What are the most common obstacles faced during installation of water supply, drainage, chilled water and fire fighting pipes, what are the solutions?

1.Main obstacles are insufficient coordination of other services like electrical cables HVAC ducts lighting plans with these services.2.There are also problems when the proper levels are not mentioned on the drawings specially where vertical and horizontal runs of pipes combine.3.
The design layout of pipes clashes with other services and make problem during installation and shop drawings.
Solutions are to make coordination drawings and always send one copy of each discipline to other trades for coordination.

The most common obstacles for the installation of fire fighting system is levels and coordination with other service and here under some notices you should consider before the installation:
1- The fire fighting network installation is the last service which will be installed and the first which should be completed.2-Double chechking form the ARC Drawings and their changes.
3- The locations for the fire hose cabinets and special at roof because some designer will not consider the exist of ac units .
4- The stander space for FHC IS150CMX75CM and the most of arc designer will give this space with out consider the riser with supports( could be6" or4" riser) so you need more the75cm...
example for6" riser with the fire hose cabinet you will need150cmx110 at least.5-The valves (ARV,NRV.......)6-At basement and ground floor you shouldn,t not start before fanalize the installation of plumbing system because the plumbing system is depending om gravity .7-study the fire fighting pump room dimension
8- the ventialtion for the water tank and water circulation inside it .9-double check for the false ceiling and specilay at living room and corriodrs areas .1
0- The drain for the zone control valves (plumbing designer sometimes will not consider it)1
0- There are more things i can wright but it,s depending on site so you should always check the site and consider the coordination.

no coordination above cieling ,

The common obstacle is the coordination between fire fighting system piping and other systems like chiller pipes, HVAC duct etc...
Leakage is also the common obstacle, it can be over come by using proper tools, experienced workers and supervision.

The common obstacle is the connections and withstand the operating pressure without leaking Overcome it by testing at a pressure higher than the operating pressure during installations, and the use of appropriate connections for each system, welding or glue or grove coupling or flanges coupling.

leakage,and it can be controlled by introducing some of the sealing agents, that may be internal or external according to the type of leakage.

1 - lack of technical manpower for each item2 - Non-availability of equipment crisis3 - Non-availability of materials approvedSolutions1 - Adoption of blueprints and materials before starting the crisis in advance of the business2 - processing each item before it sufficiently in advance3 - work schedule for each of the items according to the sequence of business4 - Preparation of technical labor, materials, equipment and crisis elements that help end the neglect and tested

the main obstacles of thr pipe is the path of the pipe like:
1- air duct
2- drop beam
3- near shafts
4- the location of the unit like pumps;hose reel

Undoubtedly thorough co-ordination that requires a joint effort by all technical expertise. In addition, the building services shall be given priority as per their functions & recommendation as per codes. Good co-ordination of building services reflects in the efficient functioning & immensely proves to be a boon for the contractor during the execution stage. It also ease the maintenance team to identify each services in troubleshooting & regular services.

all obstacles can be summarized in one sentence, poor design, coordination and construction and I would stress design and coordination is the key source

The most common obstacles are the following:

1. Contractor that installs fire protection systems with less or none knowledge of the codes and standards.

2. Contractor that uses not listed components, such fire pumps, deluge valves, and others.

3. Bad procedures of inspection and maintenance, wich is the most common trouble in companies that don't given due importance to such systems.

4. The assignment of budget in the planning of the annual activities of maintenance in the company is bad or en several cases don't exists.

 

Respecting to the installation, I must say that the major trouble or obstacle is related to te contractor that install the system, no other. Problems such inexperience, irresponsibility, not listed parts (pumps, deluge valves, OS&Y valves, pump engine) or not certified, poor quality materials, such piping, fittings, coatings, bolts, nuts... I could stay until tomorrow listing the reasons and I couldn't finish. So, my recomendation is to check the qualifications and experience of the contractor/installer, as well as the satisfaction level of previous customers, and then you could to take a better decision.

Regards...
