8:30 - 9:50 am
Windy with scattered showers (Heavy rains previous evening)

It has been several weeks since the last update to this blog. According to best practices I am not meeting the frequent update quota of 1-2 per week in order to be a successful blogger. That will change. I am going back to the one-a-week or more postings.

Last night we had sever rains and some flood warnings. There appeared to be de-watering taking place in several locations. The main collection area is at the center of the southern area. The eastern part of the site is being prepared for panels while the western part seems to be finishing. The project appears to be divided into four major sections.

This mornings erection of the precast panels was slowed slightly when a JLG lift had to be pulled out of the mud by the crane.

I watch the crane from about 8:30 to 9:45 while it lifted a panal in place and then lifted the JLG out of the mud.

8:36 am: Crane positions for hoist (2 min)
8:38 am: Crane connections are made to panel (2 min)
8:40 am: Liftoff + hover
8:45 am: Panel is walked toward set location and held (approx. half way)
8:53 am: Panel is hoisted to final position
8:54 am: Panel inserted and adjusted
9:32 am: Cables unhooked from panel
9:37 am: Rigging of JLG lift begins
9:41 am: JLG liftoff from mud
9:44 am: JLG lift set

The job seemed to lose about 10 minutes of time by having to relocate the JLG lift. While it may seem minor 4 workers were needed to rig and coordinate the movement. I'd like to think this delay could have been avoided if the lift had been left on the sidewalk in advance of the previous night's storm.




In addition to this delay the crew for the lifts appeared to comprise of:
1 crane operator
2 riggers
1 welder
