QUALITY CONTROL METHOD I Introduction Binh Duong Solid Waste Treatment Plant Page of 89 II Bases for quality control of the project III Detailed quality control measures Chapter 11 - CONCLUSION Chapter - PREAMBLE I – Scope of the Project The scope of work to be undertaken by the contractor consists of the construction, manufacture, delivery, installation, testing and commissioning of a sewerage collection system and sewage treatment plant and the technical training for the operation and maintenance of the constructed Works The sewerage collection system consists of main trunk sewer pipelines having nominal diameters or indentified inside diameters of 400mm-1200mm, branch sewer pipelines having diameters of 200mm-315mm and tertiary (collection) sewer pipelines having diameters of 110mm-160mm, along with requisite manholes, inspection chambers, diversion chambers, junction boxes and cleanout appurtenances Ten (10) pumping stations will be required for lifting to the level of sewerage gravity pipelines or pumping to the sewerage pumping mains The sewage treatment plant shall have capacity of 17,650 cubic metres per day (ADWF) for this Phase works, expandable in the future to the ultimate Phase capacity of 70,600 cubic metres per day (ADWF) The contractor will be required to provide plant in accordance with the drawings and specifications, meeting design and performance criteria as specified in the bidding documents The Contract Scope of Works includes the following: a) Sewerage Collection System Construction Works, which include: Main trunk sewer pipelines (DN400-DN1200) procurement and installation Branch sewer pipelines (DN200-DN315) procurement and installation Tertiary sewer pipelines (DN110-DN160) procurement and installation Pre-cast reinforced concrete sewer manholes/ Inspection chambers (DN1000-DN1800) procurement and installation Pre-cast reinforced concrete sewer junction boxes (DN300) / Diversion chamber (DN600) / Cleanouts (DN350) procurement and installation Sewerage pumping stations installed in pre-cast manholes (DN1800-DN2000), incl power supply and control system Sewerage pumping stations installed in cast-in-situ concrete structures, incl power supply and control system Sewerage pumping mains (DN250-DN500) Misc sewerage structures b) Sewage Treatment Plant Construction Works, which include: Site preparation works including piling for structures; Structural works for the sewage treatment plant; Roads, drainage, final site leveling and landscaping; Yard piping including main trunk inlet sewer, interprocess piping and final effluent piping; STP site buildings and structures including, administration/laboratory building, service vehicle garage, workshop building, influent pumping station, inlet works, advanced sequencing batch reactor tanks (4), gravity thickener tanks (2) and thickened sludge pumping station, sludge dewatering building, UV disinfection building, blower building, power generation building, odor control system building, guardhouses and small miscellaneous structures c) Sewage Treatment Plant M&E (Plant) Installation Works which include: Influent Pumping Station, including four (4) dry pit pumps and associated equipment; Inlet Works, including fine screens, grit and grease removal, flow measurement and flow splitting equipment; Advanced Sequencing Batch Reactor (ASBR) equipment; Gravity thickeners and thickened sludge pumping equipment; Centrifuge sludge dewatering, sludge pumping and chemical feed equipment; UV disinfection equipment; Aeration blower equipment; Emergency power generation equipment; Odor control system equipment; Power supply and distribution; SCADA control system II - Advantages and Disadvantages of the project Advantages - Working area has many small paths, therefore, the Contractor can arrange the construction of many sections at the same time So the Contractor can control the construction progress - Working in the nighttime, the Contractor can use the public lighting system Disadvantages - The execution of the project is carried out in the urban, so it is affected by the traffic Traffic safety is paid attention to during the construction - Working such as pipeline, pipelines area passes through many existing public utilities cabling, telephone cable, existing water supply drainage, and local residents’ domestic water along the route - Working site is spacious, therefore it is difficult to make arrangement and protect the yard, the workshop and properties on site - The execution of the project will influence the lives of the local residents and environmental hygiene during the project Chapter - GENERAL REQUIREMENTS I – Standards and codes applicable during the construction AISC S326 ANSI A14.3 ASTM A36 ASTM A48 ASTM A53 ASTM A108 ASTM A123 ASTM A496 ASTM A500 10 11 12 13 14 15 16 ] Specifications for the Design, Fabrication and Erection of Structural Steel for Buildings (referred to herein as AISC specification) Ladders-Fixed-Safety Requirements Standard Specification for Structural Steel Standard Specification for Gray Iron Castings Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated Welded and Seamless Standard Specification for Steel Bars, Carbon, Cold-Finished, Standard Quality Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products Standard Specification for Steel Wire, Deformed, for Concrete Reinforcement Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes ASTM A525 Standard Specification for General Requirements for Steel Sheet, ZincCoated (Galvanized) by the Hot-Dip Process ASTM A536 Standard Specification for Ductile Iron Castings ASTM A563 Standard Specification for Carbon and Alloy Steel Nuts ASTM A582 Standard Specification for Free-Machining Stainless and HeatResisting Steel Bars, Hot-Rolled or ColdFinished ASTM A666 Standard Specification for Austenitic Stainless Steel, Sheet, Strip, Plate, and Flat Bar ASTM A668 Standard Specification for Steel Forgings, Carbon and Alloy, for General Industrial use ASTM A780 Standard Practice for Repair of Damaged Hot-Dipped Galvanized Coatings 17 18 19 20 21 22 23 24 25 ASTM A786 Standard Specification for Rolled Steel Floor Plate ASTM B26 Standard Specification for Aluminium-Alloy Sand Castings ASTM B36 Standard Specification for Brass Plate, Sheet, Strip, and Rolled Bar ASTM B221 Standard Specification for Aluminium and Aluminium-Alloy Extruded Bars, Rods, Wire, Shapes, and Tubes ASTM B308 Standard Specification for Aluminium-Alloy 6061-T6 Standard Structural Shapes ASTM B632 Standard Specification for Aluminium-Alloy Rolled Tread Plate ASTM F467 Standard Specification for Non-Ferrous Nuts for General use ASTM F468 Standard Specification for Non-Ferrous Bolts, Hex Cap Screws, and Studs for General Use ASTM F593 Standard Specification for Stainless Steel Bolts, Hex Cap Screws, and Studs Aluminium Association (AA): 30-86, Specifications for Aluminium Structures Standard Specifications for Highway Bridges Standards on Wires and Cables 26 BS 6004 IEC 227 PVC insulated cables (non-armoured) for Electrical Power ] 27 BS 6346 PVC Electrical Supply insulated cables for 28 BS 6749 29 BS 5467 IEC 502 Armoured Cables with XLPE and HEPR thermosetting Insulation, 600/1000V and 1900/3000V 30 BS 6622 IEC 502 Extruded cross-linked polyethylene Insulation, 3800/6000V up to 19000/30000V 31 BS 6500 IEC 227 Insulated Flexible Cords 32 BS 6207 IEC 245 Insulated Cables Part 33 BS 6360 Copper Conductors for Cables 34 BS 6234 Polythene PVC Insulation and Sheaths -
