I designed a 5 timber bridges for a resort developer. The bridges are 2 lane and 60-100ft long with 1 bridge 1300feet long. The bridges are about 4-6 feet high, over wetlands. I designed the bridges with an HS20-44 loading and a crash tested guardrail (as originally requested). The pricing came back about 5 times what they had budgeted and they are asking me to reduce my loading requirements..
I think that I can reduce my loading to a H-20 loading but I am having trouble finding the minimum loading for a bridge over commercial property and what is the minimum requirement for a guardrail. The client is asking me to reduce my guardrail considerably
Before I walk away from this project, I curious to what everyone's opinion is regarding the loading and guardrail requirements.
