MA SUMMARY REPORT/Page 8 Preliminary Budget Based on the recommended scope of improvements, the conceptual construction cost and related project costs result in a preliminary budget of approximately $7 75 million, in current dollars, assuming that the work would be implemented as a single project The budget will need to be verified in the future once the work scope and schedule have been finalized $6,036,916 Conceptual Construction Cost $1,704,783 Related Protect Costs &Allowances $7,741,698 Preliminary Project Budget for a Single Project Project Phasing If the Town determines that a single project is not fiscally possible, then the work could be implemented in phases However, a phased project will be less efficient, will require deferral of certain aspects of the work, and will inevitably exceed the cost of a single project The approximate cost of phasing the Cary Memorial Building project, in current dollars, would be $9 4 million, an estimated increase of $1 68 million dollars, or 22% higher than the cost of a single project in current dollars The distribution of work items and approximated budgets for each phasing option are noted below PHASE 1 Accessibility&Auditorium (without HVAC improvements) $ 2,816,836 PHASE 2 Estabrook, Lobbies,Toilet Rooms& Stage Support Areas $ 1,766,509 PHASE 3 Other Meeting Rooms, HVAC Systems, Fire Protection $ 3,781,560 PHASE 4 Site Improvements (Ramp, Drop Off, HCAP Spaces) $ 548,777 Restoration & Repairs to Existing Fixed Seating in Auditorium $ 255,000 Replacement of Existing Acoustical Shell Array on Stage $ 250,000 PRELIMINARY BUDGET for PHASED PROJECTS $ 9,418,682 PRELIMINARY BUDGET for SINGLE PROJECT $ 7,741,698 APPROXIMATE COST INCREASE FOR PHASED IMPROVEMENTS $ 1,676,984 The Phases have been determined based on an understanding of the facility and of users' needs coupled with prioritization of elements that would provide the greatest level of perceived improvements in a sequential order For example, Phase 1 includes improvements to the Auditorium along with the provision of accessibility to the Bird Room, Civil Room and the Stage However, HVAC improvements would be deferred to Phase 3, still requiring the system to be turned off during acoustically sensitive events Similarly, renovations to the Green Room below the Stage would be deferred until Phase 2 Executing the project in phases would result in more extensive disruption to ongoing occupancy of the building due to the need for sequential, multiple projects Expectations of the public may be challenged through this series of projects the work scope will not address all concerns simultaneously Accessibility variances, which are not assured, would need to be obtained incrementally since not all of the building's various elements and spaces would be made fully accessible in any one phase Cary Memorial Building Evaluation Mills Whitaker Architects LLC June 2011 /Town of Lexington MA SUMMARY REPORT / Page 9 materials used, including the exhaust piping, brackets and associated fasteners, should be color galvanized or powder coated stainless steel to limit the possibility of future rusting so that the brick facade will not be damaged PRELIMINARY SCOPE & BUDGET PRELIMINARY SCOPE A preliminary project scope has been developed based on user comments, town needs and existing conditions of the facility This project scope is referred to as being "preliminary" because of the limits of this design study and the possibility that some project components may vary in scope between when the study is published and the time comes to implement these recommendations Each of the assumptions and observed conditions in this report should be reviewed and confirmed as part of the subsequent schematic design, design development and construction documentation process in anticipation of project implementation The project scope is verbally described below in several categories of work Illustrations of the proposed floor plan modifications that accompany these preliminary scope recommendations are detailed in Appendix A where the existing floor plans are shown followed by demolition drawings and preliminary plans indicating the proposed alterations Each of the floor plans (basement, first, second, attic, roof) and the site plan should be consulted while reviewing the recommended project scope as noted

their own staff, thereby eliminating the expense of retaining an OPM as a professional consultant The preliminary budget will need to be reviewed again in the future based upon a final project scope and the overall cost will need to be escalated when the schedule for project implementation has been determined A summary of the preliminary project costs is as follows $6,036,916 Conceptual Construction Cost $1,704,783 Related Protect Costs &Allowances $7,741,698 Preliminary Project Budget for Single Project A comprehensive summary of the cost components that comprise this preliminary budget is provided on the following page Refer also to Appendix E for a detailed breakdown of costs that were used in establishing the various construction values Cary Memorial Building Evaluation
