Additional information requested by potential bidders

Clarification regarding confined space requirements:

The culverts are a permit required confined space. However, due to the atmosphere not being subject to a sudden change leading to an atmospheric hazard, the workers do not need to be continuously attached to a retrieval line. Continuous air monitoring and a procedure to immediately evacuate the culvert if the air monitor hits an alarm point is sufficient.

Rescue crew shall consist of sufficient workers outside the workspace to initiate rescue from the local fire department and enough workers to extract an incapacitated or injured worker from the conduit using the retrieval line.

When going up and down the ladder to exit/enter the conduit fall protection is required.

A confined space entry plan will be required as part of the Accident Prevention Plan that is part of the pre-work submittals.

RESCUE PLAN CHECKLIST

What do you do if someone falls and becomes suspended toward the top of the tower?

Would you know how to get that person down? A rescue plan helps everyone understand what to do before a fall.

Following are some important components of a rescue plan.

Gain an understanding of the physical environment you will be working in.

Determine the proximity of a professional rescue team.

Determine if 911 works from the area where you would be calling.

Determine approximate response time for 911 responders.

Understand the type of rescue that may be necessary (lowering a victim from a ladder, platform or manbasket).

Determine who is trained to do the rescue.

Decide if the rescuers will be on-site or stand-by. If stand-by, determine the response time.

Perform a job safety analysis of the rescue.

Is the victim clear of obstructions when s/he is lowered?

Does the lifeline deploy correctly?

Is the lifeline long enough?

Can you see the victim throughout the entire rescue operation?

In addition to having a plan, it is also important to have rescue equipment and supplies on site and ready to be used.

Rescue devices that can raise or lower a victim, such as a controlled rate descent device

Ropes and lifelines rated for rescue and evacuation

Rolling edge protectors or Velcro edge protectors to protect the rope from sharp edges and abrasion

Designated anchor points for rescue equipment (rated at least 3100 pounds)

Anchor straps and carabiners for making an anchor point when one is not available or convenient

First aid kit and defibrillator
