2. EXISTING SITUATION

The Chief of Mission’s Residence, CMR, was constructed in 1950’s. Since its first residence, the plumbing and heating lines of the building was renovated in time due to the needs of the CMR by diverting the lines with some new plumbing additions. Moreover, some of the rusty and corroded pipes were replaced in time. However, it has been observed that whole plumbing and heating lines and some of the equipment have completed their economic life span, which results in all piping and some of the equipment to be renewed. This report explains what needs to be done in order to modernize the plumbing and heating lines with addition of new equipment and new pipe lines.

The hydronic heating lines and plumbing lines have been located with thermal camera system and review of existing design drawings with the help of technıcal staff of the client. A survey of CMR was completed to create the demolition works and new pipe line design. The room dimensions are noted in the drawings as length and width and celling height so that calculations can be made for the work to be done. The ceiling height is shown as well. The contractor has to take measurement from bottom of the beams ‘n some rooms as the piping will not be allowed thru beams.

There existing facility is being heated from the system in the boiler room. The hydronic piping is diverted to all rooms and some of the rooms are heated with panel type and cast iron type radiators, while some rooms our heated with floor heating systems. The domestic water system of the faculty starts at the Water Tank & Piping room and diverted to shafts. The cold water is circulated thru the roof attic and reaches the point of use. There is an old style water treatment unit connected to the ice machine in the piping room as well. The sewer system is collected thru shafts and exists the facility at dıfferent locations to end at the manholes.

3. DESIGN CALCULATION

The heat loss calculation or domestic water calculation is not necessary for the facılıty as the existing system is adequate enough to supply the requirements of the CMR.

4. THE DEMOLITION WORKS

Demolition works can be divided into minor and major works. In minor works, access openings will need to be created to remove the vertical pipes in the shafts. There are approximately 15 shafts in the Ambassador Area (master bedroom and its footprint below levels) and 20 shafts in the rest of the building. Major demolition work is at the boiler room and plumbing room, which includes removal of some old equipment such as heat exchanger and 2 accumulation tanks in the boiler room and demolition of concrete water tank ın the plumbing room. Furthermore, at locations such as Recreation room and Theatre room, there will be demolition of radiator panel gypsum board covers and existing suspended ceiling respectively. Please note that it is Client’s aim that Demolition works should be carried out with at most attention to the existing facility and The contractor should “Restore any damaged area to the previous condition. Submit a design and get approval from FAC for the major restoration prior to start”. Minimum major architectural touch of work should be the aim of the contractor. Please note that the Client has mentioned that there is no asbestos material in the building.

Plumbing, sanitary-waste water and hydronic piping removal includes all pipes in in shafts, risers, and horizontal pipes in basement. Some pipes are buried in floor or wall. Some pipes run in partial suspended ceilings and false beams. During removal these architectural bodies will be damaged. All these damaged parts will be repaired same as existing condition. In basement floor some trench digging and new piping is required. Some additional pipes will be burried in basement floor. The floor will be repaired to the existing conditions.


Water tank and piping in attic will be removed. Any existing damaged existing glass wool insulation and the glass wool insulation that may be damaged during the removal of water tank and piping will be repaired and / or renewed.

During pipe demolition, all riser shafts maybe cut to free pipes for removal. Because in past years some parts of shafts are filled by concrete debris. Shafts are covered by gypsum boards reinforced with wire mesh. Some shafts passing throug bathrooms are covered ceramic tiles. Some pipes buried in floor or wall will be left as they are, and replaced new piping will run in new false ceiling, false beams or false columns. The panel radiators will remain and cast iron radiators are to be replaced. The floor heating system in the rooms will remain in place in order not to increase the architectural works but they will be sealed and left outside of the new heating system. Panel radiators will be installed instead. The pipe lines in the second floor bathrooms will not be changed as they are lately renewed.

Existing concrete water tank will be demolished to be replaced with same capacity new stainless modular water storage tank will be installed.

Please see some pictures form the facility showing the existing situation as below: (will be include by the Clinet)

5. THE PIPING WORKS

The work includes all domestic water, sanitary sewer and hydronic heating pipes removal and laying of new piping lines with some additional equipment installation

Existing boilers will remain at their same place, they shall not be removed or replaced. All piping in existing boiler room will be removed. A new piping system will be installed. New system will be ready for future condensing boilers. 4 existing `Grounfdoss Magna` pumps and 2 `Siemens` 3-way valves will be stored safely for reuse. All other existing piping and equipment etc. will be removed and renewed in boiler room. A new waste water trench will be created in floor.

Existing hot water heat exchanger and storage tanks will be replaced by new hot water generators having their own internal hot water coils. New hot water generators will be made of stainless steel. See the required Sepc Section for Details.

Due to long operating life expectations PPRC pipe reinforced by glass fiber will be used. All piping in basement will be insulated. All insulation will be covered with fabricated PVC jackets. Pipes in riser shafts may not be insulated, since paths are very short, reinforced PPR pipes has low conductivity. On the other hand, insulated pipe installations will be difficult in the vertical shafts. Any future pipe replacement will also be difficult in the shafts if the pipes are insulated vertically. (The client requests pies in riser shafts shall be insulated as much as possible depending on the shaft and application void available in the shaft. The contractor should be in full coordination with the Client for each application location in the riser shafts) Please note that the quantity of insulation in riser shafts has not been included in the BOQ).

All bathrooms in second floor are renewed recently. So piping in these bathrooms will remain untouched and only the old pipes will be replaced up to new piping in first floors suspended ceilings.

Existing panel radiators will remain, except the ones shown on demolition plan, which are cast iron radiators that will be replaced with panel radiators. The size of the radiators is to be chosen according to the existing one. The panel radiators that will replace the floor heating system is chosen according to the volume of the room. All existing and new panel radiators will be equipped with thermostatic control valves, except the ones in bathrooms. New radiators are “compact type”. Pipe connection will be made with “H” valves and straight or bend type radiator valves. Existing radiators’ pipes will be connected with compact radiator valves and chromium coated pipes. As the heating capacities are same, contractor maybe requested to change dimensions of the radiators shown on drawings. Final panel radiator dimensions will be decided together with the client and contractor on site taking into consideration of ‘interior architectural matters.


The normal size radiators are chosen in order to keep the esthetics of the rooms. However, if the client wishes larger size can be chosen so that lower hot water flow, longer economical life of pipes, less electricity thru pump and ability to change the boilers to new theology condensing boiler if the esthetics of the room is not major criteria.

New stainless modular water storage tank will be installed. The capacity will be 6 m3. A water filter and softener system will be installed.

6. THE ELECTRICAL WORKS

Minor electrical works, MCC and DDC panels, for new equipment such as new pumps, new water softener and new hot water generator sensors, outdoor air temp sensors, 3-way valves with electrical actuator etc. will be required. Cabling for this new equipment, cable trays or conduits according to the client’s choice will need to be supplied and installed.

7. THE ARCHITECTURAL WORKS

It is important for the contractor to survey the facility, verify the dimensions and see minor and major Architectural works that are required to renew the plumbing and hydronic heating system lines. (Pictures from the rooms will be added in at next design stage)

8. IMPORTANT NOTE

Please note that Rain Water Collection Downspouts will remain in place.

9. OPERATION SEQUENCE

Boiler pumps provide water flow through the boiler at constant flow rate. They are primary circuit pumps. As boiler # 1 primarily feeds the hot water generator, the temperature setting of this boiler will be higher than the boiler #2 in most of the year. Therefore, its collector groups were formed between boiler 1 and hot water generators, and the hot water flow was provided primarily between the boiler and the hot water generators. In order to transfer excessive water from hot water generator these collectors are connected to the building heating system collector.

East and west zone pumps are secondary circuit pumps supplying water to radiators. The secondary circuit is variable water flow, due to the thermostatic valves on the radiators.

When the radiator thermostatic valves are closed water flow on boilers will drop, so a boiler return bypass line is formed between the return and supply collectors to pass water from the boiler at constant flow rate.

The existing 3-way valves are used to prevent cold water to enter the boiler. When the boiler return temperature drops below 60C, the 3-way valve will close the turn off the building return and open the by-pass from collectors. This automation will be provided by the contractor.

The by-pass line between the B and AB outputs of the 3-way valve is provided to operate the 3-way valve as a 2-way valve. If the return water temperature from radiators exceeds 60C, and the thermostatic valves are closed flow through boilers will drop. Bypass between the B and AB outputs guaranties constant flow on boilers.


The return line from radiators is also connected to the supply collector. When 3-way valves are closed to prevent the cold water to enter the boiler, there will not be water flow on secondary circuit supply pumps. To guarantee the passage of water through the secondary circuit pumps as this line is necessary.

The boiler heating circulating pumps will be controlled by the boiler thermostat.

The primary circulation pumps of the working boiler must always be switched on.

The MCC panel and wiring of the pumps and the boiler will be provided by the contractor.
