What Is a Duration Gap?

Construction period refers to the time limit for the completion of a project. Construction period is one of the important accounting indicators of construction enterprises. The length of the construction period directly affects the economic benefits of the construction enterprises, and is related to the completion of the plan to use the additional production capacity of the national economy and the exertion of economic benefits.

The time elapsed from the start of construction to completion of all the contents specified in the contract, and the time to reach the completion acceptance standard, is expressed in days. Construction period is one of the important accounting indicators of construction enterprises. The length of the construction period directly affects the economic benefits of the construction enterprises, and is related to the completion of the plan to use the additional production capacity of the national economy and the exertion of economic benefits.

The construction period refers to the time that elapses between the start of construction of a project or a single project and its completion. It is an indicator that reflects the effect of investment from the perspective of construction speed. The calculation of the construction period is generally calculated by subtracting the start-up year from the start-up month of a construction project or a single project. Is the duration of work, the length of time.

For example, the construction period is one week, which means that the time required to work is one week, which refers to the working time. Refers to the time elapsed from the commencement of the project to completion of all the provisions of the contract and the completion acceptance criteria, expressed in days.

The fixed-term quota refers to the average number of standard days required to complete a unit (or group) project under certain production technology and natural conditions. Including the construction period quota and construction period quota two levels. It is a fixed number of days for the construction period specified for various projects.

The construction period refers to the total amount of time spent in the construction process of a construction project or an independent single project. Usually expressed in months or days. It starts from the beginning of construction and stops when it is fully completed and put into production or delivery. However, it does not include the delays in stopping (slowing down) construction due to decision errors. The construction period generally refers to the time that elapses between the start of a single project or a unit project and its completion. The construction period is part of the construction period. For example, the construction period of a unit project refers to the total number of valid days from the start of construction to completion of all design content of the contracted project and meeting the national acceptance criteria.

The construction period quota is based on the relevant national construction engineering quality inspection and evaluation standards for construction and acceptance specifications, combined with various construction conditions, and based on the principles of average, economical and reasonable. The basis for assessing the construction period is an important basis for the preparation of the bidding base, the bidding tender and the signing of a construction and installation project contract. The construction period quota is the basis for evaluating the construction speed of the project, compiling the construction plan, signing the contract, and evaluating the whole excellent project. The construction period is divided into calendar period and effective period. The difference between the two is that the former does not deduct statutory holidays and rest days, while the latter does.

Regardless of the construction unit or the construction unit, the construction of the project is pursuing low cost, high quality and short construction period. Reasonable speed

In the control of the schedule, we will make full use of the various resources of the enterprise and take various practical measures and methods to ensure that the project is completed as scheduled. According to the construction characteristics of the project, in order to ensure the implementation of the planned construction period, the control is divided into three stages: basic construction, main construction, and decoration construction, and the overall plan goals are guaranteed on the premise of ensuring that the stage goals are achieved.

The main method of schedule control

1.1 Administrative methods:

The project manager department makes proper use of administrative methods, issues schedule instructions, and uses incentives (reward, punishment, praise, criticism, etc.), supervision, and supervision to control progress. When using administrative methods, we must also promote scientificity and prevent subjective, arbitrary, and one-sided blind command.

1.2 Economic method:

As the general contractor of the project, make more use of economically controlled

Speeding up the construction progress and shortening the construction period is not only a requirement for the construction unit, but also a necessary condition to meet the owner's requirements, or an effective way for the construction unit to improve economic and social benefits. The scientific and reasonable arrangement of work plans and schedules for effective implementation of management and necessary inputs were explored.

Construction period

Postponement of construction period and claims in 2008 (case)

The owner and the construction unit have signed a construction contract for a construction project. The contract stipulates that during the construction process, if the owner's reasons cause a nest work, the manual nest work fee and the machinery shutdown fee can be based on the working day fee and the shift fee. 50% of settlement payments. The owner also signed a supervision contract for the construction stage with the supervision unit. The contract stipulates that the supervision engineer can directly apply for a visa, approve the extension of the construction period within 5 days, and claim for individual expenses within 5,000 yuan. The project is carried out according to the following network plan. The key line is AEHIJ. During the planning of the hospitality, the following situations occurred, affecting some work temporarily suspended. (Due to different reasons, the same work is not at the same time)

1. Due to the owner's failure to supply the materials in time, E was delayed by 3 days, G was delayed by 2 days, and H was delayed by 3 days.

2. E is delayed by 2 days and G is delayed by 2 days due to mechanical troubleshooting.

3. Due to the owner's request for a design change, F was delayed for 3 days.

4. Due to the power outage on the public network, F is delayed by 1 day and I is delayed by 1 day.

Impact on project duration

First of all, a concept should be clarified. "Nails" is a derogatory term and cannot be used casually. In the face of apparently unreasonable demolition conditions, those who refuse to relocate cannot be named "nail households." Only those who are unsatisfied due to unreasonable requirements and deliberately rely on immobility, so that the relevant parties can satisfy their unreasonable conditions, are they really "nail nailers."

Due to the nail household problem, the construction period is delayed, the size of the losses to the developers and the owners, and what losses will be caused depends on the length of the delay and the specific process and circumstances. For a long time, it is not just the losses of developers and owners that have a greater impact. It's asking developers and owners of losses, so I won't say anything about this).

Direct economic losses caused by developers

Direct economic losses to developers due to "nail households":

1. Occupation of funds and loss of loan interest;

2. Compensation to the builder for failing to start construction on schedule;

3. Compensation for the owner of the purchased house because the house cannot be delivered on time;

4, encountered situations such as the current economic downturn, the loss of housing prices.

What has been said above is major and obvious, and there are many other economic losses such as capital investment benefits, as well as damage to corporate image and reputation.

Direct economic loss to the owner

Direct economic losses to owners due to "nail households":

1. A lot of home buyers are demolished households, and the rent of temporary housing is lost due to extension of stay;

2. Economic losses or even business opportunities caused by the urgent need of housing (some of which are purchased for business purposes) and failure to use it as scheduled;

3. Loss of house prices due to the economic situation, especially speculators (although they are not recommended, they exist after all, and there are a lot of them);

4. For owners who have made wedding arrangements according to the check-in date, not only must the wedding be postponed, but those who have already reserved a banquet, but also have to refund the banquet due to the extension of stay, and make compensation for breach of contract.

There are also some hidden economic losses. It is not easy to explain in a few words, so I will not talk about them.

Do not understand the construction economy, just talk about it, as a brick to attract jade, for reference only, and please correct me.
