1. Introduction

1.1 Supervision and contract evaluation system

(1) General concept of supervision and contract evaluation system

The concept of supervision and contract evaluation system is to streamline the cyclic

management process as shown in Fig.1.1 for contracted road works. Through continuous exercise

of this cycle, the system will help Road Authorities supervise and manage road works effectively

and also give Contractors incentive to improve their performance.

This can be achieved by providing transparent and objective “check and record” methods. The

methods cover the key performance and technical requirements for road works and matters such

as safety, environmental and social impacts of the work execution. The latter are becoming more

significant in Kenya and needs careful mitigation actions to avoid any negative consequences

that may arise.

Fig.1.1 General Concept of Supervision and Contract Evaluation System

(2) Operational Procedure

Operational procedure is shown in Fig.1.2.

1) At launching stage, the Contractor submits Works Execution Programme (WEP) that is a

basis for the management of works.

2) During execution stage, Supervision Check List (SCL) is used by the Authority. SCL which is

unified format records the degree of compliance and achievement against performance targets.

The results recorded on SCL are used as a basis for contract evaluation.

3) At conclusion stage, contract evaluation is conducted using an objective method to assess the

overall performance and finished works. The result of evaluation is graded and then converted

to scores. The score is notified so that the Contractor can review their performance.

4) Since the scores are generated in a fair and transparent manner, they can be used as data for

relative comparison between contracts. All the scores derived from contract evaluation are

stored in a database.

5) In subsequent procurements, the database may be referred to by the relevant Authorities,

procurement entities, or any other interested party. A company’s scores in the past would be

taken into account in prequalification and tender evaluation.

1.2 Application of the Manual

(1) Application

This Manual which is administrated by the Ministry of Roads shall be applied to all road

works contracted by Roads Authorities in the Republic of KENYA. Target groups of the manual

are officers in the regional office and headquarters of the Authority who are in charge of the

management of contracted road works. The manual shall be applied to road maintenance,

construction, improvement, and rehabilitation of works.

(2) Relationship with other relevant documents

This manual shall be used in conjunction with other relevant documents as listed below:

1) Statutory Regulations

•Public Procurement and Disposal Act2005

•Public Procurement and Disposal Regulations 2006

2) Contract documents

(•“Guide to the use of FIDIC, Conditions of Contract for works of Civil Engineering

Construction”, fourth edition, Federation international des ingenieurs-conseils, 1987)

(4) Documentation

The following documents are prepared and exchanged between the contractor and the

Authority during the contract period. These documents are all proof material to conduct

supervision and contract evaluation procedures. Fig. 1.3 illustrates the usage of the documents in

the process. The templates of these documents are shown in Appendix B-H.

1) Works Execution Programme (WEP)

2) Site diary (daily report)

3) Monthly progress reports

4) Substantial Completion Certificate (Taking-over Certificate)

5) Notification of Scoring of Contract Evaluation

At supervision stage, the actual work proceedings are compared to the planned one written in

WEP. The comparison is recorded on the site diary confirming whether the works are in

accordance with WEP. The contents in site diary are used to mark and update SCL. That

information on SCL becomes a basis of grading and scoring in contract evaluation. Scores of

contract evaluation are reported to the contractor by the official notification letter and input and

stored in database through RMMS.

2. Supervision

2.1 Supervisors

Supervision is conducted by the following engineers in charge. The degree of checking

frequency and its focus points vary by supervisor.

(1) The Resident Engineer

Based on daily involvement of work management, Resident Engineer in the Regional Office

checks the contractor’s execution of the works by using Supervision Check List (SCL). Resident

Engineer issues a corrective order when the work execution is not in accordance with the

requirements specified in the Specifications and SCL.

(2) The Engineer and Engineer’s Representative

The Engineer usually appoints the Engineer’s Representative (ER) from a department of the

Authority’s headquarters. The ER checks the proceedings of work execution through the reports

from the Resident Engineer, occasional site visits, and progress meetings.

(3) Quality Assurance Office

Targeting the selected number of contract, Quality Assurance Office (QAO) conducts a

technical auditing based on evidences provided in documents. If necessary, QAO shall conduct

site inspections in order to confirm their credibility.

(4) Inspection Acceptance Committee

Inspection and Acceptance Committee (IAC) checks the work performances at the completion

stage to determine the validity of handover of finished product to the Authority. IAC organizes

the substantial completion meeting at site and carries out visual work checks. IAC is required to

supervise works with independent points of view.

2.2 Supervision stages

Figure 2.1 summarizes the process of supervision.

(1) Order to Commence

The Engineer issues an order to commence

(2) Submission of Works Execution Programme

i. Contractor shall submit the WEP by the time that was specified in the contract documents (see

Chapter 2.3)

ii. Submission of performance guarantee shall be within the period stated in the Appendix to

contract for the date from the award of the Authority (the same applied to performance

guarantee guarantees where applicable).

Fig 2.1 Supervision process

(3) Commencement of Work / Site possession

Contractor ensures that commencement date is not later than the period stated in the

Appendix to the Contract.

(4) Daily Inspection

Resident Engineer on a daily basis updates Site diary report to record the work progress. Site

dairy is to be the core source of updating the SCL.

(5) Issuance of corrective order

Corrective order is issued when an activity is not done in accordance with requirements given

in the Specifications and SCL. Whenever a corrective order is issued, summary of the order is

remarked on SCL.

(6) Monthly Inspection

Resident Engineer and contractor carry out monthly inspection in order to determine the overall

monthly progress and update SCL based on the cumulative daily inspection reports. This is the

basis of monthly progress reports discussed and confirmed in the monthly progress meeting.

(7) Monthly progress meeting (Site meeting)

Progress meeting is held on a monthly basis with the attendance of representatives from the

Authority and contractor to confirm the work progress and discuss any challenging issues arising

during the execution.

The meeting checks the degree of compliance with contents in WEP. The meeting also checks

quality and quantity of the works and payment.

(8) Management meeting

Management meetings are called when there are issues that cannot be resolved in the regular

site meetings. It also provides a forum for amicable settlement of disputes between the Authority

and contractor.

(Reference)

2.1) Clause 14.1, FIDIC “Conditions of Contract for Works of Civil Engineering Construction,

Forth Edition”, 1987 (FIDIC)

2.3 Works Execution Programme

2.3.1 Purpose

Works Execution Programme (WEP) is a document in which the contractor describes his plan

of conducting works assigned in the contract. With the preparation of WEP, contractor declares

how the works are implemented within the contract period. Therefore WEP needs to cover all

required information for proper execution and completion of the work.

When WEP is submitted and approved by the Authority, it becomes the official document and

the benchmark of supervision with which the Authority checks whether works are proceeding as

planned.

The Authority should carefully examine the contents of WEP and confirm the adequacy of

WEP through comparisons with standard/special specifications and relevant documents before

approval. Likewise contractor should prepare WEP carefully with no unclear, false or flawed

description or it is disapproved and incompliance is pointed out during the execution.

Note that WEP as referred to in this document is different from the programme of works

described in FIDIC and SSRBC. Therefore it can be said that the programme of works forms part

of WEP.


‐ 11 ‐

Submission of the programmes required in Special specification by referring to Clause14.1 in

FIDIC1987;

“The Contractor shall, within the time stated in Part II of these Conditions after the date of the

Letter of Acceptance, submit to the Engineer for his consent a programme, in such form and

detail as the Engineer shall reasonably prescribe, for the execution of the Works. The Contractor

shall, whenever required by the Engineer, also provide in writing for his information a general

description of the arrangements and methods which the Contractor proposes to adopt for the

execution of the Works.”

Also in the section 104, SSRBC specifies;

“In accordance with Clause14 of the Conditions of Contract Parts I and II, the Contractor

shall submit a fully detailed and time related programme showing the order of procedure and

method in which he proposes to carry out the Works.”

2.3.2 Contents

The contents to be included in WEP are shown in Table 2.1. A sample format of WEP is shown

in Appendix A.1. The definition for the “Scale of Works” in the table is as follows:

Large scale work: a project by class A, B, C and D company

Small scale work: a project by class E and under company

Labour-based work: a project under the Roads 2000 scheme

2.4 Supervision Check List

2.4.1 Purpose

Supervision Check List (SCL) is to oversee the progress of work execution by collating the

degree of achievement of various supervisory points. SCL is prepared in a formatted sheet for

easy data input and recording. Resident Engineer uses SCL for his/her periodical supervision

assignments and a part of progress report. The input is based on site diary. After the contract is

completed, SCL becomes a basis of contract evaluation by Resident Engineer.

2.4.2 List Composition

The followings are components of SCL. Its format is shown in Appendix D.5.2. Table 2.2 is an

example.

(1) Check point

Points to be checked are prearranged in SCL. They reflect various focal aspects to be overseen

during supervision. They are categorized into nine (9) items. Detailed description of each point

and its check timing and frequency are shown in Section 2.5.


‐ 15 ‐

(2) Checking

The date of confirmation needs to be recorded first. Then whether the Contractor’s

performance with each check point is satisfactory or not is recorded in the box. Checking

procedure is written in 2.4.3.

(3) Remarks

Remarks shall be recorded as detailed descriptions of checking results, such as reasons of

dissatisfaction, reference number/date of site diary, record of corrective order (are written as

remarks). Positive remarks about outstanding performance and explanation in case of “Not

Applicable (N/A)” are recommended to be written as a remark.

2.4.3 Procedures

(1) Check Procedure

Except check points that are checked before the commencement or after the completion,

checking using SCL is conducted as below;

1) Resident Engineer (RE) keeps recording on Site Diary through supervision

2) Before a site meeting, RE conducts checking on SCL based on the record on Site Diary.

3) Copy of SCL is inserted into the draft of Progress Report.

4) Check result on SCL is discussed during the site meeting and agreed with the Contractor.

5) If necessary, correction is made on the check result on SCL.

6) The check result is reported from the Engineer to the Employer as a part of progress report.

(2) Recording

RE confirms project name on the SCL and puts date of recording.

If work performance is satisfactory, tick mark is put on the check box ( ). If not, black-out

(■) mark is put. In this case, remarks with date and reference number in dairy report are

written on remarks column. If the check point is not required in the contract, check box remains

blank or N/A mark is put. Fig. 2.2 shows a recording example of Supervision check list.

In this example, a verbal corrective order based on site diary No.122 was given to the

contractor on 21st August. Since the contractor did not comply with the same check point again

in the following month, a written corrective order based on site diary No.150 was reissued on

18th September. Tick mark in the next month on 24th October indicates that the contractor

complied with the order and satisfied the check point on that month.

Even if an issue has been solved before the day of checking, the problem is recorded on the

check list and comments on this situation are clearly written as remarks.

Fig.2.3 shows how to retain the check results and remarks by creating worksheet in a softcopy

of SCL.

(3) Corrective Order

If RE finds an unsatisfactory situation against check points, he/she points out the issue to

contractor. Although corrective order itself can be issued in various forms (e.g. oral, telephone,

text message, facsimile, email and written format), it is required to be recorded on site diary as

shown in Appendix A.2 or attached to it as a reference. Every time corrective order is issued, RE

puts the sequence number of daily record on SCL as a remark.

2.5 Check points

In the following pages, the check points in the Supervision Check List (SCL) are explained in

tables. The tables include the following contents.

(1) Description

It defines what performance is required by the check point.

(2) Check Timing and frequency

It specifies the timing and frequency of checking and recording on the SCL

(3) Reference

It indicates reference materials which dictate the validity of items to be checked. It basically

comes from existing contractual documents, but also it includes a part of contract documents

which is unique to the maintenance works.

(4) Case Examples

1) The cases of giving corrective order

It shows examples of unsatisfactory situation on each check point whereby a corrective order is

subject to be issued as specified in 2.4.3 (3). The RE needs to record that information on Site

Diary (Daily report) and SCL.

2) The cases of giving grade “a” in evaluation

It shows examples of what can be regarded as an “outstanding performance” which is subject to

be judged as grade “a” in contract evaluation by RE. As indicated in Table 3.3 and Fig.3.3, if the

Contractor has not got any corrective order and has been recorded an excellent performance,

grade “a” shall be given for that particular item. The RE needs to record that information on Site

Diary (Daily report) and SCL.

3. Contract Evaluation

3.1 Application

3.1.1 Purpose

The purpose of contract evaluation is to assess contractor’s performance by fair and

transparent methods after completion of works. The result of evaluation is given in the form of

grade and numerical score that is stored in the database for future reference and use where the

contractor has access to the same. All the contracted road works are subject to evaluation using

the same procedures specified in this chapter. This makes database objective and reliable.

3.1.2 Evaluators

Contract evaluation is basically conducted by three evaluators in order to avoid arbitrary

grading and scoring. As shown in Table 3.1, evaluators are assigned according to the subject of

auditing and contract size. And Fig.3.1 is a flow chart for assignment of the third evaluator.

(1) Resident Engineer

Assigned Resident Engineer evaluates work deliveries by close supervision during the contract

period.

(2) The Engineer’s Representative (ER)

It is the original idea that second evaluator's role should be played by the Engineer because

The Engineer is obligated to be the most important person in the supervision who reassesses the

supervision results by Resident Engineer and can evaluate the Contractor's performance with

comprehensive point of view. However, taking into consideration of the large number of road

works, this manual specifies the role can be played by the Engineer's Representative.

(3) Quality Assurance Office (QAO) or Inspection and Acceptance Committee (IAC)

QAO/IAC evaluates the works as third evaluator with independent point of view.

Composition of members of IAC is regulated in clause No.17 of the public procurement and

disposal regulations 2006. In that case IAC chairperson checks and endorses the evaluation done

by IAC. If the authority does not have Quality assurance office, third party evaluation is

conducted solely by IAC.

(4) Temporary Assignment for the Third evaluator

Since current function of QAO is a technical auditing of selected number of contracts, assigning

the independent evaluator’s role solely on QAO is difficult. For the moment IAC, which is

organized for every contract at the completion and includes other members rather than Resident

Engineer and The Engineer, plays QAO’s role if the contract is not subject to be audited. This is a

temporary measure and when the independent technical inspection office is established in the

Authority, it shall have the whole responsibility for this evaluation.

works.

(4) Inspection and Acceptance Committee (IAC)

For IAC, Substantial Completion Meeting is the most appropriate timing for evaluation. At the

meeting all necessary information and documents for evaluation are available and the evaluators

can observe the site for close checks. However, IAC shall ask the Contractor to get out of the

meeting venue during the evaluation in order to avoid the influence by the Contractor.

3.2 Evaluation procedures

3.2.1 Overall procedures

(1) Organisational Scheme

Organisational scheme of evaluation is shown in Fig.3.2.

1) The contractor submits Works execution programme (WEP) before the commencement of the

work.

2) Resident Engineer (RE) checks the contractor’s execution system using Supervision Check List

(SCL) in terms of compliance with WEP.

3) RE checks quality and finished works dimension based on reports from the Contractor.

4) RE evaluates nine items and puts the results on Grading Sheet for the Resident Engineer

whose example is shown in Table 3.7.

5) The Grading Sheet is shown to The Engineer’s Representative (ER)

6) ER evaluates five items and two items for bonus and penalty. ER puts the results on Grading

Sheet for the Engineer’s Representative whose example is shown in Table 3.7.

7) Quality Assurance Office (QAO) or Inspection and Acceptance Committee (IAC) evaluates two

items in CETS. Evaluations are done using Grading Sheet for Quality Assurance Office / Inspection

and Acceptance Committee whose example is shown in Table 3.9(a) – (c).

8) Grading results by three evaluators are input on Contract Evaluation Tally Sheet so that the score is

calculated.

3.2.2 Grading

(1) Definition of grade and basic score

Evaluation results are expressed in five grades as shown in Table 3.2. Basic score is given for

each grade; the scores cannot be intermediate values between basic scores. Hereafter in this

manual, the word “grade” is used for determination of grades “a”, “b”, “c”, “d”, or “e” in a part of

evaluation process.

It should be noted that grading is to be conducted strictly in accordance with Table 3.3 and

Section 3.4 to 3.6. This means that grading shall be done by neither intuition by the words like

“Very good”, “Good”, or “Very poor” nor any percentages implied from Basic Scores of 10.0, 7.5,

5.0, 2.5, or 0.0.

(2) Grading Criteria

Determining grade which corresponds to the level of contractor’s performance is the core part

of the evaluation process. Table 3.3 summarizes the grading criteria. Detailed procedures are

described in Chapter 3.4 to 3.6 by type of evaluator.

3.3 Evaluation items

There are 11 items for evaluation. Note that evaluation items 1 to 9 are identical to the items

in Supervision Check List (SCL). Each evaluation item contains one or two sub-items. Not all

sub-items are to be evaluated by each evaluator; sub-items to be evaluated are varied by scales of

the works as shown in Table 3.4.

The definition of scales of the works is the same as in 2.3.2; Large scale work is a project by

Class A, B, C, and D company, Small scale work is a project by Class E and under company, and

Labour-based work is a project under the Roads 2000 scheme.

3.5 Evaluation by the Engineer’s Representative


The Engineer’s Representative is responsible for overseeing contracts’ general performances

from many aspects. The Engineer’s Representative (ER) evaluates the following common items;

(1) Grading


3. In-house staff


7. Work scheduling



(2) Bonus/Penalty

10. Innovation effort

11. Compliance with statutory requirement

(3) Variation of items by scale of the works

Set of evaluation items varies by scales of the works as shown in Table-3.4. The definition of

the scale of works is written in 3.3. Grading items 2, 3, 4 and 7 are evaluated or not evaluated

depending on scale of a work. Grading items 8 and 9 are evaluated in either scale of works. Item

10 for bonus is evaluated for large scale works only, while Item11 for penalty are evaluated in

either scale of works.


(1) General

Since the ER does not follow the daily situation of the contract, the evaluation basically relies

on the grading results by Resident Engineer (RE) and his/her comprehensive examination by

using occasional site checks at monthly progress meetings. Especially The ER shall focus on

identifying the unforeseen difficulties during the work execution and outstanding outcomes of

finished works.

As shown in the Fig.3.4, if RE chooses grades “a” or “e”, The ER gives the same grade

automatically. Otherwise The ER normally gives grade “c”. In case The ER identifies that the

Contractor overcomes unforeseen difficulties or makes an outstanding achievement during the

execution or in the finished works, grade “a” can be given.

Upgrading from “c” to “a” cannot be applied for the evaluation in which the RE plays The ER’s

role. This is the case 3 in Table 3.1 in which the contract is not audited by Quality Assurance

Office (QAO) and the contract sum is smaller than 2,000,000Ksh.

3.6 Evaluation by Quality Assurance Office / Inspection and Acceptance committee


As the independent evaluator, QAO/IAC deals with the two key items which indicate the

contractor’s capacity to deliver;

1. Execution system in general

“Overall system of execution is confirmed to be proper during audit or at

substantial completion meeting”


“Measured parameters are within the specified allowable ranges with proper

workmanship”


Based on temporary assignment of independent evaluator (see 3.1.3(4)), grading entity is

designated as shown in Fig. 3.5. Grading by QAO shall be based on their own investigation and

on written documents about overall system of execution and measured parameters of quality and

quantity management. Grading by IAC shall be based on the results of Substantial Completion

Meeting.

In case Resident Engineer evaluates, grading is based on the check list and his/her knowledge

of works.

(1) Grading criteria for “Execution system in General”

Table3.6 shows an example of grading for “Execution system in General”. The blank format is

in Appendix A5.4. If the Contractor does not comply with the corrective order issued on status of

the system, grade “e” is given. If the correction is poor, grade “d” is given. In other cases, Grading

“a” to “c” is determined according to the number of checks in the sub-table.

(2) Grading criteria for “Quality and Quantity Management”

The level of quality and quantity achievements is judged by the following sub-items. They can

be evaluated by QAO/IAC only with written reports and visual inspection of finished works.

i) Quantity measurements

ii) Quality measurements

iii) Workmanship

As shown in Table3.6, points are given for each sub-item according to the degree of satisfaction

with fixed benchmarks. The criteria of point rating are shown in Table 3.7. The points are

summed up and the total point determines the grade. Weight allotment for each sub-item is 3.0,

3.0, and 4.0 respectively..

i) Quantity measurements

Sub-grades “a’ to ”e’” are determined whether or not the all necessary size and volume

measurements are conducted and recorded as specified, and all measured figures are within

specified allowable range. And the corrective actions of failed results if any are also checked.

ii) Quality measurements

Sub-grades “a’ to ”e’” are determined whether or not the all necessary material testing and

structural checking are conducted and recorded as specified, and all measured figures are within

specified allowable range. And the corrective actions of failed results if any are also checked.

iii) Workmanship

Sub-grades “a’ to ”e’” are determined by the number of satisfactory visual check points specified

in Table 3.9(c). Table 3.8 below shows sample pictures for the check points

3.7 Weighting

3.7.1 Concept of weighting

In order to reflect relative differences of importance between evaluation items and of degree

evaluators’ responsibility, relative weights are used on tallying of scores.

3.7.2 Weight application for scoring

Net score for an item by an evaluator score is calculated as the following equation;

p = w1 x w2 x p0

Where, p : net score, w1 : inter-item weight, w2 : weight by evaluator

p0 : basic scores defined in Table3.2

3.7.3 Inter-item weight

Set of inter-item weight is provided by scale of contract. Table 3.10 shows the weighting set for

the contract of large scale works (for Class D and above company), the contract of small scale

works (for Class E and under company), and labour based work contract.

3.7.4 Weight by evaluator

Weights for Resident Engineer, The Engineer and QAO/IAC are 0.5, 0.3, and 0.2 respectively.

They are reflecting the relative importance of regional office which can objectively evaluate the

contractor’s performance with the most frequent observation of work performance and site

conditions.

3.7.5 Weight change

Weights specified in this section are not subject to change for the validity of unified scoring

scheme. However, when the clear changes of social, economic, environment, technological

requirements are observed, weight setting can be updated with unanimous agreement among

relevant organizations.

3.8 Contract evaluation scoring

3.8.1 Contract Evaluation Tally Sheet

Based on the results on three grading sheets (Table 3.5, 3.7, and 3.9), scores are automatically

given for each item by each evaluator. Contract Evaluation Tally Sheet (CETS) is the unified

template to calculate the total score from these scores. Fig 3.6 shows part of the CETS. An

evaluator fills the blank by choosing a “Net Score” which corresponds to the grading for the item

and the evaluator. There are three formats of CETS for large scale work, small scale work, and

labour based work.

Table 3.12 shows CETS for large scale works. They also include basic contract information and

fixed weights by contract size.

After the calculation of total score, CETS shall be signed by The Engineer.

Table 3.11 is a rough standard of contract’s performance judging from the total score.

3.8.2 Notification of score

The authorized total score and its breakdowns are notified to the Contractor as an official

letter from the Authority. The format is shown in Appendix G. The contractor can raise questions

on the results of scoring within a specific number of days after the issuance. The Authority

answers in writing to the Contractor.

3.8.3 Score database

Every score along with basic contract information and the type of work conducted are stored in

the unified database without delay. The procedure is depicted in Fig 3.7. Input data from each

Authority is rearranged to be a list of companies which contains information shown in Table 3.13

so that scores of any company can be easily extracted. Detailed example of database format is

shown in Appendix 8.1 and 8.2. Database is accessible to any authority in the next procurement

process. It is used as a reference of past experiences of similar type of works in the tender

evaluation stage.
