Visa information is always called back? Send you a practical guide to the validity of the visaslip!

01. Visa list is the core of technical and economic work

Engineering visa refers to the supplementary agreement reached between the contracting parties in accordance with the contract agreement on compensation for expenses other than the contract price, extension of duration and compensation for losses caused by various reasons during the performance of the construction contract.

The theoretical types of changes: The visa of the contact list must be related to the change, there are usually design changes, other changes in the books.

•  
• The actual types of changes: change design (triage), change drawings, change process, change quote, change quantity, change unit price, variable material price, variable consumption, change loss, change mark, change ratio, change brand, change specification, change material, change rate, change cost, change site, change name, and so on.
•  
• Technical and economic core work: how to “define” changes in the actual construction process, rather than ambiguously, and solve the contradiction between “change and change” is the core work of the technical economy of contact single visas.
•  
• The core purpose of the change:“Additional” increases the cost of the project, eliminating, avoiding or reducing the risk of the cost of the project and the risk of settlement.

02. Visa list true effective follow 5 principles

The following articles must be available at the same time

• Conforms to national laws and regulations (including general and mandatory engineering norms, etc.);
• In line with the national pricing norms, provinces and cities in various regions of the pricing rules;
• conforms to the contract agreement (including the pricing basis of various agreements), the actual nature of the project itself;
• Conforms to and connects with the current situation of the state and various owners related to the project cost management (e.g. contract text, replacement system, process cost management, supervision, audit, audit, etc.);
• In line with the visa procedures, the stamp is complete.

03. What are the technical difficulties of a valid visa?

1. Is it included in the bid quote (including unit price and total price)?

Visas are generally involved in matters that are not foreseeable during the bidding phase, such as design changes required by Party A, replacement of main materials, increases and decreases in workload, delays in the duration of Party A’s reasons, and force majeure as stipulated in the contract or policy documents, etc., which require full analysis, tender quotation documents and drawings, whether they are hidden within the scope of the bid quotation, pay special attention to the preparation of the list and the description of the features of the list item.

For example, the common ground leveling thickness, list quote description:1:3 cement mortar to find a flat layer 30mm thick, then we do a good job of visa, covert information, evidence collection, can only do a good job of the visa beyond the part.

The other is to pay attention to whether it is a leak, whether this item is included in other items: such as wallpaper paste, scrape putty twice, paste wallpaper, the list is not oil back cover, quotation documents and drawings are not, we can try to apply for a visa.

2, is it a deeper design?

For a sub-item project drawings, if the actual construction method, process and party A provided by the original bid price drawings do not match, can be issued a technical approval form, with Party A clear specific changes, while the form of a visa to sign the additional price of the change (from our point of view, even if the contract is a fixed unit price contract, as long as the practice and the original drawings or specifications do not match the visa is still to be signed).

3, whether to inquire about the bid minutes commitment?

There are also some explanations in the bid commitment that can be used as a visa basis, especially the confirmation of the construction interface, whether it is the basis for increasing the amount and scope of the project, the preconditions for the duration of certain projects, and the prerequisites for the completion of certain projects.

Construction measures are also to avoid the scope of the project, scaffolding costs, vertical transport costs, the cost of secondary removal and so on.

4, is it a specification, standard, or owner technical clarification including content?

Norms, standards, or owner technical clarification including content, is currently a headache, the general visa basis is within these scopes, how to avoid this risk, we need on-site construction and drawings deepening process according to the actual situation on site changes.

Mainly to increase the necessary technical measures to strengthen (not measures), such as curtain box steel frame reinforcement, material changes on the brain, such as direct sunlight, gypsum board latex paint into aluminum plate.

5, is there a problem between the list, drawings, field three?

The description of the project characteristics is the essence of the construction process is missing, the site and the list, drawings do not match the situation is an opportunity, mainly to see if the site management personnel can seize, such as the wall tile of the original wall vertical, flat, square degree should cause the thickness of the wall brick paste layer changes, as the basis for the visa.

04. Risks to avoid on a valid visa list

1. Is it within the scope of risk included in the contract?

This should be clear about what risks the contract includes, before construction needs to be found out from the contract, visa all to avoid the scope of risk, fixed comprehensive unit price mainly from the material, construction process, fixed total price contract is more from the increase of the scope of work, work content and design changes to start.

2. Is it included in the (technical, organizational) measures fee?

The cost of the measures specified in the general project contract is covered. Visas in this area are generally difficult to obtain, and this aspect is generally taken to increase the scope of the project and change the design requirements to handle.

Therefore, the visa processing process to do everything possible to circumvent technical measures, to the scope of the special process outside the specification of the construction requirements close to have the opportunity to process additional costs of the visa.

3, is it a missed bid offer?

If the tender list provided by Party A is omitted, then the missing bid price is outside the contract price, it is natural to sign the certificate, the new project quantity list project its corresponding comprehensive unit price proposed by the contractor, confirmed by the contractor as the basis for settlement.

If, as the tenderer omits the outstanding report, according to the tender documents, it will generally be regarded as the tenderer’s concession or its price has been included in the comprehensive unit price of other projects, experienced owners will not give visas, how can we do, I think we can handle design changes to work around.

4, is it a bid offer?

Bid quotation concessions, generally speaking, will be calculated back to the comprehensive unit price, so that there will be future increases in all costs will be the same proportion of profits, I suggest that the profit as the total price concessions, do everything possible not to reverse the unit price, so that the project is generally negotiated bid items, we can talk about the total price concessions, that is, the total amount of profits we make, a one-time death, will avoid some risks.

5, is it actually happening?

The occurrence of liability events is the basis for the processing of visas, the occurrence of non-responsible events visas naturally can not be talked about, the actual occurrence must be to be processed, in the process of processing to do some amplification of the technical processing is also feasible.

No visa is actually not happening, we can sometimes handle, such as some other non-our reasons, causing us to complete the construction project damage redo, we may just repair, but we can handle redo;

6, is there a design change?

Design changes are liability events other than the contract price and generally require a visa (unless otherwise agreed in the contract).

To do such a visa is best to have the owner issued or approved the design change order, which requires that the change before the construction requires Party A to issue a change order, as a basis for the visa.

During the construction process, the general situation of the change order is handled by the construction worker, but for the wording in the change, etc. should be grasped by the pre-accounting personnel, while considering the combination of tender documents and contracts.

7, is the owner required?

The owner’s initiative to cause the responsibility of the event is very beneficial to the processing of visas, it can be said that at this time is the owner’s instructions and requirements of our, even in accordance with the requirements of the owner’s instructions to do, the processing of visas is generally logical.

But in the actual construction process, many owner instructions are oral, there is no basis, we need to issue in its oral instructions, before or in the implementation process, to its relevant personnel issued confirmation documents, so that there is evidence to rely on.

8, is the scope of work, interface division including content?

Whether it is a unit price contract or a fixed total price contract, the scope of work, work interface division including content and design changes are the best reasons for the visa, especially fixed total price contract, this visa needs to be handled in a timely manner, which is the contract price outside the inevitable increase and decrease.

9, whether to pack dry content?

Contract dry content we have no way to handle the visa, but we are all according to the drawing construction, if the material is A supply, then we are according to the drawing to Party A picking.

In the actual construction, often appear the actual material demand is greater than the amount of drawing design or the actual loss rate of A supply material is greater than the fixed loss, so to do a good job in the A supply of material visa.

05. Essential elements for improving the visa contact list

1, the main improvement of the 8 essential elements

• The cause factor
• Describe and clarify the facts, grounds and reasons for this contact list.
•  
• Nature elements
• Changes are mainly design changes (materials, plans, structures, etc.), changes in construction conditions (site and surrounding environment), schedule changes (deferred and pre-emption), and engineering project changes (construction content).
•  
• Scenario (drawing) features
• We must guide the determination of the scheme and list a series of reasons for the best solution for us (from specification, construction process, material properties, time, space, etc.).
•  
• The number of features
• Whether on the basis of drawings, or on the actual construction measurement on the site, it is required to have a logical and construction principle, detailed engineering volume calculation.
•  
• Cost elements
• According to the contract agreed unit price, sub-item price, material price, tender price, group price.
•  
• Cost elements
• After the price of each individual sub-purpose is determined, various expenses (various measures, management fees, material premiums, matching fees, fees, taxes) should be considered.
•  
• Time elements
• First, whether our visa negotiation is reported within the contract agreement validity period, which is a node problem that is easy to be ignored by project managers;
•  
• The resulting feature
• First, the visa contact list signed after an increase in cost or duration extension, our construction side according to the new program construction, and second, the visa contact list, can not be signed in time, so that the construction schedule time, quality, effect can not meet the design requirements, these consequences are not borne by us, and we also have the right to claim, these are best described in the visa contact list.

Complete the above 8 aspects to complete a complete visa contact form. (Instruction slip → drawings → Engineering quantity calculation → group price file → confirmation file) forms a very logical chain of evidence (complete stamps).

But this is not complete and strict enough, we also have to and material inspection, covert engineering inspection, completion map, completion information inspection of all information consistent, complete, can be considered a complete and strict economic benefits of the visa contact list. Only a complete and valid visa form is of practical significance to us.

06. It is worth noting where the visa is

1, wall stone maintenance issues, wall stone maintenance in the Beijing area is not considered, if you want this part of the money, we must go through the visa procedures.

2, scaffolding lease period, scaffolding lease date needs the owner to confirm, from the installation of pipe entry date to the completion of demolition, in addition to the visa should be marked as full scaffolding or inner wall scaffolding. Visas can also be repeated, such as the appearance of secondary facilities, the length of time to carry out visas.

3, lamp belt, from the quota understanding with the light transmission for the lamp belt, without the light film set lamp slot head.

4, cylinder stone dry hanging, cylinder stone dry hanging quota subhead has included angle steel base, this part of the actual construction can be considered without corner steel welding to use square tube visa, so that the use of sub-items can be used steel skeleton or accounted for a part of the cheap.

5, ground stone waxing, stone waxing and ground crystallization processing in the settlement audit process is mutually exclusive, but if there is no visa, the audit unit can not give this part of the money.

6, the cost of measures, for the measures to increase the cost of the project after the need for the project department through visas to fight, especially the follow-up to increase the project more projects.

07, visa case

1, to a project light steel keel fire barrier as a case

Project to increase the light steel keel fire barrier, because the contract for the total price package dry contract, the project department to take, find out a variety of excuses, first of all clearly not in my contract construction scope, and because these partition walls do not complete seriously affect my construction schedule, to us and Party A have caused losses, while showing that we do not want to build this difficult partition wall.

Based on the minutes of the meeting and the light steel keel construction atlas, we issued an increase in the scope of the project, the project quantity map and the specific node map, which quickly passed the approval of the engineering department and the general studio.

During the construction process, not only can do the project, should learn how to do the project well.

2, to a project bathroom steel frame partition wall as a case

First of all, according to the tender documents, the construction content is clearly not in our scope of work, at the same time we are relatively high (layer height 5900mm),design wall thickness (thickness 100mm),and there are doorfan installation, can not use bricks and blocks for wall separation works, by our proposed steel frame wall construction program.

In this way, we issued an increase in the scope of the project, the project volume map and specific node map, quickly passed the engineering department and the general studio of the audit and approval.

3, to a project dome steel frame as a case

After the establishment of the project, we will be in accordance with the drawings issued by Party A requirements for group price quotations.

How can we get the price up there? To find a good reason, we through the full study and analysis of drawings, decided to deepen the shape of processing, installation, fire-resistant coatings as the entry point to increase costs, increase the cost of special-shaped processing fees, high-altitude operations and high-altitude scaffolding measures, and set up a number of so that Party A and the agency can not clear the basis for shaped processing, increase our various construction difficulty requirements.

08, material sign-off

Stone and wood finishes are the signed materials that almost every project will encounter, so I’ll take the material sign-off for a project as an example.

To shape the material as the entry point, and split, the same variety of stone, used in different parts, different specifications, according to the splicing and thickness, we have to determine different prices, determine different material losses.

Wood finish, the most successful is to split, to the wood finish into lines quote, so that the unit price reflects not high but integrated wood finish price is high.

Analysis of the unit price of slicing stone:

Large-scale drawing of wood finishes:

Analysis of unit price of wood finishes:

The above several visa contact list, mainly in the development of ideas, in the project to seize some key points, special points to achieve some success.

Each project has its particularity, can you plan it well, only in-depth understanding of the actual situation on the ground, paper drawings for in-depth study, to find out the business point to achieve the goal.
