts than just the construction budget. These additional costs are considered "soft costs" and are typically proportionally based on the construction costs or "hard costs". This assessment provides a range of anticipated additional costs. It is not comprehensive of all costs associated with the project and they are provided on historical estimates not proposals or full review of costs required. It is common for the soft costs to add 30-40% more value than the hard costs and are consistent with this estimate provided.
