my name's randy collins, a structural engineer under contract with shane bush since about february. quite frankly, this is a complicated project. but we've been doing project like this in san francisco since the 1920's. so that's why structural engineers are here, that's why geotechnical engineers are here, that's why we're working with a contractor that's been around for 25 years. the procedure we're using here is very well established in san francisco. the shoring and the methodologies that we're using to construct this is very tedious and very time-consuming because we're only going to excavate four feet at a time. and then construct temporary construction, temporary structures to completely brace four feet at a time, and then another four feet, another four feet. once that temporary structure, which is completely designed for all permanent load cases, once that temporary structure is built, we're then going to build anywhere from 12 inch thick to 18 inch thick concrete walls, ceilings, and foundations, to support the final building condition. so i've written a letter that addres

as randy collins mentioned if the tube withholds and is electronically monitored from a hose to a truck. it's a very sophisticated procedure. and it's going to be very successful project. there are other houses where they initially built the garages back where they have elevators so it's very steep, somebody comes home late at night, they have to go in the garage, and go up stairs. they like to have -- above. so if you have any questions about this, i'll be very glad to answer any aspects of this project. i did the project down the street. and i've done grouting projects going back to the hampton hotel at union square since the early 60's. >> without getting into the specifics of the other property, mr. lee i think was the name. >> sorry? >> without getting into the specifics of the other property that you consulted on, the other neighbor, can you give me a general sense of what issues were addressed in order for that project to go through, as it relates to your specialty area. >> well the engineering issues or the political issues? >> engineering issues, please. >> okay. it was a simil
