Grading: 2/7 - 2/14



Broke ground 2/7. Jon Watson (grading sub) couldn't start until the 13th so Heyday executed the job ourselves. Rented a Cat 314 excavator and a sheepsfoot compactor and had operator Joe work the excavator. He brought a friend to drive the compactor on Wednesday, but that guy didn't know what he was doing, so Balta took over for him. Joe couldn't work after Wednesday, so he sent Robb and Robb worked Thursday, Friday and Monday.

2/7 Tuesday - REMOVAL Joe on excavator, cut 3' pads 1 & 3. Balta on water. Reza bottom inspection, Valenzuela City inspection on bottoms.

2/8 Wednesday - COMPACTION Joe, friend on compactor, Balta on water, began compacting.
Compaction went poorly as there was a very wet spot on W side of Pad 3. Messed around with that a lot, but got most of Pad 1 filled. Shant Minas (AES) continuous observation backfill.

2/9 Thursday 10hrs- COMPACTION Hardy&Robb on excavator, Balta on Sheepsfoot, Robb on Backhoe. Received four loads of CMB from Shamrock. That solved the wet problem. Brought in a backhoe at 1 as it was obvious the excavator needed help placing smooth lifts for fill. Got 1&3 done/backfilled. Fareed (Applied Earth Sciences) continuous observation backfill.

2/10 Friday 9hrs - REMOVAL No Hardy (Orlando) Robb on excavator. Called off the backhoe at 1 (24 hours). Robb got all of Pad 2 and half of pad 4 removed.

2/13 Monday 10hrs - COMPACTION Robb, Hardy, Balta (backhoe, excavator, compactor). Got pad 2 filled, excavated remaining pad 4 and got pad 4 filled. Great teamwork to get a lot done during the day. Backhoe helped a lot. Called off all three equipment.

2/14 Tuesday FINISH GRADE on Pads 1 & 2. Medina sent two guys with a Bobcat. They showed up at 9:45 with no laser. Alex came at 10:30 with a laser level and we laid it out. I stopped by at 1:30 and they were done with pad 2, starting pad 1. They used the compactor on it.

Pads 3 & 4 are one foot low, so we will use the footings spoils to raise them up later.
Lowered Pad 3 elevation on drawing 0.4' per conversation with Kevin.
