    As concrete cures (hardens) it shrinks for various reasons. In a foundation, the footings are thicker than the slabs and as a result the footings don't move. So as the concrete shrinks the only place for it to move is in the slab because it's thinner (typically four to five inches) resulting in cracks. This is objectionable for many reasons and it is best to keep the cracks to a minimum. The post tension cables are anchored on one edge of the concrete while the other end has a wedge shaped thimble cast into the edge. The cable is in a plastic sheath to keep it from bonding to the concrete. After the concrete has set for a few days they will place a hydraulic jack on the thimble end of the cable and pull it tight. They then force a wedge into the cast in place thimble to grab onto the cable. They then release the cable. They do this twice to get the full benefit of the cable. (if they did it all at once or to soon the concrete would not be strong enough to withstand the force of the cable). The result is that the concrete slab and foundation are pulled together by the tension in the cable. When this happens any cracks that may have developed are pulled together. Imagine a very strong rubber band pulling the concrete together. The result is the cable is in tension and the concrete is in compression with a net result of minimizing cracks that have developed and eliminating any future cracks.

    If you watch it being done, and don't know what they are doing, it is quite perplexing. The number one thing to remember if you are in the area when they are doing this is to not stand in line with the cable. If the cable or the anchor would happen to break, that cable will shoot out of that concrete like a cannon ball. This is one of the main disadvantage of post tension foundations. Imagine a plumber or electrician breaking into the floor to make a future repair and unknowingly cuts one of the cables. It could very well kill them at worse or at best scare the hell out of them.

    I hope this answers your question.

    Students started to move into Huger Hall today. Some were relocating form Harris and Randolph. One girl was not to happy about moving out of Randolph as you could see it on her face.

    They have trimmed and mulched under the oak tress along Tulane Avenue. They look much better. Huger is to the rear. Hamilton is to the right and Tulane Ave. is to the left.

    Rose Garden work continues to progress.

    This is the second building as seen from the east Harris Hall fire escape. University Ave is to the right. They were cleaning off the slab so they could layout the interior walls this morning.

    The second building as seen from the north Harris Hall fire escape. University Ave. is to the rear.

    The second building as seen from the north Harris Hall fire escape. University Ave is to the right. The first building is to the rear.

    Starting to frame the third floor walls of the first Rose Garden building. The yellow wall adjacent to the elevator shaft to the right is a fire wall. University Ave is to the right and Randolph hall is behind the new building.

    The future alley way between the two new rose garden buildings. In a few more weeks we will really start to see what the final product will look like.

    Third floor framing has begun on the first rose garden building. Buchanan Hall is to the rear of the camera, Randolph Hall is to the left. (This is where Huger hall used to be).

    The first concrete block and brick courses on the first building. This has covered the water proofing shown last week. I would guess that the ground level weep holes will be in the next brick course. This should get them above the proposed finished grade around the building. They have sealed the water proofing membrane to the Tyvek building wrap placed around the first floor. Tyvek is the third level of water proofing placed on the building. Tyvek is good stuff, it's kind of like GoreTex for a building. It lets the building ventilate without letting moisture enter.

    rose-9


    They have started to move students out of Buchanan and Harris Halls and they will start the renovation of these buildings soon. I don't know how much longer I will be able to access the Harris Hall fire escape. I might have to pull some strings.

    Does UL expect to make money or just pay for the buildings cost with future dorm income?

    The Baker-Huger complex is finished. All areas are open and the parking lot behind Hamilton Hall is cleaned and being used by faculty and staff of Hamilton Hall. These photos will be the last of the Baker Huger complex I will post unless I see something going on. The area is very nice. When you out of town folks get into town, you should stop by and take a peek, it is really nice. Photographs do not give the scale of what has been done.

    This is the entrance to the Bake Huger Common area from Hamilton Hall. Taft Street is to the far rear of the photo.

    Lots of cut offs at the cutting station. Plenty of saw dust too. they will be here for a while.

    rose-8


    OOPS, somebody hit the corner with a piece of equipment. I guess there might be a brick layer or two hanging around to fix it The plywood with caution tape in the background is protecting Buchanan Hall from the same. It's a pretty tight squeeze between Buchanan and the new building.

    They were really smoking yesterday, Saturday Jan. 21, They started work this morning Suday Jan 22 but apparently a neighbor must have complained about the noise and they were shut down tight as a drum by noon. They started with the renovation work on Harris and Randolph Halls this past week and as a result placed fencing around both buildings. Since they were shut down all the gates were locked and I couldn't get into my usual view points. So some different views this week.

    This is a view of the first building from the corner of Hebrard Blvd and University. They are up to the fourth and final level at this location of the building and started to place roof trusses. Tyvek wrap continues to get higher.

    rose-1


    This is a view from the Student Union Service Drive off of Boucher Street showing building 1 on the left and building 2 on the right. It looks like the combined both crews to concentrate on building 1. They are probably looking to get it out of the weather so they can work through the rest of the winter.

    rose-2

    Building 2 showing not much progress over the last week.

    this commercial construction is a whole different ballgame, I can't imagine the scheduling it takes

    Scheduling in commercial construction is the key. The Framing contractor has the electrical, mechanical and plumbing contractors chasing him with rough in. They in turn have the sheet rock and finishing contractors after them who have the electrical, mechanical and plumbing contractors after them so they can do installs. They in turn have the painting contractor after them so he can finish. It looks like a a bunch of ants crawling all over the place but they eventually get it all done. Along with the general superintendent there are at least 4 or five other guys in the job shack making sure that everybody is doing what they are supposed to do. Every sub contractor has a superintendent that not only makes sure he has enough people on the job but has all the materials he needs and a place to store it. He also needs to make sure that there is equipment and tools on site too. Labor, materials, equipment where and when you need it and the space to work and store "stuff" when you don't.

    A big problem on jobs like this is if a sub shows up early (because he doesn't have anything else to do and he needs to keep his workers busy) or if he is late because he is busy trying to finish another job. Early is bad but late is worse.

    Today I had a call from a contractor on one of my projects needing layout staking for a drainage project so he could work TODAY. It's a good thing he called early this morning and I could reschedule and get it done. It's not that he showed up early it's just that he showed up unexpectedly. It would have been nice if he would have called on Thursday or Friday but that's the way it is.

    Renovation work on Randolph and Harris Hall has started. Randolph Hall is having asbestos removed, they haven't started asbestos removal in Harris Hall yet.

    This is a view from the University Ave Hebrard Blvd intersection. Randolph Hall is to the right and University Ave is to the left. Roof trusses are on this section of the building and the roof is decked as you will see later.

    Three inches of rain on Saturday February 4 put a damper on work this past week but they still have made good progress. It looks like the two Rose Garden buildings will be named Bonin and Corona Halls although I don't know which one is which. Corona Hall is one of the eyesore buildings in the student union complex. I was expecting one of them to be named Evangeline Hall.

    This is Building 1 as seen from the University Ave. Hebrard Blvd intersection. University is to the left and Randolph Hall is to the right.

    Half of the roof is totally shingled and that portion of the building is getting windows installed. Looks like they are really trying to get out of the weather.

    These are the "eyebrow" convection roof air vents. One of the workers at the fab shop wrote "Made in USA" on it. I should have taken a photo of it.

    An inch of rain on Friday February 9 and rain throughout the last week has kept the site pretty muddy but they still continue to make progress.

    A view of Building one from the Hebrard Blvd and East University Intersection. Randolph Hall is to the right. They were setting up scaffolding to proceed with brick work. this building has about 60 percent of the windows installed. Once the roof is finished then the building will be out of the weather and they can really start to get interior work done.

    rose-1

    A view of Building one from the Saucier Clinic steps. (the clinic has moved to the renovated OK Allen Hall). Windows are installed on a portion of this facade and they are moving to the left with window installation.

    rose4

    Building one to the rear getting its roof while a portion of building two in the foreground is at level two with the third floor deck on the way. This is from the north Harris Hall fire escape. I don't think I will be able to see building one from this vantage point much longer.

    rose-8

    Building two as seen from North Harris Hall fire escape. This is where Bonin Hall used to be. The other end of Harris Hall is to the extreme right.

    rose-7

    Building two as seen from Student Union Service drive. The fork lift bringing scaffolds to the front of building one passed through this area and it is so muddy the fork lift is sinking almost to its axles.

    rose-5

    Randolph Hall renovation has begun now that interior Asbestos has been removed. They are removing asbestos from the crawl space now.

    rose-2

    A view of construction from the driveway to my home. It won't be much different then before because the oak tress will hide most of the new buildings.

    rose-6

    They were really getting with it yesterday and today because we are expecting rain almost every day this coming week.
