In this project I had to observe constraints on a local construction project.

The site that was visited was the Twin Rivers Dr. demolition and rebuild. This
site is located on Twin Rivers Dr. south of Goodale Blvd. and north of the 850 Twin
Rivers Dr. post office. The original road had ten foot wide lanes, curb no gutter, and a
storm line. The new site will replace the original while adding an under-drain.
There are many issues and constraints that this site faces. Some of the issues and
constraints that this site faces are space, time, and safety. There is not a lot of space for
parking and staging. The only space for this is a 100 foot by 75 foot parking lot. This
creates problems for storage of equipment, pipe, under- drain, dirt, and stone. Another
problem this creates is timing for dump trucks bringing in stone and asphalt, because
there is nowhere for them to wait with their load. They have to be ready for the load right
when the trucks arrive. To fix this there has to be good communication between the
person in charge of the site and the scheduler. Good communication will allow for
material and trucks to arrive only when they need them.
Time is another issue with the site because there is heavy traffic on this road from
the local businesses. Twin Rivers Dr. is the only reasonable way to get on 315 North
from Dublin Rd. With time being a big factor in this construction it is important that the

2. work be done as smoothly as possible. This means that work cannot stop on waiting for
material or labor. A detailed current schedule must be maintained for the project to end
on time. With this road being critical for traffic the work has to be done in segments to
allow for traffic to flow. The north bound side of the road must be done first and then the
south bound side of the road. This adds extra complication to the schedule, because all
the steps of construction have to be done twice. Learning from the north bound side of
the road will help create a better schedule for the south bound side of the road.
Safety is another important issue with the site. When the working area is so
narrow with traffic being inches away there could be a risk of a driver crashing into the
site or the equipment hitting a driver. The traffic control requires leaving a ten foot lane
for traffic which is hard to maintain at the site. If the ten foot lane is not given to the
drivers it will lead to a serious injury. Another safety hazard is when dump trucks come
onto the site, because every time there needs to be a drop off the whole road needs to be
shut down. To make sure there are no safety problems a ten foot lane has to be
maintained for traffic and the scheduler needs to make sure there are enough laborers to
flag traffic when there are dump trucks on site.
Good communication between the scheduler and the person in charge in the field
will fix the issues and constraints of safety, time, and space in this project.
