  2. • 1969: Building completed. 2 occupied floors with support spaces and storage in basement and 3 rd floor attic • Early 1970’s third floor attic converted to office space • 1977 renovation added a building wing (North Landing side) • 1981 renovation improved heating, ventilation and air conditioning in third floor office spaces • 1988 renovations enhanced City Manager office lobby and City Attorney offices on 2 nd Floor • 2010 comprehensive building assessment (architectural, electrical/HVAC, and hazardous materials evaluation) • 2016 City Hall Policy Report and initiation of Planning and Concept Development Study • 2017 City Hall is 48 years old 2

  3. The Building Has Served Us Well ... 2010, comprehensive building assessment performed • – Waller Todd and Sadler, PACE Collaborative, and Geo Environmental Resources Comprehensive review of architectural, structural, plumbing, • mechanical, electrical systems, and environmental conditions Assessment identified specific deficiencies and included the • following statement: – The physical configuration of the building, in our opinion, does not allow for adequate compartmentalization to accommodate partial or phased occupancy during the abatement/renovation procedures. (The potential for public as well as employee exposure is too great to take that chance.) Under the best of circumstances, we are 5 – 7 years away from a • new or renovated building if we started today 3

  4. 3-072 City Hall Planning and Concept Development • $250K in FY2017 to conduct planning and concept development study • Study initiated in summer 2016 – Basis of Design (space requirements and adjacencies) – Renovation vs new construction; Municipal Center vs Town Center – Preliminary planning documents and programmatic cost estimates and schedules • Study to be completed by summer 2017 to facilitate policy discussions, public input and FY2019 budget submission • Current estimates for 140,000 SF of new construction range from $44M to $49M 4

  5. 2017 Is Our Year to “Decide What to Do” Significant Deficiencies Will Ultimately Lead to Failure of Critical Systems There Is Not A “Do Nothing” Option Let’s Take a Virtual Tour of B-1, . . . 5

  6. Asbestos Containing Materials Fire Proofing Applied to Upper Floor Joists 6

  7. Asbestos Containing Materials Mudded Pipe Fittings 7

  8. Asbestos Containing Materials Residual Above Drop Ceilings, On Ductwork and On Duct Vibration Cloth 8

  9. Asbestos Containing Materials 9” and 12” Floor Tile Throughout 9

  10. Asbestos Containing Materials Ductwork Joint Mastic 10

  11. Unfortunately, Asbestos Containing Materials Are the Least of Our Worries . . . • We will continue to professionally manage ACM containment. • Electrical, mechanical and plumbing systems are on borrowed time. Typical equipment lifespan(s) are 20-25 years, we’re now at 48. • When these systems fail, there will be no warning. Building will no longer be habitable. We cannot replace these systems without • comprehensive ACM abatement. 11

  12. Main Electrical Switchboard, Panel Boards and Service Distribution 48 Years Old 12

  13. 9 Air Handing Units AHU-1 Through AHU-7, 48 Years Old AHU-8, 39 Years Old AHU-9, Salvageable 13

  14. 117 Fan Coil Units All 48 Years Old 14

  15. Steel to Copper Pipe Joints Dielectric Couplings 48 Years Old 15

  16. Baseboard Hot Water Radiators 48 Years Old 16

  17. Aging Chill-Water and Hot-Water Pumps 17

  18. Plumbing Fixtures 48 Years Old 18

  20. Maintenance and Renovation Challenges (Just since I arrived in July 2015) July 29, 2015 – Broken hot water line under building required shut down of HVAC, causing • cooling of dielectric couplings and subsequent water leaks above ceiling when system was re- pressurized. November 25, 2015 – Lost HVAC service to Council Chambers for several days. Had to replace • AHU-1 motor. February 19, 2016 – IT initiated project to upgrade their Council Chamber Video Production • Facilities. Confirmation of significant asbestos above ceiling in Council Chambers has had project on hold for months. Can’t work above ceiling until space above ceiling is remediated. April 14, 2016 – While attempting to replace Conference Room 350 Video Projector with • enhanced equipment, discovered asbestos containment barrier failure above ceiling. Required extensive testing and air monitoring. Couldn’t replace projector. April 29, 2016 – HVAC mechanical room pipe failure, significant leak. • July 1, 2016 – Power outage caused chill / hot water pump valve switches to lock on hot water • side – providing heat instead of AC. Had to take down system. September 10, 2016 – Hurricane Matthew revealed failed pointing and flashing in City Hall • Chimneys. Water intrusion caused leaks above main stairwell, in City Manager’s office and Mayor’s office. Ceiling tile replacement should have been next to nothing, but asbestos containment and abatement was expensive. January 7, 2017 – Winter Storm Helena caused a Dominion Virginia Power outage, reducing • City Hall power from 3-phase to single-phase. Chill water pump burned up and needed to be replaced. 20

  21. No Back-Up Emergency Generator 21

  22. Physical Security Features Aren’t State-of-the Art Access Control Features • Exterior Doors – Lenel Onguard – Closed Circuit Television and Video Monitoring considered, but ACM has • prevented installation Emergency Alert Features • Other – Best Discussed In Another Venue • 22

  23. IT / Data / Video / Public Address 23

  24. Physical Space Shortfalls • B-1, 80,000 gross SF - 62,000 net SF of usable space. • Purchasing Office can’t co-locate with Finance • City Attorney Real Estate can’t co-locate with City Attorney • Council Chambers, Mayor – City Manager Spaces, Staff Admin Areas don’t meet today’s needs, let alone the needs of 50 years from now. • Need 123,000 gross SF today – we have 80,000. • Need 149,000 gross SF in 2070 – we have 80,000. • We’re short 70,000 gross SF. 24

  25. What Can We Do ? . . . Moseley Architects is helping us understand “what we can do”, not “what we should do” 25

  26. Moseley Study Scope Task 1 Development of the Building Program • Confirmation of the appropriate departments (provided by City Manager and City Staff) – Departmental surveys and charrettes • Development of square footage space needs, by department • Determination of required adjacencies and work flow evaluation • Assessment of ability to meet program requirement by renovating B-1, or if new construction would be necessary • Completed on November 17, 2016 26

  27. Program Requirements City Hall – Municipal Center 27

  28. Program Requirements City Hall – Town Center 28

  29. Moseley Study Scope Task 2 Preliminary Site Analysis Four options are being evaluated: • – Renovate B-1 and construct a new addition to B-1 – Construct a new City Hall at Municipal Center, adjacent to B-1 – Construct a new City Hall at Municipal Center, adjacent to B-2 – Construct a new City Hall at Town Center on City Property Evaluate site locations • Identify pros and cons of site locations • – Building size/setback – Storm water management – Parking availability – Availability of Utilities (electric, natural gas, water, sewer) 29

  30. Moseley Study Scope Task 3 Preliminary Schematics • Build massing/department bubble diagram schematics • Prepare conceptual elevations for new construction options – photos of existing facilities to demonstrate architectural style 30

  31. Moseley Study Scope Task 4 (Good Data Enables Good Decisions) Programmatic Cost Estimates and Schedules Programmatic cost estimates for all 4 options in the form of a CIP • “total project estimate” – Design estimate – Construction estimate (Site development, Demolition, Construction, Swing space) – FF&E cost – Contingency cost Preliminary schedules with fiscal year impacts • Gant Chart for all 4 options showing design, construction, and FF&E • Programmatic cost estimate to repurpose B-1 for use by Public • Utilities and ComIT (Data Center) in the form of a CIP “total project estimate”. 31

  32. Moseley Study Scope Deliverables (Built In Time To Make Best Decision) • Report addressing the Development of the Building Program (Task 1) completed 17 NOV 16 • Final Report addressing Tasks 1-4 by 01 JUL 17 • Moseley will enable us to understand “what we can do”, and the impacts of each option. • “What we should do” is up to City Council. 32
