How are change orders handled on splash pad projects?

Change orders document any departure from the original contract scope and must be signed by both parties before the work proceeds. Common splash pad change orders include unforeseen subsurface conditions (rock, contaminated soil, abandoned utilities), owner-requested feature upgrades (adding a tipping bucket, swapping in LED lighting), code-driven additions (increased GFCI protection after inspector callout), and material substitutions (price escalation on stainless components). Each change order line-items labor, materials, equipment, overhead, profit, and the cumulative effect on contract sum and substantial completion date. Owners should require detailed cost breakdowns rather than lump-sum pricing. Contingency budgets of 5-10% on private projects and 10-15% on public projects absorb typical change-order activity. Best practice: weekly project meetings with documented logs, formal RFI (Request for Information) and PCO (Potential Change Order) processes, and an owner-side construction manager reviewing every PCO before approval.
