  • 1969: Building completed. 2 occupied floors with support

spaces and storage in basement and 3rd 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 2nd 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

  • 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

The Building Has Served Us Well ...

  • $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

  • 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.

Unfortunately, Asbestos Containing Materials Are the Least of Our Worries . . .

  • 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.

– Exterior Doors – Lenel Onguard

  • Closed Circuit Television and Video Monitoring considered, but ACM has

prevented installation

  • Emergency Alert Features

  • 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.

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

slide-26
SLIDE 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

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)

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

slide-31
SLIDE 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

SLIDE 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.

SLIDE 33
  • IT Department – Needs additional SF now and long-term

– Data Center is in the basement of B-2, susceptible to flooding – IT staff is dispersed in 9 different Municipal Center buildings

  • Public Utilities Department – Needs additional SF now and long-term

– PU staff is dispersed in 3 different Municipal Center buildings.

  • A “combined PU / IT facility” would require 77,000 gross SF

– Renovating and repurposing B-1 for this function looks like an opportunity

  • Public Safety / Police Department, B-11

– Condition of B-11 is very similar to that of City Hall – Basement and 2nd Floor of B-2 would make great swing space for B-11 renovation

  • Public Works Department – Needs more SF now and long-term in B-2

– PW staff is dispersed in 4 different Municipal Center buildings – Could consolidate using 2nd and 3rd floor of B-2

  • Planning Department – Needs more SF now and long-term in B-2

– Could provide better public service using entire 1st floor and basement of B-2

Could a New City Hall Provide Other Benefits?

  • City Council Retreat to discuss alternatives being considered and policy

issues with regard to the location of City Hall – February 2017

  • Moseley report / presentation to City Council – May / June 2017
  • City Council consideration of options and public hearings – Summer 2017
  • City Council and City Management consensus on preferred option – Fall

2017

  • Commence design of preferred option – Winter/Spring 2017
  • Completion of design – Fall 2019
  • Commencement of construction / renovation – Spring 2020
  • Completion of construction / renovation – Fall 2022
