SAI, a Mead & Hunt Company, also investigated the existing fire hydrants and utility poles within sidewalks that are in conflict with the aforementioned design guidelines. In cases of design conflicts, SAI, a Mead & Hunt Company, proposed alternatives, such as providing bump-outs to avoid relocating fire hydrants and utility poles. Such recommendations were summarized by preparing ADA waiver applications that were submitted to MDSHA for review and approval. SAI, a Mead & Hunt Company, was also responsible for:


  • Roadway construction bid documents for milling and resurfacing
