Restoring the take-off control service (ATS) is not just construction work, but a complex process that affects flight safety and the functioning of critical airport infrastructure. Procedure for delivery after repair of VDS is strictly regulated by regulatory documents, since any deviations can lead to a shutdown of the airfield. Project initiators must understand that final acceptance is just the tip of the iceberg, preceded by the stage of checking compliance with technical specifications.
Mistakes at the completion stage can cost huge amounts of fines and temporary loss of airport capacity. Therefore, all participants in the process, from the general contractor to representatives of the customer, are required to strictly follow the established algorithm of actions. Below we will break down the key aspects that need to be taken into account to successfully complete the project.
Takeoff dispatch service requires a special approach to the quality of materials and installation of engineering systems. Every detail, be it cable laying or installation of antenna equipment, must comply with strict aviation safety standards.
Regulatory framework and preparation for acceptance
The basis for all acceptance work is Federal Law No. 384-FZ “Technical Regulations on the Safety of Buildings and Structures”, as well as industry orders of the Russian Ministry of Transport. Submission procedure directly depends on the classification of the object and the volume of work performed. Before starting the final procedures, it is necessary to make sure that all as-built documentation has been collected in full and complies with the requirements of SNiP.
⚠️ Attention: The absence of even one signed sheet in the author's supervision log can become a legal basis for refusal to accept the object by the state commission.
Particular attention should be paid to compliance with project documentation. If during repair GVA changes were made to the design or connection diagrams, they must be reflected in the “as-built” drawings. Without this stage, it is impossible to obtain permission to put the facility into operation.
Preparation begins long before the commission arrives. Technical customer must conduct a preliminary inspection and draw up a list of deficiencies. Ignoring this step often results in the process being delayed for weeks.
Formation of as-built documentation
A key element of successful delivery is a well-executed package of documents. As-built documentation must contain not only acts of hidden work, but also passports for all materials used, certificates of conformity and test reports. Each page must be bound and certified with the seal of the executing organization.
The documentation must include:
- 📄 General work log with records of all stages of construction and renovation.
- 📐 Executive schemes with actual deviations from the design.
- 📝 Inspection reports critical structures and hidden work.
- 🔌 Electrical measurement protocols and testing of grounding systems.
The documentation for engineering systems life support. Protocols for testing ventilation, heating and fire extinguishing systems must be signed by representatives of specialized laboratories. Test reports must not expire at the time of submission of documents to the commission.
Use digital archives to store copies of executive documentation - this will speed up the search for the necessary acts during repeated inspections.
Inspection of engineering systems and equipment
VDS engineering systems are the “circulatory system” of the facility, ensuring the operation of dispatchers and navigation equipment. Comprehensive testing carried out after completion of all construction and installation work. During this period, the operation of power supply, water supply, sewerage, ventilation and air conditioning systems is checked.
Particular emphasis is placed on uninterruptible power supply systems (UPS) and diesel generator sets. They should turn on automatically when the main power is turned off for a specified time. Tests are carried out under load simulating real operating conditions.
Communication and alarm systems are also subject to inspection. Dispatcher communication must ensure sound purity and absence of interference, which is critical for flight safety. All results are recorded in comprehensive testing reports.
☑️ Checking engineering systems
Testing of security and communication systems
Safety is the number one priority for any aviation infrastructure facility. Security systems include a security and fire alarm system, an access control system (ACS) and video surveillance. Their verification is carried out by specialized organizations that have the appropriate licenses.
During the tests, the operation of smoke, temperature and flame sensors is checked. The system must not only give a signal, but also launch evacuation algorithms: unlock the turnstiles, turn on the smoke removal and warning systems. Video surveillance checked to ensure coverage of all critical areas and recording quality.
The resistance of communication systems to external electromagnetic influences is tested separately. This is especially important for VDS, where a large amount of radio equipment is concentrated.
⚠️ Attention: A malfunction of the smoke removal system or false alarms of the fire alarm are critical defects that block the delivery of the facility.
Specifics of acceptance in the aviation industry
Acceptance of objects at airports has its own unique features due to high flight safety requirements. Aviation security requires additional inspections that are not typical for ordinary civilian objects. Representatives of the airport’s aviation security services and the Federal Air Transport Agency must participate in the acceptance.
The compliance of materials with fire safety requirements (flammability and toxicity classes) is checked. Finishing materials in VDS premises should not emit harmful substances when heated and should have antistatic properties.
Attention is also paid to the ergonomics of dispatcher workplaces. Lighting, noise and vibration levels must comply with sanitary standards, since people’s lives depend on the concentration of attention of personnel.
Why is screening of VDS premises important?
VDS premises often require shielding to protect sensitive equipment from external electromagnetic interference and prevent information leakage. Upon acceptance, the integrity of the shielding circuit and the effectiveness of grounding are checked.
Drawing up an acceptance certificate and commissioning
The final stage is the signing of the acceptance certificate for the completed construction of the facility. This document is signed by all members of the working commission: customer, contractor, designer and representatives of supervisory authorities. Acceptance certificate is the basis for putting the facility into operation and beginning to use it for its intended purpose.
The act records the absence of deficiencies or sets a deadline for their elimination. If defects are identified, a defective statement is drawn up and acceptance is suspended until they are eliminated.
After signing the act, the object is transferred to the balance of the operating organization. From this moment the warranty period begins, during which the contractor is obliged to eliminate the identified deficiencies at his own expense.
| Acceptance stage | Participants | Resulting document | Date |
|---|---|---|---|
| Pre-check | Customer, Contractor | Defective statement | 1-3 days |
| System testing | Special organizations, customer | Test reports | 3-7 days |
| Working commission | All participants in the process | Act of the working commission | 1 day |
| State acceptance | State authorities, customer | Certificate of acceptance into operation | On schedule |
Successful delivery of the VVA is possible only if the as-built documentation and the actual condition of the facility are in full compliance, as well as the absence of critical comments on the security systems.
Frequently asked questions (FAQ)
What warranty periods are established for VDS repair work?
The warranty period is usually 5 years for building structures and from 2 to 5 years for engineering systems, but specific periods are determined by the contract and may vary depending on the type of work and materials used.
Is it possible to hand over a VVA property in stages?
Yes, the legislation allows for the phased delivery of objects if each stage represents a complete part of the complex, capable of functioning independently or as part of other phases, which is often used in the reconstruction of existing airports.
Who is responsible for safety during acceptance testing?
Responsibility for safety during testing lies with the organization carrying out the work, but the customer is obliged to ensure access and coordination of actions in the conditions of an operating airport, observing aviation safety rules.
What to do if the commission reveals inconsistencies?
If inconsistencies are identified, a defective statement is drawn up with a list of corrective actions. Acceptance is suspended until all comments are eliminated and re-checked; the deadlines are established by the protocol of the commission.
