| Separate fixed, per-court and capacity-dependent costs |
Model total investment as fixed setup F + court count n × incremental court cost C + capacity upgrades U(n). Fixed setup may include survey and mobilization; per-court work includes the enclosure, surface and designed base. Capacity upgrades can include drainage, electrical supply, parking, toilets and staff areas. |
Shared setup does not mean every project cost falls proportionally. Ask the designer and authorities which requirements change at two or four courts, and request a separate price for each layout. Include circulation, maintenance access and the selected courts’ foundations in each site plan. |
| Compare one, two and four courts using explicit assumptions |
Hypothetical example only: with F = $20,000, C = $40,000 and no assumed capacity upgrades, one court totals $60,000, two total $100,000 ($50,000 per court) and four total $180,000 ($45,000 per court). This shows fixed-cost sharing; it is not evidence of supplier discounts or actual installation prices. |
If the four-court layout also needs an assumed $30,000 capacity upgrade, its total becomes $210,000, or $52,500 per court. Replace every assumed input with a scoped proposal. Keep opening cash, lease or land costs, financing and taxes visible outside this simplified construction example. |
