Whether the HVAC professional subcontracting includes civil engineering content

Contain. There are many professional subcontracts, such as steel structure, installation (water and electricity, HVAC, fire protection, weak electricity, strong electricity, etc.), information, outdoor greening, foundation, curtain wall, decoration, construction and other specialties.

1.Industry monopoly projects: fire protection, gas, tap water pressurization, high-voltage side of the distribution room.

2.Special specialty projects: operating rooms, vaults, special equipment, etc.

3.Professional projects: grid, steel structure, curtain wall, precipitation, wall protection, piling, weak current monitoring, elevator, etc.

At present, the super-grade construction enterprises have some professional companies with some projects in the third item, and the owners can carry out professional subcontracting according to whether the qualifications of the contracting enterprises are included and the scope of the contract projects. The first two items are best entrusted to the enterprises directly under the territory or management department.

1.Check the bill of quantities to see if the amount of the civil part is done according to the drawings, and if so, it is deemed that the total price includes the civil part. If it is not done, see if there is such a sentence in the tender - the engineering quantity includes all the contents that constitute the installation of the equipment, that is, the comprehensive unit price of the sub-item includes the cost of the civil works.

If there is, it is also considered to be included, and if not, a visa can be requested.

2.Equipment base can be visa. 1. The drawings were not original, 2. The HVAC profession needs to increase the amount of this project, which will inevitably increase the cost and construction period.

The project not included in the drawings can be discussed with the supervisor for a visa, if the supervisor does not agree, you can use the construction as a reason.

There are 5 major departments of civil engineering, construction, engineering management, equipment engineering, and information engineering, and there are many specific majors!

The subcontractor subcontracts the professional project or labor service to the subcontractor who does not have the corresponding qualifications;

If there is no agreement in the general construction contract, and without the approval of the construction unit, the employer of the subcontracted project subcontracts part of the professional projects in the contracted project to others;

The professional project subcontractor implements the subcontract again;

If the subcontracted project contractor does not subcontract the project it has contracted, and the project leader, technical leader, project accounting leader, quality management personnel and safety management personnel of the project management organization set up at the construction site are not the personnel of the project contractor's own unit, it shall be deemed to allow others to contract the project in the name of the enterprise;

Transfer, lend the qualification certificate of the enterprise or otherwise allow others to contract the project in the name of the enterprise.

Civil engineering.

Construction project management.

Plant engineering. Information Engineering.

5 major departments, more specific majors!

The first question mark: except for the construction of the main part of the building, the others are not necessarily done by themselves, as long as the tendering party agrees;

The second question mark: you can find a third party to do it, that is, subcontracting;

The third question mark: if you find a third party, it must be that the general contractor will make relevant estimates or inquiries when bidding. This depends on the experience and ability of the general contractor, the capable general contractor can accurately estimate the subcontract content, and then carry out subcontract bidding after they win the bid, which is based on the actual construction schedule and schedule, which can be before the construction of the building after winning the bid, or during the construction of the building, or after the construction of the building; If the general contracting capacity is limited, then in order to ensure that the cost is not controllable after winning the bid, they will ask the intended subcontractor to inquire in advance when bidding;

The last question mark: the general contractor looking for a third party does not necessarily use bidding, the key depends on the nature of the project, the amount of project investment and supervision and Party A's requirements for the selection of the first contractor, the general contractor of the general project can directly determine the subcontractor, and the large-scale project may require each subcontracting link to follow the bidding method for bidding.

Understand the construction content, construction period and organizational structure of the general contracting project department, obtain the best and bidding qualifications, carry out the best according to the technical quality and construction period requirements related to the HVAC of the project, maintain good customer relations, and strive to obtain the contract.

Different construction projects, in the early stage of design has been planned, on how to manage the construction of the contracted project, considering the management technology and cost, project quality and construction period, will choose whether to be the general contracting mode or the management of the general contracting, generally will use the building structure construction unit as the general contractor, mechanical and electrical general contracting or subcontracting, mechanical and electrical general contracting can be a unit, can also be a multi-professional unit subcontracting. For example, if you do electrical, it belongs to electrical subcontracting, directly under the management of mechanical and electrical general contractor, and the mechanical and electrical general contractor is a branch of the general contractor of the project, of course, such as China Construction Group, which has the strength to do construction and mechanical and electrical, landscaping and curtain wall, etc., he does not have to subcontract the sub-project out.

These general contracting and subcontracting relationships can be combined in various ways.

According to what you said, the project has been contracted by the civil engineering unit, including mechanical and electrical, and it needs to subcontract the mechanical and electrical specialties, then your company will have the opportunity to bid, pay attention to the bidding announcement of the general contractor, whether your company's qualifications meet the bidding requirements, whether the personnel, capital and technical strength are competent, will play an important role in the bidding results, the domestic strength is strong, everyone has the ability to do the unit, how to win the bid, it depends on the ......, construction period, technology, reputation and so on

Engineering industry, the general contractor won the bid, no matter before and after, it must have accumulated the so-called third party of various professions, not afraid of no one to do, fierce competition, it depends on whether your company has the core competitiveness, the relationship is also a kind of, just entered the industry, make full use of the resources in the industry, big fish eat small fish, small fish eat shrimp, big fish do not want to eat shrimp, you are willing to eat there is a chance, this is the reason, Yapu Shangpin "for your reference, thank you. Look at Shangqi!

Treats, meals, gifts, relationships

Equipment, OK, or how to teach the built environment and equipment engineering.

Strictly speaking, the HVAC profession belongs to the construction category. Under the first-level discipline of civil engineering, there are six second-level disciplines, and heating, gas, ventilation and air-conditioning engineering (called building environment and architectural engineering at the undergraduate level) belongs to one of these six second-level disciplines. The above is for reference only.

3.Construction Equipment Class 4Engineering management.

It belongs to the category of construction equipment, and there is nothing else to discuss.

Specifically, it belongs to the category of construction equipment, and in a broad sense, it also belongs to the category of municipal engineering.

1. Different types.

Professional project subcontracting refers to the activities of the general contractor of the construction project to contract the professional projects with strong professionalism in the contracted project to other construction industries with corresponding qualifications in accordance with the provisions of the general contracting contract or with the permission of the construction unit.

The designated subcontracted work is the work that the contractor is unable to complete and does not belong to the scope of the work that the contractor must complete as agreed in the contract, that is, the contractor does not amortize the overhead costs, management fees, profits and taxes when bidding for the work.

2. The management content is different.

Under the condition of professional subcontracting, the duties performed by the general contractor are mainly to supervise and inspect the construction process, construction materials, and quality status of materials and equipment of professional subcontracting projects (sub-items), that is, compliance management; Since the appointed subcontractor is ultimately selected by the owner and the payment of the work is incurred from the provisional amount, a clause protecting the designated subcontractor is included in the conditions of the contract.

3. The scope of responsibility is different.

Under the condition of professional project subcontracting, the general subcontractor and the general contractor shall be responsible to the employer for the subcontracted project and its quality; The Contractor shall not be liable for any claim or action resulting from any breach by the Appointed Subcontractor resulting in damage to the Owner or a third party, except as a result of the Contractor issuing erroneous instructions to the Appointed Subcontractor.

Professional subcontracting refers to professional engineering subcontracting;

Professional project subcontracting refers to the act of the general contractor of a construction project contracting part of the contracted project to a subcontractor with corresponding qualifications in accordance with the provisions of the general contracting contract or with the permission of the construction unit.

In FIDIC contracts, the appointment of subcontracting is an important way of awarding contracts, which is widely used internationally. It is also common in domestic real estate projects, but it is still argued in the national construction law system that the appointment of subcontractors by the owner is not allowed.

A designated subcontractor is a special subcontractor who is designated, selected, and selected by the owner (or engineer) to complete a specific job content and sign a subcontract with the contractor. The terms of the contract stipulate that the owner has the right to contract the construction tasks of part of the project or the work content involving the provision of materials, equipment, services and other work to the designated subcontractor for implementation. Since the designated subcontractor is to sign a subcontract with the contractor, it is in the same position as the general subcontractor in terms of contractual relationship and management relationship, and the supervision and coordination of its construction process are included in the management of the contractor.

The specified subcontracted work content may include the construction of part of the project; **Goods, materials and equipment required for the project; Devise; Provision of technical services, etc.

Professional subcontracting - such as water supply and drainage majors, electrical specialties, fire protection specialties, HVAC specialties. The boss can assign these specialties to someone to contract, that is, appoint a subcontractor.

Professional subcontracting includes steel structure, installation (water and electricity, HVAC, fire protection, weak electricity, strong electricity, etc.), information, outdoor greening, foundation, curtain wall, decoration, construction and other specialties.

Professional subcontracting refers to the activities of the construction unit or the professional subcontractor (both of which can be the employer of labor operations) to contract the labor operations of their contracted projects to labor subcontractors to complete the activities. That is to say: after the construction unit A contracts the project, it buys the materials by itself, and then asks the labor unit B to be responsible for finding workers to carry out the construction, but the construction management is still organized by the unit A.

Professional subcontracting refers to signing a subcontract with the contractor within the scope of one's own professional contracting qualifications, which is a contract for the subcontractor. The reason why it is called subcontracting is in terms of the subject matter.

Tong Chang does not belong! The current laws and regulations specify that the main project shall not be subcontracted.

Hello, these clauses, only from the literal point of view, are obviously inclined to the interests of the employer, in terms of the content of the clauses alone, the first clause belongs to the situation that may constitute a change of circumstances, which can lead to the termination or change of the contract. Other clauses can also be seen to favor the interests of the employer, so the contractor is required to exercise a high degree of care to prevent the occurrence of breach of contract.

As for whether it is considered an overlord clause, it depends on how to understand it, many of the breach of contract agreed in the contract, as long as the contractor strictly manages, it can still be avoided, if there is room for negotiation, it is best to modify the terms of the contract, if the other party is strong, can not be modified, it can only be to try to avoid the occurrence of breach of contract.

It belongs to the installation work.

Civil works include earthworks, basic structures, roofing, decoration and decoration works.

Installation includes: water supply, drainage, heating, electrical engineering, ventilation and air conditioning engineering, including the installation and commissioning of equipment in these three categories.

1.Electrical engineering - strong current system (power, lighting) weak current system (telecommunications, television, alarm, intelligence, etc.);

2.ventilation and heating system (ventilation and exhaust ventilation, smoke prevention and exhaust);

3.water supply and drainage system (domestic water, production water, fire water, sewage, waste water, rainwater, etc.);

4.fire protection systems;

5.mechanical equipment systems;

6.gas systems, etc.
