All these pictures were taken from my home. Here we see trenching across the street to connect the new plastic line to the original steel supply pipe - still in use.
Here we see the workers connecting to the original line.
Trenched to the new outside meter location. The old meter is located at the center front wall of the cellar. In recent years the meter is read automatically by radio from a vehicle. Previously it was read by a meter reader monthly by entering the house and cellar. This meant you had to be home to admit the reader.
The meter removed from the cellar and newly positioned outside with new piping in the cellar.
The steel plates over the street trench just barely visible behind the truck. Work continues.
A closer view of the work on the line.
Preparing to cover the poly sheeting with the 2" top layer of concrete.
Ready to pour the top finish layer over the plastic sheet.
A New Year and the workmen are pouring temporary concrete in the cuts. With a thick lower layer they are now pouring about 2" over polyethylene sheeting to keep the layers separate.
Another view of the concrete pour. The cold weather was evidently not a problem. The steel plates to cover the hardening concrete are on the left.
Pouring the bottom layer of concrete.
It's now June 2019 and the top layer of concrete is being removed. The polyethylene sheeting is being discarded in bags for recycling while the concrete chunks are loaded in the truck.
Worker removing the polyethylene sheeting. They are putting the plastic into the black trash bags for recycling.
Pouring the hot mix asphalt, replacing the removed top layer of concrete.
Another view of the cut finish. The 'Bobcat' was indispensible to the work - always on the move.
The machine applying the blacktop to the long street-side cut in a smooth layer ready for rolling.
Bobcat giving the asphalt spreader a refill.
Pouring mix for the final finish of the cross-street cut.
Continuing the pour. The gas powered portable tamper is in the foreground.
Tamping the edges of the paving before it will be finished with a large roller.
Original: July 2019. It turned out to be a larger project than I had supposed to replace the aged steel gas line (the original was 'blown out carefully, sealed' and left in the ground). The crews worked diligently throughout the winter - surprisingly they had no problem with the temporary concrete curing. All in all, nicely done. National Grid still has a Herculian task remaining with old lines.
