FRONT STREET SHIPYARD
- Project Location: Belfast, ME
- Services Provided:
- Geotechnical consulting for the construction and renovation of a new shipyard facility within the former Stinson Cannery site.
- Investigated subsurface conditions by using test pits, test borings, and seismic cone penetration testing (SCPTµ).
- Field and analytical laboratory testing included corrosion analysis for foundations, Wenner 4 pin field resistivity testing, and field soil screening for pH/redox potential.
- Project Summary:
- New shipyard is a working marina with docking, storage, repairs, and new boat construction capabilities, including a pile/pier supported waterfront travel lift for portable boat cranes (440 tons), a heavy-duty aggregate travel area to support the cranes, renovations to existing buildings, and two new metal buildings – Building #5 and Building #6.
- Building #5 is 22,200 ft2 with a height of 55 feet; Building #6 is 26,800 ft2 with a height of 69 feet; both buildings have overhead cranes for boat fabrication/repair for large boats over 100 feet in length.
- Project Challenges / Innovation:
- Soft marine deposits, contaminated soils, and miscellaneous fill.
- To address these site conditions and constraints, an innovative heavy-duty aggregate section reinforced with geotextiles was designed for the travel cranes and reinforced mat foundations were used to minimize building settlement.
