Week 31, Part 2- Mechanical Tent

Now that rain and snow have subsided, Challenger Electric took down their camping tent and started working in open air- at 0-dark:30 under lights-



Setting up our Motor Control Center is the most critical aspect of electrical work on the project so the crew spent quite a few hours in this small space over a couple weeks!



Eventually they started running conduit west out of the Blower Room into other areas of the Mechanical building, even as scaffolding went up around them-



Speaking of scaffolding- while the electricians were busy at ground level and roof was under construction at Operations- R&R Masonry prepped for CMU walls at the Mechanical building. The first task was setting up full-height scaffolding and covering it with a tent due to cold weather. The blocks and mortar need minimum working temps for quality construction (40F)-










Light the propane heater and pop that roof up!

This completes a review of the week before New Year’s Day. CMU block wall construction will start first thing next week.

In the meantime, during the extended cold snap we developed an "ice cave" near the Effluent Lift Station. The dewatering hoses had a few pinholes due to rough conditions on the job site. The slight leakage created some interesting ice formations-






And finally a general view of our situation this week while the decking was still under construction at Operations and the Mechanical building tent was in place-
