The Contractor Shall Provide Sufficient Competent Personnel Including A Qualified Fitter And Electrician, As May Be Necessary To Install And Operate The Pumping Unit. D. Control Of Discharge Rate The Contractor Shall, During The Pumping Tests, Provide A Suitable Gate Valve On The Discharge Pipeline, To Facilitate Easy Control Of The Discharge Rate. Discharge Shall Be Controlled With A Valve Fitted Behind The Elbow And Measured With A Water Meter, Fitted At A Distance Of Not Less Than 1 M Behind The Valve. An Additional Measuring Device (e.g. Oil Drum And Stopwatch) Shall Be Provided For Back Up And Checking. Drawdown And Recovery Of The Water Level Is To Be Monitored With A Water Level Indicator Through The Piezometer Pipe At Intervals As Specified By The Engineer On The Site. The Engineer May Demand Water Quality Measurements. He Will Provide The Monitoring Forms. E. Water Level Sounding Pipe 1. The Contractor Shall, If Instructed By The Engineer, Provide And Install A Temporary Tube Of At Least 1 Inch Diameter From The Top Of The Well To 2 Meters Above The Pump Bowl Assembly To Facilitate Easy Measurements Of Water Level. The Tube Shall Be Open Only At The Bottom And Top. 2. Payment For Providing, Installing And Removing The Tube Shall Be Deemed To Be Included In The Rates Given For Pumping Tests. F. Discharge Rate Monitoring Discharge Rates Up To 10 L/s (36 Cum/hr) May Be Measured By Drum Filling. Discharge Rates In Excess Of 10 1ps Shall Be Recorded With A Water Meter Or By A V-notch Weir Or With Orifice Discharge Pipe. All Items Are Subject To The Engineer's Approval Before Start Of Drilling. G. Definition Of "pumping Unit" The Equipment Specified In Section H.b – H.f Is Referred To As The Pumping Unit. H. Pumping Procedure The Engineer Will Determine The Pumping Procedure Necessary To Obtain The Objectives Of This Contract. I. Suspension Of Pumping If The Engineer Finds The Condition Of Any Equipment, Personnel, Fuel, Lubricants Or Accessories Will Prejudice The Quality Of Data Obtained From Any Pumping Test, He May Suspend The Work In Accordance With The Provisions Of The Conditions Of The Contract. J. Equipment Breakdown During Pumping 1. The Pumping Must Be Continuous And At A Constant Rate During The Pumping Tests. The Engineer Will Instruct The Contractor As To The Expected Maximum Duration Of Each Pumping Test Before Start Of Each Test. 2. If Pumping Is Interrupted Or The Discharge Rate Fluctuates By More Than 5% Of The Designated Discharge Rate, The Test May Be Repeated After A Period Of Recovery Determined By The Engineer. 3. If Any Pumping Test Is Interrupted Because Of Equipment Breakdown Or Inadequate Supervision Or Discharge Control, No Payment Will Be Made For Any Pumping Period Before Commencing The Test. K. Duration Of Tests 1. The Step-drawdown Pumping Tests Shall Be Performed On 5 Steps With A Duration Of 1 Hour Each. 2. The Continuous Constant Discharge Pumping Tests Shall Be Performed For A Period Of 3-5 Days, Unless Otherwise Specified In The Special Conditions Of The Contract Or Unless Otherwise Instructed By The Engineer. L. Temporary Pipeline 1. The Contractor Shall Provide A Temporary Pipeline As Directed By The Engineer For The Discharge From Pumping Tests And For Clearance To A Suitable Watercourse Or Drain. 2. Under Certain Circumstances When Re-infiltration Cannot Be Avoided Or It Is Costly To Provide For This Condition, The Engineer Shall Decide To What Distance From The Well, Water May Be Discharged On The Ground. I. Cement Grouting A. Scope The Contractor Shall, Unless Otherwise Specified In The Special Conditions Of The Contract, Provide The Cement And Mixing Equipment Required For The Mixing Of The Grouting Indicated In The Tentative Well Design And Shall Place The Cement Grout As Specified. B. Grouting Material 1. Cement Grout Shall Consist Of A Mixture Of 95% Portland Cement, 5% Bentonite And Clean Water, Mixed In The Proportion Of 52.5 Kg Of Portland Cement/bentonite To Max. 30 Liters Of Water. 2. All Cement Shall, Unless Otherwise Specified In The Contract Documents, Conform To The "specifications For Portland Cement" (astm C150-latest Revision). C. Method Of Placing Grout Material 1. The Method And Equipment For Placing The Grout Shall Be To The Approval Of The Engineer. No Method Will Be Approved That Does Not Provide For The Forcing Of Grout From The Bottom Of The Casing/hole/annulus To Be Grouted, To The Surface. Flushing Of The Annular Space With Fluid To Assure The Space Is Open And To Remove Loose Material Will Be Required To The Contractor Before Grouting Is Commenced. 2. Any Grouting Operation Shall Be Continuous And Before Starting, Sufficient Grout Shall Be Mixed To Complete The Whole Operation. During The Grouting Operation, The Mixed Grout Shall Be Continuously Stirred. The Contractor Shall Provide Such Tanks, Hoppers And Other Equipment As May Be Necessary To Meet These Requirements. D. Setting Time No Work Will Be Allowed On The Well Within A Period Of 72 Hours After Completion Of Grouting Unless Quick Setting Cement Is Used. In Such Case, The Idle Period May Be Reduced To 24 Hours Subject To The Engineer's Prior Approval. J. Well Completion A. Scope The Contractor Shall Provide And Operate All Equipment Necessary To Restore The Site As Near As Possible To Its Condition Before Commencement Of Drilling And Shall Furnish And Install A Well Head Cap As Specified In The Contract Drawings. B. Site Restoration The Site Shall Be Restored To A Condition As Nearly Possible To That Which Existed Before The Well Drilling And Testing Activities Commenced. This Work Shall Include, But Not Be Limited To, Restoration Of Fences And Structures, Removal Of Drill Cuttings, Leveling Of The Disturbed Ground Surfaces And Replacement Or Compensation For The Destroyed Plants And Landscaping. C. Well Head Capping The Well Head Shall Be Completed With A Well Head Assembly Fully Welded To The Upper Casing As Well As A Water Level Sounding Tube With Screw Cap In Order To Prevent Any Unauthorized Tampering Of The Well.
