Right now, your project would have to be considered a disaster. I could have walked from the fire station to Abernathy faster that was able to drive. Yet once past Abernathy, I was able to drive between 40 and 50 mph. There is a major flaw in your design that I can't believe. Just before Johnson's Ferry hits Abernathy coming from Sandy Springs, the road used to expand into two outbound lanes. That allowed you to queue up twice the number of cars waiting for the next green light. When that light turned green, those cars were able to take off in a straight line, rather than having to make a left turn. In other words, your new intersection is about 40% as efficient for all those commuters coming down Johnson's Ferry. If this abysmal design is not fixed, you will see accidents and potentially violent behavior at Sandy Springs Circle and and Johnson's Ferry road. Commuters will be furious if today's experience is truly representative of what you have created. I mean tar and feather, fire someone furious. I hope there is better to come. If not, someone in your office should experience career consequences for such an obviously horrible design. Regards,

 Contractor is not a designer  Understanding Design Intentions  Adversarial Relationships  How do we resolve problems?  Time to review and absorb plans  Building survey files  Resolve discovered omissions/errors or correct the contractor  Begin construction  Stake the project and absorb the stakes  Resolve omissions/errors discovered in the field (for the life of the project) o The superiority of the three dimensional field

 Survey is the key  Attention to detail  Incorporate knowledge from past mistakes  Neat and visible  Willingness to listen and help  No designer is perfect – no contractor is perfect  Compliment of views  Give and take (Total cooperation from owner/designer/contractor)
