  2. Contingency Operations • References: • NAVFAC P-437, Planning Guide for Navy Facilities, Vol. 1 • NAVFAC P-437, Planning Guide for Navy Facilities, Vol. 2

  3. Contingency Operations • NAVEDTRA 12543, Naval Construction Force/Seabee 1 &C • Seabee Crew Leader Handbook • Seabee Construction Management I & II

  4. 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

  5. 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.

  6. 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.

  7. Direct/Indirect/Overhead Labor • Direct Labor personnelare 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.

  8. 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.

  9. 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).

  10. 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.

  11. 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 contingencyconstruction is .90.

  12. 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?

  13. Answer #1 • MC = DL x WD x ME x AF • MC = 60 x 150 x 1.125 x .80 • MC = 8,100

  14. 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.

  15. 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

  16. 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?

  17. 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

  18. 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?

  19. Answer #4 • ME = WD - Travel time - break time -lunch / 8 • ME = 10.5 - .167 - .33 - 1 / 8 • ME = 1.125

  20. 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?

  21. 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%

  26. SMEAC • Situation • Mission • Execution • Administration • Command and control

  27. 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.

  28. 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.

  29. SMEAC #1 cont. • Command and control: • OPCON - JTF • ADCON - NMCB 74 • Advise ADCON on arrival • Revise schedule for construction and submit weekly sitrep.

  32. CONVERT MANHOURS TO MANDAYS • MD = MH / 8 hour in a workday • MD = 7,501 / 8 • MD = 937.625 or 938

  33. FORMULA FOR MANDAY CAPABILITY • DL = MD / WD / ME / AF • DL = 938 / 56(60 - 4 days for mount out)/ 1.25 / .90 • ME 1.25 is for contingency ops only • DL = 14.88 or15

  34. RATIO • CM 6 TO 1 • WILL BE CHANGING TO 8 TO 1 BUT IT HAS NOT GONE INTO EFFECT YET • HM 100 TO 1 • IDC 150 TO 1 • YN/PN 50 TO 1 • MS 50 TO 1 LESS THEN 50 PEOPLE THERE WILL BE NO FSA’S

  35. RATIO cont. • SK UNDER 100 THERE WILL BE ONLY 1 • ET DEPENDS ON SMEAC • GM DEPENDS ON SMEAC

  36. RATIO cont. • FSA • FOR EVERY ONE MS THERE WILL BE ONLY ONE FSA’S • 1 TO 1
