NMCB Specific 109 Construction Operations Fundamentals Flashcards
Describe the three levels of Construction Management.
Level I Construction management is used at the Operations Officer’s (S3) or detail OIC’s level. The primary concern of S3 is management of the overall unit’s tasking. The timeline for a Level I barchart will show months of the deployment and the line items will be individual projects.
Level II Construction management is used at the company level. Each company may have several projects to manage. The easiest way for the company commander to manage these projects is with a Level II barchart. The timeline for a Level II barchart will show weeks and the line items will be master activities for that particular project.
Level III Construction management is used at the crewleader’s level. The crewleader’s focus is on his/her particular project. The day-to-day activity of the project is managed by the crewleader. The timeline for a Level III barchart will show days and the line items will be construction activities.
Define the acronym “CPM”
Critical Path Method
What are the steps of project management?
Master Activities After careful review of the plans and specs, the job is broken down into discreet activities called master activities. These are based on the 16 divisions established by the Construction Specification Institute (CSI).
Construction Activities Master activities are further broken down into construction activities. Construction activities are generally less than fifteen days in duration and require the same resources through the entire duration.
Estimating The resource requirements for each construction activity are then evaluated. All of the materials, tools, equipment (including safety related items) and manpower requirements are identified and listed on the Construction Activity Summary (CAS) sheet.
Logic Network The construction activities are then laid out logically from the first activity to the last showing the relationship or dependencies between activities.
Construction Schedule An estimated start and finish date for each activity is determined based on the sequence and durations of construction activities. A critical path is identified to help focus management attention on those activities which cannot be delayed without delaying the project completion date.
Tracking Resources Crewleaders are required to take action to ensure the necessary resources are available on the project site on the day the work is to be performed. For materials on site this will be as easy as submitting a 1250-1 to MLO several days in advance. For local purchase requirements, such as a concrete request to MLO, a request may be required several weeks in advance.
Controlling Resources The crewleader is responsible for on site supervision of all work performed. Productive employment of available resources to accomplish assigned tasking is the greatest challenge to the crewleader.
What is the purpose of the Crewleader’s Handbook?
The Crewleader’s Handbook is the single document most widely used today for construction planning and execution by the men and women of the Naval
Construction Force (NCF). The handbook is designed for NCF crewleaders who want a dependable and comprehensive guide for construction planning and execution. While it is intended to be the primary tool for construction planning and execution, it is only one of many references useful to the crewleader.
What is the purpose of the NAVFAC P-405?
The Seabee Planner’s and Estimator’s Handbook is a technical GUIDE for planning and estimating construction projects undertaken by the Naval Construction Force (NCF). The handbook provides information on estimating construction work elements and material quantities, including equipment and manpower requirements. Prepared by Seabees for Seabees, the handbook is specifically for use in typical Seabee construction projects, and is designed for flexible application to projects of varying size, scope, and conditions. Tables for estimating labor have been provided to show the number of man-hours required for each work function.
Define “Project Scope”
Project Scope “The work that needs to be accomplished to deliver a product, service, or result with the specified features and functions.”
Define “Direct Labor”
Direct labor includes all labor expended directly on assigned construction tasks, either in the field or in the shop, which contributes directly to the completion of the end product. Direct labor must be reported separately for each assigned construction task.
Define “Indirect Labor”
Indirect labor is labor required to support construction operations, but does not produce and end product itself.
Define “Overhead Labor”
Overhead labor is not considered to be productive labor because it does not contribute directly or indirectly to the end product. It includes all labor that must be performed, regardless of the assigned mission.
What is the purpose of the Production Efficiency Factor (PEF)?
The PEF is intended to adjust for factors which will make us more or less productive than the average Seabee. In calculating a PEF consider only those factors which affect us while we are on the job.
What production elements are included in the Production Efficiency Factor (PEF)?
Workload
Site Area
Labor
Supervisor
Job Condition
Weather
Equipment
Tactical/Logistical
What is considered to be an average production factor?
67% (No Impact)
What is the purpose of the Delay Factor (DF)?
The Delay Factor is used to adjust Man-Day estimates based on the fact that not all construction operation will be under average conditions.
How often must a crewleader calculate a Delay Factor (DF)?
The crewleader must calculate a DF for every construction activity
What is the equation for determining the Delay Factor (DF)?
We can find the DF by dividing the average Seabee PEF (67) by the PEF of our construction activity.
What is the Man-Day Capability Equation?
MC = DL x WD x ME x AF
DL is the number of direct labor assigned
WD is the number of available workdays
ME is the number of man-days expended in a typical workday
AF is the amount of time that a Seabee is actually on the job
What is the purpose of the Man-Day Capability Equation?
We can use the Man-Day Capability equation to determine the direct labor manning for a detail if we substitute tasked man-days for MC and plug in the availability factor (AF), the man-day equivalent (ME) and the number of available workdays (WD) from our deployment calendar.
How often does the battalion submit a SITREP to higher headquarters?
Monthly
