VALENZUELA MEDICAL CENTER Tender

Description Item No. Unit Item Description Qty. Unit Cost Total Cost 1 Lot Complete Supply Of Labor, Tools And Equipment For The Pneumatic Testing Of Fire Sprinkler System Of Valenzuela Medical Center - Ids Building Scope Of Works: A.) Precautions: - Pneumatic Testing Involves The Hazard Of Released Energy Stored In Compressed Gas In The Event Of A Breach Of Containment. - Care Must Be Taken To Minimize The Chance Of Brittle Fracture During The Pneumatic Leak Test. Test Temperature Is Important In This Regard, As Low Temperatures Can Increase The Chance Brittle Fracture, And Must Be Considered When The Designer Chooses The Material For Construction. - Parts Of Mechanically Assembled Systems Must Not Be Adjusted While The System If Under Pressure. - Adequate Anchoring Shall Be Provided For Equipment To Be Tested. - Calibrated Pressure Gauges Shall Be Used During The Test. - Valves Shall Be Used To Isolate The System Equipment From The Pressure Source. B.) Testing Manifold And Pressure Relief Device (prd): - Any Supplementary Valves, Piping, Hoses, Etc. Required For The Test Shall Be Inspected And Accepted By The Valenzuela Medical Center Personnel. - A Prd Shall Be Provided. - The Set Point Of The Prd Shall Not Be Greater Than The Test Pressure, Plus The Lesser Of 345 Kpa (50psi) Or 10% Of The Test Pressure. C.) Test Fluid: - If Not Air, The Gas Shall Be Nonflammable And Nontoxic. D.) Test Pressure: - The Test Pressure Shall Be In Accordance With The Code Of Construction (usually 110% Of The Design Pressure) E.) Preparation: - The Safe Distance, As Identified In The Test Procedure, Shall Be Identified By Placing Appropriate Barriers. - All Staff Associated With Or Conducting A Pneumatic Pressure Test Shall Be Deemed Competent By The Organization Conducting The Test. - Removal Of Existing Fire Sprinkler Heads - A Pre-test Safety Meeting Should Be Conducted To Ensure All Personnel Present On The Site That May Be Exposed Are Aware Of The Hazards, Mitigations, And Emergency Response Plan. - All Visual Inspections And Non-destructive Examinations Required By The Code Of Construction Shall Be Completed And Evaluated As Acceptable. - A Pre-test Inspection Shall Be Made To All Connections To Verify Proper Assembly And Tightness, Positioning Of Valves, Overpressure Protection, And Control Of Test Medium. F.) Pressurization Procedure: - The Test Pressure Shall Be Gradually Increased Until The Pressure Reaches The Lesser Of 170kpa (25psi), Or 1/2 Of The Test Pressure. At This Time A Preliminary Check Shall Be Made. If Leaks Are Identified, Then The System Shall Be De-pressured And Repairs Made To Correct The Deficiency Prior To Proceeding. - Thereafter, The Pressure Shall Be Gradually Increased In Steps Until The Test Pressure Is Reached (i.e 25% 50%, 75% Of Mawp, Followed By Test Pressure). The Pressure Shall Be Held At Each Step Long Enough To Equalize The Piping Strains. The Safe Distance Identified In The Procedure Must Be Observed During This 'portion Of The Test. If Leaks Are Identified, The System Shall Be De-pressured And Repairs Made Prior To Proceeding Re-pressurization Must Follow All Of The Above Steps. - The Test Pressure Shall Then Be Reduced To The Design Pressure Before Examining For Leakage. G.) Installation Of Existing Fire Sprinkler Heads - After The Pneumatic Testing Conducted And Verify That The System Has No Leak, The Existing Fire Sprinkler Head Should Be Installed. H.) Testing And Commissioning - Conduct Testing And Commissioning I.) Removal Of Testing Manifold: - Any Supplementary Valves, Piping, Hoses, Etc. Required For The Test Shall Be Removed After Testing Is Complete. J.) Duration Of Work: 7 Days K.) Warranty: Three (3) Months On Supplies And Labor 1 177,883.33 177,883.33 Grand Total 177,883.33
