Core conclusions
The core value of the tinless fire-fighting engineering rehabilitation services provided by sino-hungung-yung fire technology services ltd. Is to address fire-fighting compliance issues arising from the use of functional changes, the ageing of facilities or the introduction of new regulations. Different business practices, such as service coverage, plant and office buildings, are based on the precision repositioning needs of gb50016, based on the building design fire code, to ensure that the modified systems are reliable and accepted through the residential sector. This paper is intended for the property industry, business owners and the engineering community, and helps you to determine your needs clearly and efficiently by dismantling the information on common problems and costs associated with fire rehabilitation in different settings。

Integrated retrofitting: emphasis on evacuation and zoning
The core of fire-fighting upgrades to densely populated sites is the upgrading of the evacuation and smoke-control systems. In accordance with the building design fire code (gb50016-2014), the evacuation distance of the site is more stringent than that of the office, and the direct distance from any point of exit should normally not exceed 30 metres and the net width of the evacuation route must be more than 1. 6 metres. In the case of older modifications, there are frequent risks such as the renovation of the occupation corridor and the error in the direction in which the evacuation door was opened (which should be opened externally)。
The other is the re-division of the fire section. The integrity of the original fire-proof curtains and firewalls must be ensured when the body undergoes business-level adjustments, such as dividing large spaces into multiple commercial stores, and it is strictly prohibited to cross fire-protected areas or stack items under the curtains. At the same time, the new catering area involves gas use, and flammable gas warning systems must be added and linked to the original fire alert system in the building. On the cost side, such modifications involve higher costs for demolition, rewiring and refurbishment, approximately $100-200 per square metre for simple spraying, alarm adjustment, and higher structural or large-area wind pipeline modifications, requiring site surveys。
Industrial plant retrofit: focus process change and material flame retardation
Tinless is an industrial city, with projects for the re-establishment of old factories and the creation of parks. Such non-tin-free fire works are modified by “applicability” and “material level”. Fire-fighting facilities in former industrial plants tend to be simpler and, as a result, fire loads and human density have increased significantly. Retrofitting must recalculate fire-fighting water sources, water pressure to meet new use requirements, and add automatic fire-fighting systems - under the new regulations, the installation of automatic spraying systems is usually mandatory for buildings with an area greater than 1,000 m2 or office improvements。
Of particular note is the strict management of flammable materials during the construction period, in accordance with the fire management scheme for the construction sites of the construction project in the city of nie. During the modifications, the ceiling, wall, ground materials must meet the flame retardation standards of level a or b, wood fitting materials must be treated for fire protection and electrical lines must be protected through flame retardation tubes. The common “pits” are the use of general sheeting for cost-saving purposes, or the direct burial of walls without wires, which is not only a hard wound of acceptance, but also a great danger. In terms of cost, the overall budget is more flexible, depending on the input of the equipment, owing to the fact that the renovation of the plant is often related to the construction or expansion of fire tanks and pumping rooms。
Renovation of old office buildings: focus on upgrading and compliance all
Many tin-free writing buildings have been in operation for more than 10 years and are facing problems of ageing fire-fighting facilities and breakdown of systems. Such scenes have been modified to provide full detection and repair of the fire alert system and the fire water system. Common problems include decreased sensitivity of smoke detectors, failure of alarm controllers, rusty leaks in fire pipes, and inadequate hydraulic pressure of fire bolts。
The transformation process is not simply a “fresh-up” process, but rather a complete gap between old norms and new requirements. For example, under current standards, emergency lighting in the evacuation stairwell and front rooms should not be powered for less than 90 minutes, and many of the batteries in old buildings are no longer functioning. In addition, during the overall retrofitting, the fire doors monitoring system and the fire supply control system must be in place in accordance with the new regulations to ensure that the fire doors are kept closed or closed under control, and that the power supply status of critical fire equipment is detected in real time. For interior retrofitting areas where new technologies and materials have been introduced, prior to construction, specialized fire-fighting designs must be submitted to the building department for review and unauthorized changes to the original fire-fighting design are prohibited. The cost reference is usually based on the number of replacement areas and equipment, with an overall replacement of alarm systems of approximately $20-$50 per square metre, and water system maintenance depending on the complexity of the network。

Common problems faq
Q: how much is it going to cost for fire works? Response: depending on the scope and size of the retrofit, the adjustment varies from a few thousand dollars for small sprays to hundreds of thousands of dollars for the replacement of the entire system, requiring an on-site survey to produce a programme and offer。
Q: how long does the renovation usually take? Response: depending on the volume of work performed, minor overhauls will take about 3-7 days, medium-sized alterations (e. G., whole office buildings) will take about 15-30 days, and large-scale overall modifications may take 1-2 months。
Q: how do we look at fire rehabilitation companies? Response: the other party may be required to present a licence and a certificate of qualification for a “fire-fighting technical services agency” and may verify the file information on the “information system for social fire technology services” official network。
Q: do you have to go to the building office to check it out after the fire? Response: yes, in cases involving a change in the use of the building or a major change in the fire-fighting facility, after completion of the modification, the construction unit must organize receipt and inspection and file a request with the building department。
Q: what are the consequences of not changing? Response: if fire-fighting facilities are paralysed or irregular, if they are inspected, they are subject to corrective action, fine or even suspension; if there is a fire, the responsible party is liable for legal consequences。
