Update 13

Acaccelerated Bridge Construction

The steel bridge competition consists of three scored sections. These sections include weight, deflection, and construction time. With fabrication completed, the weight and deflection portions of the bridge are mostly set in stone. The final variable score is the time of construction on site during the regional competition at NJIT. To ensure a quick build time ABC (Accelerated Bridge Construction) techniques were implemented. The major techniques that were implemented included using multiple piers, consistent building steps, and assemblies. Multiple piers allow for the bridge to be supported without a team member needing to hold it. This results in more efficient construction as team members can constantly be moving and building. Consistent building steps result in a methodical and repeated process of building the bridge efficiently and without delay. The final technique was using assemblies. Assemblies are two members that are connected in the construction zone and then moved by two members into position on the bridge. These are beneficial because they allowed the team to span the river and not have to connect the upper and lower sections once in place. Overall these methods have allowed for extremely quick build times that will make the team competitive at the competition.

Bridge Transportation

With the fabrication and aesthetic components of the bridge complete, the next major concern was the transportation of the bridge. Given that our competition will be conducted at NJIT, it is necessary to develop a method for moving the bridge to the competition site. Along with the physical members of the bridge, numerous other items must be transported. These items include our piers, safety helmets, construction tools, tool belts, and other miscellaneous items. Using readily available materials, the team decided to construct a box with wheels that would be able to hold all of the listed items. A second level made out of plywood and 2×4 boards was used to split the container in half to increase its organization and capacity. Additionally, screws/holes were put into the walls of the box in order to organize each of our tools. The final step was to put rails through the box so that it could be lifted in to the back of our school van on competition day. The previous years name plate was also mounted to the side of the box which is a tradition we hope to continue.
