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.

• Bidding took place September - October, 2009

• Layne was one of 5 subcontractors that bid• Bid was 1% below second bidder• Bid was based on, and its subcontract

required:– At least 75% of the production work area was

to be available prior to the start of work.

• Layne’s productivity was impacted by:

– Restricted access to production work;

– Stacking of trades (General Contractor and concrete

subcontractor);

– Unfavorable winter conditions;

– Scope changes.

• Layne's work was planned and its bid based on its

ability to work efficiently. In-part, this required that

Layne be provided 75% of the production work area

at the beginning of its operation.

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).
