BACKGROUND

History of Community Centre BACKGROUND

1972 Construction start of arena 1972 Wood structure revised to steel alternative 1989 McEwen Report 1992 Expansion of Community Hall, Repairs to Arena 2010 AECOM structural report 2014  Greer Galloway structural report 2018 McIntosh Perry structural report

• Chloride salts found in original mortar
• Block wall deterioration
• Brine leaks under rink slab
• Block wall deterioration
• Brine Leak
• Assessment for re-use of existing structure

Re-Using Existing APPROACH

2014 Greer Galloway Report provided a cost estimate of $2.4M to retrofit the existing arena The analysis did not include areas that were inaccessible (including foundations) The IPD team had Mcintosh Perry review the existing conditions to assess the scope of work for structure re-use / expansion

Re-Using Existing Evaluation

• Can the foundations support the additional roof

load (code, new insulation)?

• Can the structure support the

additional loads of the roof and walls (insulated)?

Foundation Evaluation

Foundation Evaluation

Foundation Evaluation

The IPD exposed the foundation to the footing and found:

• The existing footings were smaller than the 1972 design
• requirements. (Underpinning required)
• The piers at columns are not salvageable (constructed

primarily to limit frost damage)

• The original foundation is the chloride contaminated block

and is deteriorated (not salvageable)

Structure Evaluation

The IPD team’s structural engineer assessed the steel structure and determined:

• Corrosion continues to be an issue with the

existing steel

• Re-use will require reinforcing & remediation.
• Existing block wall is deteriorating
• Frame would need to be dismantled & remediated.

Options Revitalization

Two key options:

• 1. Re-Use Existing Steel Frame
• Underpin existing footings
• Replace existing foundation walls
• Replace existing piers
• Reinforce and repair existing steel.
• Dismantle and remediate
• 2. New structure

Revitalization Cost

COST OF RE-USE: $905,000k 185’ rink COST OF NEW RIGID FRAME: $1,583,619 COST OF NEW ‘FRAMELESS’ $1,118,437

Options Revitalization

Building envelope thermal efficiency: The higher the R-value, the greater the insulating effectiveness.

PROGRAM Key Spaces

GOALS

• 2010 AECOM report identified a potential

extension of the existing rink life to 2035 (17 years remaining)

• A new structure will provide a life of 40+

years (beyond 2060)

Durability

GOALS Sustainability

• No prerequisite credits
• More flexible material use
• Goals for GHG reduction, energy

efficiency, Indoor Air Quality.

• Prerequisite credits
• More prescriptive material use
• Goals for GHG reduction, energy

efficiency, Indoor Air Quality.

• Detailed documentation.

GOALS Sustainability Certified Projects (78 in Ontario)

GOALS Sustainability

• 3 Green Globes
• Integrated Design Process
• Energy Efficiency
• Environmental Impact
• Waste Management
• Indoor Environmental Quality
• Sustainability Performance Assessment

GOALS Sustainability

• Replacement of uninsulated structure to better

performing structure

• Use of high performance fenestration systems
• Use of high efficiency building systems equipment
• Use of water efficient fixtures
• Stormwater management, reduction of run-off
• Mitigation of light pollution
• Ventilation and exhaust measures for indoor air

quality

ASSESSMENT

ASSESSMENT facility  Reached a critical point for the existing facility’s

life cycle

• Inadequate ventilation (ammonia plant safety)
• Accessibility (compliance with AODA in 2025)
• Address recommendations from TSSA review
• Doing nothing is not an option

programs  Arena programs will be down for the duration of

construction

• Upper level Community Centre programs and

events will be impacted for a few months to connect the new addition to the existing facility

ASSESSMENT New vs Refurbish

Source: Inspection Report – SG Nesbitt, Minden, 2014 by Greer Galloway Consulting Engineers

Report does not address:

• Foundations
• Remediation of rigid frame
• Cladding to protect new wall

ASSESSMENT New vs Refurbish

AODA compliant facilities 40 year durability Hockey Canada compliant rink Modern, efficient ice plant Improved ventilation Connect scout room to facility Improved security through office centralization Accessible drop off Safer parking areas Sprinklering existing (asset protection) Code improvements New Refurbish Accessible connection between 1st and 2nd floor Energy efficient building Certified sustainable design

ASSESSMENT Construction cost

ARENA + LOBBY: $8.64M RENOVATIONS: $0.4M ACTIVITY SPACE (GYM): $2.81M SITE + LANDSCAPE: $0.64M

ASSESSMENT Cost options

$3,520,000

• Gym+Lobby Value

$360,600

• Addition Cost to Rink

$880,800

• Premium to phase
• Additional cost to

defer to start in 2021

$4,909,000 (x 3.1%) = $152,100 $5,061,100

• Additional cost to

defer to start in 2020

$4,761,400 (x 3.1%) = $147,600 $4,909,000

ASSESSMENT Cost options

$85,500 $23,000

• Reduced cost for 185’ Rink
• Reduced changeroom

sizes & amenities

• Additional landscape costs

for reduced footprint

$8,500

185’ rink in lieu of 200’ rink

• Net savings

$100,000

QUESTIONS structural  If we delay, how much longer do we have before

the building department shuts the facility down?

response  2010 Aecom Report: list recommendations to

extend working life of the building, also notes the arena to be re-inspected in 5 years

• 2014 Greer Galloway Report: notes major

restoration required within 5-8 years (Ie. 2019- 2022)

QUESTIONS inflation  If we delay, historically what’s the inflation for

the costs?

response  Year over year: 3.1% (Source: Hanscomb & Stats. Can.)

• Market driven statistic
• Approximate cost increase to delay entire project:
• For a 1 year delay, to start in 2020: $387,000
• For a 2 year delay, to start in 2021: $787,000

QUESTIONS consultants  What are the architecture and engineering costs

moving past Validation?

response  $ 305,130 (Source: Line 1a of Class C Cost Estimate)

• Plus attributable portion of Risk Pool

QUESTIONS

• perations  What are the operational cost increases?

response  Additional staffing cost $70,000

• Anticipating energy costs to be neutral through

energy efficiencies savings

• Anticipating lower building maintenance repair

costs, to be offset by annual increase contributions to reserves for future capital maintenance

QUESTIONS maintenance  What are the maintenance costs required to

keep current ice plant operational and safe for another one to two years?

response  Approximately $250,000

• 1996 Chiller replacement ($100,000)
• Evaporative condenser replacement ($85,000)
• Dehumidifier replacement ($35,000)
• Compressor rebuilds ($10,000)
• Piping/valves/labour ($20,000)
