trying to drill further into the hole, they have to rotate the casing. whether it is every hour or every 15 minutes or a couple of times in the middle of the night, they will have to rotate the casing. we will talk about that in a minute, but that is due to the fact that they are 240 feet down of a steel casing, and they cannot afford to have that lock up or freeze up because of the pressure. they will be using two rigs at the same time, two 10 or 12-hour shifts, and a swing shift that will go back and forth in an attempt to get back to -- we plan to have a production rate of 2.5 shafts completed per week, which runs the schedule out to 83 weeks. that is a total of 207 shafts in 83 weeks, which gets the work done in april 2013. we plan to start this on august 29 with the first hole getting started that day.

again, as i said, the two shifts during the day, there will be a need to rotate the casings throughout the weekend. the drillers as if they are above the halfway mark, they can probably leave it and not turn it in the middle of the night or on the weekend. if they are below the halfway mark, certainly, they will have to come in and rotate. whether it is every 15 minutes or once an hour or every other hour. another feature of the work is the traffic bridges and the trestle bridge that will run the length of the project. basically, the objective is to maintain traffic on first, fremont, and beale street, with a minimum of three lanes and the pedestrian lanes. in addition, in the east/west

direction, there will be a 30- foot trestle bridge to allow them to have equipment operating to assist with the excavation process. this shows you the layout of the trestle bridge running the length of the project, and also, you can see the cross lot bridge. they basically need to bring all the soil up through those cross braces using a crane up on the trestle bridge to do the excavation. they can go about 15 feet at a time, and then they start putting the bracing in. this is the actual excavation running from early next year, second quarter of next year through the end of 2014. they will start at the west end and work towards the east. that is primarily because in the east, we are still doing debauches pile doing the buttress piles. as i said, there are five levels of live skit that need to be incorporated at each one of

those various levels. right now, the plan is to conduct the excavation in two shifts. with the bracing going on basically during the regular daytime -- there would be some noise associated with that. be welding. possibly welding on the lot ships. it depends on the schedule. just to put that information in a graphic -- here we are on an july 2011. that is the intersection on the north side so we can do the assuring wall on the east but chris. by october, the shoring wall the east end should be completed.

that is the blue. the retrenching will be pretty much completed around the west end. and in january, the cdsm wall pretty much complete. it allows us to continue construction on the west and. then we start working on the traffic bridges. in july, the plan is to have all the traffic bridges in. you can see the excavation proceeding all the way up to be buttressed area. by the beginning of 2013, the excavations are complete down to

fremont street and to be buttressed area. it is completed, and the excavation is finally complete in 2014. the thing to note is in the west and, the whole excavation has to be complete before they can start the foundational work. this is just focusing on the work. so, if i can answer any questions? vice chair ortiz: are there any questions? director kim: we are starting to get information about this from the residence. if you could talk a little bit more about the sound of the rotating casings? >> sure. in reality, the sound of the casing rotating is minimal. is a high rpm diesel engine.

it would be comparable to comparablea bus revved its engine. i do not know if that is considered low or high frequency. the noisiest pop -- the noise is part of the operation is when they inject air and then have to do that fairly quickly. they take the case in al. they set it aside fairly quickly. the current plan, the ideal situation is all that concrete is place in the morning. what we consider a swing it shipped until 8:00, 9:00, 10:00. no promises. they may push that. the thing to remember about concrete pouring is once you start, you cannot stop. we are not allowed to add a

joint in any of these buttresses where the concrete hardens and you add it later. you cannot do that with this. it takes eight hours to 10 hours to pour. the plan right now is to get all those started in the early afternoon and finished them before the late hours. director kim: you think that could happen once an hour on the graveyard shift? >> the worst case we heard so far is a couple times and our. i was on a phone call with a driller last night, he reiterated that they may not have to do with all, but sometimes every few hours. director kim: my next question was -- this will primarily be covered during day shift? >> i might have confused you there. the excavation will go on in two ships.

that will be day and swing. swing those into the 11:00 hour. the big noise is setting them in place and rattling them around. the excavation is truckthe welde evening hours. with the ambiance traffic noise you probably would not hear a welding machine. director kim: ok. thank you. vice chair ortiz: any other questions? >> thank you, vice chair. that concludes my report. >> vice chair, directors, we have not received any communication of public suggestions on it that's item. vice chair ortiz: ok.

let's go to the consent calendar. >> ok, we will go to the consent calendar. directors have not received any indication that the public wishes to have any items sever. your items including the minutes of the june 9, 2011 meeting and item 7.2, authorizing the executive director dick skewed amendments to extend agreements for state abacuses service sees -- for state advocacy services with options remaining to extend each agreement for an additional three years. vice chair ortiz: is sarah -- is there a motion to agree to the consent calendar? can they agree even though we are not here? >> [unintelligible]

[unintelligible] >> i will second it. >> he was not here either. >> thank you. >> do you want to consider it separately? vice chair ortiz: whatever. whatever is easier. ok, so we are voting on 7.2 first? >> the minutes. vice chair ortiz: is there a motion to approve the minutes? director kim: so moved. their minutes -- >> their minutes --

implementation of the program, as well as document management and administrative support. there were ancillary projects of bus storage and bus ramp construction. we had a first three-year term that ran from 2004 until 2007 into 2008 for the first three years of the program. that was renewed in 2008, and it is here for renewal again. the rfp did provide for only two renewals, so this is a contract we will need to put back out in the future. term of one was initially

authorized for $37 million and actual performance over term one, due to demands over those first three years, the total amount expended was $23 million. overturned $206,000. we have expanded roughly $31 million under that contract, and the spe performance was 32%. at the end of each term, we go through a performance evaluation. the team continue the commitment of quality personnel and staff members, the performance and working relationships with the various stakeholders and members of our consultant team.

the adherence to the annual work plans and task orders, both schedule and budget, and the quality of the liberals -- deliverables. we are bringing back the contract for renewal with the recommendation for renewal. i can take any questions. vice chair ortiz: are there any questions? i see there has been a motion. is there a second? thank you. ok, and members of the public, anything you want to address on that item? we will take a roll call vote. [roll call vote] so that's 5 ayes and item eight is approved. >> item 9, approving the operating assistance proposal

dated june 24, 2011 and in implementing agency resolution of project compliance for the amount of $3,950,426. >> good morning, directors. this is a routine funding resolution and required board resolution. this is the annual allocation of operating dollars. per legislation, it now comes to tjpa for temporary operations. this is just a routine request for the $3.9 million for operating funds. vice chair ortiz: thank you. is the motion? a second? director metcalf: second. vice chair ortiz: roll call
