Punch Control Procedure
1.
Objective
To establish procedure in verifying a system, test section, subdivision of a plant or equipment in accordance with the
approved design and other technical requirements of the project.
To define methods of preparation, issuance, clearing and control of punch.
2.
Scope of Work
This shall apply to all Solar Philippines projects, new and existing.
3.
Responsibility and Authority
a.
Site Manager:
Execution and control of this procedure during construction prior to provisional acceptance period and assign to
whom will undertake the work for punch clearing.
b.
Quality Assurance and Control Engineer:
Review and update of all punch list items. Collect all punch list records and submit to all members of the punch
listing team to assure that the punch should be cleared/verified.
c.
Operations and Maintenance Team:
Conduct inspection activity of plant components or systems that is within the scope of punch listing activity. Verify
that items are cleared and certify that the system is acceptable and operations ready.
d.
Construction Team:
Conduct initial inspection of plant components or systems prior to and at the punch listing activity. They are
responsible for punch clearing or resolving deficiencies under punch category A, ensuring that the system and its
components are ready for Testing and Commissioning activities.
e.
Testing and Commissioning Team:
Responsible for punch clearing or resolving deficiencies under punch category B, ensuring that the system is
ready to be energized or subject to operating conditions.
4.

a.
Punch
Defect, deficiency, modification, and outstanding work
b.
Punch List
List of defects, deficiencies, modification, and outstanding work prepared by authorized engineers, quality control
personnel, operation and maintenance teams, field supervisors, licensors, and subcontractors.
c.
Test Package
Identified and agreed upon sections of the project/plant to be inspected for punch listing.
d.
Punch Category
Table 1 shows every discipline’s punch category. Punch shall be cleared before execution of the indicated project
stage/milestones.

Project Stages/Milestones
i. Testing and Commissioning:
A unit/system is essentially complete and ready to be tested to verify that they will show no faults if
subjected to operating conditions. All major works are completed, and minor faults shall not interfere
with this stage.
ii. Energization
All unit/system test requirements are done and ensured they are operational as per design.
iii. Provisional Acceptance:
System can be turned over to Operation and Maintenance and all requirements for completion have
already been met. Systems shall be continuously observed by both construction and O&M team for
defects.
f.
Test Package
Compiled complete set of documents describing details of a system subjected to test. Test packages may include
Approved for Construction Drawings, Field Change Notices, Design Change Notices, As Built Drawings, QAQC
Documents, Test results done to components of the systems and others.

Notes:
1.
In order not to exhaust the capacity of the punch listing members, punch listing activities shall be done in sections.
Test Package limit shall be agreed upon by Construction Team and QAQC, where a Single Line Diagram shall be
marked up to determine the limits of test package. The QAQC Engineer based on the limits shall collect related
quality documents of the equipment and activities, Field Change Requests, Change Orders, and other supporting
quality documents, while the Field Engineer shall collate all latest revision and as built drawings.
Related quality documents of the test package shall be the following but not limited to:
a. Factory Acceptance Testing Results
b. Material Certificates
c. QAQC Inspection and Test results as per Inspection and Test Plan
d. Field Change Request
e. Site Instructions
f.
Change Orders
All Shall be compiled into a file with the identified system limitations as identified limits of the test package.
2.
The punch listing team shall compose of the following:
a.
Field Engineer(s)
b.
QAQC Engineer(s)
c.
Operation and Maintenance Representative
A meeting shall be called upon by the Site Manager at the start of the Punch Listing activities so that all members
shall have a common knowledge of the process and limits. The attendees of the meeting shall be recognized as
authorized signatories of the Punch List form. Other signatories of the punch list shall be authorized first by the
original member through proper channels prior to signing any documents.
3.
By physically walking through the system, members shall identify deficiencies and list them down in the punch list
form with complete details, including the name of the member who identified the punch and his/her signature. In this
stage, members shall agree upon the categories of the punch.
Punch identified by the members of the punch listing team in a particular system after the date of system
walkthrough shall not be recognized as official punch item. Punch items shall be identified or raised by a member
with the other members present and once a system punch list has been finalized, alteration, addition or reduction
will not be allowed.
4.
Final punch items shall be cleared by Construction Team/Field Engineer with prioritization based on categories and
project schedule. Every item cleared shall be verified by members to be closed out on the punch list with names
and signatures affixed. The responsible person for the next stage (Testing and Commissioning Teams or
Operations) shall determine if a punch item, if not cleared at the required time, can be carried over to the next
project stage.
6.
Upon confirming that all specific category closed punch items are closed, the system shall be ready for the next
stage where responsible person of that stage shall be notified.
7.
Upon completion of all testing and commissioning and all systems are in operational condition, Engineering,
Procurement, and Construction (EPC) Group shall issue a provisional acceptance certificate to Operation and
Maintenance Group, signifying that the responsibility of taking care of the plant is handed over to them. Including in
this certificate are all the test package of the project both in hard and soft copies.
