The Blewett Falls project, located on the Pee Dee River near Rockingham, has two earth embankments totaling 1,700 feet long, a 1,468-foot-long concrete ogee spillway, and a 300-foot-long powerhouse intake dam with a maximum concrete structure height of 47 feet. The dam impounds a reservoir with 2,560 acres at normal pool and an installed capacity of 25 megawatts. Services have included:

• Overturning and sliding stability analyses using the cracked-base method of analysis at the intake dam, powerhouse, and spillway dam; report of findings submitted to the FERC.
• Stability analysis of the intake and spillway dams and powerhouse using earthquake loading conditions.
• Draft tube inspection of all six powerhouse units; detailed evaluation of cracking and deterioration and design for remedial repairs, including adding stiffener rings to draft tube liner and steel plates to replace significant beam support section loss.
• Detailed inspection of eight steel penstocks, including ultrasonic thickness testing, metallurgical laboratory testing of coupon samples for material properties, and structural analysis based on testing results.
• Design, plans, and specifications for relocation of plant cooling water intake and modifications to piping system.
• Supervision of underwater inspection of timber headgates and steel supports.
• Supervision of soundings to obtain silt line for comparison to previous data to evaluate silt accumulation.
• Direction of all underwater inspections of the spillway approach training walls and publication of a report documenting findings.
• Detailed structural condition survey of 1,468-foot-long spillway ogee surface and documentation of cracking and deterioration, including an underwater inspection and soundings along the spillway toe and a report documenting survey findings.
• Design plans and specifications to enhance fishing access to the powerhouse tailrace, including construction of a handicapped-accessible, 300-foot-long walkway and fishing dock across the full width of the downstream face of the powerhouse directly above tailrace.
