establishing the UCD. UCDs, except for specific projects with critical completion dates, are established by the battalion. When delay of a UCD becomes necessary, the battalion must advise 2ndNCB/ 3rdNCB in writing of the cause and estimated duration of the delay. The UCD reflected in the SITREP, however, shall not be adjusted until approved by 2ndNCB/3rdNCB. When adjusting UCDs, the battalion takes appropriate action to ensure that only the minimum number of UCDs are affected by the delay.

BARCHARTS

Barcharts are used to plot and track your progress as you work your project. They graphically show you if you are ahead, behind, or on schedule. Barcharts help you track how well you are doing against what you had planned. At the end of each month you need to update your level II barchart with the actual man-days expended and percent completed. To plot these figures, you need to total the man-days expended for direct labor (from your time cards) and obtain the percent complete from the SITREP. To make a progress curve you just connect the dots. If the progress curve is above the planned progress curve, your project is ahead of schedule; if below, you are behind. As previously stated, man-days expended have nothing to do with percent complete. However, a rough comparison can be made between the man-days expended as a percent of the total man-day estimate versus the scheduled percent complete. A large variation in these numbers indicates a problem. Figure 2-26 is a level II with an actual progress curve and cumulative man-days figures. This illustration shows all the information plotted through the end of the project.

PHOTOGRAPHIC COVERAGE

The battalion shall provide to 2ndNCB/3rdNCB on a monthly basis at least two color slides of each active project. These slides must arrive not later than the fifth of each month. Vantage points are chosen based on the broadest coverage. The same view should be used for slides taken during the following months. Consistency in vantage points and view help show sequence of construction. Include slides/prints of working crew members and major construction evolutions that depict Seabees in action. It is the crew leader's

responsibility to produce photographic proof of the project's progress. Be sure the slides/prints show a commitment to a quality product, teamwork, and zero safety violations.

SAFETY

The battalion safety office is not responsible for safety on your jobsite. YOU ARE!!! According to the NCF Safety Manual, COM2NDNCB/COM3RDNCB- INST 5100.1 series, the battalion safety office administers the battalion safety program and provides technical guidance. It is the crew member, the crew leader, the project supervisor, the company chief, the company commander, the Ops officer, and the commanding officer who are 100 percent responsible for safety on the jobsite. If you have any questions concerning safety on the project, the battalion safety office is a good place to get your questions answered. It is not the responsibility of the safety office to prevent you from doing something you know or suspect is unsafe. They do not have the staff to be present on the jobsite at all times. Safe construction is your responsibility, and ignorance is no excuse. It is your responsibility to find out how to do construction in a safe manner.

MISHAP PREVENTION

The goal of our safety program is to prevent mishaps. Seabees do not use the word accident because it implies the absence of fault (accidents happen). Mishaps most commonly result from failure to follow safe construction practices. Consider an activity to replace the deck on a marina pier. Follow the seven-step process in figure 2-27 to see how you can best avoid a mishap.
