Calculate design specifications or cost, material, and resource estimates, and prepare project schedules and budgets.

I have to send the preliminary cost estimate and schedule for the retrofit project at 412 Dock Street to the project manager and the client on Friday. Open the design estimate workbook, confirm material unit rates for steel and insulation match last month's procurement sheet, update labor hours for the revised sequence, recalc totals so the contingency shows correctly, and attach the PDF estimate to an email to Javier in projects and to Priya in client services.

Before I send the estimate to Javier and Priya, make it easy to approve: put the total cost and schedule summary on the first sheet, list the top three cost drivers with their line-item references, make pricing lines searchable, and flag any assumptions that would make a reviewer hesitate — for example 'lead time 8–10 weeks' or 'site access limited'.

I just received an email from Priya asking for a firm price and schedule for the dock retrofit, but the supplier replies on steel lead times are unclear and my contractor hasn't committed labor rates. I'm worried giving a number will lock us into unrealistic dates or costs. I cannot tell Priya the uncertainty without seeming unprepared. Should I provide a provisional estimate with clear assumptions and an ask for two-week leeway, or hold until rates are nailed down?

On virtually every retrofit estimate I chase suppliers and contractors the day before a client deadline, which forces last-minute changes and damages our reputation for reliable schedules. What process change or habit would prevent that recurring scramble so lead times and labor rates are confirmed earlier in the estimate cycle?
