2.3.2 Project Management Cycle
For the stages of construction project management is a part that cannot be separated from each other, because it will be interconnected and related. In general, the stages are described in the management cycle diagram as follows.
Source: PT. WIKA WG-KSO
Figure 2. 3 Project Management Cycle
1. Planning
The Project Planning stage is the initial stage.
An idea or thought about the initial plan before the project starts. The planning function is beneficial because it can be used to supervise and control activities as well as select and assign necessary activities.
2. Organizing
This organizing stage is in the form of actions carried out after planning to unite a collection of human activities that have their own work so that they relate to each other in a certain way and interact with their environment in order to support the achievement of goals/objectives efficiently. This stage is a guideline for the implementation of functions where the division of duties and the relationship of responsibilities and authority are clearly visible.
3. Staffing
Often, workers are put into a cycle or management function. Therefore, an organizing system will be formed if these staffing are combined. Manpower procurement is an example of staffing. The management cycle regulates all things about the workforce, including the number and competencies required, recruitment, training, and selection for jobs in the company.
4. Actuating
This actuating is in the form of an action to harmonize all members of the organization in implementation activities, as well as so that all members of the organization can work together in achieving common goals
5. Monitoring & Controlling
Supervision is carried out to avoid irregularities in implementation. This includes controlling, monitoring, and reviewing, as well as making corrections where necessary to ensure that the results of the activities are in accordance with what has been determined. Therefore, the results of activities carried out under this supervision are always measured and compared with the plan.
Therefore, quality standards, deadlines, and budgets have been created.
2.4 PROJECT WORK PROGRAM
A project program is an activity that takes a long time to solve many challenges and usually goes through a long process, usually the process is sequential and interconnected activities. It starts with the planning process and ends with implementation. All work activities in the field are documented in the form of reports, consisting of work plans and results, for the purpose of controlling and supervising the implementation of work.
All work outcome reports must be prepared by the implementing coordinator and approved by the project owner. Work report can be in the form of daily reports, weekly reports, and monthly reports, as mentioned earlier in the rights and duties of the field section.
The following is an example of the SHE (Safety Health Environment) section work program, here are examples of some of the work programs and their objectives:
A. SHE Meeting
1. Safety Morning Talk
Safety Morning Talk is a gathering activity for all staff and workers. It is not much different from the Toolbox Meeting activity, but in this activity after the briefing, joint gymnastics will be carried out. This activity is carried out every Thursday morning.
2. Toolbox Meeting
Every day, project implementers and project safety officers gather at the Toolbox Meeting to be briefed on the work to be done. Safety officers provide directions on Occupational Safety and Health (K3) and inspect workers' personal protective equipment (PPE) if there is damage to the PPE used.
3. Safety Induction
Safety Induction is a K3 briefing activity for workers who have just started work. This activity must be carried out with the aim that all workers or guests who enter the project area understand the K3 rules that apply to the construction area.
B. SHE Training
1. P3K (First Aid in Accidents) 2. 5R
5R (concise, neat, clean, care and diligent) is the motto of work professionalism at WIKA.
3. PPE (Personal Protective Equipment) C. Work Permit
1. Making high-risk work permits (daily report). Work permits consist of general work permits and special work permits.
General work permits cover many jobs in one report, but special work permits in the report are made separately according to the work being done.
The following is the process documentation program for the Construction of Buildings 1 and 2 of ITB Innovation Park Bandung, namely the documentation of 8 photo spot points. The documentation will use the drone camera for weekly and monthly photo updates. In addition, the collection of work documentation photos can use digital cameras or mobile phone cameras to retrieve work items that are being worked on.

2.5 MANAGEMENT OF PROCUREMENT OF GOODS AND SERVICES Procurement is an activity to obtain goods/services by Ministries/Institutions/Regional Apparatus Work Units/Institutions (K/L/D/I) whose process starts from planning needs to the completion of all activities to obtain goods/services.
Procurement usually begins with planning, preparation, procurement, contract execution, and handover of goods or services.
Presidential Decree No. 12 of 2021 concerning Amendments to Presidential Decree No. 16 of 2018 concerning the Procurement of Goods or Services regulates this type of procurement.
2.5.1 Project Auction
In construction projects, public auctions and limited auctions are two different types of procurement processes for goods or services. In a public auction, all qualified service providers can participate, while in a limited auction only providers of goods or services invited by the auction maker can participate. The choice of auction type usually depends on the size of the building, complexity, cost, and time of work.
The opening of the bidding document is an important stage in the process of selecting government goods and services providers. Because bidding documents are the basis of competition to choose government goods or service providers, the opening of bidding documents is carried out officially and witnessed by all auction participants. In this event, the government procurement committee provides all data contained in the bidding document to all participants.
The Geudng 1 and 2 ITB Innovation Park Bandung Teknopolis Development Project uses an open or public auction where the auction is carried out openly. Decree of the Minister of Education, Culture, Research, and Technology of the Republic of Indonesia Number 255/P/2022 concerning the Determination of the Winner of the Procurement of Construction Work for the Construction of Buildings 1 and 2 ITB Innovation Park Bandung Teknopolis stipulates that the winner of the procurement of construction work for the Construction of Buildings 1 and 2 of ITB Innovation Park Bandung Teknopolis is as follows:
