Elevator as a vertical means of transport, and people’s daily life are inseparable. At the same time, the elevator is also an important category of government procurement, almost every day more than ten projects for public tender. How to purchase the elevator, in order to achieve both time and effort, but also value for money, from disputes, is a procurement and agents need to consider the issue. In fact, in order to meet the above requirements, only need to pay attention to some small details of the procurement process. In this issue, we will follow the procurement process to introduce ten details.
First, the elevator type to determine
During the planning period of the building, the use of the building should be clarified because the type of elevator used varies considerably depending on the buildings of hotels, office buildings, hospitals, residential or industrial and mining enterprises, and, once determined, It is very troublesome to change. After determining the use of the building, according to its construction area, floor (height), access to personnel flow, the elevator where the location of the building and other factors to make passenger flow analysis in order to determine the elevator speed (minimum speed to meet the requirements of fire forced landing), load (Large engine room, small room, no room), traction machine type (traditional turbine vortex and new permanent magnet synchronous).
Second, planning approval after the start of procurement
Procurement time It is recommended to start purchasing after planning approval. In the elevator type, speed, load, the number of stations, stop the number of stations, the total length of the trip, etc., can be commissioned by the architectural design department design blueprint, and the elevator building (mainly elevator shaft) part of the design department is usually professional Elevator manufacturers to provide the same type of standard civil construction drawings, combined with the building elevator shafts different structures such as brick structure, concrete structure, brick structure or steel structure drawing drawings. This size to consider the general, to meet the needs of manufacturers in general. However, different elevator manufacturers of the shaft design size, room and pit requirements are still different, if the advance to determine the manufacturers, according to the selected manufacturers of drawings designed to reduce the use of space waste, but also reduce the trouble of future construction. If the shaft is large, waste area; if the shaft is small, some manufacturers simply can not meet, it is necessary to non-standard production, increase a lot of cost.
Third, a reasonable choice of manufacturers and brands
Elevator manufacturers and brands in the world eight brands also have grades of points, there are the first legion and the Second Army said. Domestic elevator business is also a lot. The elevator is also a penny. You can according to their own budget and project positioning to select the same level of the unit tender. But also a large area of choice, and ultimately according to the degree of difference and then determine which grade. Elevators also have dealers and agents, they will be high prices, but the strength can be advanced. Usually choose manufacturers, so that quality is guaranteed, the service can find the root, but the payment conditions are more harsh. Industry practice is required to have a prepayment, delivery before the full amount or basic full amount. Elevator factory should be necessary business license, elevator production license, its construction sector construction enterprises grade qualification, installation safety certificate and other supporting documents.
Fourth, the interface to facilitate the transfer
Interface installation Elevator installation and the total package construction units (civil and installation), fire units, weak units are closely related to each other’s interface to be clear, the construction process to do the transfer.
Fifth, due to the need to select the elevator function
Each elevator factory has an elevator function table, the purchasing staff to understand its function. Some functions are mandatory, they can not fall. Some features are essential to the elevator, no election will have. Some features are auxiliary, not a must, you can choose. According to the project positioning selection function. The more features, the higher the price, in fact, not necessarily practical. Especially the barrier-free elevator function, residential projects, there is no mandatory requirements in the completion of the acceptance, the usual practice is not to be considered, for the stretcher elevator, the design specification has a mandatory requirement. For public projects, accessibility is considered complete. Elevator button arrangement, to consider the convenience, beautiful, but also consider the people and foreigners are sensitive to some figures, 13,14 and other letters instead. Tender requirements of the elevator manufacturers to offer a variety of options for reference when the standard selection.
Six, clear price to avoid disputes
The total price of the elevator project should include all the equipment prices, transportation costs, customs (into the ladder), insurance, installation fees, commissioning fees and manufacturers commitment to the owner of pre-sale, after-sales warranty and other related costs, but here need to explain, The construction department to the owners of the delivery has been installed acceptance, and qualified elevator, some late costs should be borne by the owners, such as elevator registration fee, installation inspection fee, fire (equipment) inspection fees, elevator annual inspection fees. The above costs, both supply and demand should be implemented as far as possible in the contract, in the form of clear the responsibility of both sides is the best way to avoid disputes. Tender requirements of the elevator manufacturers reported that the price of damaged parts and maintenance costs, this department costs related to the future use of the cost of operation, the property company is more concerned about.
Seven, the overall planning delivery time
Owners for their own building construction progress, may require the production of elevator manufacturers a clear date of supply, and now the general manufacturers need to supply two and a half months to four months, and the general building elevator equipment approach is best in the building has been capped, It is necessary to dismantle the outdoor tower crane before the appropriate, if the arrival of this before, is bound to occur storage and storage problems, and after this will appear twice the lifting, handling and other costs. Usually the elevator factory will have a certain period of free storage period, more than this time not delivery, the factory will receive a fee.
Eight, a good elevator to install three links
A good elevator, to control the following three main links (also known as three stages).
First of all elevator equipment product quality, which requires the elevator manufacturer of its production quality of the protection of the elevator is a special equipment, with production certificate of production quality is usually not a big problem, but the durability, stability will be difference.
Second, pay attention to the level of installation and commissioning process, the installation quality is very important, each elevator factory installation team are their own or long-term cooperation, but also assessment, commissioning are generally arranged by the elevator factory responsible person.
Third, after-sales service, and now the elevator is sold after the professional maintenance team is responsible for the elevator factory and the property company signed a maintenance contract, which ensures the continuity of the elevator factory work. Maintenance and management of the rational and timely, to ensure the quality of the use of the elevator. So the country as early as the early 90s by the Ministry of Construction issued a red tape, clearly stipulates that the elevator products by the manufacturer “through-train” service, that is, the elevator manufacturers to produce their own elevator equipment warranty, installation commissioning, maintenance And so on.
Nine, elevator acceptance can not be sloppy
Elevator is a special equipment, the State Bureau of Technical Supervision has acceptance procedures, but they are usually responsible for security, acceptance is also fly. So the owners and supervision units, to strictly out of the box acceptance, process monitoring, hidden acceptance, functional acceptance and so on. Must be in accordance with the elevator acceptance criteria and the functions identified in the contract one by one acceptance, an elevator an elevator acceptance.
10, hand control elevator safety
Elevator installation and commissioning is completed, the internal acceptance is completed, with the use of conditions. According to regulations, the elevator is not allowed to use the technical supervision bureau is not allowed to use, but usually this time the elevator has been removed, the total package unit other work is not completed, need to use the indoor elevator. Elevator units and the total package unit signed an agreement, the elevator unit arrangements for people to open the elevator, the total package unit according to the requirements of the elevator unit to use the elevator and bear the cost. After the completion of the project, do a comprehensive inspection and maintenance. After the completion of the project as a whole, the elevator company transferred to the maintenance unit, the total package transferred to the property company management.
