Quarry-to-Park Project Shows Cost Control Success for Construction Teams

According to ENR, Portland’s Parklane Park project demonstrates how early contractor involvement can dramatically reduce costs on complex site development projects. The 25-acre recreational facility, built on a former quarry site, saw its budget balloon from $8 million to nearly $30 million at the 30% design stage before construction manager Stacy Witbeck worked with Portland Parks & Recreation and designer Walker Macy to cut $10 million through value engineering over three years of preconstruction planning.

The project transformed challenging terrain that was “underwater around three months of the year” into a comprehensive park with soccer fields, courts, playgrounds, and community facilities. Key cost reductions came from material substitutions, such as replacing concrete paths with asphalt or gravel alternatives.

What It Means for Subcontractors

• Site preparation and earthwork contractors can expect more quarry and brownfield redevelopment projects as cities repurpose industrial land for public use
• Early involvement in preconstruction becomes more valuable as owners seek cost control through contractor expertise before designs are finalized
• Flexible material approaches create opportunities for subcontractors who can offer cost-effective alternatives to traditional specifications without compromising functionality
