more difficult time because it can vary across the trade. >> early on we were having a lot of difficulty with operating engineers. because it is the fifth man on the job is supposed to be an apprentice but that is by subcontractor, and most of the subcontractors, they were having two or three pieces of equipment in operation, so they were never getting to that fifth individual. and so the numbers were quite low on the operating engineers just because the number of operating engineers under any individual subcontractor was not very high. and you don't want to have an apprentice out working a piece of heavy equipment if they are not, you know, in the right accompanied by a journey person. so, that was the place where early on we had the most difficulty meeting the percentages. >> thank you. >> and all right, and i would
12:26 pm
like to say thank you bob, to give us an update on construction. >> we have a couple of good milestones reached this month. there we go. and another 35,000 craft hours, approximately over the last period from the previous report. and again, a great safety record, everybody is working really hard on this and no recordables and no incidents of any serious nature since last september and we have been fortunatelying 35,000 craft hours a month and that is almost 200,000 hours now and getting close to that where we have gone without injury and knock on wood. we hope to keep that up and the bracing work and the excavation over all is about 65 percent complete. and we have seen great progress on that in zone one about 87
12:27 pm
percent complete, zone two, micropiles have started and are at 16 percent complete, and to date, none of the micropiles have failed in their post installation testing so that is moving along very well. again, big highlight and construction site is just this last weekend with the bridge installation, no complaint. and we got that going on monday, so the team particularly web corp and the subcontractor did a great job on that and certainly the neighborhood appreciated it and most of that is over. the ground system and the geo thermal started this week with the first installations in the west end in zone one and in zone four, and i will show you the picture the buttress contractor is completely gone now. so that picture changed yet again, unlike the other times that i showed you the picture
12:28 pm
and it never changed. >> a big milestone on the auxiliary water system, between first and second street, started at second and worked east to first is nearly complete. there are intersection work to be done removing the steel plates and redoing the streets and now they will work the way and the next milestone is to get from first to freemont complete. they are trying to get the water line into where all of the other existing pipes are. some are supposed to be there and some weren't. so that continues to be a challenge, but they are working on that as well and they have that part. >> the next 90 days, you can expect to see the remaining mud slaps in the zone one area up to approximately shaw alley to the west end and the water proofing and the rain forest should start in zone one with
12:29 pm
the first tentative map poured for sometimes june coming up and of course, the buttress platform will be into zone four by the next meeting or in the next 90 days but certainly by the next meeting. the over all time line has not changed we have the anticipation of 2017, and we are providing the key milestones and that is the same schedule that you saw previously and we are incorporating the monthly update and this is through the update that we last reviewed which was the february one and march comes in at the end of march to us and we are in the process of reviewing that before we publish those dates and there are no surprises that have been brought to my attention and i am still targeting that october 2017 bus
12:30 pm
operation date. >> these will change and it will have a slight change and as we get through the rebid issue and things like that. but we will try to mitigate. >> the time line and all that is left is the excavation and they are on track to finish in 2014 is the plan. this week and next, they will finish out the sidewalk with a temporary bridge and that will be done shortly, but the bulk of the work remains with the excavation and installing the micropiles and the mud and turning the area over as they complete it. so we got this graphic to start tracking the below grade or structure schedule and of course, it is starting with the grounding and geo thermal work that will move on to the vertical and horizontal water proofing and the actual map slab, and so on up to the trained box walls and the lower concourse slabs and the starter wall above the lower concourse
12:31 pm
where they will turn it over to the super structure concrete contractor. >> the excavation map that we have brecken into the two zones and make it easier to read and zone one is considered from the west end and the excavation is 100 percent complete and you can see in the lower left-hand corner and the completed slabs and you can see the micropiles, and they are the completed ones and the red one are still to be completed and of course the bracing diagram gives you a good graphic of how we are completing the work from west to east and how we are maintaining the progress and in the east end, starting at first street and running across the street. and the same information zone two is almost like 99 percent bottomed out in the excavation in zone three and well into the
12:32 pm
lowest levels and we would expect the change in the zone four where they have completed and the trussle appears to be put in and they start to build in the trussle and connecting it to the bridge and start the excavation in earnest in zone four. some photos to run through here, the comparison photos of the central and western ends of the project, it is hard to tell the progress, but if you look closely, you can see that the photo on the right, the place between it the hole has gotten deeper, if you look carefully you can see the bottom of the hole. this is the micropile chart and you can see how the lines are starting to get closer together and we got off to a slow start with the weather in last december. but it is rapidly picking up speed and keeping up with the progress of the project.
12:33 pm
just to give you an idea of what that all looks like, the upper left-hand corner photo is how they test the pool test and that is the test rig there and installed and of course, on the right-hand photo and the finished pile is waiting for the mud slab. >> we have to prepare the subgrade. and prepare the subgrade for the mud slab and sometimes there is depressions in the final subgrade that is what the gentleman there are doing and getting it all graded off and ready for the next mud slab pour and into the zone two and three bracing and excavation shots. again, zone four picture there is the rest of that is gone, and the red tanks have to do
12:34 pm
with the bridge peers. and you have to clean up. but the rest of the buttress and everything and the trailer and the water tanks it is all it is all out of our lives. >> and under budget. >> fun. >> there is just that the access trussle is coming in zone four. it is for the baoel street bridge and they literally cut the line down and tying that into the abutment and the foundation of the end of the bridge where it lands and installs the bridge peers and there is the bridge being put together and ready for the hoisting and we have actual photos from the weekend here and i do want to show you the awss progress and the work
12:35 pm
trying to cover up on first street between second and first and the paving and asphalt getting done on that run, which gets us out that have busy part of the street and into the next session. and so, with the baoel street on friday night, and a little bit late start and they had a small equipment issue that set them back and it came through and got them done on schedule and opened the road back up on monday morning and i was told by brian that it was 4:44 in the morning and that was his lucky number, it was around 4:40 in the morning with the obligation to have it done by five. and most of it is installed and what it looked like on saturday night and sunday after paving. what extended the time on baoel street, of course, it is hard to see in these photos, but in the lower portion on the dirt side, there were the two red rains are, there were two pools
12:36 pm
that needed to be reinstalled to restring the lines in the bridge configuration and that extended the time into sunday and early monday morning. and this is the time lapse of that friday night. and did it stop? >> well you have seen the time lapse before, very similar to what we have done in the past, you can see the bridge sections doing in and it was a well coordinated activity and we got a lot of help from the city
12:37 pm
folks and the street folks and made it a very successful weekend. >> the other information, in the report, that you have on your screens, i believe or has been handed out is the labor reports of the increased hours are still trending in the scene for the local labor including 24 percent, the san francisco labor and the numbers continue to go up and i would approximate, and we are working two shifts and a modified swing shift, but, i think that is the end of the report. >> any questions? >> yeah, we have a question on this. it is for the director, the schedule for the steel package shows that we have 0 float. >> yes. >> and we are losing probably many months for what is probably the right call to
12:38 pm
repackage and put it back out. but when we will have it and a recovery plan and a revised schedule. >> we are actually starting to meet with web corp on that right now. the key to looking at the over all structural schedule, is what is critical were the cast notes because of the fabrication time, within one to two months actual getting it in and starting the shop drawings and the steel becomes critical as well. if we can get it out in play and it will bring it to you next month and we will still lose about 30 days off of where we wanted to be which was our original intent was to have a reward at this meeting. we are going to have to make-up time and there is lots of opportunity in the trade
12:39 pm
packages and now that we make it into three production and erection teams. it is definitely going to be a challenge, in the short term. which hopefully we can manage within that trade. and then, also, pick up what we need to in the future trades as well. >> but it is something that we are looking at right away. >> yeah, just more on the structural steels. i agree that it seems like it is worth rebidding. >> that is the last major opportunity that it sounds like to cut costs. when will we know how that has turned out? and breaking that into three packages. >> putting out the packages around the 25th of april.
12:40 pm
the twenth. and the 60 day window and assuming that there are not any major questions that come up, the guys have seen the material before. and it is a 60 day window. and we are hoping around the 20th of june and be able to present the packages and the bidders to you at the july board meeting. >> okay. >> that is the cold in which case they could get kicked off in mid july and august first and we will get a better view from the actual participants where they can cut the time and too conservative and 0 in. >> and in terms of the three packages they are not phased so that you need somebody to work on the first piece before the other ones can determine the prices. >> good question, the way that we are looking at it now and the way that web corp has
12:41 pm
suggested and it is a great method is basically west end of the center session and east. and in the original scenario, the single contractor, would have started to cruise at what we call nine ten, which is approximately there is an expansion there and it says approximately the zone one to zone two dividing line around shaw alley and to the east of that, there will be two crews starting there. but now there will be the same thing and one of them may be, let's say steel and the other one may be a chef steel and they will have the only section to work, and then in the third competitor, and again, it could be all of the same guy, depending on how it shakes out in the bid and we are offering that opportunity as well. but presumably, as the other team approaches that joint, they will go to another expansion joint and that is where the other contractor can
12:42 pm
start off. >> that is down around line 20, 21, and works east to there, to the end. >> we always knew that area was going to lag behind any way, but that is because the buttress had to be behind zone four, that is always lagging behind. >> so, part of the theory about why the bid came in so high, obviously part of it is just demand in the economy. >> market environment. >> part of it was the premiums being added in because of the uncertainty about how it was going to play out. >> there was all set in the competition played a huge part.
