## Logistics and Practical Aspects of Construction of a Large LAr Tank in a Remote Location

- FLARE Workshop
- November 5, 2004
- Elaine McCluskey
- Fermilab FESS/Engineering

## POTENTIAL CONCERNS

- Proximity to transportation networks
- Proximity to existing utilities
- Proximity to capable workforce
- Proximity to available materials
- Duration of construction – need for temporary facilities
- Security issues
- Winter weather impact at proposed site
- Environmental considerations and processes

## PROPOSED SITEabout 30 miles northeast ofFort Frances, Ontario

## Proximity to Transportation Networks

- Important for
- Delivery of construction materials
- Delivery of argon over extended period
- Ability of installation workers (experimenters and other technical workers) to easily access the site
- Requirements include
- At least a state highway-type access road
- Possibly a rail access for argon delivery
- Be near an airport

## Proximity of Existing Utilities

- Utilities likely to be required for this facility include
- Electricity
- Potable water
- Data
- Likely to have first construction package as site preparation to construct access road from nearest main highway and to bring all utilities to site to facilitate temporary construction facilities

## Proximity of  Capable Workforce

- Site preparation, tank, and associated facility construction will require a diverse workforce skill set
- Excavation
- Concrete
- Steel erection, including possibly specialty tank construction workers
- Pipefitters
- Electricians
- Although not in a major metropolitan area, proposed site is near Winnipeg, Duluth, and Thunder Bay, plus in the vicinity of mining/manufacturing operations
- Therefore, qualified workers should be available for this project

## Necessity for Temporary Facilities

- More remote location may require temporary housing/offices/security/convenience facilities
- Location of Fort Frances 30 miles away is equivalent to living in Chicago while constructing Fermilab – inconvenient, but doable, eliminating need to construct and manage temporary housing
- Offices for construction companies, project management, security, other entities
- Comfort facilities including toilets and showers

## Security Issues

- Remote site will require
- Fencing around site and secure access to keep both unwanted wildlife and people out
- May also want to have security services, at least during construction and installation

## Winter Weather Impact

- Construction in Ontario during winter
- Site utility construction likely not feasible during winter
- Concrete construction would likely be halted
- Tank welding could continue in winter weather

## Environmental Concerns

- Environmental Assessment
- Canadian process for requesting use of land requires application for use of land which includes environmental assessment
- Environmental issues may include
- Release of argon gas to atmosphere – options for mitigating this potential hazard include
- Berming to contain full volume of gas during release to atmosphere
- Providing double walled containment capable of holding entire volume to prevent release
- Work in environmentally sensitive areas (wetlands, wildlife habitat) and mitigation thereof.  Actual site selection influences size of this impact.

## Next Steps

- Site Feasibility Study
- Task local engineering firm familiar with the area to do site feasibility assessment, to include
- Soils analysis for structural and environmental
- Analysis of nearby utilities and ability to meet project requirements
- Potential routing of roads/rail spurs
- Identification of potential environmental concerns
- Preliminary cost estimate for site development
- To initiate this requires
- Project identification of power/water/site size requirements
- Funding source at approximately $50k
