1、 Qualification requirements for construction
Although the laboratory decoration has its particularity, but the current laboratory construction is still in accordance with the construction industry qualification certificate provisions to clear the construction provisions!
So what are the problems in laboratory construction? The general mechanical and electrical engineering, environmental protection and installation of the laboratory are included! Therefore, in terms of qualification certificate, it is generally necessary to have electromechanical engineering installation qualification certificate, decoration design and decoration qualification, environmental protection qualification, fire protection qualification, class II pressure vessel construction qualification certificate, intelligent qualification, etc. If a new construction general contracting project is obtained, all kinds of qualification certificates of construction general contracting must be obtained.
2、 Specific contents of construction
Laboratory decoration is mainly for a part of the room, which generally includes decoration design, water supply and drainage, HVAC engineering, electrical equipment, intelligent system, gas path, sewage, organic waste gas treatment, laboratory furniture, etc.
The decoration design includes the ground leveling and epoxy floor construction, partition wall construction, ceiling decoration construction, window and door construction, curtain cloth construction, equipment foundation construction, etc;
Water supply and drainage includes water supply and drainage, drainage pipeline, purified water, etc;
HVAC engineering includes ventilation duct, central air conditioning pipeline, cleaning pipeline, air conditioning water pipeline, installation of machine equipment, air conditioning duct installation, etc;
Electrical equipment includes cable and wire construction, lighting lamp power socket construction, power distribution cabinet construction, etc;
The contents of intelligent system include the construction of magnetic induction electronic devices, wiring, server and host room according to the system included in the intelligent system;
The gas path is mainly the installation of various gas pipelines, gas tanks and gate valves;
Sewage mainly includes the construction of sewage station building and sewage machinery and equipment;
Laboratory furniture includes a variety of laboratory furniture, test bench, laboratory cabinet, ventilation and cooling equipment, water supply and drainage equipment, gas path machinery and equipment, and safety level machinery and equipment.
3、 Construction steps
In fact, the construction steps of all new projects are not very different from those of other mechanical and electrical engineering installation. From the system, that is, the installation of mechanical and electrical engineering pipeline, the installation of machinery and equipment and the installation of decoration design, the overall construction is the organic combination of these three parts, which is very different from the integration of mechanical and electrical engineering pipeline and decoration design and installation Decoration design method will stipulate different construction steps.
The basic step is to level the road surface first, and then to install the electrical and mechanical engineering supervisor. The construction can be carried out before and after the two processes. Only when the floor leveling is carried out, the staff can not carry out construction in the construction area. Therefore, it depends on the allocation of time and scheme, and the purchase of various large and medium-sized machinery and equipment can be carried out smoothly.
Many pipelines through the partition wall must do a good job in the embedded hole, for some of the partition wall can be done first, in the middle and later period in the decoration of the ceiling pipe can be done, but must be decorated ceiling interior space is sufficient, otherwise it can not be constructed.
Some of the pipelines with higher cleanliness level are better to wait for the construction with heavy dust in the room to prevent environmental pollution, or take protective measures in advance.
After the construction of the main pipe and partition wall, the foundation can be in accordance with the riser and decoration ceiling. At this time, the key machinery and equipment can also be delivered. At the same time, the installation of machinery and equipment and the lifting of machinery and equipment in the decorated ceiling can be done. There will be more areas in the middle that must be harmonious. After all, the interior space in the decorated ceiling is relatively limited. If all kinds of risers are not available in advance If there is a good arrangement or BIM impact inspection, it is very easy to cause a variety of cross type problems. Therefore, it is better to report the work daily, communicate harmoniously, and reduce the occurrence and repair of problems.
