W6.1_SSG_Progress Measurement using Norzok -104 on EPC project (Standard Activity Breakdown point of view)


After we sign the project contract, we start doing the job. To be able to measure the project, monitoring   progress, reporting, and mitigation (if applicable), we need to develop a tool to measure it.


As a progress measurement is a tool that can be used to measure project progress. This progress measurement is corresponding with work breakdown structure; hence it is possible to use Norzok-104 with SAB point of view as demonstrated on this writing.


In order progress can be identified in the lower level, it needs to develop weighting factor to each level of detail.

Level 0- Project

The value of the project is based on the contract.

Figure 1. Contract Value

Level 1- Phasing

Phasing Progress (Level 1, SAB View) and will be broken down in to following Breakdown Value, progress, and earn. This level is divided in to Project Management, Engineering, Procurement, and Construction.

Figure 2. Level 1 Budget, Plan, and Earn from SAB point of view

Level 3- Function Facility

Level 3 will be broken down in to Functional detail where it is one level more detail compared to phasing (Level1). Fore example: Project Management consist of Common & offside facilities, well cluster and central processing, utilities facilities, Jetty and offloading facilities, sales gas pipeline, and gas custody metering.

Figure 3. Level 3 Budget, Plan, and Earn  on Functional Level

Level 4- Sub Function Activity

Level 4 is Sub Function Activity Breakdown. This is the lowest level of progress input for this project. For example, “common and offside facilities (level-3)” in the “project management (level-2)” consist of earthworks and buildings.

Figure 4.  Level 4 Budget, Plan, and Earned  on Sub Functional Activity Level


There are some criterions to be an acceptable progress measurement. Some of them are:

ü  SAB point of view reflects the control of project in term of phasing.

ü  It shall cover all deliverable list to be executed.

ü  It shall in line with other project controlling tools such as scheduling, and cost control, and estimating.

ü  It shall accommodate lesson learn requirement to be used later on.

ü  Integrated with document system, where the progress can be validated.

ü  Progress can be measure in term of cost, hours, quantity, and schedule.



Below progress measurement consider that Standard Activity Breakdown point of view as top level where it can be divided in Project Management, Engineering, Procurement, and Construction. Below is the Mapping of the EPC Stages using  Z-014 WBS Standard Activity Breakdown (SAB).

Figure 5. NORZOK Z-014 (SAB) on EPC Stage

For the progress monitoring purpose, the progress plan, progress achieved, Plan value, and earn value of each product (PBS view) is shown in the figure 4 below. As demonstrated in the figure 4., as of October 05, 2013, below are the project status:

Progress Plan = 20,93%

Progress Earn = 15,76%

Plan Value = $20,926,565

Earn Value = $17,754,501

Schedule Performance index (SPI) = 0,84 à Behind Schedule

Above SPI is overall SPI. If we go to more details we can find that some of the activities are ahead schedule. Hence, we have to go more detail to find which activities that are critically behind the schedule and focus to it to speed up the progress.

Figure 6. List of activities that ahead schedule

Figure 7. List of activities that critically behind schedule where SPI < 0.5


Alternative selected is Norzok Z-014 Standard Activities Breakdown for Onshore Gas Production & Pipeline Projects to level 4 of activities detail.


Based on the status above data, project is behind the schedule where SPI 0,84 < 1,0. Even though, there some activities that ahead schedule. To improve the SPI, we need to focus on the activities that critically late i.e. figure.7.

One response to “W6.1_SSG_Progress Measurement using Norzok -104 on EPC project (Standard Activity Breakdown point of view)

  1. Same here……… Take your time, and do your research and then you can demonstrate clearly that you know and understand what you are doing.

    Why is this important? Because sooner or later, instead of having to defend or explain what you have done to me, you will have to be explaining it before you bosses. Better you make the mistakes here with me so I can help you fix them rather than looking foolish before you bosses.

    Make sense?
