Foreword
 Clients look for and pretend that
 Plants are as cheap as possibile
 And realization time (for E+P+C phases) the most
reduced ones
 Subcontractors want to appear the most
competent and cheap during the tendering phase,
sometime they simply quote “to survive” only.
 It’s general opinion (and we agree 100% on this
idea) that it’s only with the contract management
and above all from the claim management that a
Subcontractor can gain and not merely executing
what contract stipulate for him

Method Description
“As planned” vs “As
built”
It’s a retrospective method which
involves comparing the baseline (“as
planned”) against the “as built”
construction schedules
“impacted as
planned”
Tecnique that forecasts or predicts a
delay’s effect on project’s completion
date. It involves the insertion or addition
of activities representing delays or
changes into the baseline schedule to
determine the impact
“Collapsed as built” Retrospective tecnique that begins with
the as-built and then subtracts activities
representing delays or changes
Window analysys ->a)
Time Impact and b)
“snapshot analysis”
Tecniques that generally utilize
contemporaneous schedule updates in
conjunction with the as built facts related
to a delay or a change

1. INTRODUCTION
1.1. PURPOSE
The purpose of this document is to provide general guidelines for the administration of
construction subcontracts at site on projects managed directly by ABB PA.
It addresses the duties and responsibilities of the Subcontracts Administrator(s) on the
construction site. It specifies the flow of information between ABB PA Site and Home Office
operating centres as well as with the subcontractors and other agencies, approval levels,
communication/archiving procedures and interfaces for construction subcontracts administration.
1.2. SCOPE
Generally speaking, subcontracts administration is the process of ensuring that the technical,
commercial and legal provisions of a subcontract are complied with by all parties. This process
begins after the signature of the subcontract between ABB PA and the subcontractor. It starts at
the Kick Off Meeting (KOM) with pre-construction activities, continues on a daily basis during
the performance of the work including in particular, monthly invoice verification and approval
and ends with the final acceptance and the associated activities such as the final payment, close-
out and activation of specific warranty provisions.
1.3. HIGHLIGHTS
The keys to successful Subcontracts Administration are highlighted below:
• Maintain good documentation,
• Index documentation according to the claim index,
• Answer all Subcontractor correspondence,
• Know the Subcontract to avoid undue Variations,
• Ensure that contractual notice has been given wherever required,
• Prepare the monthly progress charts for each Subcontract,
• Prepare the subcontracts close out back up documentation for the Head office,
• Send, on a monthly basis, to the Head Office Subcontracts Department Manager the
Subcontract Site Monthly Report extracted from the Subcontracts computerised administration
system.
1.4. DEFINITION
1.4.1. Main Contract
It is the contract between ABB PA and the Client that fixes ABB PA's technical and legal
responsibilities and obligations towards the Client for the Project. (The administration of the
Main Contract is the responsibility of the Project Manager).
The Main Contract generally falls into 2 main categories:

31. ABB
Page
4/34
GE3
• Lump Sum Turn Key contracts where construction subcontracts are awarded by
ABB PA under its full responsibility.
• Services contracts where construction subcontracts are awarded by the Client or by
ABB PA for and on behalf of the Client and where ABB PA is responsible for
construction management. Services contracts can be of various type: lump sum for
services (including or not supervision) and material, reimbursable of supervision
and construction, etc..
1.4.2. Construction Subcontract
Usually, the Construction work is divided into several subcontracts depending on the total
size of the job, either per trade and/or per geographical area or per multi-discipline
packages.
The award of construction subcontracts is managed from Head Office under the
responsibility of the Procurement Department Manager (Refer to Subcontracting
Procedures).
Under the Main Contract with the Client, a SUBCONTRACT is an agreement between
ABB PA (CONTRACTOR) or the Client and a construction company
(SUBCONTRACTOR) which undertakes a single or a group of construction activities
including supply of labour and materials, construction equipment and may include some
engineering.
1.4.2.1.Lump Sum Turnkey Contract
In this case, SUBCONTRACTOR has no contractual relationship with the Client. ABB
PA is totally responsible to the Client for the proper performance of the Work including
the subcontracted work
1.4.2.2.Service Contract
In this case, SUBCONTRACTOR has a contractual relationship with the Client. ABB
PA is totally responsible for and on behalf of the Client for the management of
SUBCONTRACTOR.
1.4.3. Local Subcontract
This is a short-term subcontract under any of subcontract categories listed above, awarded
to local subcontractors at site for performing additional or ad-hoc works.
The award of such subcontracts is managed by the Subcontracts Administrator at site under
the responsibility of the Construction Manager.
1.4.4. Work Order
This is a written order given to the SUBCONTRACTOR for performing Variations, i.e.
Work not included in the original scope of work of the subcontract. It thus becomes a
contractual commitment.
The issue of Work Order(s) is managed by the Subcontracts Administrator with proper
internal approvals and in accordance with the General Terms and Conditions of the
SUBCONTRACT.

1.4.5. Approval/Signing Authority
Approval as used herein denotes ABB PA management approval for the expenditure of
Project funds prior to the execution of the Commitment. The approval may be delegated in
accordance with the provisions of management directives.

2. ADMINISTRATION [TOP]
2.1. GENERAL
This chapter describes the recommended organisation of the subcontracting group at the
construction site in order to strictly follow the Subcontract administration procedure. After a brief
description of the subcontracting group, the role and specific responsibilities of the Subcontracts
Administrator is described in detail. Communication and archival procedures are also outlined.
2.2. SUBCONTRACTING GROUP
Typically, the subcontracting group on a construction site should consist of one or more
Subcontracts Administrators reporting to the (site) Subcontracts Administration Manager and a
dedicated secretary, depending on the size of the project.
On a small or medium size project, the Subcontracts Administration duties as described herein
may be entrusted to the site Manager or the Cost Controller.
2.2.1. Subcontracts Administration Manager
He is nominated by the Head Office Subcontracting Department Manager. He reports to the
Construction Manager on Site. His job description is given in Construction Guide Document
book 4. He will ensure compliance by himself and his team of the provisions of the present
document. He will also ensure that ABB PA team on site and the Subcontractors are made
aware of and follow the said provisions. He supervises the Subcontracts Administrators and
the Quantity Surveyors.

2.3. FILING SYSTEM REQUIREMENT
2.3.1. General
The Subcontracts filing is made by the Subcontracts Administrator.
The purpose of a good filing system is to store the information / data in a structured and
systematic manner so that it can be retrieved and referred to quickly by anyone. The accurate
filing of all the Subcontract documents, correspondences and minutes of meetings cannot be
overemphasised considering the large sums of money involved in construction jobs and the
potential claims from the Subcontractors for certain inherent additional works deemed to be
in the scope of work, loss of time not attributable to ABB PA or the Subcontractor and the
non fulfilment of contractual obligations by ABB PA.
Each Subcontract administration filing system must have the following features:
• A system integrated with the site project filing system.
• An index showing each subject in the system.
• Security especially after office hours and on holidays.
• Filing cabinets should be fire proof (if practical) and should be locked while not in use.
2.3.2. Electronic Filing
In addition to the paper filing, a centralised electronic documentation base will be established
on site, except for small projects. This base will contain all the Subcontracts document filing
as defined hereafter, either in electronic format or for incoming documentation in scanned
format. The Subcontracts Administrator shall ensure that all documents in the base are fully
and properly indexed.
In particular:

37. ABB
Page
10/34
GE3
• Each document shall be indexed according to the claim index (as per § 5.4.2 ).
• Each Subcontractor correspondence shall be linked to each ABB PA correspondence
(uplink and downlink)
• Each ABB PA correspondence shall be linked to each Subcontractor correspondence
(uplink and downlink)
2.3.3. Paper Filing Requirement
2.3.3.1.Filing Instruction
• Each file folder must be cross-referenced to the Index file.
• Each folder should contain one subject only.
• Each Subcontract file should be maintained separately and headed by a tab, indicating
the Subcontract name, number and the subject of the file.
• Logs for all Subcontract files within each particular Subcontract should be maintained
in either a separate file or in a binder divided by Subcontract number containing the
logs for all Subcontracts.
2.3.3.2.Recommended Filing System
The following list of files is recommended within each Subcontract administration filing
system:
2.3.3.2.1. Pre-contract award files
a) Copy of the Main contract with the Client / Owner
b) Final bid tabulation, successful bidder's proposal, all correspondences between ABB
PA and the bidder during the bidding stage and ABB PA's in-house estimate
c) The letter of intent, signed Subcontract with authorised Subcontractor personnel list
and Client / Owner's confirmation of ABB PA's authority for Subcontract
administration matters.
2.3.3.2.2. During the execution of the subcontract

2.5. MEETINGS
The purpose of this section is to provide guidelines to maintain records of all meetings and important
telephone conversations related to a Subcontract - listing date, participants and synopsis of
discussions.
The following types of meetings can be held related to each awarded Subcontract:
• Kick-off / Pre-construction Meeting
• Progress Review Meetings
• Coordination Meeting with Subcontractors
• Internal Review and Trends Analysis
2.5.1. Kick-off/pre-construction meeting
After the award of Subcontract and prior to mobilisation of Subcontractor personnel to the site, the
Head Office Subcontracts Manager shall call for a Kick-Off Meeting in order to set up the ground
rules between the Subcontractor and ABB PA for working at the particular construction site and to
highlight the main aspects and particularities of the Subcontract. These rules will form the basis of
the understanding between the parties of each other's responsibilities and obligations.
This meeting shall be chaired by the Construction Manager assisted by the Home Office
Subcontract engineer (if required), the subcontract administrator, the safety manager, the Field
Engineer, the schedule Engineer, the area supervisor(s) or their delegates.
During this meeting all facets of the work shall be addressed: Introduction of key personnel from
both sides, brief presentation of Subcontract to all attendees, standard procedures and forms,
reports, planning, drawing and contractual documents distribution, labour relations,
communication procedures, invoicing methods etc.
Also, it is practical that the Planning engineers from both sides set up a separate meeting soon
after the Kick-Off Meeting in order to prepare the Subcontract schedule and progress curves
(contractual): this progress curves will bind the Parties (refer to the General Terms and Conditions
of the Subcontract) and be the basis of further discussion related to time extension / accelerations
Variations due to late delivery of CONTRACTOR's deliverables (access, drawings, material,...).
See attachment FORM_.2A3 KOM agenda.pdf for the usual agenda for the meeting.
Early Action Items Letter:
Either before or immediately after the kick-off meeting, an early action letter should be sent to the
Subcontractor. This letter will specify the procedures and the contractual requirements that require
immediate action by the Subcontractor.

2.6. REPORTS
2.6.1. Site Subcontracts Monthly Report
The Site Subcontracts Monthly Report is a monthly financial report issued by the Subcontracts
Administrator for all Subcontracts in force including local Subcontracts. It consolidates all the
relevant information regarding all Subcontracts giving an estimate of identified exposure to date.
From this document the Cost Control Manager can build his cost forecast by adding the required
provisions for the financial consequences of future growth or other events.
The report is issued after the approval of the Monthly Financial Status Report, but not later than
the 15th of each month.
The above report is highly confidential in nature. One copy will go to the Cost Control Manager.
The report shall also be dispatched to the Subcontracting Department Manager who will take care
of the internal distribution at the Head Office.

Superintendent. Since this report is a significant record in the evaluation and settlement of
claims, care should be taken to ensure the accuracy and completeness of the report.
The supervisors in charge will ensure that the Subcontractor issues the reports promptly during
the life of the Subcontract.
The original, after despatch to the Scheduling group for productivity measurement purpose,
shall be retained by the Subcontracts Administrator.
The Subcontracts Administrator shall review all reports for items that have potential cost
impact on Subcontracts, for problems to be discussed with the Subcontractor or brought to the
attention of the Construction Manager.
The report is prepared and numbered sequentially for every working day, including Saturdays,
Sundays and holidays, if applicable.
2.6.4. Weekly construction equipment report
2.6.4.1.Purpose
The purpose of weekly construction equipment reports from Subcontracts administration point
of view is essentially to maintain a record of duration of assignment of construction equipment
on site in case of future claims.
2.6.4.2.Reporting Procedure
All Subcontractors involved in the jobsite shall prepare a weekly construction equipment
report (mandatory).
It is reviewed by the ABB PA supervisor in charge and approved by the Construction
Superintendent. Since this report is a significant record in the evaluation and settlement of
claims, care should be taken to ensure the accuracy and completeness of the report.
The supervisors will ensure that the reports are issued promptly by the Subcontractor during
the life of the Subcontract.
The original shall be retained by the Subcontracts Administrator.
2.7. CHECKLIST FOR SUBCONTRACT ADMINISTRATION
2.7.1. Purpose
The scope of Subcontract Administration is to ensure that the technical, commercial and legal
provisions of all the Construction Subcontracts are complied with by all the concerned parties.
This process begins as soon as a Subcontract is signed between the parties and continues on a
daily basis during all the pre-construction activities and construction until work completion,
provisional / final acceptance, Subcontract closeout / final payment and activation of specific
warranty provisions. It is, therefore, very important that all the records related to every
Subcontract are kept meticulously and it is ensured that the work is completed in total compliance
with the scope and specifications. Further, any potential claim from a Subcontractor should be
recognised and resolved promptly, all changes to scope processed in time. ABB PA Head Office
should be informed of the Subcontracts status regularly on a monthly basis.
In order to help the Subcontracts Administrator on site in effectively meeting the above
requirements, a checklist has been developed on all aspects of Subcontract administration (see
attachment - FORM_.241 SC admin checklist.pdf). It is a tool to be used at the start of each
Subcontract to ensure that all required administration items are in place and continue to be used
till the end to assure quality of services.

• The contractual drawings and documents listed in the Subcontract, with mandatory
indication of the revision index of each of these drawings and documents.
• The estimated quantities given as indicative.
• The main work Price Schedule.
A Price Schedule for additional works (per operation, controlled expenses) is used for
compensation of works for which the main work price schedule is not applicable.
3.3.1.2.Material Takeoff
The material take off is the document allowing the final calculation of quantities and price of
the main work. An intermediate reassessment of the quantities and price of the main work
should be made at the Head Office in case of a significant change in the volume of work under
the Subcontract. This take off is based on the main work Price Schedule items. It generally
reflects the quantities and values per:
• Type of work
• Work item
• Price schedule item
3.3.1.3.Quantity Calculations
The quantities are calculated from the last issue of "Issued For Construction" drawings:ies are calculated from the last issue of "Issued For Construction" drawings:

The Material Take Off shall be used as basis for calculation, in case of significant
modifications, of the Subcontract Price adjustment amendment.
The calculation will be done with:
• The initial lump sum,
• The known or expected take offs of modifications that will be established from the
revised drawings and contractual documents,
• The committed extra Work Orders,
• A provisional sum for extra Work Orders to be issued.
The addition of the above amounts leads to a provisional account that allows the preparation
by the Subcontracts Administrator of a SUBCONTRACT Price adjustment amendment that
will be issued by ABB PA Head Office.
3.4. PROGRESS OF WORK

GE3
The follow up and the calculation of the physical progress shall be performed by means of
CPMS ("Construction progress Measurement System") software.
3.4.1.2.Work progress sheets
(see attachment - FORM_.3A1 work progress.pdf) The "Work Progress" is the detailed
document that allows the recording and the follow up of the different work phases of one work
item and/or type of work items.
The build-up of such "work progress" sheet depends upon both:
• The schedule follow up split (geographical)
• The Subcontract follow up split (per type of work item)
The document is a computer print out issued by the Scheduling group to the Supervisor, filled
by the Supervisor or by the Subcontractor and checked by the supervisor and entered into the
CPMS system.
The filled document is distributed to the supervisor and filed by the Scheduling group.
3.4.1.3.Physical progress calculation – for subcontract administration
(see attachment - FORM_.3A2 physical prog. - productivity.pdf)
Two steps have to be considered for progress follow up:
• Data input:
The data input is calculated from the information given by the Supervisors and the
"work progress" sheets
• Progress calculation:
The overall physical progress is calculated by the Scheduling group using CPMS
software (refer to Construction Book 4 – Chapter 2).
The Monthly Progress report is generated by CPMS and distributed by the Scheduling
group to the Subcontracts Administrator, the Supervisor and filed by the Scheduling group.
3.4.1.4.Monthly financial status report
(see attachment - FORM_.3A3 monthly financial status.tachment - FORM_.3A3 monthly financial status.pdf)
This document shows the value of works performed during the month, including Variations,
the calculation of the invoiceable amount of the works performed during a month including
escalation if applicable. It is established from the "Monthly Progress Report, Progress of
Works (Subcontract)" sheet.
The "Monthly Financial Status Report" is approved and signed as follows:
• The issuer
• The Subcontractor
• The Cost Controller
• The Site Manager
• The Client (if required by the main contract)
The document is hand filled on a paper wad and distributed after approval to:
• The Subcontractor

up by ABB PA head office accounting department who shall check conformity with the Monthly
Financial Status Report.
3.4.3. Subcontracting close-out
The close-out of the Subcontract is prepared upon completion of the works by way of amendment
by the Head Office Subcontracts manager. The Subcontracts Administrator will request
Subcontractor to submit its Project of Final Financial Statement (see attachment - FORM_.3A4
final financial statement.pdf) and will prepare all back-up documentation allowing the Head
Office Subcontracts manager to negotiate the closeout.
The closeout amendment is drafted by the Site Subcontracts Administrator and negotiated and
issued by the Head Office Subcontracts manager.
4. SUBCONTRACTS VARIATIONS [TOP]
4.1. PURPOSE
This procedure covers the basic requirements for handling Variations in the Work that occur during
the execution of a Subcontractor's Work as per the Article "Variations" of the General Conditions of
Subcontract and as may be amended in the Special Conditions of Subcontract and subsequently the
Variation Procedure which is to be distributed to each Subcontractor and to be strictly adhered to.
A Variation to a Subcontract is a change in the form, quality or quantity of the Work or any part
thereof as defined in the Subcontract. In principle the work should be of the same nature as that of the
Main Work or fall within the area of expertise of the Subcontractor, failing which the work should be
directed to another Subcontractor. A Variation request may be initiated by ABB PA (or the Client in
the case where ABB PA acts for and on behalf of the Client) or by a Subcontractor.
Implementation of a Variation requires the issue of a Variation request, followed by the issue of a
Work Order prior to execution of the related works. The Variation will be subsequently incorporated
into a Subcontract amendment. Each of these stages shall be subject to the relevant approvals as
described hereafter.
4.2. INITIATION OF A VARIATION REQUEST
4.2.1. By ABB PA (or Client)
All requests for Variations to the scope of Work of the Subcontract by ABB PA (or the Client)
will be prepared by the ABB PA Supervisor on a Variation Request form as per attachment -
FORM_.4A1 Variation request by ABB.pdf).
The Variation Request will be handed over to the Subcontracts Administrator who shall check the
Subcontractor's contractual entitlement to a Variation.
If the contractual entitlement to a Variation is established, the Subcontracts Administrator shall
log the Variation request in a sequential log for ABB PA initiated Variations commencing with

51. ABB
Page
24/34
GE3
1001 onwards. This sequential log is incorporated into the Computerised Subcontracts
Administration system described in Chapter 7.
The Variation Request shall be signed by the Supervisor, the Subcontracts Administrator, the Cost
Control Manager, the Site Manager and the Client (in the case where ABB PA acts for and on
behalf of the Client) prior to issue to the Subcontractor.
The Subcontractor shall be required to submit a cost and schedule proposal for the said works by
the stipulated date (normally within 8 days) on a unit rates, a lump sum or a reimbursable basis as
directed by ABB PA.
After discussion and agreement on the Subcontractor's proposal, a Work Order will be prepared as
per attachment - FORM_.4A3 work order.pdf by the Subcontracts Administrator, stating the
charge code as per table 1 and a clear description of the works.
The Work Order shall be signed by the Supervisor, the Subcontracts Administrator, the Cost
Control Manager, the Site Manager and the Client (in the case where ABB PA acts for and on
behalf of the Client) prior to issue to the Subcontractor for signature and implementation of the
works.
No Variations shall be started before having been approved by the Site Manager (and the Client in
the case where ABB PA acts for and on behalf of the Client).
If the Work Order amount exceeds the Site Manager delegation, authorisation will also be
requested from the Project Director.
4.2.2. By the Subcontractor
All requests for Variations to the scope of Work of the Subcontract by Subcontractor will be
prepared by the Subcontractor on a Variation Request form numbered sequentially and
commencing with 001 onwards as per attachment - FORM_.4A2 variation request by SC.pdf.
The Variation Request will be handed over to the Subcontracts Administrator together with the
cost and schedule proposal, all necessary details and supporting documentation. The Subcontracts
Administrator shall check the Subcontractor's contractual entitlement to a Variation and his
compliance with the foreclosure time for Variation Request submittal set out in the Article
"Variations" of the General Terms and Conditions of Subcontract (normally 21 days).
The Subcontracts Administrator shall log the Variation request in a sequential log for
Subcontractor initiated Variations. This sequential log is incorporated into the Computerised
Subcontracts Administration system described in Construction Book 4.
After discussion and agreement on the Subcontractor's proposal with the Supervisor, the
Subcontracts Administrator, the Cost Control Manager, the Site Manager and the Client (in the
case where ABB PA acts for and on behalf of the Client), the Subcontracts Administrator shall
either send the Subcontractor a motivated refusal or discuss the proposal and prepare a Work
Order as per attachment - FORM_.4A3 work order.pdf, stating the charge code as per table 1 and
a clear description of the works.
The Work Order shall be signed by the Supervisor, the Subcontracts Administrator, the Cost
Control Manager, the Site Manager and the Client (in the case where ABB PA acts for and on
behalf of the Client) prior to issue to the Subcontractor for signature and implementation of the
works.
If the Work Order amount exceeds the Site Manager delegation, authorisation will also be
requested from the Project Director.

25/34
GE3
4.2.3. Work orders log
The Computerised Subcontracts Administration system described in Construction Book 4 will
allow sorting of Variation Requests:
• by Subcontract
• by charge code.
4.3. EXECUTION OF WORK ORDER
No Variation work should be commenced by a Subcontractor prior to signature of the Work Order in
compliance with the Variation procedure.
No Variation work resulting from works to be back-charged to another Subcontractor or Supplier
should be commenced prior to authorisation by the said Subcontractor or Supplier according to the
Back-charge procedure (refer also to Chapter 5.1).
It is recalled that commencement of execution of any work by a Subcontractor without a Work Order
signed in compliance with the Variation Procedure will be construed as acceptance by the
Subcontractor that such work does not constitute a Variation.
In order to track works performed under a Work Order and to calculate the final amount of the Work
Order, Attachments to the Work Order will be established as described hereafter.
4.3.1. Lump sum or unit rates work order
Upon completion of the Work Order, the Supervisor will prepare a close out Attachment to the
Work Order as per attachment - FORM_.4A4 unit or LS work.pdf .
This document will be signed by the Subcontractor, the Cost Control Manager, The Subcontracts
Administrator, the Site Manager and the Client (in the case where ABB PA acts for and on behalf
of the Client).
The Subcontracts Administrator shall check the quantities shown on the Attachment.
Each Attachment will be logged on the Work Order by the Subcontracts Administrator.
4.3.2. Reimbursable Work Order
The Supervisor will prepare a daily Attachment to the Work Order as per attachment -
FORM_.4A5 daily time sheet.pdf. He shall check the information shown on these daily attachments.
Upon completion of the Work Order, the Subcontracts Administrator will prepare a close out
Attachment to the Work Order as per attachment - FORM_.4A6 summary time sheet.pdf .
These documents will be signed by the Subcontractor, the Cost Control Manager, The
Subcontracts Administrator, the Site Manager and the Client (in the case where ABB PA acts for
and on behalf of the Client).
Each Attachment will be logged on the Work Order by the Subcontracts Administrator.
4.4. DOCUMENTS DISTRIBUTION

5. OTHER SUBCONTRACT ACTIVITIES [TOP]
5.1. BACK-CHARGES
During the progression of a Subcontract, occasions may arise when work will be required to be
performed for the Subcontractor or the Subcontractor incurs some liability that results in a
Back-charge.
A Back-charge is a cost sustained by ABB PA or the Client for the account of a Subcontractor
or Supplier and charged to that Subcontractor or Supplier. This results from work that is the
contractual responsibility of the Subcontractor or Supplier but is performed by others.
A back-charge may result from:

54. ABB
Page
27/34
GE3
• A request from a Subcontractor to have work performed which is within the scope of its
Subcontract.
• Costs sustained by ABB PA or the Client resulting from a Subcontractor's or Supplier's
operations or deficiency.
• Costs sustained by ABB PA or the Client to correct defective or non-conforming Work,
which a Subcontractor or a Supplier has stated or by its actions has indicated that it was
unable or unwilling to correct.
Prior to execution of any Work which is to be back-charged to a Subcontractor or a Supplier
(Work Order charge code F or local Subcontract), a back-charge notice as per attachment -
B1C2.7A1 backchar ge notice.pdf is to be issued by the Cost Control Manager to the
Subcontractor or Supplier (through the Head office Procurement or Project Manager if
required) as per Construction Book 1 - Chapter 2.7 giving him the opportunity to execute the
Work directly.
5.2. QUANTITY CONTROL
Large changes in the volume of the Work impact the conditions of execution of the Work. The
General Terms and Conditions of Subcontract allow a Subcontractor to request for a Variation
if the change in the Subcontract volume of the Main Work exceeds 35 %. It is in fact
Subcontractor's duty to make such a request for a Variation within 14 days of becoming aware
of the change failing which it forfeits the right to a Variation.
It is anyway advisable for ABB PA to promptly inform a Subcontractor of any such large
change so as to mitigate any adverse impact.
Quantity growth is monitored from the Head office as per Protocole Général book 1 - chapter 8
(Material Quantity Control). The Subcontracts Administrator will be informed of any unusual
changes in the volume of Work by the concerned Head office Engineering departments and will
promptly take adequate action towards the Subcontractor.
5.3. PRORATA ACCOUNT
The implementation shall be decided by the Project Management and the Head Office
Construction Management.
5.4. CLAIMS
5.4.1. Claim Prevention
A claim is a dispute between ABB PA or the Client and a Subcontractor in the form of a
written request by the Subcontractor for additional compensation and/or time extension
resulting from the conditions of execution of the Subcontract that the Subcontractor will try
to demonstrate as being different from the Subcontract conditions.
Under the General Terms and Conditions of Subcontract, a claim has to be submitted by the
Subcontractor just as any other request for additional compensation and/or time extension
under the form of a request for a Variation according to the Variation Procedure and is
subjected to the same conditions in particular those of forfeiture for late submittal.

55. ABB

28/34

The outcome of the claim in particular if it goes to litigation will primarily depend on
substantiation of the facts. Good record keeping is therefore essential to enhance the
chances of success. In order to prepare for a successful defence, it is also essential to
recognise claims situations early. Three good indicators of a claim situation building up are:
• Poor Subcontractor performance
• Higher than expected resource requirements: construction equipment or direct labour
due to low productivities
• Time delays due to drawing or material late deliveries or work fronts availability
• Changes in the sequence of works
The Subcontract administration check-list as per attachment - FORM_.2A4 SC admin
checklist.pdf provides guidelines in the main areas of claim prevention.
It should also be noted that total or partial protection against a number of traditional claims
conditions is provided for in the General Terms and Conditions of Subcontract as hereafter
detailed. It is essential for the Subcontracts Administrator to acquire a thorough knowledge
of the said conditions.
5.4.1.1.Total Protection
The Subcontracts Administrator should adopt a firm stance on the following points:
• Differences in complexity between the Subcontract drawings and the actual project
drawings
• Strikes
• Weather
• Interferences
• Factors out of ABB PA's or the Client's control
• Force majeure
5.4.1.2.Partial Protection
• Differing site conditions
• Disruption
• Out of sequence work
• Delay
• Acceleration
5.4.1.3.Delays and acceleration
Claims are generally submitted as a result of either lower than expected gains or of
losses on a project. These usually result from a combination of late delivery of ABB PA
or Client supplies and services and poor performance by the Subcontractor. It will only
be necessary for ABB PA or the Client to be responsible for minor deficiencies to give
the Subcontractor some justification to its claim and for the Subcontractor to endeavour
to mask its own deficiencies. It will then come down to which party is the most
convincing in its demonstration of the sequence of events and documentation of the
facts.
The Subcontract offers ABB PA or the Client some protection in this respect and
particularly in stating that:

• The milestones stated in the Time Schedule Exhibit under the responsibility of ABB
PA or the Client represent their entire schedule commitment under the Subcontract
• The Subcontractor must demonstrate that the delays of ABB PA or of the Client
have impacted his work front. As far as the work front available to the Subcontractor
is sufficient and allows the achievement of the contractual progress curves, the
Subcontractor can not claim for time extension or acceleration
• Contractual cycles per work item are generally defined in the Subcontract (e.g. 4
weeks between the issue of an IFC drawing for a foundation and foundation
pouring)
• ABB PA may ask at its discretion for a 10% acceleration based on the contractual
curves at no charge.
For this purpose, a "Subcontract progress chart" will be established monthly for each
Subcontract and issued to the Subcontractor showing:
• The "SUBCONTRACT SCHEDULE" progress curve as defined in the General
Terms and Conditions of Subcontract
• The "Work in hand" progress curve
• The actual progress curve
The "SUBCONTRACT SCHEDULE" progress curve is submitted by the Subcontractor
within a number of days - as defined in the Subcontract – from Subcontract signature as
part of its Working Plan and shall be approved by ABB PA. This curve becomes the
contractual progress curve and is the only reference for any time extension or
acceleration claims. The correct definition of this progress curve is a major issue to
ensure the good execution of the Subcontract. This curve should include floats in order
to take in account usual construction constraint and/or delay. It should be considered as
the latest curves. Particular attention should be taken in the interface with the other
Subcontractors in particular if the construction works have been subcontracted per trade
to several Subcontractors.
The "Work in hand" progress curve is established by the Scheduling Manager on a
monthly basis and for the 2 following months. This is in fact the "early progress curve".
The actual progress curve is established through the CPMS software and is the
contractual basis of the Subcontractor's monthly payment.
The last update of the "Subcontract progress chart" produced at project completion will
allow a precise allocation of responsibilities between ABB PA and the Subcontractor in
project delays and will also materialise whether or not acceleration has actually taken
place.
5.4.2. Claim Index
The following index will be used as a basis to classify all Subcontracts filing documents as
defined in chapter 2, for future ease of reference. The Subcontracts Administrator will index
each document in the electronic document base according to this index. This index may be
completed during the project lifetime, although due consideration should be given in that
case to the requirement to revisit already indexed documents.

This index allows retrieving documents according to the subjects covered. Classification by
the Subcontracts Administrator according to this index does not presuppose that ABB PA
accepts in any way the accuracy or veracity of the document contents. It merely indicates
that allegations have been made in the said document by a party relating to the index
subject.
One document may be indexed against several subjects.

6. SUBCONTRACTS CLOSE-OUT [TOP]
6.1. PURPOSE
All Subcontracts must be closed-out in order to ensure that the contractual link between ABB
PA or the Client is severed, save for the Subcontractors obligations of guarantee or at law.
No discussion on a Subcontract closeout will be initiated prior to submittal by the Subcontractor
of its proposed Financial Statement as per the contractual format forfeiting the right to make
any further requests.
6.2. SPECIFIC TASKS
The Subcontract closeout is processed through the completion of the check-list as per
attachment - FORM_.6A1 close-out checklist.pdf. Such completion is governed as follows:
• The checklist is originated by the Subcontracts Administrator when the Subcontract is
near completion. Therefore on receipt of the Subcontractor's "proposed Final Financial
Statement" in full compliance with the Subcontract requirements and format, the
checking of Subcontractor's obligations can be quickly implemented.
• The checklist shall be adjusted for each Project to reflect its particulars and items added
or deleted as applicable.
• The checklist is circulated under the Subcontracts Administrator control to each site
discipline/group for verification of satisfactory compliance with all applicable
Subcontract requirements. If all requirements have been met, the discipline/group
representative signs off for its portion the checklist that is then routed to the next
discipline/group.
• When all portions of the checklist have been signed off, it returns to the Subcontracts
Administrator.
• In case the Subcontractor is exposed to liquidated damages for delay, low progress, or
any other contractual reason, the liquidated damages application form is produced as per
paragraph 6.3.3, the Subcontracts Administrator being in charge of getting all the
necessary signatures.
• Get the Subcontractor PERFORMANCE EVALUATION SHEET as per attachment -
FORM_.6A2 SC evaluation sheet.pdf completed and signed off by the Construction
Manager.
• The Subcontract close out will be prepared at site by the Subcontracts Administrator and
discussed with the Subcontractor (with the Client approval if the contract is for and on
behalf of the Client) in view of reaching an agreement if there are no major problems
and positions are reasonably close.
• If that is not the case, the Subcontracts Administrator will prepare a commented table
showing item by item the respective positions of ABB PA and the Subcontractor. The
Subcontract close out will be negotiated at the ABB PA Head office.
• In all cases, the Subcontracts close out amendment will be signed by the ABB PA Head
office.

6.3. DOCUMENTATION
6.3.1. Close out basic documentation
Before site demobilisation, the following minimum documentation shall be assembled for
each Subcontract:
• Copy of the Subcontract and of all amendments.
• Copies of all Work Orders, back-charges.
• Correspondence to and from Subcontractor
• Minutes of meetings
• Milestones achievement certificates and completion certificates.
• Bank guarantees.
• The completed liquidated damages application form if applicable
6.3.2. Subcontracts with unsettled claims
In addition to the documentation listed in the previous chapters:
• Provide all back up documentation that could be helpful in the claim resolution
such as daily labour reports, weekly staff reports, schedules, photographs,
statements from staff and any other similar evidence.
• Upon instruction by the Site Manager, forward the whole package to the Project
Manager at Head office.
6.3.3. Liquidated damages application
Should the Subcontractor have failed to meet its obligation in terms of performance time or
progress as set out in the Particular Terms and Conditions of Subcontract and as defined in the
Article "Performance time and work schedule" of the General Terms and Conditions of
Subcontract, the Subcontracts Administrator shall upon Work completion and prior to the last
payment(s) prepare a memo indicating fairly the reasons for which the Subcontractor has been
delayed, and its portion of responsibility. He shall circulate the memo together with a "Request
for application of liquidated damages" as per attachment - FORM_.6A3 LD application.pdf.
This request shall be completed and signed by the Subcontracts Administrator and the
Construction Manager and included in the close out file.
The request will be circulated at ABB PA Head office by the Subcontracting Department
Manager to:
• The Construction Department Manager
• The Subcontracting Department Manager
• The Project Manager.
Each of these persons shall give his position in the light of the memo from the Subcontracts
Administrator and from other criteria such as:
• Financial situation of the Subcontractor,
• Possible consequences on the time schedule for other Subcontracts under progress for
the Project or for other projects,

60. ABB

• Rendered services or special efforts made for previous projects for ABB PA,
• ABB PA 's policy vis-à-vis the Subcontractor.
The decision to apply or not liquidated damages is finally made by the Project Manager after
discussion and final advice of the Subcontracting Department, and, when applicable, the Client.
The Subcontractor is notified of that decision and the corresponding deduction is made from the
ABB PA position for the Final Financial Statement of the Subcontract.
7. COMPUTERISED SUBCONTRACTS ADMINISTRATION SYSTEM [TOP]
7.1. PURPOSE
The purpose of the computerised subcontracts administration system is to allow proper
control of actual and expected expenditures of Subcontract activities on site as well as
invoiced amounts.
It is updated permanently and the Monthly Subcontracts Status Summary is sent on a
monthly basis to the Head office Subcontracts Department Manager.
The system is developed on Microsoft Access database.
Refer to the operation manual of the application for details on how to use the tool.
The database is available as an attachment in the Construction Book 4 – Computerized
Procedures.
