mechanical and electrical engineering is an important part of building engineering, mainly including water supply and drainage systems, power supply systems, air conditioning and ventilation systems, weak electrical systems, fire-fighting systems and intelligent systems. the quality of electromechanical engineering directly affects the overall quality of the building project, including the operational effect, energy saving and the practicality of the building when it is really put into use.
the commissioning of electromechanical equipment is the basis for putting electromechanical equipment into use and determines the basic service life of the equipment. good commissioning of electromechanical equipment will result in solid and stable conditions for benign operation. therefore, the use of various technical training, technical measures, scientific and reasonable commissioning of electromechanical equipment is fundamental to achieving safe production, improving the economic efficiency of business management and ensuring the safe and stable operation of equipment.
noa acts as a third party for owners to test, inspect and evaluate the main building structure of civil, industrial and public buildings to determine their safety, suitability, durability and reliability. through testing of key building materials and expert visits to assess the condition of all aspects of the building, facility or property, ensuring that the building involved complies with relevant local health and safety and environmental regulations, providing the owner with findings on the basic condition of the target facility/property, giving a list of defects/non-conformities and recommendations for rectification of the defects and non-conformities found, and providing a reliable basis for the client's acquisition/ lease/hold the building to provide reliable technical support.
noa provides a supplier technical evaluation service that covers, but is not limited to:
1. tendering stage
clarification of the commissioning requirements of the tender technical documents.
2.design phase
review the construction drawings, determine the owner's requirements for the project (opr), the basic principles of design (bod), develop the commissioning work plan, conduct commissioning design review when the construction drawings are completed, and incorporate the commissioning requirements into the construction documents.
3.construction phase
reviewing the submissions of the contractors of the commissioned systems according to the final construction drawings, verifying the installation of the commissioned systems, verifying the operational performance of the systems, preparing targeted commissioning plans and operation management manuals of the commissioned systems, and verifying the completion of operation management training.
4. commissioning phase
technical handover of commissioning work and supervision of the implementation of the commissioning programme. commissioning verification of the electrical, hvac, water supply and drainage, building automation, lighting, domestic hot water and other systems after the project equipment has been delivered to ensure that the actual installed systems meet the design and acceptance standards.
5. handover stage
transfer of drawings and information, and training of equipment operation personnel after the project is put into use, so that operation and maintenance personnel understand the owner's requirements for the project and the design requirements, so that they can do a better job in operation and maintenance.
what is the scope of building mechanical and electrical engineering?
it mainly includes six aspects: water supply and drainage system, power supply system, air conditioning and ventilation system, weak electrical system, fire protection system and intelligent system.
what are the common technical problems in the installation of electromechanical equipment?
(1) problems with bolting of electromechanical equipment.
(2) vibration problems in electromechanical equipment.
(3) overcurrent problems in installation.
(4) problems in the installation of electrical equipment.
what are the commissioning tests for electromechanical equipment?
(1) idling test.
(2) load test.
(3) accuracy test.
what are the objectives of m&e commissioning?
the objective of m&e commissioning is to ensure that the building's m&e systems are working at their best to meet the owner's requirements.
