The sawmill, its vendors, the utility and every figure are composite and illustrative; the methods and research cited are real.
How the Worksheet Is Organized
The full worksheet for the Tygart Ridge Hardwoods kiln has 41 rows grouped under the work breakdown structure codes. Its columns hold the activity, the most likely duration in working days, low and high values where a range applies, the basis type, the source document, the person who supplied the figure, the key assumption and a confidence rating of high, medium or low. Basis types are vendor quotation, three-point estimate, analogous estimate, historical record and expert judgment. The rows below show each basis type and the estimates that matter most to the schedule.
Steve McConnell argues that estimates should be built from counts and historical data wherever possible, and that judgment alone should be the last resort (McConnell, 2006). The worksheet follows that order.
Selected Rows
2.1 to 2.5, kiln delivery. Vendor quotation. The kiln vendor's signed quotation gives 16 weeks from order to shipment from its plant, plus about one week of freight: 85 working days in all. Supplied by the vendor's sales engineer. Assumption: order placed with a 30 percent deposit. Confidence: high, because the date is contractual.
3.2, utility service upgrade. Three-point estimate. The utility's engineer emailed a range of 26 to 34 weeks. The worksheet uses 24 weeks as the low value, from the utility's fastest comparable job last year; 30 weeks as the most likely, the middle of the utility's range; and 44 weeks as the high value, from a neighboring mill whose transformer arrived that late during the recent shortage. The weighted mean, the low plus four times the most likely plus the high, divided by six, is 31.3 weeks, with a standard deviation of about 3.3 weeks, the high minus the low divided by six. This weighting is the three-point method the Project Management Institute lists among its estimating techniques (Project Management Institute, 2021). Supplied by the utility engineer and the neighboring mill's manager. Assumption: no substation work is required. Confidence: low.
The utility's own range did not include the worst case a neighboring mill had lived through, so the worksheet widened the high value rather than trusting the email alone.
2.3.1 to 2.3.3, kiln installation. Analogous estimate. A mill of similar size installed the same model in six working days. The worksheet adjusts this to eight, adding two days for the condensate trench our pad needs. Supplied by the maintenance lead. Confidence: medium.
3.4.1 and 3.4.2, boiler installation. Vendor quotation. The boiler contractor quotes seven working days on site after delivery. Confidence: high.
5.2.1, county building permit. Historical record. The county's permit issue log for the last year shows a median of 14 working days for commercial accessory structures. Supplied by the county permit office. Confidence: medium.
5.2.3, electrical permit and inspection. Historical record. The issue log shows a median of eleven working days for electrical permits. Confidence: medium.
5.2.2, state air quality permit. Historical record with a range. The state agency's public log for general permits for small wood-fired boilers shows a median of 19 working days and a longest recent case of 45. Most likely 19, high 45. Confidence: medium.
6.1 and 6.2, operator training. Vendor quotation and published schedule. Vendor training takes three days at commissioning. The kiln drying short course runs five days and is offered twice a year; the worksheet uses its spring dates. Confidence: high.
7.1, trial charge. Three-point estimate. The vendor's nominal cycle for 4/4 red oak from air-dried condition is eight days, plus about two days for equalizing, conditioning and cooling. Low 8, most likely 10, high 14. The high value reflects the Forest Products Laboratory's guidance that a first charge in a new kiln often needs schedule adjustment (Simpson, 1991). Supplied by the lumber grader. Confidence: medium.
Reserve. A final row holds ten working days of schedule reserve, owned by the operations manager, to be released only for risks recorded in the risk register.
What Would Change the Estimates
Three conditions would change the worksheet most. If the utility requires substation work, the utility estimate must be rebuilt. If the kiln vendor's plant falls behind, its contractual date may still slip, so the operations manager will ask for a production slot confirmation at order. If the air permit draws public comment, its duration could exceed the high value.

Reading the GM 592 Unit 5 instructions
GM592 Unit 5 asks you to document the basis of your project's estimates. Build a worksheet with one row per activity and columns for the most likely duration, low and high values where uncertain, the basis type, the source document, the person who supplied it, the key assumption and a confidence rating. Prefer bases in this order: contractual quotations, historical records and counts, analogous projects adjusted for differences, three-point estimates for uncertain work, and expert judgment last. For three-point estimates, state the weighting method and show the mean and standard deviation. Explain any value that departs from a supplier's own figure. Hold reserve as a separate line with an owner rather than padding each task. Close with the conditions that would change the estimates most. Expect about five pages built on the worksheet, citing estimation sources in APA 7.
How this GM592 Unit 5 example is built
The organization section describes 41 rows and five basis types, citing McConnell on preferring counts and history to judgment. Selected rows follow: kiln delivery at 85 working days from a signed quotation, rated high confidence; the utility upgrade at 24, 30 and 44 weeks, weighted to 31.3 with a standard deviation of about 3.3 using the PMBOK guide's three-point method, and the highlighted sentence explains the widened high value; installation analogous at eight days; boiler installation at seven; county building and electrical permits at medians of 14 and 11 days; the air permit at 19 days with a high of 45; training from vendor and course schedules; and the trial charge at 8, 10 and 14 days, citing Simpson's operator manual. A ten-day reserve row and three conditions that would change the estimates close the worksheet.
Reading the GM592 Unit 5 grading rubric
GM592 instructors look for estimates that a reader could check and challenge. Each row should name its basis type, source document and supplier, so the figure can be traced. Preferring quotations and records over judgment earns credit, and confidence ratings show the writer knows which numbers are soft. Three-point estimates should state the method and show the mean and spread. Explaining a departure from a supplier's own range carries weight, because it shows independent judgment. Reserve held as one owned line, rather than padding, makes uncertainty visible. Naming what would change the estimates helps the project watch the right numbers. McConnell's Software Estimation, the PMBOK Guide and Simpson's Dry Kiln Operator's Manual provide the references in APA 7.
GM592 Unit 5 help from the desk
Many GM592 Unit 5 worksheets give durations with a basis column that says experience or estimate, which no one can check. Others pad every task quietly instead of holding a visible reserve. A common gap is the supplier's range: accepting a vendor's or utility's figure without asking whether it covers the worst recent case can hide the project's largest risk. Some writers use three points without saying how they were combined. Give every row a basis type, document and supplier, prefer records to judgment, show the method for ranges, explain any adjustment, hold reserve separately with an owner and state what would change the numbers.

GM592 Unit 5 questions, answered
Is PERT the same as a three-point estimate?
PERT is one way of combining three points: the most likely value counts four times, the optimistic and pessimistic once each, and the total is divided by six. A triangular estimate weights all three equally. Because the two methods rarely agree, a worksheet states which one it applied. The example uses the weighted version for the transformer and prints the standard deviation next to the mean.
Why hold reserve separately instead of padding each task?
Padding hidden in every task is invisible, tends to be consumed by whoever runs late, and cannot be reported. A single reserve line, sized from the estimates with the widest ranges and owned by one person, makes the uncertainty visible and its use a decision. Graders in planning units commonly look for that separation.
Where can I find a free GM592 Unit 5 sample paper?
This page carries a full GM592 Unit 5 estimate basis worksheet for a sawmill's dry kiln, with sourced durations, a three-point utility estimate, a reserve line and APA 7 references.
Why widen the utility's high value beyond its own range?
The utility's emailed range of 26 to 34 weeks did not include the 44 weeks a neighboring mill waited for a transformer during the recent shortage. Using that real case as the high value keeps the worst plausible outcome in the estimate.
Where did the permit durations come from?
From historical records: the county's permit issue log for the past year and the state agency's public log of general permits for small wood-fired boilers, using the median and the longest recent case.
