PROJECT DEMONSTRATES SEVERAL CLASSICAL ADVANTAGES OF HELICAL PILES SPEED: Total foundaon install me was 4 days. Day 1: Survey in pile loca- ons and install baer boards. Day 2: Hydro excavate to look for under- ground obstrucons. Day 3: Install helical piles. Day 4: Poured concrete to fill in hydro excavated holes. UNINTRUSIVE: Small equipment and crew were able to stay out of truck lanes. No excavaon for foundaons. No need to reroute exisng lines or conduit. No soil spoils requiring disposal. Unaffected by weather: Hydro-excavaon occurred during heavy rains. Helical piles installed the next day in wet condions. Immediate load bearing capability: Canopy base plates were aached di- rectly to the pile cap. Cost Savings: Helical piles not only met the schedule and access require- ments; they were much cheaper than spread footers. CANOPY Customer needed a new can- opy over an exisng truck unloading rack. Operaon needed to connue as unin- terrupted as possible. Above picture taken four weeks aſter project was started. Includes paving and installa- on of lights. Truck unload- ing was never stopped or di- verted. SPREAD FOOTER OPTION Spread footers were esmat- ed to take at least 3 1/2 weeks to install. Truck lanes would have to be closed while footers were dug, formed, poured, and allowed to cure. Helical Pile Case Study Canopy over Truck Unloading Rack Cheaper, Faster, and more Flexible than Spread footers
