3 Edmonton LRT System The Edmonton LRT System opened on April 22, 1978 first in Canada System currently carries close to 95,000 passengers on an average day Total line today is 21km long and includes 15 stations Combines underground and surface tracks with river crossing LRT trains operate electrically, which reduces air pollution from vehicle emissions and green house gasses LRVs are not impacted by winter weather road conditions

4 Current Project 3.3 km extension of an existing LRT System from Downtown Center to the North New 620m Tunnel Connection includes two major campuses, two hospitals and a major shopping mall Three new at-grade stations New bus transit center First stage of an ultimate extension to the northwest City of St. Albert

8 The Edmonton Winter Winter conditions from October to May Et Extreme low temps can reach h Celsius with wind chills in excess of Celsius! January 2011: 38 of snow in 28 hours Impacts equipment selection, installation, testing, commissioning, monitoring and operation Limited construction season

9 Outside Plant (Duct Banks) Frozen ground impacts excavation and stabilization Concrete and rebar cages have temperature t limitationsit ti Pre-pour inspections in snowy conditions Ice-filled conduits impact swabbing and mandrel testing Material specifications Job site safety

Outside Plant - Solutions Frozen conditions bar

slabs and track slabs Heated, rolling tent allows

at optimal conditions regardless of outside

10 Outside Plant - Solutions Frozen conditions bar normal concrete pours for duct bank cover, mud slabs and track slabs Heated, rolling tent allows concrete pours throughout the Winter Concrete cures at optimal conditions regardless of outside temperatures Safe environment with less concern for slippery conditions

Backbone and Horizontal Cabling Impacts Backbone (Fibre and Copper) installation scheduled for December-January to allow for on-schedule opening of the new extension Station cabling scheduled

11 Backbone and Horizontal Cabling Impacts Backbone (Fibre and Copper) installation scheduled for December-January to allow for on-schedule opening of the new extension Station cabling scheduled for January 2014 Special installation ti considerations Cable and Conduit Conditioning Must be in compliance with manufacturers installation specifications Lessons learned from South LRT experiences

Cabling - Solutions IP-66 rated cabling is required with

pullies, etc stored in warmed shelters Warming tents t

installation Conduits to be warmed prior to cable pulls

12 Cabling - Solutions IP-66 rated cabling is required with stated installation temperature minimums Cables, spools, pullies, etc stored in warmed shelters Warming tents t will keep cable from freezing prior and during installation Conduits to be warmed prior to cable pulls Temperature sensors will alert to unacceptable levels and cabling will cease

13 Security / Surveillance Systems Environmental considerations CCTV Hardware Door Hardware Electronics (mid-span injectors, network switches, media converters, etc ) Cabling Cabinets and enclosures Power-up considerations High wind conditions Snow accumulations

14 Surveillance Systems Solutions Arctic Integrated Domes IP-66 Rating NEMA-4/4X rated cabinets and enclosures Power-up Integration Reinforced mounting and shorter In covered positions where possible Enclosure monitoring by BMS Thermal imagery

15 BMS Temperature Monitoring Systems Temp Monitoring is Crucial! Temperature and humidity monitoring CCTV Camera Statust Access Control Track Blowers Heat Trace Heated Waiting Areas Glycol Platform Heaters Etc

Testing and Commissioning Testing and Commissioning

conditions may impact ability to test Follow-up

16 Testing and Commissioning Testing and Commissioning scheduled for January-April Outdoor testing during cold weather comfort and safety considerations Equipment startup in cold conditions may impact ability to test Follow-up testing has been recommended for later in the year to account for temperature fluctuations

Lessons Learned Local weather conditions have a

17 Lessons Learned Local weather conditions have a greater affect on all communications i systems and infrastructure than initially anticipated The conditions impact construction, installation AND operations Innovative methods to alleviate weather impacts are always welcome Semper Gumby (ever flexible) ALWAYS!

Summary The effects of cold weather are being

projects to improve the outcome Client support for

projects adds to experience for future challenges

18 Summary The effects of cold weather are being successfully mitigated Learning lessons from past projects to improve the outcome Client support for innovation is a key to success Undertaking extreme projects adds to experience for future challenges Documenting lessons learned helps to ensure future success!
