Original Observation	Additional Info	Recommendation
1.	Tie-in piece was not secured by cribbing at both ends causing the pipe to shift while contractor was grinding the existing pipeline.	The tie in piece, which was lying on the ground, was not cribbed because it was not in a final position. During this time one contractor employee improperly climbed over the pipe causing it to shift.	During the pre-construction safety meeting remind all contractor and company employees not to climb over any pipe that has not been secured or cribbed in place. Stress to always think of the consequences to others of your actions during the job.
2.	The side-boom pulled an electrical cord that was running into an excavation while moving away from the work site.	A pump was placed into the trench ahead of the side boom above. The generator powering the pump was well behind the side boom. When the side boom moved forward a tread picked up the cord and moved it about 6-8 feet up over the tracks.	During the pre-construction safety meeting remind all contractor and company employees not to move any equipment unless they do a circle of safety check. Where needed another employee on the ground can assist with the circle of safety.
3.	Electrical cord in the excavation was wet causing an electrical shock.	The employees described as experiencing the shock were contractor employees. During the tie in nobody from the contractor crew or company crew said anything about anybody getting shocked.	Where and as needed to avoid any shocks or other electrical issues all extension and welding cords should be moved and protected to keep them out of the mud and water during tie in operations.
4.	Bypass was used to supply fire control stack at tie-in location #2, which could have over-pressurized tie-in section.	At tie in location #2 the high gas flow caused regs to freeze up. In order to keep the job progressing the gas was fed through the bypass and controlled at the fire control stack.	The existing regulator panel used by the District will be analyzed by the engineering staff to determine if the regs need to be upsized or changed out. In the interim the bypass will not be used to supply gas to the fire control stack.
5.	Employee slipped on curb because of mud on his boots.	Due to the rain everybody was wet and muddy at both tie in locations.	Remind employees to keep their eyes on the path and slow down during operations in wet and inclement weather.
	Original Observation	Additional Info	Recommendation
6.	Loss of communication between tie-in excavations.	Because it got wet one cell phone at tie in location #1 stopped working. Another phone was used to continue to communicate between tie in locations.	As needed ensure that spare phones or radios are available to communicate between job locations. Where possible use all weather radios if available.
7.	Concern regarding the fire control stack at location #1 affecting the other stack during the tie in.	During the seal welding the pit boss at location #1 incorrectly removed all the tape off the band at once when welding started. Initially this resulted in excessive fire at that location which temporarily affected the other location. The operation at location #1 was stabilized and both operations continued without affecting each other.	Ensure that work correctly follows the proper steps during hot tie ins. Attending other tie ins may provide additional field experience needed by some newer employees. Where needed revise standard 223.0165 to expand welding options and provide specific procedures to follow.
8.	Concerns regarding shoring; (unclear).	Proper shoring was installed at both tie in locations. Outside of the work areas there was no shoring.	Prior to any work all shoring should be inspected to ensure that a safe working environment is established. As needed work with the contractor to correct any problems or concerns.
9.	Plastic rain gear initially worn by some inside the excavation during tie in.	Once alerted by the pit boss, the DOM worked with the contractor foreman to have employees remove any rain gear not suited for use inside the excavation.	During the pre-construction safety meeting remind all contractor and company employees not to wear any plastic or flammable clothing inside the bell holes.
