5. Drivers for Higher Bid Pricing
• Labor Cost Increases
– Hurricane Harvey projects now bidding
– Impacting jobs in Texas and Oklahoma
– Imported labor required
• Materials Costs
– 2018 Aluminum and Steel Tariffs higher impact than expected
– Higher costs for concrete and steel due to demand
• Non-Competitive Bidding
– Rich marketplace for municipal construction impacted by Harvey projects
– Actively worked to invite contractors to bid
– All indicated competition, other pursuits, and remoteness of BCS market

• Reduced cost approximately $267,500 through work with selected
contractor and engineer
