Q&A'S

QUESTIONS AND ANSWERS

Q1. Reference par. 1.5.8 Special Qualifications: “a) At least four Contractor’s employees shall possess a refrigeration license F-GAS…”. This specific requirement seems to exceed the actual needs for this contract since one (1) single employee with F-GAS refrigeration license allows a firm to perform labor works for an amount up to 200.000,00 € (as per ACCREDIA Technical Regulation RT-29 rev.02). Would the Government consider to revise this specific requirement reducing the number of employees in possess of F-GAS certification directly employed by the main contractor?

R1. The requirement remains unchanged.

Q2. Reference par. 5.5.5 Quality Standards, 5.5.5.1 states that the cleaning activities shall ensure a maximum limit of 0,075 g/mq of deposited particulate after the cleaning, detected with the method of “VACUUM TEST NADCA”. Based on technical reviews COLLOM or similar methods work very well on brand new ductwork where the main issue consists of dust deposited upon the inner surface of the ducts themselves.

COLLOM approach may result by far less effective in guaranteeing the level of results required by this SOW when it comes to thoroughly clean an older ductwork covered with multiple layers of dust, humidity and other foreign matters. A mechanical cleaning type of work is for sure more effective and long lasting than COLLOM and can for sure guarantee the required level of output required by this SOW. Can the Government allow other methodologies rather than just COLLOM?

R2. The requirement remains unchanged. Use of an air blade allows the removal of dirt while at the same time maintaining integrity of the ducts and their internal insulation where present.

5.5.13 Cleaning activities

5.5.13.1 Preliminary actions: Prior the beginning of cleaning activity, the system shall be inspected and checked accurately, in order to identify eventual abnormal conditions that could be an obstacle to the cleaning activity or could void the effectiveness. Eventual anomalies shall be reported to COR in written (email) and cleaning activities shall not begin until approval is received by COR. The beginning of cleaning without following this procedure implies the acceptance of any anomalies and their restoration/repair will be Contractor’s responsibility and at Contractor’s expense. Particular attention shall be used for the Air Handling Unit outside air intake inspection in order to verify that there are no obstructions or any contaminants and verify that the anti-birds net (if present) is in good shape. The cleaning activity shall not be performed in internal insulated ducts that, for particularly degraded conditions (excessive exfoliation, collapse, etc.), could be even more damaged by the cleaning action; in this case, Contractor shall completely remove the degraded insulation and proceed with internal coating with encapsulant product. Any different decision shall be authorized by COR, after visual verification of the conditions of the system.

5.5.13.2 Proceed with removal of all removable material/furniture that could eventually obstruct the access to the work area or that could be damaged during cleaning execution and store them in an appropriate area indicated by maintenance personnel, until the completion of the cleaning.

5.5.13.3 The firefight fixtures (like smoke detectors, fire dampers, etc.) shall be properly protected prior beginning of cleaning and they shall be inspected by Contractor at the end, in order to ensure the proper functioning.

5.5.13.4 Contractor shall coordinate with COR the disable and the following enable of the fire alarm, in order to avoid accidental false alarms during cleaning of ductworks.

5.5.13.5 Contractor shall coordinate with COR the turn off of the ventilation equipment prior beginning of cleaning and diligently follow local safety procedures, in particular to turn off fans automatic switches.

5.5.13.6 Contractor shall take microbiological samples of deposits on the internal ducts sufaces at least in three different locations per each building’s floor, for each system composed by AHU and its ducts, before and after the cleaning/disinfection activities. Sampling shall be performed by using medical gloves, placing the “agar” plates “Petri” type to count the total bacteria load and the fungus load on the internal ducts surface, using the appropriate timed pressure positioner “Rodac-Weight” and placing the samples in appropriate containers provided by Contractor at his expenses; alternatively, the use of sterile sampling swabs is allowed on appropriate supports (for example made by Copan Italia). For the analysis of the bacteria and fungus load of the air supplied by the system Contactor shall use an appropriate “SAS” type analyzer by collecting two air samples (one for total bacteria load and one for fungus load on agar plates “Petri” type) for each floor and each system composed by AHU and its ducts, before and after the cleaning/disinfection activities, and plasing them into appropriate containers. Containers shall be properly identified and have a label with the following info:

A) System identificiation B) Sample location C) Date and time of the sample D) Name of the operator who took the sample E) COR signature (COR shall witness the sampling)

The quantity of bacteria (and/or molds and/or fungus) shall be determined by performing analysis made by independent lab having Accredia Certification, and analysis will be Contractor’s responsibility and expense. The measure of the dust residual contaminant present in the ducts after the cleaning shall be performed using the “Vacuum Test” NADCA system and analyzed by Accredia Certified lab. COR and Contractor shall make sure that sampling locations respond to general conditions representation of the duct. Sampling locations have to be foreseen for each system composed by AHU and ducts, before and after cleaning:

Monitoring on surfaces: total bacteria load; fungus load.

AHU’s fan section AHU’s coil Supply air ducts (3 samples per floor) Return air ducts (3 samples per floor)

Monitoring of supply air using SAS analysis Measure of residual contaminant after cleaning 2 measures of residual dust by using the “Vacuum test” NADCA system in the supply air duct at each floor 2 measures of residual dust by using the “Vacuum test” NADCA system in the return air duct at each floor Measurment of Legionella presence (only for AHUs having adiabatic humidification): 1 sample of water used for humidification collected from the drip pan of each AHU

5.5.15 Cleaning activity and removal of deposits

The execution of the cleaning shall be done considering that Contractor, with the approval of COR, has the responsibility to determine the best way to perform the cleaning on each system and, if requested, Contractor has to give a detailed description of the procedures that he wants to follow. Any deviation from the techniques or from the methods of cleaning shall be approved by COR.

Cleaning and disinfection of the system shall be done starting from the AHU and proceeding downstream the ductworks.

5.5.15.1 Methodology:

Reclaim, cleaning and disinfection of Air Handling Units (AHUs):

AHUs shall be manually vacuum cleaned using equipment in compliance with actual norms, degreased, cleaned and washed with pressure jet water or by using steam for the coils showing hard dirt attached on the fins, then AHUs have to be disinfected by high pressure spraying products approved by Ministero della Salute.

Once the residual water has been dried, visual inspection of the AHU shall be performed in order to highlight any mechanical issue (such as belt low tension, water leaks). In particular, the following activities shall be done taking care of protecting the equipment or the electrical system inside the AHU:

Removal of exterior case panels Filters removal Vacuum cleaning of the dirt Descaling cleaning with appropriate product Removal of limestone with proper product Emptying of water from condensate drip pans Usage of anti-bacteria and detergents Washing of all surfaces by using water jet Disinfection by using disinfectants registered by Ministero della Sanità of the drip pans Air blowing cleaning of filters (if in good conditions) and reinstallation Cleaning of coils by using water jet or steam Disinfection of coils by sprayingdisinfectant product Final wash with water Eventual parts showing rust signs shall be covered by using atoxic epossidic resin Riassemble of the AHU parts Restart of the unit

5.5.15.2 Cleaning and disinfection of ductworks:

A. Ductworks without internal insulation

1. Cleaning of internal surface of ductworks shall be performed by using the compressed air system COLOM type or similar, to be introduced into ductworks through adequate access points. Access points shall be prepared following the procedure described at par.5.5.7.1. Contractor shall remove any deposit on the square ductworks internal surfaces along their entire length and sides (top, bottom and sides), especially taking care of the corners where dirt accumulates easier, and along the whole circumference on the round ductworks. Also, particulare care has to be taken while cleaning branches from main duct to the single rooms where diffusers/grills are installed. Spiral flexible ducts shall be replaced with new ones or cleaned one by one with appropriate nozzle.

2. The selection of the equipment shall be done considering the following prescriptions: a) the only usage of the exhaust fan, even if having high flow rate and power, is not considered sufficient by itself;

b) The equipment prescribed is the compressed air type that uses the COLLOM technology or similar;

c) Similar equipment are considered acceptable only if:

c.1) the compressed air equipment can be used also to wash the ducts by controlled spraying of disinfectant solutions or encapsulants or paints, sprayed inside the ducts, only after the compressed dry air cleaning, in order to ensure that the disinfectant solution gets attached completely and uniformly on all internal surface, avoiding any liquid leak on the outside of the ducts and avoiding the creation of other openings on the ducts. The distribution of the sprayed solutions shall occur on the internal surfaces of the ducts and along their entire extension in order to perform a real wash and complete sanification of the whole ductwork.

c.2) the compressed air equipment has to perform the same efficiency along main ducts, ascendant/descendant curves, vertical ducts, avoiding the creation of additional openings and ensuring to maintain the integrity of the system.

c.3) where the dimentions of the ducts are so big that don’t allow the usage of the described technology…
