Load Capacity

Transportation of building materials
02 Aug 2016 - By Mr. Berqstrom

When analysing an existing city and its surroundings, it is natural to look at the infrastructure available, to determine which Solution will be suitable to implement in the future. In my blogpost "Possibilist - A new Breed of Architects & Engineers?" published the 18 Sep 2015 on, I refered to the video by Hans Rosling: Global population growth, box by Box. In this video he shows few different ways of transportation and reflects on how it defines what stage of development a society is in.

I would like to fine-tune this division by looking at capacity load. This is due to my realistic view on transportation of building materials to a building- site. My Load Capacity analysis on the city, based upon Roslings example for transportation, is a simple but rewarding tool, to understand what possible scenarios realisticly can be executed for changing/ upgrading different city- districts.

1. Observ: To start, observ and make note of the main transportation method in the city of examination and gather comparable prices from different providers.
- This outcome is probably the cheapest transport solution in the civilian market, when building according to the regional way of construction. But its not nessesarily the best option for the project. It all depends on level of industrialization on the building site.
- Projects with a low level of industrialization concists mainly of small buildingparts, easy to transport for most vehicles. High level industrialization is showed in projects with complete buildingparts, where the workers tasks on site is assembly, not construction. Robotization will further improve this and replace the worker. 

2. Simulate: To clarify other potential ways for transportation would a simulation of different scenarios assist in the desicionmaking.
- As an example could it, for an highly industrialized project be possible to choose helicopter instead of camel for transporting a lightweight structure. But the camel might be a better and cheaper option when working togheter with the locals on a traditonal building, using buildingmaterial from the surrounding area. Here it is important to remember that lowtech buildings (eg. clay) does not set any limitation for what technological installation is mounted in the building.
- For other, bigger projects might it be interesting to simulate a complete newbuild of roads and infrastructure to reach the building site. Independently to project size, always gather at the end of the simulation- phase an cost overview for the different scenarios at play, for understanding the hard data of cost and time. 

3. Decide: Which direction the project should develop, depends on financial resources and ability to choose the right buildingsystem for the project and site. 

Train, airplanes and boats are not included in the Load Capacity Matrix, since they seldom can influence the transportation of building material all the way to the building- site, even though they might be in the transportation loop (Exceptions to this regularity; airports, trainstations, port or other buildings / structures with immediate distance from the railroad, airstrip or harbor)
