The Permitting Critical Path
Your firm is managing design and construction administration for a 3.2-mile greenway along an irrigation canal. The $4.8 million project must be substantially complete within 18 months to satisfy a grant. The canal owner requires construction only between October 15 and February 28 because of irrigation deliveries. The project needs a floodplain permit with a 90-day agency review and a 30-day public comment period, a cultural resources survey, and relocation of 1,100 feet of fiber-optic line. The environmental document is a categorical exclusion, but the state historic preservation office has asked for additional tribal consultation after a ground-disturbance area was expanded by 0.6 acre. The design is at 60%. The contractor has not been selected, and the owner wants to advertise in four months. Your team has 2.5 full-time equivalents and a 10% contingency. The grant has a 5% cost overrun cap and no schedule extension.
1. Identify the critical path and what must happen before advertisement.
Read the worked answer
The critical path runs through the additional tribal consultation and SHPO concurrence, because those clearances gate ground disturbance and the floodplain permit application. The floodplain permit has a 90-day review and a 30-day public comment period, so it must be submitted complete and early. Fiber relocation has a long lead time and must be under contract before the October 15 construction window. Design at 60% must reach 100%, with specifications, before advertisement.
Advertising in four months is possible only if tribal consultation closes and the flood permit application is deemed complete within about six weeks. Work backward from the February 28 canal shutdown: set a construction start of October 15, allow 60 days for bid and award, and advertise 30 days before that. Give the tribal consultation and flood permit zero float. If either slips, the construction window is lost and the project waits a year.
2. Build a risk register with the top risks, triggers, and responses.

Tribal consultation delay: trigger is no response or a new information request within 21 days. Response: schedule a government-to-government meeting, fund a cultural monitor, and prepare an alignment that avoids the 0.6-acre expansion. Owner: project manager.
Flood permit incomplete: trigger is agency comments requiring hydraulic revision. Response: hold a pre-application meeting, submit hydrology and hydraulics early, and protect 20% design contingency.
Fiber relocation: trigger is an unsigned utility agreement by month 3. Response: escalate to the owner, fund utility design, and evaluate temporary relocation.
Construction window: trigger is award after September 1. Response: evaluate winter work restrictions, negotiate alternate access, or delay to the next season.
Grant overrun: trigger is bids more than 5% over budget. Response: value engineering before bid and use owner contingency.
3. How do you communicate a likely schedule slip to the owner and protect the grant?

Use a one-page monthly dashboard with schedule, cost, top risks, and decisions needed. Show the critical path and float, not just percent complete. Tell the owner now that 18-month completion is at risk if tribal consultation is not resolved by a date certain. Give a recovery plan with two options: compress design and bid, or negotiate a one-season extension. Do not hide the issue.
Document agency correspondence and decisions in a log. Hold a weekly 30-minute stand-up with the owner, design lead, and permit consultant. If the grant truly has no schedule extension, recommend a pre-bid meeting and a construction manager at risk only if procurement allows it; otherwise reduce scope before bid so the 5% overrun cap is not breached.
