m2017/ The Rocky Pen Run Reservoir dam excavation and foundation preparation project was one
phase of a multi-phase construction project that created additional drinking water reserves for
Stafford County, Virginia. The Rocky Pen Run Reservoir is located approximately one mile
upstream of the convergence of Rocky Pen Run with the Rappahannock River.
The scope of work for this phase included clearing 28 acres of land, the construction of a
reinforced concrete pipe (RCP) diversion to temporarily reroute Rocky Pen Run around the future
dam location, providing a suitable foundation for the new earthen dam, excavation to rock, and
foundation cleaning.
Upon completion of the work, a dispute arose between the General Contractor and its specialty
subsurface drilling and grouting sub-contractor relating to delay and disruption costs incurred by
the subcontractor. The consultant performed various cost, schedule, and lost productivity
analyses (measured mile and earned value) to determine what went wrong, why, and who was
responsible for the time and cost overruns – the rest of the story!

• 28 acres of clearing and grubbing;
• 704 linear feet (LF) of 84 inch reinforced concrete pipe (RCP) stream diversion;
• 44,500 LF of subsurface drilling and grouting to provide a suitable foundation for the new earthen dam;
• Excavation to rock, foundation cleaning, removal of rock outcroppings, and various dental concrete procedures;
• 1,135 LF of concrete grout cap along the centerline of the future dam.

foundation for the new earthen dam, including drilling
of approximately 44,500 LF grouting of the existing
strata.
• The majority of this work was performed from the new
concrete grout cap.

Lost Productivity Analysis
• O’C&L performed a lost productivity analysis using the “Measured Mile” Approach
– Definition: compares the contractor's activities
during the impacted period of performance with
the contractor's identical or substantially similar
activities during a period of unimpacted
performance (Measured Mile Period).

Modification to Measured Mile Approach
• Even the Measured Mile period was impacted by delay,
disruption and lack of adequate access.
– Layne could have achieved a higher level of production during this period but
for GEI’s failure to provide 75% of the work areas to Layne in accordance
with its subcontract agreement. Instead, Layne was forced to “leapfrog” and
perform work out of sequence.
• O’C&L conservatively modified the Measured Mile production
rate by 10% to account for the impact of leapfrogging and the
performance of work out-of-sequence during this period. This
adjustment resulted in a revised Measured Mile production rate
of 395.17 LF/DY (359.24 * 1.10).

• Layne was provided limited access to its work contrary to the provisions of its subcontract agreement.
• Inadequate access to its work, delay to predecessor work and other disruptions to its work negatively and measurably impacted Layne's productivity.
• O’C&L concluded that Layne is entitled to at least $813,557.81 for delays and inefficiencies.
• O’C&L presented its analysis at Mediation and the case successfully settled.
