To have a project that meets technical and safety standards according to state regulations, businesses need to clearly understand each step. factory construction process standard – correct. The following is the most detailed information to help businesses build quickly and correctly.
1. Factory design process
After receiving information and requests from customers, the engineering team will create the most complete and detailed design.
1.1. Survey and propose construction plans
The first step to take is to survey and come up with construction plans. The construction unit will come to survey the location and premises and propose design options. After that, the team of architects and technicians will propose solutions for technology and technical infrastructure so that the construction can be carried out appropriately.
The construction unit will offer the most reasonable architectural options for projects that require high design and architecture such as office areas, security areas, etc. Then, the construction team will design The designer will also consider and optimize plans for environmental protection and fire prevention according to regulations of the State, industrial parks or industrial clusters where the factory construction project is carried out.
Finally, propose plans for the foundation structure to suit the geology in the factory construction area and set out the main standards and regulations to be applied when designing the house. workshop.
1.2. Design preliminary drawings for the factory
After surveying and coming up with construction plans, architects and engineers will concretize the ideas with specific drawings of the entire planning site, each item's site plan and coordination plan. 3D scene of the project. These drawings will help investors visualize the project more easily and accurately after completion.
Depending on the production field, technology line and scale of each factory, the floor design is also different. Drawings need to clearly show the items that need to be built in the project, density, construction boundaries, internal road system, tree density, etc. In addition, drawings of the fire protection system and The escape system is also extremely important.
1.3. Prepare detailed drawings and estimate construction costs
The preliminary drawing will be the basis for the investor and the construction unit to discuss together to come to a final agreement on the construction plan. After that, construction drawings will be completed by a team of engineers and architects.
At this stage, the drawings will specifically show all construction items, from architectural structural details to foundation structure plans, prefabricated steel frame drawings, connection nodes, specifications. for materials, M&E drawings, fire protection and escape systems for each of the following items:
- Factory area
- Storehouse
- Office area
- Dining room, canteen, rest area for officials and employees
- Underground tank
- Power station
- Garage, security house
- Gates, fence systems...
Along with completing detailed construction drawings, the investor also needs to apply for a construction permit and fire protection permit. As for the contractor, the construction team will create a construction budget estimate, each task and the specific amount of work to be done for all items. The set of documents including construction drawings and cost estimate table will be the basis for acceptance of construction work and the amount of work completed later.
2. Factory construction process
After completing the factory design, the construction unit will begin the factory construction steps.
2.1. Receive and preserve factory construction materials
Before proceeding with the steps in the factory construction process, the construction unit needs to receive materials in accordance with the quantity and quality required in the construction estimate. For example: quantity of steel, corrugated iron, bricks, cement, etc. Because the amount of materials and supplies used for factory construction is very large, it is very possible that the quantity delivered is not accurate and the type is incorrect. Materials are not consistent,... especially small bolts and screws.
In addition to careful inspection when receiving materials, construction units also need to ensure that materials are transported to the warehouse and stored carefully. Materials must not be worn out, damaged, or rusted before construction. Degraded material quality will affect the quality of the entire project.
2.2. Factory floor construction
Factory floor construction is an important and indispensable step. Because the foundation will affect the durability of the entire factory. Therefore, it is necessary to follow the complete factory construction process with the following steps:
- Step 1: Level the ground. Depending on the existing ground condition at the construction site, the contractor will deploy the leveling process accordingly.
- Step 2: Locate the heart axis. This is an extremely important job because the center axis position is the location of the column foundations constructed based on the drawings.
- Step 3: Dig the fence foundation. Because the factory has a very large area, the surrounding fence system is also very high and long. Therefore, it needs a solid foundation to stand firm.
- Step 4: Construction of foundation and stirrups. Making the foundation and driving piles will be based on the center axis location determined in step 2. Factory foundations are usually made of reinforced concrete with a single foundation or pile foundation design.
- Step 5: Compact the ground. After completing the foundation, the ground will be leveled and compacted to reach the density required in the design.
- Step 6: Roll the stone floor for the workshop. The thickness and compactness of the stone foundation layer also need to comply with the requirements in the design.
- Step 7: Construction of the workshop floor. After completing the above 6 steps, the construction unit will proceed to make reinforcement and pour concrete for the factory floor.
2.3. Construction of factory steel frame
The steel frame is an extremely important part, considered the backbone of the factory. This is one of the most important steps in the factory construction process. Therefore, the construction contractor must ensure the solidity, accuracy, and strength of the steel frame. To increase accuracy when installing steel frames, construction units will need to use modern measuring equipment such as theodolite, laser projector...
The factory steel frame includes 2 main parts:
- Installing iron frames and steel columns: Iron frames and steel columns will be pre-processed at the factory, then transported to the construction site. Depending on the site, the construction unit will install the frame and columns from the middle and then the two gables or from one gable inward.
- Install purlins and braces: After the iron frame and steel columns have been installed, the construction team will install a bracing system to ensure stability outside the frame plane and a purlin system to increase the stability of the steel frame and support the slab. roofing. This entire system needs to ensure accuracy and not move so that the next steps can be implemented properly.
2.4. Roof construction for the factory
After the steel frame has been assembled, the construction unit will proceed with constructing the roof for the factory. Like the steel frame system, roofing the first corrugated iron sheet also requires extremely high precision because it is the landmark for the subsequent corrugated iron sheets. After completing the roof, the corrugated iron sheets must meet the requirements: the overlapping points of the corrugated iron sheets are always in a straight line and perpendicular to the purlins.
In addition to correctly constructing the roofing, the contractor also needs to consider heat protection plans for the factory roof. To protect against heat, the roof will be layered with an additional layer of insulating cotton, helping to limit hot and cold air from the outside environment from penetrating inside the production area. The insulation cotton layer also needs to ensure straight joints, no folds or double shrinkage, and the underside is flat and not wrinkled.
2.5. Construction of surrounding walls and walls inside the factory
The exterior and interior walls of the factory can be built with materials such as corrugated iron, bricks, etc. This stage needs to ensure compatibility with the design and the frame reinforcement in the factory construction process.
Although it does not require as high a level of precision as installing a corrugated iron roof, the construction of exterior and interior walls in the factory must take into account safety measures: fireproof, windproof, dustproof... in a good way. best. Partitions can be made from fireproof and heat-insulating materials such as Samrtboard, Gywall plasterboard, etc.
After completing the erection of partitions and walls, the construction unit will proceed to install all kinds of doors, windows, ventilation doors, etc. After completion, the technical team needs to check once again. bolts, joints between corrugated iron sheets, gaps in door panels, etc. to avoid future leaks and splashes of water when it rains.
2.6. Construction of factory infrastructure
Construction of infrastructure system around the factory includes: drainage ditch system, access road, yard, warehouse, yard... The above infrastructure items are to ensure the transportation of goods and production activities. , working at the factory takes place most smoothly.
2.7. Construction of factory technical systems
In the next step of the factory construction process, the construction unit will construct technical systems for the factory such as: Electricity system, water system, drainage system, waste treatment system, fire prevention system. Fire fighting, communication systems, etc. These technical systems will ensure the factory operates smoothly and most effectively.
2.8. Complete the factory and install equipment
Next will be the stage of completing the factory and installing equipment, machinery, and final items. The technician team will also check again the connections, bolts, and screws in the factory to see if there are any problems. Once everything has been installed correctly, the construction unit will put the equipment and production lines in the correct position as per the design.
2.9. Clean and put into use
After completing the above steps, the construction team will clean the entire factory area one last time before putting it into operation and use. After ensuring everything has been installed correctly, without any technical errors, the construction unit will hand over the project to the investor.
In addition to cleaning and inspection as soon as it is completed, the contractor must also carry out warranty, maintenance, and regular maintenance work for the project. This will ensure the project operates most effectively and most persistently over time.
