Email Blog Post

Trial post via email. Going to see if attached image will show up in blog.


This was my first attempt at mobile blogging. I just composed the two sentence fragments above, attached a photo and sent it to my blog. Then it appeared in the format above. It seems good for short and quick entries. If more photos were attached they would all be grouped on the top of the post. But, that is where editing can come in. If nothing else I have found a way to cut the post time down by a bit. The photo is of me (small blue object on the right) next to a massive mining dump truck out in Arizona.

Site Planning & Visualization

For a final project in school we are asked to develop the production plan for the excavation, substructure, superstructure, and masonry and stonework for a proposed addition to our school. Over the course of the semester we had developed these plans individually and for the final project we were asked to combine them. In doing so I decided to use Google SketchUp to visualize the site utilization.


The first image is a view of at the end of the excavation phase. At this point the perimeter fence has been established and the loader and haul trucks are shown in position.

The second image is a view of the caisson installation. Starting at the west the caisson installation will proceed eastward. Then the area to the south will be completed and finally the corner that connects the two. Then grade beams will be formed and poured (this portion was not included in the scope of work, but was included in the model).

The Third image shows the crane location. At this point trailers and restroom facilities have been established on site. The tower crane was selected for its ability to access all parts of the site from one location. Space on the site is limited, so the tower crane helps to alleviate safety hazards and crane relocation issues.

The fourth image is a visualization of the scaffolding from the perpective of a worker on the south side of the building.

This was one of the best benefits of using the SketchUp model It not only allowed a 360-degree 3D view of the site, it also allowed me to see worker perspectives. In a couple of seconds I was able to see what it would be like for a crane operator about to pic a column, stoneworker on scaffolding, and a construction manager or field engineer stepping out of the trailer to see work in progress on the south side of the building (Fifth image).

SketchUp is not a parametric program, it cannot take schedules in to account. But as a free program, it could be used for visualization, and if the proper process was created, I think it could be used for low-level construction animation. The level of detail in the rendering is high, the Google Warehouse has a lot of construction equipment that cuts down on modeling time, and there is the potential to bring models from SketchUp into NavisWorks however, as a zero- or low-cost option, it could prove very helpful in communication with trades.
The Google SketchUp site has a couple of Construction Case Studies showing how professional construction companies use sketchUp for site visualization and safety.

Below is a small video of another project for school in which we were able to bring the SketchUp Model into NavisWorks and automatically synch up the MS Project schedule to it.

Thermography

10:00 pm
78 degrees
Partly cloudy

I've borrowed a thermal imaging camera from the department. The assignment I have is to learn how to use, what problems arise, and how to better use it in the future. I went out this evening and took some images of the townhouse I live in, then I threw them all into Picasa, then into PhotoSynth to try and stitch them all together and see if you could get a low-cost 3D thermal image.

This is what I got. 8% synth on 80 plus images. I think I have to take two or three times as many in order to get them to synth properly.

What I learned or what I got to see visually was:
1. Brick retained much more heat than the aluminum siding above
2. Bushes, trees, and foliage are cooler, and obstruct readings
3. The outside edge of a facade can be cooler than the interior surface (so there is not an even distribution of heat across a surface).
4. Windows require several images to capture what is really happening
5. Dryer and vent projections require several images in order to capture what is really happening

For instance. Here (above image) is a shot of a dryer vent (shown in the center) from about 20 feet away.
Here (above image) is that same dryer vent from below. You can see that there is a 3.9 degree difference in the readings. Also there seems to be considerable leakage in this area (shown in yellow in both) however, this could be an effect of the outdoor light which was on (first image, lower righthand corner).

Another interesting find was on the indoor imaging. When I shot the west wall I saw that the location of the studs and where the ceiling meets the wall was around 80 degrees, the surface of the wall between the studs was around 78, and the actual joint where ceiling meets wall was above 82.5 degrees. So in a small area there is a 4 degree difference. Albeit not very much, but I am measuring in the spring when the weather is much warmer. So with the rest of the time I have this camera I am going to try a couple of more times to get enough thermal scans to get an image into photosynth.

Frontier Culture Museum

Saturday, April 4th
Windy & Clear

ROAD TRIP. No better way to clear the mind than with a roadtrip. Saturday was spent driving up to the Frontier Culture Museum along I-81, in Staunton, VA. The museum is collection of frontier housing types which demonstrate living and working conditions from the 17th to 19th century. There is an English style cottage from the 1600s, some Irish dwellings from the 1700s, a german farmhouse and barns also from the 1700s. On the other side of the property one can find the American frontier houses from the late 1600s to the middle of the 1800s.

The best part of the trip was seeing the construction of these buildings. The English, and German, and American homes were heavy timber structures. The Irish cottages were stone with some timber framing for the roof.


English cottage (c.1630)

American Farm House (c.1840)


Log Cabin (c.2009)
This is a side view of the log cabin. Interestingly enough the log cabin was brought over by Swedish settlers to Delaware. The employees of the FCM work to show the authenticity of the period. On the way out we watched as one guy split a log for fence rails. While he was quatering the log he asked me if I would like to give it a try.

After finding a crack in the wood he drove some iron wedges in with a small hammer. Then he used a mallet made from a tree stump and branch to start splitting. I got to finish off the last half of it. The picture does not capture the weight of that mallet or the sound. The log made this incredible ripping noise as it was being separated.

When it was all said and done we had had a great day and learned a lot about early frontier archicture and construction.

As a side project: I want to start a side project of trying to find a way to introduce a colonial period kitchen into a modern day kitchen. The kitchens in these buildings were about 10 feet wide and the floor of the room was the hearth. What would it be like to be in a modern day kitchen and able to cook on a stove top as well as bake bread in a brick oven? Something to think about at least.

NYC Shadow Experience

On Monday March 9th and Tuesday March 10th I followed the Senior Project Manager for a major construction company around to learn about leadership in the construction industry. I will not include the names of the owner or construction company involved.


A view of the Construction at the World Trade Center, as seen from the 8th floor future greenroof. The project is a 45 story, 720 foot tall high-rise. As of Tuesday the building is at approximately 90% completion and the curtain wall is installed up to the 38th floor. The project is aiming for a LEED Gold rating for Core & Shell.


View looking upward on Vessey Street


View of two water tanks on rooftop. These tanks provide additional water pressure for the plumbing and fire suppression systems. They are found on almost every building in New York City and are made by only one company in Queens, New York.

View of the monorail system.
The monorail system wraps the perimeter of the building. Curtain wall picks are made from one location, hoisted, then moved along the monorail and dropped into place.

A couple of things I learned from the PM:
1. Get to work when the workers do
2. Demand a high level of quality
3. Understand what the subs need to be profitable and try to give it to them
4. Understand the work process down to the smallest detail
5. Learn from mistakes (Your own, the company's, or colleagues)

Finally, on the conference room wall at the field office, the PM wrote a list of things to do in order to be an effective member of the company:
Search for answers yourself
Speak up when you fall short

Ask someone who knows what they are talking about

Alban CAT

03/07/09 - ALBAN CAT dealership on I-81

On a recent drive up I-81 I came across the ALBAN CAT Rental facility (http://www.albancat.com/home/). I drove up to the showroom and asked to walk around the yard. I was able to take some photos of equipment which was either available for rental, awaiting or finishing servicing. I had been learning a little about each machine over the previous weeks and to finally be able to approach the machine to get a close look was very thrilling. So thrilling it was the only other stop I made, aside for gas, on the 500 mile trip to New York.

1,612 View

1,612 - the number of view of my first video post to YouTube just four months ago.
Of those 1,612 views, almost half have been from YouTube searches, just about 22% have been from related videos which YouTube links to, and 21% of the views have been from embedded players (like this blog and another one that seems to be popular (http://www.breezybreak.com).

I've only received one comment on the video -- "Now thats a fine bit of kit" -- from a user in the UK. People in countries around the world have seen this video (even someone in Mongolia) and I can't help but wonder if this is having an impact on construction somewhere else. Has someone seen this and changed the way they install metal track...increasing productivity? I have had no other feedback yet, but am hopeful.

I still think the blog can be a good Knowledge Management (KM) tool. I just have to resolve the technology with the process. It was easy enough to instruct a class of 40+ students to create their own blogs, it is less clear how to develop exercises to get them to exceed the minimum standards for lesson objectives.
