Ensure the following variables are considered at the outset of each streets project:
Material costs will vary based on local availability, location, and transportation. Modular units installed on site can be more cost effective.
Labor affordability and availability differ greatly across various countries and regions.
Signals and enforcement cameras are prohibitively expensive in some places, and ongoing repair or maintenance costs can see them installed but not used. Reliable sources of energy are not available in all places, and so renewable energy back-up systems are needed, and these may add to the cost.
Design and construction duration can impact the overall cost, influencing labor costs, equipment rental, or lost income for adjacent businesses. Large capital projects are also affected by inflation rates.
Certain climates require specific construction materials that can endure extreme heat or cold, impacting overall costs. Places with extreme climates may also need to account for additional maintenance costs in their recurring budgets.
Build maintenance into the City budget and establish partnerships with local organizations, business groups, and adjacent property owners to participate in maintenance efforts. Build local pride and stewardship in the community.
Topography and Geology
Natural site conditions can impact construction processes and required materials. Particularly soft soils might be prone to erosion or require additional construction steps, while harder bedrocks might impact construction duration.
Site complexity and incomplete site analysis can result in unanticipated costs, such as finding an unexpected utility line or moving a drain which was not accurately noted in original drawings. Ensure contingency costs are included in total budgets to cover such circumstances.
