UAS FH Construction Update for 11/27/2013
Here are just a few things we are thankful for on the UAS Freshman Housing construction site.
Being “Out of the Ground” before the first snow fall.
Insulated Carhartt’s that make it bearable to work outside in the winter.
Man –Lifts that keep us from having to walk around 30 feet in the air on a 6 inch wide metal beam.
Thanksgiving Day that gives us an day off the job site to be with friends and family before going back to work on Friday.

One Man’s Trash is Another Man’s Treasure
Thursday we got more than a foot and half of powdery snow at the construction site. I saw this as a Treasure of photo opportunities to capture a fresh white blanket covering our campus. Below I have shared with you just a couple of these Treasured photos.
The Contractor was less enthused than I was about our blanket of snow. He saw this as a big blanket of Trash that was getting in the way of building the Freshman Residence Hall. The snow covered up all of the identification numbers on the red iron, so each piece of red iron had to be brushed off before he could tell what piece of iron could be installed nest. This week they have installed a large portion of the red iron that makes up the commons area. The snow made mess for the mechanical contractor that they had to brush, shovel and haul it away before they could continue to install water and wastewater piping. The snow on top of the metal pan deck of Residence Hall #2 made it so slippery up there that workers had to shuffle or crawl around just to keep from falling down.
Even though the Contractor saw the snow as Trash that had to be moved and I saw the snow as a Treasure of photo opportunities, I think we both agreed that we can hardly wait for the weekend to go skiing, snow shoeing and sledding.

The Contractor erected the red-iron (steel) that encloses the elevator. This gives you an idea how tall the Freshman Residence Housing project will be.
Watch the construction site over the next couple of weeks and you will see more red iron going up, building the commons area.
What an awesome day it is out there!

Before & After
The Contractors work this week gives us some nice Before / After photos. Last Friday the Contractor had the big blue concrete pump truck on site pouring the ground floor concrete slab for Freshman Resident Housing Hall I. On Saturday, they poured the floor slab for the commons area and last Wednesday they framed up the first wall in Freshman Resident Housing Hall II. This week the framers finished the first floor walls in Hall I, the exterior walls in Hall II and will complete all the interior walls by tomorrow. The mechanical contractor is following close behind the framers installing piping. The Contractor is getting more workers on site each day and the work is progressing nicely.
I always get a kick out of Before / After photos. Whether it is looking at high school yearbooks, driver’s license photos or family photo albums, I find it interesting to see how we have changed over the years.
Puff ball clouds in the sky, snow on the mountains, fog on the lake, sun in the trees, frost on the ground and orange vests in the construction zone. What a fantastic view the construction crew has today.
Last weekend the crew had to do some night work and they said there was an excellent display of northern lights. Checking out UAF’s Aurora’s forecast, it looks like we may see some northern lights tonight.

We Have Walls!
The first wall went up on the Freshman Residence Housing project on Wednesday; only 399 more to go. This is the stage of construction that you can visually see lots of progress. On Saturday they poured the concrete floor slab on Residence Hall II. Walking by the site it was hard to notice all of the work over the past several weeks that went into getting that concrete slab ready and constructed. Then between Wednesday morning and Thursday afternoon, the walls for Residence Hall II were put up and you could not but notice how the walls just seemed to jump out of the ground.
So it is with many of our tasks in life. Some tasks are easily noticeable and it’s easy to see your accomplishments. Then there are some tasks that take a lot of work and are hardly ever noticed. But, remember that those shiny steel walls that everyone can see, could not have gone up if it were not for the crushed rock foundation that no one will see.

You will love Mechanical Engineers for this one.
In the old days, Mechanical Engineers heated buildings with a fireplace or pot-bellied stove and they cooled buildings by opening the window. Now days they use sophisticated HVAC (Heating & Ventilation & Air-Conditioning) equipment. It does not matter if it’s minus 20 degrees outside or 95 degrees and 100 percent humidity, you can walk in most modern buildings and the HVAC system will keep you at a comfortable 68-72 degrees.
The Mechanical Engineers for the UAS Freshman Residence Hall already provided us with those cool blue pipes to provide fresh air to keep your room smelling clean. (See October 11 update) But, now you will love the Mechanical Engineers for heating the UAS Freshman Residence Hall with radiant floor heating. Radiant floor heating works by pumping hot water through the white pipes shown in the photos and which will soon be embedded in a concrete floor. The concrete floor heats up and keeps the whole building warm. No longer will you have to put your fuzzy slippers on before jumping out of bed in the morning to keep your feet from freezing, the heated floor will keep your feet nice and toasty warm. As anyone who has experienced radiant floor heating, can attest that it is one of the best ideas Mechanical Engineers have come up with in the past 20 years. So get rid of those fuzzy slippers and say thank you to a Mechanical Engineer.

Take a close look at this concrete; it looks like it is trying to grow fur.
I know winter is coming, but isn’t this going too far?
Concrete is very strong in compression, typically reaching 4,000 pounds per square inch (PSI). However, concrete is weak in tension, typically 400 PSI. For example a concrete cylinder the size of your coffee mug could hold school bus on top of it without cracking. However, if you were to place this same concrete cylinder in tension by hanging from it, you could barely suspend a Smart Car. This is why we place steel inside structural concrete. The concrete handles the compressive pressures while the steel handles the tension stresses.
Our fury concrete is called Fiber-Reinforced Concrete (FRC). These fibers are made from many different materials; steel, glass, nylon, polypropylene and cellulose. The Contractor has used polypropylene fibers in the concrete for the curb/gutter out in front of the new UAS Freshman Residence Hall. These fibers eliminate the need to place steel in the curb /gutter and it also makes the concrete more durable, especially when exposed to freezing /thawing cycles.
Fiber-reinforced concrete is much like our community. Some of us are good under compression, some are good under tension, some are good at math, some are good at biology and some are good at art. When we are all mixed together in a community, we strengthen each other and accomplish much greater things, than if we tried to stand all alone.
Yesterday was a rough day for DOT&PF's Roundabout with traffic backed up on all three sides for what seemed like miles. Today is much better with two narrow lanes of traffic open. In the next couple of days, the Capitol Transit bus stop and shelter will be moved from its current location near the Glacier Highway intersection, up the hill next to the bus barn.
The Contractor is still hopping to be able to pave Back Loop from the UAS intersection down to Caroline Street late this week or early next week. However, they still have a lot of work to complete before then.

Big Blue Truck Back:
This week the Contractor brought the Big Blue Concrete pump truck back on site to pour several of the interior foundations for Residence Hall I. This week’s photo shows that this concrete truck can reach out there 100 feet! Did your math teacher ever explain how a lever works? See the attached sketch. It is a direct relation of weight times length, (W)(L)=F. So for our example, we have a lever that is 10 feet long with a 10 lb. weight. This lever could lift a 100 lb. weight that is 1 foot from the fulcrum. So if you ever decide to become a concrete pump truck designer, you will use this calculation to figure out how heavy your truck needs to be so your concrete boom can reach out 100 feet, without your truck tipping over.
Other accomplishments this week included reclaiming the sewerline access path from the residence Hall down the hill to Glacier Highway and getting the waterline all the way inside the building. The underground work is wrapping up quickly, which is good because the snow is creeping down the mountains.

Big Blue Pipe:
The Contractor has been busy this week with more than 20 workers on site some days. The carpenters poured several more foundations for the commons area between the two Residence Halls. Alaska Electric Light and Power (AEL&P) was on site early in the week and placed underground power lines up to about the Noyse Pavilion. The site work crew completed the sewer line and started reclaiming the large cut through the trees so it will quickly grow back with native vegetation. However, it was the mechanical contractor who brought the most color to the construction site this week with their installation of several Big Blue Pipes. These pipes are air ducts that will be used circulate air thought the building. Without the proper ventilation, the building would feel stuffy and here in Southeast Alaska be a haven for mold growth.
All of the Big Blue Pipes you see in these photos will be covered in soil and buried, as they lie beneath the first floor. If you want to know more about this Big Blue Pipe you can look at the manufacturers’ website at http://www.blueduct.com/
