On-Demand Construction Contracts Keep Costs From Going Through the Roof 

Red roof building

Situation

After 30 years of exposure to the elements, the City of Concord, New Hampshire’s Combined Office and Maintenance Facility — featuring six standing-seam metal-roofed buildings and a metal-roofed fuel dispensary — was in urgent need of major repairs. But the anticipated costs were through the roof.

Roof coating

Solution

Using a competitively awarded Sourcewell IDIQ (indefinite delivery, indefinite quantity) construction contract through Gordian, the city partnered with a local contractor to implement a high-performance silicone roof coating system.

Benefits

  • Silicone roof coating designed specifically for aging metal roofs
  • Long-lasting protection with a 50-year warranty
  • Seamless application process that reduces disruption to operations
  • More cost-effective than a full replacement
  • Proven performance in similar environments over time

IDIQ construction procurement delivers exceptional results

To address the roof repairs without exceeding the budget, Concord selected a local contractor through a Sourcewell-awarded IDIQ construction contract with Gordian. Because these contracts are awarded for an indefinite number of projects, this contractor already had a strong relationship with Concord's General Services Department, which helped accelerate planning and communication.

After being selected for the project, the contractor took the lead in identifying a cost-effective solution for repairing the metal roofs. Initial estimates for a 34,000-square-foot section ranged from $895,000 to $1.7 million, with warranties lasting just 5-15 years. Because these options fell short of the city's goals for cost or durability, the contractor continued searching for alternatives and discovered a silicone roof coating that had performed well on a Boston-area building nearly 20 years earlier. The product’s proven performance led to its selection for Concord’s metal roofs. 

With the right contract, the right partner, and the right solution, Concord turned a challenging project into a long-term win for the community.
