mep- building services
TRANSCRIPT
Imagine yourself in the most fabulous building in the
world. Now take away the lighting, heating and
ventilation, the lifts and escalators, acoustics,
plumbing, power supply and energy management
systems, the security and safety systems.
You are left with a cold, dark, uninhabitable shell !!!
BUILDING SERVICES
Everything inside a building which makes it safe and comfortable to be in comes under the title of 'Building services'.
A building must do what it was designed to do - not just provide shelter but also be an environment where people can live, work and achieve.
Building services are what makes a building come to life.

FIRE PROTECTION SYSTEM
WHAT IS FIRE ?
• An exothermic reaction resulting from combination of heat fuel
and oxygen.
• Fire involves rapid oxidation at high temperatures
accompanied by the evolution of highly heated gaseous
products of combustion and emission of visible and invisible
radiation.
• Initiation of fire requires combustible materials, oxygen and an
energy source (heat) to provide ignition. Three components -
fuel , oxygen & heat are referred as the fire triangle
CLASSIFICATION OF FIRE
• Class-A - Fires involving ordinary combustible materials like wood, paper, textiles, rubber
etc.
• Class-B -Fires involving flammable liquids or liquefiable solids, such as oils, solvents,
petroleum products, paints, varnishes etc.
• Class-C - Fire involving gases or liquefied gases under pressure for eg. LPG, Hydrogen
etc.
• Class-D Fire involving combustible metal such as Magnesium, sodium Zinc, Titanium etc.
PRINCIPLE OF FIRE EXTINCTION
• Starvation - Removing or blanketing the fuel
• Smothering - Cutting off the oxygen supply
• Cooling - Removing heat from the fire.

What is a plumbing system
THE PLUMBING SYSTEM IS REALLY MADE UP OF TWO SYSTEMS:
• The supply system that brings in fresh water
• The drain-waste-vent system that takes out used water and sewage
• THE DRAIN-WASTE-VENT SYSTEM ALSO LETS AIR IN AND WASTE GASES OUT.
• BETWEEN THESE TWO SYSTEMS ARE THE FIXTURES (SINKS, TUBS, TOILETS, AND SO ON).

Chilled Water Pipes
• Typically a MEP Contractor each install their own supports from the soffit.
• Followed by water mains, drainage and fire protection pipe work. Generally MEP services that would not require any further access once they had been installed, tested and insulated.
• Followed by the ductwork and its branches to adjacent rooms, which would require testing and insulation.
• Then the chilled water pipework, which also branches off to adjacent rooms and needs to be accessible.
• Electrical containment is always the lowest and final service to be installed. Its completion and subsequent cable installation will be dependent on the mechanical services completion.
• The coordinated installation sequence needs to prioritize the earliest release for HV & LV cable installations.

MEP INTERFACING – PROBLEMS ASSOCIATED
According to the characteristics of the problem, integration requirements,
and construction necessities, the Interface Problems is divided in following eight classifications.
• Coordination with civil structure
• Safety aspects
• Functionality
• Constructability
• Economy
• Efficiency
• Expandability
• Maintainability
• This refers to the process of installing Services, which must be well coordinated to embed the horizontal pipes and vertical sleeves in advance.
• Electrical pipes, monitor control pipes, and vertical sleeves of sewage pipes from the floor slab must be installed prior to slab grouting.
• The work involving the first completed concrete mat for moisture protection and vibration isolators must be executed in conjunction with the embedded sleeves and architectural construction works
COORDINATION WITH CIVIL STRUCTURE
• Safety refers to safety considerations during installation.
• For example, safety is required to prevent hazards such as a water pipe leakage if a water pipe lies above an electrical pipe
SAFETY ASPECTS
• Functionality refers to ensuring that the function of pipes is fully exploited while complying with building codes.
• For example, drainage slopes and routes must be taken into consideration for proper drainage of waste water.
• The installation of fire protection equipment and piping must be arranged prior to other systems in order for the entire fire protection system to comply with fire codes and fire protection permit drawings. Consequently, this has an impact on passing the fire protection inspection and obtaining the occupancy permits.
FUNCTIONALITY
Constructability represents the factors influencing the sequence of installation. The conflicts can be categorized as follows:
• Conflict of equipment in a space - Because of the crowded space, the routing and sequence of installation for large equipment must be checked first.
• Conflict of pipeline in a space - Conditions for stacking and interlacing pipelines causes difficulty in installation and maintenance due to over-crowded spaces and lack of advance coordination
• Crowded installation - Conflicts within the installation space, idle laborers, and poor installation quality can result from problems such as crowded spaces or multiple workers operating simultaneously at a single site. Furthermore, the attitude of “first come first win” or “first do first win” causes conflict in the arrangement of pipelines.
• Pipe materials and dimensions - Installation suffers if the diameter of the pipe is oversized or if the material of the pipe is inflexible or too rigid to be easily cut or molded. If these kinds of materials are applied for the works, they should be installed earlier to prevent conflicts
• Installation of pipeline tiers - When the pipeline layout exceeds two layers, pipes
CONSTRUCTABILITY
• Economy refers to the cost estimates associated with
integration, which can increase due to a lack of
coordination.
• For instance, re-routing a pipeline increases the
lengths of the pipeline and associated costs.
ECONOMY
• Efficiency refers to a lack of integration causing descending
pressure and consuming capacity, which influences the basic
function of MEP systems.
• Additionally, venting conditions around equipment influences
equipment functionality, and should be noted during the
integration of the interface.
EFFICIENCY
Expandability refers to the lifecycle of the facility
causing a demand for the expansion of pipelines due to
the changes in usage or upgrades to the facility.
This increasing demand requires consideration prior to
the installation phase to ensure space for future
expansion of the pipeline.
EXPANDABILITY
• Maintainability refers to the convenience of
maintenance during the operation phase when
arranging the pipeline.
• Maintenance space and operation route must be
taken into consideration.
MAINTAINABILITY
• The major MEP installation projects require the identification of separate arrangements for HVAC, power supply, plumbing, fire protection, telecommunications, and other related systems.
• Specialized consultants and contractors design and construct these systems. Currently, according to technical specifications, each specialty or trade subcontractor is assigned the responsibility of integrating MEP systems.
• Coordination of mechanical and electrical systems to detail their configuration provides a major challenge for complex building and industrial projects
• The knowledge required for MEP integration must be integrated to our System because specialty subcontractors of each system perform tasks individually, proposing a layout according to their own needs, leading to the fragmentation of MEP.
MEP INTEGRATION
• Improper integration at the equipment/pipeline interface results in interference and
inappropriate sequence of jobs during installation can negatively influence the entire project.
• Moreover, the complete integration of the interface reduces the numbers of changes in the
design, decreases the work requiring demolition, addresses problems resulting from
installation error, and increases the overall construction quality of projects.
• Hence, the purpose of integrating the interface is to recognize problems, resolve conflicts,
and perfect the layout of the system for these mechanisms to serve their functions fully.
MEP INTEGRATION
The discussed eight criteria are considered as MEP integration items because they are closely related to considerations of installation integration. To facilitate comparison, let us subcategorized these eight criteria according to three levels INTEGRATION SEQUENCING
The three levels are described as follows:
1. Basic Requirements and Coordination with Civil Structure WorksFunctionality of the 8 criteria fall under this first level of the integration sequencing.
2. Construction RequirementsThis is a second level integration task, comprising the evaluation of installation difficulty, problems associated with the installation of circulation interfaces, and the arrangement of sequencing
3. Cost and Operations RequirementsThis refers to the examination of the price of installation, cost-benefit ratio, and factors related to maintenance and expansion during the life circle of the facility.
