CONSTRUCTION SPECIFICATION FOR COMPRESSOR & METER STATIONS Specification Title: Concrete Specification No.: CS-4 I Page 2 of 17 1. SCOPE This Section prescribes the minimum requirements
for the design, transportation, mixing, and placing of all concrete to be used in the Company concrete structures. Unless otherwise indicated herein, all design and other work shall
conform to and comply with the latest revision of ACI Standard 318 Building Code Requirements for Reinforced Concrete and ACI and ASTM specifications and recommendations references.
2. DEFINITIONS 2.1 "Alkali soil" is soil which contains sulfates of magnesium, sodium, or carbonate of sodium; "Alkali salt" is a soluble sulfate in water. 2.2 "Type I: Normal Portland
Cement" is general purpose cement suitable for all uses when the special properties of the other types are not required. It can be used in construction of pavements, sidewalks, reinforced
concrete buildings, bridges, tanks, reservoirs, sewers, culverts, water pipe, masonry units, and soilcement mixtures. It should be used if no alkali soil conditions exist. 2.3 "Type
II: Modified Portland Cement" is cement that has a lower heat of hydration than Type I and generates heat at a slower rate. It also has improved resistance to sulfate attack. It is intended
for use in structures of considerable size where cement of moderate heat of hardening will tend to minimize temperature rise when concrete is placed in warm weather. In cold weather,
when the heat generated is advantageous, Type I is preferable. Type II cement is also intended for places where added precaution against sulfate attack is important, as in drainage structures
where sulfate concentrations are higher than normal, but are not unusually severe. 2.4 ''Type III: High Early Strength Portland Cement" is cement used where high strengths are desired
to remove forms as soon as possible or to put the concrete into service as quickly as possible and in cold weather construction to reduce the period of protection against low temperatures.
2.5 "Type IV: Low-Heat Portland Cement" is a special cement for use where the amount and rate of heat generated must be kept low. It is intended for use only in large masses of concrete
where temperature rise from heat generated is a critical factor. 2.6 "Type V: Sulfate-Resistant Portland Cement" is a special cement intended for use only in structures exposed to severe
sulfate action, such as in soils or waters of high alkali content. 3. MATERIALS 3.1 Cement All cement shall be Portland Cement and shall conform to ASTM C-150 Type I or II. Other types
may be used if approved by Company prior to use. 3.2 Aggregate 3.2.1 Aggregates shall conform to ASTM C-33 and ASTM C-136 for normal

EnCana Oil & Gas (USA) Inc. Prefabricated Piping Engineering Specification EC-301 Date: 01/10105 Rev.: 0 Page No.9 of 24 For pressure containing parts less than NPS 16, the absorbed
energy of weld metal and heat affected zones shall meet or exceed the requirements of the governing industry specification for the pressure containing part. 8.5.5 Required absorbed energy
for sub-size specimens shall be determined by multiplying the required energy for full size specimens by the subsize specimen thickness, and dividing the result by the full-size specimen
thickness (0.394"). 8.6 Hardness Testing 8.6.1 Each Procedure Qualification Record shall include at least one Vickers hardness survey on a cross section of the qualification weld. The
hardness survey shall be conducted in accordance with ASTM E92 or E384, using a load in the range of 2.2 to 22 Ib (1 to 10 kg). 8.6.2 As a minimum, the hardness survey shall consist
of at least two hardness traverses. a) The first traverse shall be located approximately 0.040" (1 mm) from the outside surface. b) The second traverse shall be located approximately
0.040" (1 mm) from the inside surface. 8.6.3 The hardness survey shall include readings from the weld metal, both coarse grained heat affected zones, and the parent metal on each side
of the weld. HAZ indentations shall be placed in the hardest appearing structures, such as those located adjacent to the toe of the cap or root pass, even if these structures do not
coincide precisely with the line of survey. 8.6.4 Maximum hardness shall be 305 HV. 9.0 WELDER QUALIFICA nON 9.1 General 9.1.1 Welders shall be qualified according to this specification
and ASME B31.8, which mandates the use of API 1104 or ASME IX for welding qualifications. Where a welder is a permanent employee of the Fabricator and is currently qualified for welding
with the Fabricator's approved procedures, then this welder shall be recognized as a qualified welder of COMPANY materials provided all other requirements of ASME B31.8 and API 1104
or ASME IX are satisfied. 9.1.2 Where the Fabricator will be welding using COMPANY welding procedures, or procedures qualified specifically for COMPANY materials, the welder must successfully
pass the qualification requirements given in Clauses 9.2 to 9.6. 9.1.3 When the welder is not a permanent employee of the Fabricator, the welder must successfully pass the qualification
requirements given in Clauses 9.2 to 9.6 regardless of the welding procedures being used. 9.2 Welder Qualification Tests 9.2.1. General 9.2.1.1 Before starting qualification tests, welders
shall be allowed reasonable time to adjust the welding equipment used in the tests and to make at least one practice weld for each procedure. 9.2.1.2 Tests shall be performed using segments
of pipe nipples, full size pipe nipples, or full pipe joints at the discretion of the COMPANY. 9.2.1.3 Test welds shall be assessed for acceptability according to Clauses 9.3 and 9.4.
EnCana Oil & Gas (USA) Inc. Prefabricated Piping Engineering Specification EC-301 9.2.2. Welder Qualification Limits Date: 01/10105 Rev.: 0 Page No. 10 of 24 Welders shall be considered
qualified to make any welds covered by welding procedure specifications to which they have successfully completed a test weld, subject to the conditions outlined in Clauses 9.2.3 and
9.2.4. 9.2.3. Essential Variables For Welder Qualification Welders shall only perform work for which they are qualified, in accordance with governing codes and standards. When a welder
is required to weld under conditions outside the qualified range of essential variables defined by governing codes and standards, the welder shall be re-tested under the appropriate
conditions to the same or another welding procedure specification. 9.2.4. Repair Welder Qualification At the option of the COMPANY, the Fabricator may designate welders to carry out
repairs on weldS performed by others. These designated repair welders must be qualified to the appropriate repair procedure. 9.3 Visual Examination 9.3.1 At the discretion of the COMPANY,
preparation of test welds may be witnessed, and any failure to comply with the welding procedure specification shall be cause for rejection. 9.3.2 Completed welds shall be inspected
visually and any defects, as described in Clause 12.0, shall be cause for rejection. 9.3.3 Test welds failing to pass visual inspection shall not be submitted for further nondestructive
examination and the welder shall be deemed to have failed the qualification test. 9.4 Nondestructive Examination Test welds shall be examined and assessed in accordance with the requirements
of ASME 831.8 (which has provisions for the use of API 1104 and ASME IX), and Clause 12 of this specification. This examination shall include 100% radiography of butt welds or other
nondestructive examination as directed by the COMPANY. Welds meeting nondestructive examination requirements may be destructively tested in accordance with the applicable requirements.
9.5 Retests 9.5.1 If, in the opinion of the COMPANY and Fabricator representatives, failure of a welder to pass a test was because of unavoidable conditions or conditions beyond the
welders control, such a welder may be given a second opportunity to qualify. No further retests shall be given until the welder has submitted proof of subsequent welder training acceptable
to the COMPANY. 9.5.2 Welders may be required to re-qualify at any time if there is any reasonable doubt about their ability. 9.6 Records of Qualified Welders Details of the tests given
each welder and of the results of each test shall be provided to the COMPANY Representative and shall be available for review at the Fabrication facility.
EnCana Oil & Gas (USA) Inc. Prefabricated Piping Engineering Specification EC-301 10.0 PRODUCTION WELDING 10.1 General Date: 01/10105 Rev.: 0 Page No. 11 of 24 10.1.1 Production welds
shall be completed by COMPANY approved welders and weld procedures qualified according to this specification and ASME B31.8, which mandates use of API 1104 and ASME IX for welding qualifications.
10.1.2 The COMPANY will monitor welding at a level required to ensure compliance with the requirements of this specification and any failure to comply shall be cause for rejection. Rejection
of welds can be based on deviation from approved procedures and not necessarily nondestructive examination alone. Weld monitoring by the COMPANY does not relieve the Fabricator of responsibility
for weld quality and performing all quality control activities associated therewith. 10.2 Preparation of Pipe and Fittings 10.2.1. Cleaning of Weld Ends All weld ends and faces which
are to form part of the welded joint shall be cleaned to sound metal immediately prior to welding to ensure complete removal of all paint, grease, oxide, rust and any other extraneous
matter. Cleaning shall extend for at least 2" from the pipe bevel edges on both internal and external surfaces. 10.2.2. Cutting of Pipe Ends Bevels shall be cut by machine tool, or automatic
or semi-automatic oxygen means, so that the finished ends are square within 1/16". Manual oxygen cutting is not permitted. Beveled ends shall be smooth and uniform with dimensions and
geometry as detailed in the approved welding procedure specification. Small gouges, grooves, indentations or other small defects within the joint preparation area shall be removed by
blending with a grinder if possible; otherwise the joint shall be prepared again. No welding repair of bevels shall be permitted. 10.2.3. Preparation for Welding Pipe or Components Having
Different Wall Thicknesses Preparation for welding of pipe or components having different wall thicknesses shall conform to the requirements of Figure 2. Criteria and design principles

of lengths of pipe cut from any joint of pipe and recorded on the shop sheets. Original pipe identification shall be maintained on both pipe ends. Identification by die stamping is not
permitted. 10.2.5. Laminations Any lamination or split end discovered on a beveled end before or during welding shall be completely removed by cutting back, followed by re-beveling to
the satisfaction of the COMPANY Representative. 10.2.6. Intersection of Longitudinal and Spiral Seam Welds Longitudinal and spiral seam welds shall be ground to within 1/32" of both
interior and exterior surfaces, for a minimum distance of 3/8" from the bevel edge. The ground area shall merge
EnCana Oil & Gas (USA) Inc. Prefabricated Piping Engineering Specification EC-301 Date: 01/10/05 Rev.: 0 Page No. 12 of 24 smoothly with weld reinforcement at the end of the grinding,
and shall not reduce the wall thickness of the pipe or component below the nominal thickness. 10.3 Fit-up of Pipe Joints and Fittings 10.3.1. Alignment and Fit-up 10.3.1.1 The alignment
of the abutting ends shall be such as to minimize the offset between surfaces. For pipe of the same nominal wall thickness, the maximum allowable offset shall be 1/16", except that any
greater offset, provided it is caused by dimensional variations shall be distributed uniformly around the circumference of the joint. Where offsets are due to wall thickness difference
and greater than 3/32", such alignment shall require ends prepared according to ASME B31.8. 10.3.1.2 Hammering of the pipe or components to obtain proper line-up should be held to a
minimum and there shall be no deformation of pipe and/or component body due to hammering. Materials shall be protected from any damage during fit-up. 10.3.1.3 When using external line-up
clamps, minor out-of-roundness and hi-low shall be corrected using COMPANY approved wedges. 10.3.1.4 Bolt holes in flanges shall straddle established centerlines (horizontal, vertical,
or layout centerlines) and shall match the orientation of flange connections on matching equipment. 10.3.1.5 Final dimensions of completed assemblies sha II match spool drawings. 10.3.2.
Line-up and Location of Longitudinal or Spiral Weld Seams Longitudinal or spiral weld seams intersecting girth welds shall be offset at least 3". 10.3.3. Fittings and Attachments 10.3.3.1
Branches, fittings and attachments shall be located such that toes of welds are at least 2" from circumferential or longitudinal welds, unless otherwise approved by the COMPANY. 10.3.3.2
Where welded outlets are to be fitted on the surface of a header, the area shall be ultrasonically tested for laminations prior to the fitting of the welded outlet. 10.3.4. Line-up Clamps
10.3.4.1 Line-up clamps shall be used when required by Welding Procedure Specification. 10.3.4.2 Joint alignment shall be such that the weld axis makes a right angle with the longitudinal
axis of the parts to be joined. 10.3.5. Pipe Supports Pipe supports shall be used during fabrication to minimize stress and sag in the assemblies. Tack welding pipe or components to
supports, bracing bars, or counter balance weights is not permitted. 10.3.6. Tack Welds When the COMPANY approves use of tack welds, they shall be made in accordance with Clause 5.3.
10.4 Working Conditions Welding, whether conducted indoors or outdoors, shall not be done when the quality would be impaired by adverse weather conditions, such as moisture, blowing
sand, high winds, or low temperature. Metal surfaces in, and adjacent to, the weld joint shall be dry before welding
EnCana Oil & Gas (USA) Inc. Prefabricated Piping Engineering Specification EC-301 Date: 01/10/05 Rev.: 0 Page No. 13 of 24 commences and while welding is in progress. The COMPANY shall
decide whether the weather conditions are suitable for welding. 10.5 Clearance Adequate clearance shall be available in the work areas so that the welder or welders have ready access
to the pipe joint. 10.6 Preheating, Controlled Cooling and Stress Relieving 10.6.1. General The approved welding procedure shall specify the preheating, controlled cooling and stress
relieving practices or combination thereof which are to be followed. 10.6.2. Preheating 10.6.2.1 Minimum preheat and interpass temperatures shall be in accordance with the following

of the component being joined to the pipe, and through the entire thickness of the component to which the attachment is being applied. For all welds requiring preheat, an area of at
least 4" on each side of the joint shall be maintained at the required temperature. 10.6.2.4 Preheat and interpass temperatures shall be checked using temperature indicating crayons,
thermocouple pyrometers, or other suitable methods approved by the COMPANY, to ensure that the required temperatures are obtained immediately prior to welding, and maintained during
the welding operation. 10.6.2.5 Valves with butt welding ends shall be welded to other components according to instructions obtained from the valve manufacturer. When preheat is required,
it shall be applied from the outside only. As a minimum, clean insulation or other non-flammable materials shall be placed in both ends of the valve bore to protect seals and seats from
weld spatter, heat, and debris. 10.6.2.6 During valve preheating and welding operations, the temperature at a distance 4" from the weld end shall not exceed 350'F, or such lower critical
temperature as may be specified by the valve manufacturer. The actual maximum temperature at the location of the seal shall be measured and recorded by the Fabricator for each weld pass,
to ensure that it does not exceed the preceding maximum temperature limits. This documentation shall be provided to the COMPANY Representative. 10.6.2.7 All repair welding shall be carried
out using a minimum preheat temperature of 250'F. 10.6.3. Controlled Cooling Precautions shall be taken through the use of insulating covers or other appropriate means to control the
cooling rate of the weld after any pass in order to avoid the formation of cooling cracks. This shall apply when there is an ambient temperature of less than 32'F. or as otherwise required
by the COMPANY. 10.6.4. Postweld Heat Treatment (PWHT) (Stress Relieving) 10.6.4.1 When PWHT is required, it shall be in accordance with the requirements of ASME B31.8, and Clause 8.4
of this specification. 10.6.4.2 During the PWHT cycle, the rate of heating and cooling shall comply with ASME Section VIII, Division 1, Paragraph UCS-56. 10.6.4.3 PWHT may be carried
out using suitably calibrated and controlled furnaces, electric resistance elements, or induction coils. PWHT shall not be conducted using torches, ring burners, or exothermic packs.
10.6.4.4 No welding or heating above 400'F shall be permitted after completion of PWHT, except in unusual circumstances specifically approved by the COMPANY, which may require further
PWHT. 10.6.4.5 Threaded connections shall be protected from oxidation during PWHT using a suitable commercially available anti-oxidation compound. If threads are damaged during PWHT,
they shall be chased or re-cut as required by applicable specifications, to the satisfaction of the COMPANY Representative.

temperatures indicated on the welding procedure specification shall be maintained before proceeding with subsequent passes. 10.7.4. Filler and Finish Passes 10.7.4.1 Unless the approved
welding procedure specification states otherwise, no pass shall be commenced until the previous pass has been completed. The second pass shall be commenced as soon as possible after
completion of the root pass and in any case before the minimum interpass temperature has been reached. If this cannot occur due to unavoidable conditions the minimum preheat temperature
shall be maintained and at no time shall the weldment be allowed to drop below the minimum temperature until the second pass has been completed. Circumferential start locations, for
consecutive weld passes, shall overlap by at least 2". 10.7.4.2 The number of passes shall be such that the completed weld shall have a substantially uniform cross-section around the
entire circumference of the joint and shall be uniformly convex. At no point shall the cap pass be below the outside surface of the original weld bevel. The completed weld shall be thoroughly
brushed and cleaned and the reinforcement shall blend smoothly with the adjacent surfaces. 10.7.5. Incomplete Welds Whenever practical, welds shall be completed on the day they are started.
