commissioner borden: i have a question about excavation. the planner mentioned the bustling would be closed on kerry during the excavation period -- closed on geary during the excavation period as lisagor closures. how long? >> i do not exactly how long the closure of the geary transit lane would be. i do not know it the construction has developed that level of detail yet. i would imagine a leak during the excavation phase, the first year or two years. not the entire sequencing period. muni would have to operate in a mixed lane, so it will cause some delay for muni and traffic on geary. but it is a temporary situation. the point would be during the detailed construction planning to minimize the transit lane closure. commissioner borden: you're saying it will be like a year? >> i do not know of the top of my head. commissioner borden: i am just curious. do we have a signal prioritization for muni already along the geary corridor? >> mta is looking for a signal prioritization and priority city-wide. i am guessing that would be coordinated as

here, a team of archaeologists is excavating an abandoned anasazi settlement. woman: the bubble in the center. about 500 people once lived here in more than 400 rooms. the rooms are grouped around circular chambers, called kivas, where the anasazi practiced rituals. the rituals were secret, so the kivas were built below ground level and concealed beneath an earthen roof. heavy beams, like this one, supported the roof. curiously, many beams are charred. the kivas had been burned. archaeologist william lipe. i'm not sure what it means, but i can speculate that the burning of the kiva roofs was some type of closing down ritual for this village. we've seen that a few other places in the northern southwest at a time when there was a substantial movement of population out of an area. so i think that's a possibility -- that they burned, intentionally burned, the kivas when they left this area for good. keach: to find out when the site was abandoned, a charred roof beam is wrapped and sent to a laboratory. the anasazi often moved their villages, but usually only for a

we assumed all of the shallow soil at pier 70 would have to be excavated and hauled off by truck to an apartment and fill. the fifth alternative is hot spot removals. excavations of areas where the contamination is concentrated and can be identified is different and more severe than the soil around it. so we evaluated each of those alternatives. nine of federally specified a valuation criteria, and six state-specified criteria, and also, using a fairly recently issued guidance document from the state department of toxic substance control that enables a quality of valuation of how different remedial alternatives themselves and have the environment. it looks at the sustainability of the remedial action, how much energy it would use, with the greenhouse gas emissions would be from their remedial action community impacts like traffic and noise. so we ran the short list of feasible alternatives through this, of the evaluation criteria, and with the exception of the no action alternative, all of them were determined to be feasible and at least a good short-term and long-term effectiveness

we will be excavating 2.7 feet throughout the area. over 60% will be in this range of 5 feet to 7 feet below grade. if you walk up from third street to second street, you will notice is quite a climb. the third component, the construction documents. we will be improving the structural mitigation. we saw that we take away from the sites. we will be able to forecast a thicker slab, perhaps tie downs. we looked into the sb percentages. we have over 30% spe. the original award was 7%. director kim: from 7% to what? >> 30%. we get them updated monthly. 9 of them are spe certified. with that, i will be happy to answer any questions. >> are there any questions? director harbor? -- harper? director harper: it looks like we are at 90% construction costs for design and engineering? >> that is right. >> that seems high to me. is there something that makes it extraordinarily hide? >> the extraordinarily high is the additional structural analysis that has to be performed underneath the west approach. our initial assumption, and the initial amendmen

mexican archaeologist angel garcia cook, excavated the cave with macneish. cook is now director of the mexican institute of archaeology. yeah, que bueno, yes, el tipo flaco. flaco. keach: this projectile point indicates that this cave was occupied at the same time as purron cave, about 5000 b.c. clues to the diet of the cave's ancient residents also began turning up. interpreter: this is a piece of maguey that was cooked over a fire and then chewed. it was a species of cactus that they chewed and then spat out. sometimes you can see the mark of people's teeth on these quids. so maguey was clearly a part of the diet of the people that came here at a certain season of the year. this is a leaf of nopal cactus, which you can find during all the seasons, but there are times when people eat it more often because there is nothing else to eat. keach: nopal still grows just outside the cave. macneish's workmen remember droughts when they ate nopal to stave off hunger and thirst. they call the cactus "starvation food." so, discovering cactus in the cave tells the arch

we've not excavated any of the remains. we don't feel that's an appropriate aspect of our archaeological program, but we have done enough work to understand the full extent that this is the family burial ground. madison's grave is in one side of it. and he was placed here and located so that his wife, dolley, who outlived him, could be buried next to him. however, dolley had moved to washington and died in washington, and she was first interred at congressional cemetery. and it wasn't until the 1850s that her body was returned to montpelier. at about the same time, this memorial was erected, in 1858, and you see it just simply marks madison giving his last name, his birth date, and the date of his death. however, in building this memorial, to mark his burial site, the builders also used the grave site set aside for dolley so that when her remains were brought here about the same time, she was buried behind madison instead of beside him and she also has a marker on her grave site. we think today that a grave has to be marked

just some shots of the excavation. we were able to take a shorter reverse angle on a zone four. there it shows a photo of the site. in the central and west section, the main thing has been getting the trestle bridge ready, starting that cross lot. you can see the right hand in the far corner. you can see the diagonal portion of the cross pop bracing -- across -- cross hop breezing. that is looking the other way. you can see that, the diagonal racing going in. you can also see the completed piles. the side-by-side roads. and of course, the trestle bridge. that is the far southwest end of the project for the trains will, in in the future prevent -- where the trains will come in in the future. as this gets completed a little bit further on the diagonal, they are actually going to start the massive excavation later this week and next week, where we would actually be pulling out the braces and go down to the next level as we crossed the lot and go further to the east. the cdsm wall was completed on first street two weekends before easter. it took a lot more planning because of the ut

it will be excavated underneath van ness avenue. that construction is about a 10- month time span when it they will have to cut open the van ness avenue. only after 7:00 p.m. there will close down two of the six lanes at a time at most. always having four lanes of traffic open. and always having one of the two sidewalks on been a 70 that could be closed. only during that tunnel construction time with any pedestrians be routed onto a different side of history. but there will always be at least one sidewalk lebanon of van ness avenue. that is construction. now i will talk about bus rapid transit. there are, i believe, three alternatives being studied as part of the van ness avenue brt project. one is side-running, and two are center-running. i will first talk about side- running and in the two center- running together. i was going to point out -- the cathedral hill campus -- and van ness avenue north this to the right. south is to the left. this graphic is rotated 90 degrees. the cathedral hill campus site is the second block over to

there is excavation if you come out of the ground level and go up, so it is 3 low profile in to the rear yard. as far as the variances required, i think staff can address the more, but the bottom line is the rear yard and the non compliance. i believe that is it. >> public hearing is closed. commissioners? commissioner moore: i need to put on record set december 8 when this project was before us i asked for a continuance because i found the drawings insufficient. i have about in front of me. they are identical. not one particular comment. not one particular item has been revised. the original drawings were issued on june 27 -- on july 27, 2010. gooare would like to suggest --i would like to suggest the letter speaks to these drawings. i did indicate to staff that if this project comes back again, please make sure the drawings are accurate and understandable. as much as i find the story credible, i believe for this commission to affect them objectively, you out to have a drawing in front of you. i would repeat that again today, and while i am not opposed to the project, i need to understa

all we can do really is the excavation. we were at the stage where there was not a design change that would be possible, but there was a single design change that made it better, less expensive to respond to that, and that's the students moved the unit and turned it 90 degrees. those of you who know the house over on elliot, it was supposed to face the street and be further away from the house next to it, but by moving and rotating it, we minimized the amount of excavation necessary that would send the cost up higher. in the end, it's better that way. that's just my opinion. here's the images. the very tight house. we had square footage guidelines we had to stick to, and it's 900 square feet in the main part of the building, and then because it had to be two story, it's in the historic district, had to be two story, had to have stories, tried to squeeze storage and a powder room in the stair, so it came from the requirement of habitat and additional square footage was allowed to us to get up to the second floor. when you ha

borings that were drilled to various steps throughout the site and from test pits, shallowed of excavations. we collected more than 50 ground water samples from temporary sampling locations, and also from 10 a permanent ground water monitoring wells. we collected 33 soil samples. the reason soil gas is interesting is because soil gas, the air that exist in the spaces within subsurface soil can migrate up through foundations into buildings, and also can migrate into outdoor air. if you of volatile organic compounds in soil gas, those can pose a potential health risk if they migrate into inclosed buildings. that is why we were looking at that. so ho thethis site investigation produced four key findings. it is containing metals, prh's, are particularly problematic class of hydrocarbon, at concentrations exceeding cleanup levels throughout the entire site. those contaminants are from naturally occurring sources such as the serpentine rock that was used to create the land, and also historic industrial operations. those exceeded cleanup levels for all of the three different anticipated future use

we have excavated and found a lot of artifact there is. they met there and stayed there for about a day and a half. now, they still had no clue what happened to santa ana. they had no orders from santa ana, but they had a meeting of the generals on april 25th, 1836, at madam powell's, and what they decided to do was they decided to retreat. they were going to go down to this crossing, which is the one that was used on the way north, and they were going to come down to victoria and they were going to wait for orders from the mexican government. they didn't know what they wanted to do. they were going to get resupplied, they were going to connect with the thousand troops that were still in san antonio. so we got about 4,000 mexican troops still in texas, 2,500 of them are here trying to get to here, and they still have about 1,000 in san antonio, and then, of course, they've got other units spread out at victoria, at goliad. they're all up and down here. they're going to reunite. that's the plan, and they leave the morning of april 26th, oka

the turret came up, excavation continued on the surface. and shortly after that, a second set of remains were found lying just underneath -- oh, what did i just do? oops. there we go. a second set of remains were

and we came out here with archaeologists, excavated the site, did about five years of excavation and other research and decided we had a wonderful opportunity to bring this back and to show what an 18th century whiskey distillery was like. and you can't see it anywhere else in the country. >> and there's a gris mill here, as well? >> the reason the distillery's here is because washington already had a gris mill located here. it was a major part of the plantation made lots of money off of it over the years. and in 1797 at the end of his second term as president, he was getting ready to come back to mt. vernon and hired a scotsman by the name of james anderson to be his plantation manager. and apparently all scotsmen know how to distill, or at least anderson did. and as soon as he was on the job, he lobbied washington and said if you'll pay for this, i can make you a lot of money by distilling whiskey. and washington, you know, initially said, you know, look, i don't know much about that, but we have letters that he wrote to friends of his asking their advice and they said as long as h

a disappearing act that will take 57 hours to complete, 40 excavators, some of which we're passing right now. they're already staged here on the elevated roadway. it'll be up to 300 workers and we imagine probably lots of aspirin for the drivers trying to get in and out of san francisco. it all starts at 8:00 tonight when caltrans will shut down doyle drive, shutting down until 5:00 monday morning, the road will be closed at marina and lombard streets in san francisco. highway 1 and the golden gate bridge will remain open. but caltran is warning of gridlock. avoid this area if you can this weekend. doyle drive is coming down to make way for the new $1.1 billion parkway. it's a partial lip tunnelled approach to the golden gate bridge that is not expected to open until 2016. a much-needed improvement over doyle drive. doyle drive 1/2 mile stretch of elevated roadway that became too old and dangerous. >> doyle drive is from 1936. it's old, it's seismically unsafe, and this has been a project to rebuild it. it's been under construction a little over a year. >> so, again, shutting down at 8:0

wald, -- involved, showing excavation. i am trying to make that point who the sponsors had to you as the members of this commission. i have a right not to have any damages. that's it. thank you. >> thank you. project sponsor, you have a rebuttal, to minutes. -- two minutes./ >> i have an engineering firm as well. nobody has done any work to the foundation. there is no sign of stress, no cracks, the building is completely original on the inside. any sort of settlement in this house, it makes me believe that they are not going to collapse the whole neighborhood. >> we are raised in this house, we just want to live in the house that we grew up then. our parents passed away two and a half years ago. we just want to rebuild. otherwise, we can't afford to. >> we have been in this house, so there has been nothing wrong with the foundation. thank you. >> of the public hearing is closed. commissioner antonini: i think that many of the things that the requests are brought up are probably out of our province and would be covered beca

there was one excavation along the way i remember out in the desert nears winslow, arizona. the desert out there is just a still life with a few landmarks on the horizon and this empty hole, the little colorado river desert, the painted desert, and we were working on a 500-room pueblo dating back to about 1400 ad. i just remember the wind just hailing down on us for days and you would be working down with trowels inside of a trench and if you stop for too long, the sand would start to fill up your hole again because it was blowing so much and everybody was turned away from the wind. so it looked like some kind of religious thing was going on here, all these people bowed to the ground for days and days tinkering with some unimaginable smallness in front of them while the wind just pushed harder and harder, sand blasting across you, filling up all the rooms that you just emptied out as if the desert is rolling back over itself. because even where trails are left, trails disappear out there. nothing stays for too long, even the footprints that last for 7 years eventually disapp

these are the cuniform tablets that were excavated in the late 1880's and early 1890's by the university of pennsylvania. tens of thousands of fragments of cuniform fragments. the story of anana starts in her adolescence. it travels through her journey as a queen and a goddess, and much of her story is devoted to the love, a very passionate love, for dimusi, who is a shepherd who she takes as her husband, lover and king. and this is called the return. a lament was raised in the city. my lady weeps bitterly for her young husband. anana weeps bitterly for her young husband. woe for her husband, woe for her young love, woe for her house, woe for her city. dimusi was taken captive in aruk. he will no longer bathe in aradu. he will no longer treat the mother of anana of his mother.

we are now 50% excavated, the segment between the shaft and the portal, we are holding true through that segment. we are expecting that to happen in june. we are expecting to encounter some pretty challenging ground conditions in that area. stay tuned to what we call squeezing ground. we're hoping to be able to delay it. we are trying to maintain safe working conditions. the show covers, we are monitoring the conditions there. what hundred and 75 feet a day, how wanted to brief you. our team is working very closely ha trying to come up with a recovery schedule. the currently projected delays, i will be meeting with in the executive to make sure that the issue is high on their radar screen. very briefly, i wanted to let you know that we have changed over the management of the construction management bureau. it is now being replaced and is now moving on, replaced with one of our most capable persons on board that has been with us since 1992. i am very pleased with all the work we have accomplished so far together. i wanted to remind you that may 7 is the water for people event and you are
