Part II

 

Construction drawing review phase

The main tasks including self-review by the main designer, mutual review within the discipline, drawing proofreading, external review by the drawing review organization and joint review of drawings.

 

Construction phase

Construction phase is the main content of the entire project and also focus of the work. The construction phase can be divided into temporary project, civil construction, bracket foundation, sub-station and inverter bracket, bracket installation, transformer, inverter, switchgear and related power distribution devices, battery assembly installation, line laying and system commissioning. 

Acceptance phase

Acceptance phase is the final work of the entire construction process. This phase is the key part of comprehensively check construction quality of the project, inspect the project results. The success of acceptance means the project and operate successfully and maximize the investment benefits.

 

Plan control and implementation guarantee in the project

During the construction of photovoltaic power generation project, when comparing the construction progress, it is necessary to compare the actual progress with the weekly plan progress and the monthly plan progress respectively. In case of deviation from the weekly schedule, the project department can adjust the schedule by itself; In case of deviation from the monthly schedule, the new schedule shall be submitted to the head office and the supervision engineer for approval before implementation.

When the actual progress of the project is inconsistent with the planned progress, especially when the actual progress of the project lags behind the planned progress, it is necessary to carefully explore the deviation and the causes of the deviation, and calculate its impact on the follow-up work of the project, which is comparing the generated deviation with the work free time difference (FF) of the work. If it has an impact on the follow-up work of the project, countermeasures shall be taken to adjust the construction progress and ensure the timely completion of photovoltaic power generation project.

 

Risk analysis and control method

During the implementation of photovoltaic power generation project, there will be various obstacles to the project progress. According to previous project experience and on-site investigation and analysis, there may be factors affecting the planned progress in the aspects of construction organization arrangement, construction efficiency, construction machines and tools, etc. Therefore, to comprehensively analyze the risks of the project, measures will be taken to control them. As the following table shows:

 

Plan Risk Analysis and Control Table:

Number	Risk Analysis	Control Measures	Responsible Department/Person
1	The construction plan is unreasonable and the actual progress deviation of the construction period is relatively large.	Prepare a scientific and reasonable general schedule, monthly schedule, and weekly schedule of the construction plan and control it stage by stage, correct the derivation in time.	Project manager, construction manager
2	The ability of managers is not strong and the plan execution is not enough.	Choose staff with strong management ability and technical ability to form the project department and ensure they are on duty.	Project manager
3	Low efficient construction	Carry out labor competition,premote new technology, new craft to improve the labour efficiency and execute the construction progress strictly and use advanced internet technology to control the schedule.	Project manager & construction manager
4	Material and information supply	Purchasing by invitation to bid in time, unified state control dispatch, transport for large facilities. Check quality and quantity in time when goods arrives.	Purchasing Department
5	The construction quality is not up to standard, resulting in rework	Strictly execute regulation and rules as well as SOP, following the ‘quality management system program file’ during the construction process; Make sure the execution of work responsibility to make sure the quality and reduce reworking.	Technical Department Quality and Safety Management Department
6	Design change affect the construction work	Cooperate with supervising engineers and the HQ actively to shorten the examine and review time. Adjust the resource supply plan in time.	Project Manager
7	Construction Tool Problem	Ensure the machines and tools are ready in time and in good condition. Maintenance team and duplicate part are available.	Construction Management Team
8	Fund are not ready in time	Make reasonable plans for fund use and go through the settlement procedures of progress payment as soon as possible.	Project Manager
9	Large temperature difference, bad weather etc results in reduced effective working time.	Arrange reasonable construction plan and add the construction volume in proper weather conditions	Construction Management Department

 

In short, by optimizing construction management, taking practical and effective safety measures, quality measures, optimizing construction technology and strengthening construction process management means, we can reduce construction cost and improve project construction level while ensuring construction safety, construction quality and construction progress.
