ANNOTATION: This article describes in detail the processes of assembling
constructions of engineering communications in modern buildings and structures. The
stages of assembly - preparation, marking, installation of equipment, reinforcement,
testing and commissioning - are consistently described. Recommendations are given
on the integral connection of systems with building structures, materials, equipment
used, and safety standards. The article is intended for technical specialists, civil
engineers, and students of the field, and is prepared based on a practical approach .
Key words: Engineering communications, building structures, installation
techniques, construction supports, pipeline mounting, utility installation, structural
integration, fastening systems, cable trays and ducts, mounting brackets, seismic
protection, load-bearing elements, fireproofing of utilities.
INTRODUCTION
Engineering communications constitute the main vital systems of modern
buildings, structures and industrial facilities. Proper installation of these
communications is a prerequisite for the safety, convenience and long-term operation
of the device. Installation work is one of the important stages of the construction
process, during which work is carried out in close connection with building structures.
Classification of engineering communications
Engineering communications are divided into the following main groups:
Water supply systems
– cold and hot water for
Heat supply systems
– heating and hot water for
Water water ( sewerage ) systems
– internal and external
Electricity supply and lighting systems

Ventilation and air conditioner systems
To the fire against protection systems
Information and communication systems (COMMUNICATIONS,
internet, signaling )
Every one of the system assembly process technician documents and
construction construction with coordinated without done is increased .
Construction constructions with integration
Engineering systems often of the building main passes through structures (
walls , floors , ceilings ) or they with closely connected will be . Therefore :
Construction in the project in advance
canal
,
mine
,
passage places
,
brackets
( kreplenia ) in the eye is being held .
Systems
hide
( e.g. ventilation ) between the pipes and the ceiling )
aesthetic and technician to the reasons according to done is increased .
Temperature expansion , tremor and sinkholes into account received
compensatory devices
is installed .
Montage technology and methodological stages
4.1. Preparation stage
Project estimate documents study
Materials and equipment placement
Workers and of experts qualification check
Construction the area preparation ( construction) supply , security
measures )
4.2. Marking and measurement
Laser target signs using pipes , cables directions is marked
Montage brackets place is marked
Measurement accuracy high in accuracy to be ( ± 3 mm) from not to
exceed necessary )
4.3. Pipe and cable lines installation
Pipes cutting , bending , preparation ( welding , plastic) connection , press-
fitting )

Cable and cable trays installation
Insulation to make ( heat , acoustic) or to the fire resistant )
4.4. Equipment assembly
Pumps , filters , meters , valves , automatic management equipment
Every one equipment technician passport and project according to is
installed
4.5. Reinforcement and additional constructions
On the wall , on the ceiling or independent to the support fastening
If necessary assembly platforms , iron carcasses will be built
4.6. Testing and check
Hydraulic test ( pressure with )
Electricity insulation test ( megometer) via )
Gas in the pipes density and leak control
Acting and to exploitation submission
In the montage applicable equipment
Tools and equipment
Purpose
Electricity welding apparatus Pipes connect
Plastic pipe welder
Polypropylene pipes for
Laser target marker
Correct direction designation
Press-crimp device
Fittings connect for
Pipe bend lathe
External pipes for
Pumped test apparatus
Pressure under test
Construction-normative documents
Montage works following normative to documents appropriate is done :
Uzbekistan construction standards ( UzKMQ )
SNiP
,
GOST
,
ISO
standards
Technical regulations
and
exploitation passports
Construction control documents ( act , deed , test) protocol )

Security and quality control
Every one assembly process technician control under to be condition
At altitude in the works height equipment ( rope , belt , cable ) is used
Electricity and gas in the assembly certified experts participation will
Every one test result writing in the act reflection delivered
Conclusion
Engineering communications assembly is construction technological and
engineering in the basics thorough planned , to standards suitable accordingly
execution need was responsible is the stage . Every one system separately to the
complexities has and they constructions with appropriate in a way integration to do
necessary . Qualified assembly works of the building service the deadline extends ,
safety provides and exploitation expenses reduces .
