Quick Wastewater Manhole Lowering Engineering Drawing

We are looking for an engineer to create a detailed drawing that will safely lower an existing wastewater manhole in new pavement. The drawing should adhere to US engineering standards and city codes and specifications. The engineer should have experience in wastewater management and be familiar with relevant engineering principles and standards. The drawing must ensure the structural integrity of the manhole while accounting for the new pavement and its load-bearing requirements. The engineer should be able to provide expert guidance and recommendations based on the specific project requirements.
