Project control process is complex, how to arrange a “ground gas” construction practice program to guide the site

Many of our young colleagues on the project think that “the completion of the schedule is everything, the rest to the team or suppliers to complete the plan on it”, this is the mentality, the result of the project is almost all done sloppily.

This is an ideal state, planning is very easy, but “how to move forward” to ensure that the big plan is not run-off is extremely difficult, many materials signed delivery time, workers on-site time, and so on … will affect the implementation of the overall plan. How to reverse/correct construction according to the plan, it is recommended that you combine today’s article with offline lessons to learn the project progress preparation skills!

01

The construction schedule does not ground gas?

These 6 items need to be highlighted

Schedule arrangement, first of all, familiar with drawings and procedures, can be arranged according to the operation, can also be arranged by space, regardless of that type, must first do a good job of listing children!

At the same time, the schedule is not only one edition, according to the actual situation and risks of the reporting version. Drain the construction version according to the progress of the contract. No matter how row to do a number in mind, do a good job of risk avoidance, need to focus on the following 6 points:

1.1

Pay attention to the terms of the “duration” in the construction contract

The construction organization design, contract duration, phased start date and completion date in the construction contract, the agreement on the delay, adjustment, acceleration, etc. of the construction period are the basis for the preparation of the overall construction schedule plan.

Research contracts, especially with the interface of the relevant units, entry conditions, the participation of the relevant units (civil construction, curtain wall, mechanical and electrical, air conditioning, fire, etc.), such as when the civil construction is handed over, curtain wall closed, etc., to understand these are mainly for the preparation of the schedule when setting up pre-tasks.

Construction organization design preparation basis

1.2

Construction enterprise’s own “progress control objectives”

Construction schedule targets. In addition to the construction schedule targets agreed upon in the contract, each enterprise may have its construction progress targets (generally shorter than the contract objectives, to obtain insurance progress targets) to guide the preparation of construction progress plans.

Progress control objectives can be expressed as follows: Through effective progress control work and specific progress control measures, under the premise of meeting investment and quality requirements, and strive to make the actual duration of the project does not exceed the planned duration.

1.3

Focus on the “duration quota” in the contract

The duration stipulated in the term quota is the maximum duration of the construction project and the basis for the contract between the contractor and the contractor. In the preparation of the overall construction, a schedule should be based on this maximum duration standard, and strive to shorten and not exceed the limit.

Now the usual situation is that the owner to put the project into use at an early date, the contract duration is much shorter than the fixed duration, in this case, the preparation of the schedule should consider a variety of factors, the plan given to the owner can be prepared according to the contract duration, the internal and required team plan must be ahead of the contract duration because there are many hidden factors in the construction process, must consider the time required by these factors, which is also what we often say the internal tightness of the outer loose。

1.4

Focus on the “All Drawings” of the project

All design drawings of the project, including the preliminary design of the project or the expansion of the preliminary design, technical design, construction drawing design, design specifications, building plans, etc.

Renovation works mainly understand the proportion of materials used in the project and various materials (stone, wood, metal, etc.), to set the construction cycle of various materials in the schedule, targeted preparation of the schedule.

Also to understand whether there are special materials or new materials, new processes, such as Baosteel rust plate, Zhoushan Grand Theatre has GRG, these special materials in the schedule will let the owners feel that our schedule is very targeted, rather than uniform.

1.5

Attention to and economic and technological-related information

Relevant technical and economic information mainly refers to the construction files, geological data, environmental data, statistics, engineering nature, and so on.

Environmental data to understand the local climate, such as whether rain, snow, low temperature, high temperature and another impact of the construction season;

1.6

Construction deployment and major engineering construction programs

Construction deployment and main engineering construction program refers to the contents of the overall design of the construction organization. The preparation of the overall construction schedule shall be carried out after the construction deployment and the main project construction plan has been determined.

Construction plan determines the construction order, construction order determines the logic of the schedule, such as wallpaper, the traditional process is to install wood finish, then paste wallpaper, some projects first paste wallpaper and then install wood finish, the order of the two construction programs is completely different.

Therefore, the construction plan is an important basis for the preparation of the schedule, but also the construction schedule can not ground gas key.

02

Planning construction for the focus will affect the operation

as a focus

2.1

List all construction operations

According to the construction drawings, list all construction processes, the main items are summarized as follows:

In-field release line

Electrical and mechanical, air conditioning, fire, and other construction

Smallpox covert acceptance, sealing board

– Stone, wood, and other external processing orders

Rough cleaning

Face mounting (woodwork, hardware, wallpaper, soft bags, flooring, carpets, etc.).

Fine cleaning, completion acceptance

2.2

Schedule the logical order of the process

According to the construction plan of different projects, the logical order of construction is scheduled, generally first top surface, then the wall, after ground; According to the characteristics of the project to adopt the appropriate construction order.

Then according to the needs of the project, it is decided that the plan should be prepared according to the region, or all in the order of construction, or according to the construction flow section.

For key parts, focus on control, so that planning, especially involving the end or other construction needs to focus on control. For lagging regions should be actively coordinated response, for the problem beyond the coordination capacity should be reported promptly, to avoid greater risk.

Critical nodes

2.3

Identify the key lines for construction

The operation time of the key line directly affects the project duration! Therefore, in the early combing out is the relationship between the key lines and parallel lines, is conducive to a certain duration, cost, resources, timely adjustment of the arrangement of the best schedule!

03

Pay attention to the implementation and adjustment of the correction plan

We all know that the beginning is difficult but can be done, and whether the result is ideal is unknown. How to avoid the gap between the ideal and the display? This requires our intermediate stage tracking and implementation, and according to the degree of implementation of the phased adjustment!

3.1

Follow up on the project and adjust the schedule

According to the actual situation of the project, the current progress node landing situation analysis, summary, timely adjustment of the schedule, around the total duration target to adjust the construction rhythm, control the important node.

To check the quality of grass-roots construction, correction, adhere to the continuity and feasibility of the technology, management, strict quality control key points.

3.2

Reasonable arrangement of cross-construction of different types of work

Adjust the schedule reasonably according to the on-site conditions to ensure the total duration. Reasonable arrangement of different types of cross-construction before and after the plan.

3.3

Summarize correction

The same as the 50-phase mutual inspection, but the 80-phase mutual inspection focuses on mutual learning between teams, for the previous work in the problem summary correction, and the remaining workload planning, so that the final phase of the finishing work step by step and order.

To enforce the completion point of each node and implement the reward and punishment system;

Increase the intensity of quality inspection of the project, so that problems are found and dealt with promptly, each team to follow up step by step, for the discovery of problems to make rectification commitments, and within the commitment, period to complete.

The construction schedule is an important part of project management, planning management is a systematic project, a complete plan should reflect not only the logical relationship between the key processes and other processes before and after but also reflect the continuity and balance of construction.

It obtains the design drawings provided by the construction unit from the construction unit for construction preparation until the project is completed and put into operation for use. How to scientifically prepare the schedule is of great significance to the construction and benefit of the project.
