Recommended | Volume Hardcover project complex process, how can you arrange a “ground gas” construction plan to guide the site?
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 version, according to the actual situation and risks discharged from the reporting version, according to the contract schedule out of the construction version. 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. 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 and acceleration of the construction period, etc., are the basis for the preparation of the overall construction schedule plan.
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 own construction progress targets (generally shorter than the contract objectives, in order to obtain insurance progress targets) to guide the preparation of construction progress plans.
3. Pay attention to 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 schedule should be based on this maximum duration standard, and strive to shorten and absolutely not exceed the limit.
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. and the proportion of materials required for the project (wood / stone / gold, etc.) in order to set the material construction cycle in the schedule, targeted preparation of the schedule.
Attention to and economic and technological-related information
Relevant technical and economic information mainly refers to the construction archives, 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 other impact of the construction season;
6. Construction deployment and major engineering construction programmes
Construction deployment mainly refers to the construction organization’s overall design content. The preparation of the overall construction schedule should be carried out after the construction deployment and the main project construction plan have been determined. The construction plan determines the construction order, the construction order determines the logic of the schedule, (such as wallpaper, the traditional process is to install wood finishes first, then paste wallpaper, a project standard is to first paste wallpaper and then install wood finishes, 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.

Construction schedule preparation – practical steps
Step 1: List all construction operations
According to the construction drawings, list all construction processes, the main items are summarized as follows:
(1) Enter the field to put the line
(2) Electrical and mechanical, air conditioning, fire and other construction
(3) Grass-roots construction
(4) smallpox covert acceptance, sealing board
(5) Stone, wood and other external processing orders
(6) Wet job completion time node (including paint, stone, tile, etc.).
(7) Rough cleaning
(8) Surface installation (woodwork, hardware, wallpaper, soft bags, flooring, carpets, etc.).
(9) Fine cleaning, completion acceptance
Step 2: Schedule the logical order of the process
According to different engineering construction programs, the logical order of construction is scheduled, generally first top surface, then wall, and then ground; Can also be the top surface, then the ground, the rear wall. 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.
Step 3: Find out 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!
Identify the key lines – parallel lines – acceptance lines – interspersed construction lines
“Wall cylinder” covert pre-acceptance – critical line analysis
“Ceiling” Covert Pre-Acceptance – Critical Line Analysis
“Ceiling” After covert acceptance – Critical Line Analysis
The wall is inspected at once
The top of the wall is covert before acceptance
After covert acceptance of the top of the wall
Step 4: Project instance preparation
Microsoft Project is a powerful and flexible project management tool that can be used to control simple or complex projects. (Software operation is very simple, it is recommended to search for video viewing in Baidu, it is important to bring in construction logic ideas.)

Pay attention to the implementation and adjustment of the correction plan
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 technology, management, strict quality control key points.
2. Adjust the schedule reasonably according to the on-site situation in the case of guaranteed total duration. Reasonable arrangement of different types of cross-construction before and after the plan
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.
(1) Enforce the completion point of each node and implement the reward and punishment system;
(2) Increase the intensity of quality inspection of the project, so that the problem is found in a timely manner to deal with, each team to follow up step by step, for the discovery of the problem to make rectification commitments, and within the commitment period to complete.
