Occupied Park Renovation: Absorbing a Council-Added Splash Pad
A 6-acre neighborhood park renovation is under contract for design at 8% of a $2.4 million construction budget, or $192,000, with a 16-week schedule, three public meetings, and construction documents at 60% completion. The program includes a new playground, perimeter loop trail, restroom replacement, irrigation, and 40 new trees. At the third public meeting, council directs the team to add a splash pad, and a neighborhood group asks that the 1950s stone restroom be preserved; a structural report estimates $140,000 to rehabilitate it against $260,000 for replacement. Construction must start after the spring ball season, which runs March 1 to June 15, and the ballfield must stay open throughout. The design contract has a 10% not-to-exceed change allowance. The client wants to stay within the $2.4 million and open by the following summer.
1. How do you process the splash pad and restroom changes without breaking the schedule or the budget?
Read the worked answer
Treat the two requests differently, because they are different problems. The splash pad is a genuine scope addition; the restroom question is a design option within an already-budgeted line item, so it can be resolved by evaluation rather than by a change order.
For the splash pad, respond in writing within days with three things: a scope and cost estimate, a schedule impact, and a clear statement of what the existing contract does and does not include. Assume the splash pad brings mechanical, water-quality, and code requirements the contract never contemplated; it is not a paving detail. Price the design work honestly against the 10% not-to-exceed allowance - $19,200 is probably adequate for design and coordination but not for the added public meeting and the utility work. If the allowance is insufficient, negotiate a supplemental agreement in writing before doing the work, and state the assumption in the estimate.
The rest of the answer is prioritization. Present the client a menu with the trades required: preserving the restroom at $140,000 versus $260,000 for replacement frees $120,000, which covers a meaningful share of a splash pad. Show what else must give - fewer trees, a shorter trail segment, or value-engineered site furnishings. Make the trade explicit and let the client choose on the record. Do not quietly absorb either change into the existing fee.
2. Build the construction schedule around the ball season. What are the sequencing decisions and the risks?
Read the worked answer
Start from the fixed date, not from the drawings. The ballfield must operate March 1 through June 15, which removes roughly three and a half months from the middle of the construction window and effectively splits the project into a fall-winter phase and a summer-fall phase. If opening by the following summer is the goal, the fall-winter phase must carry everything that cannot be built around an active field: restroom, splash pad, utilities, and the trail segments away from the diamond.
Sequence accordingly: mobilize in fall for demolition and utilities, complete the restroom and splash pad mechanical work before the ground freezes, protect the field with temporary fencing and a construction entrance located away from the parking lot used by league families, and stage the playground so its safety surfacing is installed in the summer phase when weather allows. Hold the trail segment that crosses the outfield for the summer window.
Risks to name in writing: winter concrete and coating work on the splash pad, which many manufacturers will not warrant below certain temperatures; an irrigation system that cannot be pressure-tested until spring; and a phased site where temporary fencing becomes a permanent-looking eyesore the neighborhood will complain about. Also flag the conflict between a summer playground installation and peak park use - the neighborhood may accept closure of the playground but not of the field.
Build the schedule with a weather-day allowance and require the contractor's baseline schedule to show the field-protection sequence explicitly.
3. What contingency, bid-document, and risk provisions do you recommend given the budget ceiling and the phased occupation?
Read the worked answer
The project has three independent ways to blow the budget - a scope addition, a preservation option with an uncertain structural estimate, and a phased site with winter work - so the bid documents need to convert each into a known quantity.
Recommend a construction contingency of 8–10% (about $190,000–$240,000) held by the owner, not the contractor, plus a separate owner's reserve for the restroom if the structural rehabilitation proceeds; the $140,000 estimate is a pre-construction number and should be presented as a range. Require unit prices for rock excavation, unsuitable soils, and additional structural repair in the restroom, so those items can be bought without a change order. Include an allowance for irrigation as-built adjustments.
For the phasing, put the ballfield protection, the construction entrance location, and the working hours directly in the specifications as enforceable requirements, not notes, and tie them to the schedule. Specify that the contractor must submit a phasing plan for approval and that staging in the field is not permitted.
Finally, address the risk that the two changes push the project past the ceiling. On the record, recommend the client adopt a prioritized list at 90%: what will be deleted first if bids exceed $2.4 million. Having that conversation before bid opening is far cheaper than having it after.
