Preparing the Work Area on Top of the Salisbury Jetty
The top of the jetty has have a rough uneven surface especially in areas which have been damaged by years of storms. The excavators need to travel from the beach to the outer sections of the jetty to work on repairing it. They place rubber mats (made from old tires) on top of the jetty to create a more stable surface to travel on. The safety of the excavator operations and other construction personnel depends proper placement of these mats to made a safe road surface. This video shows an excavator moving the mats around. I am impressed with the skill the operators have in moving, adjusting, and repositioning the mats into the correct position.

Excavator Working on Stone Staging Area on Beach
When the stones arrive by truck, they are initially taken off the flatbed and placed in a pile nearby. Subsequently the stones are moved and reorganized into other piles before being transported to the Salisbury jetty. This video was taken from beach side of the construction area near the fence. It shows one of the excavators reorganizing the stones. In the background you can see two excavators working on the jetty.

Some General Views of the Construction Site
The ever present "construction supervisors" keep a close watch on progress.

This is the beach area next to the parking lot. It is used for unloading the trucks of their stones and piling the stones in the staging area.

Creating a Level Top Surface on the Jetty
This video shows how those huge flat stone blocks are being used to cap the top of the jetty and create a level top surface. Some of the heaviest granite blocks are being used for the top of the jetty which generally sustains the worst of the breaking waves during a storm. The excavator uses small stones to raise the base level that flat stone blocks will be placed on. Sometimes, the height isn't right. In this case, the excavator tries twice to position the stone block but it is too low. So the block is removed and more small stone is added to raise the base height. Good video showing the details of how the capping progress is being done
It was a rather winding day and the camera was being blown around a bit.

Stone Block Handoff
This is continuation of a series of videos showing the excavators working on the Salisbury jetty. In this video the first excavator is bring out a huge flat stone block. All goes well until the tractor drops it (oops!) He picks it up again and has a better grip on it. You will notice how slowly and carefully the excavator drives out onto the jetty. Very safety conscious. The block of stone is probably about 18 or 19 tons in weight. Once the excavator gets out to the area being repaired it puts the stone down and the second excavator grabs it.

Excavator with Claw Brings Stone out to Jetty
Two excavators with claws were working on the Salisbury jetty. One excavator brought large stone blocks from the staging area on Salisbury beach out to a pile on the jetty. A second excavator was using the stones to cap the top of the jetty.
Second excavator was being used to position the large flat blocks as capstones on top of the jetty.

Excavator with Bucket Brings Out Small Stone to Jetty
The construction crew has three excavators with claws and one excavator with a bucket working on the Salisbury jetty. The excavator with the bucket is used to scoop up small stones and bring them out the jetty. The small stones are being used under the large stone blocks to raise them up to the correct height and to level them. Large flat blocks are being place across the top of the jetty to cap it and create a level top surface.
The stone is brought in by trucks and stored in a staging area on the beach before being brought to the jetty.
