Abbreviations
• MC = Total Manday Capability of Direct Labor Personnel (projects + training)
• DL = Number of Direct Labor Personnel Assigned
• WD = Number of Available Workdays in the Deployment
• ME = Manday Equivalent (converts typical workdays to 8 hour mandays)
• AF = Availability Factor

Manday Capability
• In order to calculate the construction activity duration's, you must first understand the Manday Capability Equation.
• The equation used to determine the direct labor manday capability at the mainbody site and each detail site is as follows.
![Page 6: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/6.jpg)
Manday Capability
Manday Capability (MC)- the total number of mandays that a NMCB, DET, DFT, etc. is able to produce within a specified period of time.
![Page 7: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/7.jpg)
Direct/Indirect/Overhead Labor
• Direct Labor personnel are those whose efforts contribute to project work-in-place (WIP).
• Indirect labor personnel provide project support and include mechanics, expeditors, EA’s (except when surveying), MLO / CTR, Staffs and the Ops / QC staff.
• Overhead labor personnel provide battalion support such as disbursing, galley ops, personnel, admin and supply.
![Page 8: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/8.jpg)
Workdays
• Workdays (WD) - The number of available workdays is the total number of calendar days minus all off days.
• Off days may include: Sundays; half of the Saturdays; all holidays; battalion turnover (up to 10 days for mainbody); one day for mid-deployment party; and one day for the change of command.
![Page 9: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/9.jpg)
Manday Equivalent
• Manday Equivalent (ME) - is the actual manhours worked “swinging hammers” on the job site during a workday. It is the length of the workday, minus lunch, minus breaks minus travel time to and from the job site (including lunch), divided by 8 (the number of hours in a manday).
![Page 10: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/10.jpg)
Availability Factor
• Availability Factor (AF)- Takes into account that Seabees assigned as direct labor are not available 100% of the time.
• About 20% of the direct labor personnel’s time is lost to : leave, liberty, inspections, quarters, medical, dental, haircuts, military drills, battalion indoc, watches, collateral duties, etc.
![Page 11: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/11.jpg)
Availability Factor
• Availability Factors for planning purposes are provided by higher headquarters.
• They vary between .60 and .90 depending on the deployment site.
• The typical percentages are .75 for mainbody sites and .85 for detail sites.
• The typical percentage for contingency construction is .90.
![Page 12: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/12.jpg)
Example #1
• How many Mandays of construction can a det with 60 direct labor personnel do in a deployment with 150 workdays, an availability factor of .80 and a manday equivalent of 1.125?
![Page 13: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/13.jpg)
• MC = DL x WD x ME x AF
• MC = 60 x 150 x 1.125 x .80
• MC = 8,100
•Answer #1
![Page 14: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/14.jpg)
Example #2
• How many Direct Labor personnel would be required for a detail tasked to do 4,000 mandays in a deployment with 150 workdays?
• Use 1.125 as the manday equivalent and .90 for the availability factor.
![Page 15: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/15.jpg)
Answer #2
• DL = MC / (WD x ME x AF)
• DL = 4,000 / (150 x 1.125 x .90)
• DL = 4,000 / 151.875
• DL = 4,000 / 151.875 = 26.337 or 27
![Page 16: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/16.jpg)
Example #3
• How many Workdays would it take for 70 direct labor personnel to do 3,150 mandays of construction with an availability factor of .75 and a manday equivalent of 1.125?
![Page 17: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/17.jpg)
Answer #3
• WD = MD / (DL x ME x AF)
• WD = 3,150 / (70 x 1.125 x .75)
• WD = 3,150 / 59.0625
• WD = 53.33 or 54
![Page 18: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/18.jpg)
Example #4
What would our Manday Equivalent be if we had a crew of 12 working from 0630 to 1700, traveled 5 minutes to and from work, 1 hour for lunch (including travel time) and two 10 minute breaks?
![Page 19: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/19.jpg)
• ME = WD - Travel time - break time -lunch / 8
• ME = 10.5 - .167 - .33 - 1 / 8
• ME = 1.125
Answer #4
![Page 20: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/20.jpg)
Example #5
• If a crew of 8 reported 125 mandays direct labor in a month with 21 workdays and a manday equivalent of 1.125, what was the actual Availability Factor?
![Page 21: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/21.jpg)
Answer #5
• AF = MD / (DL x WD x ME)– AF 1.125 IS FOR MAIN BODY ONLY
• AF = 125 / (8 x 21 x 1.125)
• AF = 125 / 189
• AF = .6613756 or 66%

SMEAC #1
• Situation: Dayton peach accord requires deployment to NATO forces to Bosnia to which the United States has committed 5,000. Permanent and temporary campsites are required to house U.S. Forces.
• Mission: Construct campsite to house JTF forces. Construct one (1) 750 man tent camp. Provide for repair of runway for C-130 aircraft. Convoy security will be provided by JTF as requested.

SMEAC #1 cont.
• Execution: Be prepared to deploy with in 5 days, advise ALCON when available for airlift. Provide specific airlift/sealift requirements to 2NCB within 48 hours. Identify Class IV materials required for camp construction within 72 hours. Upon completion of tasking, redeploy to originating site (approx. 60 days).
• Administration: Operate own self-sufficient camp. Resupply requests through JTF. CESE support through own command, require anticipated schedule for airlift within fire days of arrival.

CONVERT MANHOURS TO MANDAYS
• MD = MH / 8 hour in a workday
• MD = 7,501 / 8
• MD = 937.625 or 938
![Page 33: 106A MAN-DAY CAPABILITY](https://reader035.vdocument.in/reader035/viewer/2022062305/56815a9a550346895dc81801/html5/thumbnails/33.jpg)
FORMULA FOR MANDAY CAPABILITY
• DL = MD / WD / ME / AF
