The featured picture is one of our seismic skids donated by Magnum piering!  Thanks so much!  They are enroute to UCSD as I write.

We are slightly delayed, but I do have a signed and executed contract with the sand compactor, and he has agreed to be on the site on Tuesday, February 2nd to start removing the current tunnel test and recompacting the sand bed for the helical pile test.  So here is an updated tentative schedule as far as I know it.

February 2nd – Meet Cromwell Contracting onsite to start removal of tunnel and sand back to original 8′ level

3rd – Wednesday – Cromwell Contracting continues to remove sand and start to compact in instrumented lifts

4th –  Thursday – Sand Compaction continues

5th – Friday – Sand Compaction continues and should finish by early afternoon.

8th – Monday – Do an initial shake on the sand bed in the morning and then start Installing piles

9th – Tuesday – finish installing piles

10th – Wednesday – hook up instrumentation

11th – Thursday – hook up instrumentation

12th – Friday – hook up instrumentation

15th – Monday – UCSD CLOSED for President’s DAY

16th – Tuesday – hook up instrumentation and check everything

17th – Wednesday – possible first shake on just the piles (no weights)

18th – Thursday – start putting the top caps and all-threads on and add concrete donut weights

19th – Friday – add accelerometers to top of masses, check all instrumentation and possibly start the shaking sequences

22nd – Monday – start shaking or finish shaking the inertial masses

23rd – Tuesday – remove inertial masses and cut piles and place skids

24th – Wednesday – load skids with sand

25th – Thursday – finish loading skids with sand, place and hook up accelerometers and check instrumentation

26th – Friday – start shaking sequence on skids

29th – Monday – finish shaking sequence on skids and start removing instrumentation and piles

March 1st – Tuesday – finish removing piles and get Cromwell Contracting on the schedule for removing all sand from test box.
