SITE
SUPERVISOR
The role of a site supervisor generally involves the management
and supervision of a construction site in accordance with
health and safety guidelines. It is the responsibility of the site
supervisor to assess hazards, determine risks, conduct regular
inspections, and maintain a safety programmer.
The site supervisor will typically work closely with the site
foreman, who is responsible for organizing construction works
on site, and report to the project manager.
Site supervisors should have relevant experience in
construction or civil engineering, as well as appropriate health
and safety training.
The responsibilities of a site supervisor may include:
Supervising workers, subcontractors and work activities. 55
Preparing and presenting site inductions, safety briefings
and toolbox talks.
Assessing and managing safety hazards.
Ensuring appropriate site rules and welfare facilities are in
place.
Carrying out regular inspections.
Helping project managers to plan the work programme.
Helping co-ordinate deliveries of materials, plant and
equipment.
Completing records for site reports.
Attending site management meetings.
Carrying out regular inspections to ensure compliance with
relevant legal requirements, processes and procedures.
Raising safety concerns at the appropriate level.
Resolving problems and implementing improvements.
Organising and overseeing external inspections, such as
with a health and safety inspector.
Providing emergency first aid if required.

Example represents a project's bottleneck. The reduction
of the total execution timeframe will only be
possible if the activities on this path can be
shortened, since the time necessary to execute
non-critical activities does not affect the
project's total duration. The habit of
accelerating all project activities in order to
reduce the total timeframe is therefore
unnecessary. Decreasing the duration of one or
more critical activities, can reduce the project's
total timeframe; but it may also change the

PROJECT
QUALITY PLAN
The term 'quality assurance' describes a set of planned,
systematic actions to ensure that products and services comply
with specified requirements. It not only involves checking the
final quality of products to avoid defects, as is the case in
quality control, but also checking product quality in a planned
way through all the production stages. It is the development of
work and product design procedures to prevent errors from
occurring in the first place, based on planning, backed up by
quality manuals and tools.
A project quality plan (PQP), sometimes referred to as a quality
management plan, quality assurance plan or project quality
management plan, is a project-specific quality plan that
describes the activities, standards, tools and processes
necessary to achieve quality in the delivery of a project.
It is sometimes considered to be interchangeable with the
project execution plan (PEP) which sets out the overall strategy
for managing the project, describing who does what and how,
and defining the policies, procedures and priorities that will be
adopted.
RIBA suggest that the PEP or PQP helps track and control
projects which can progress erratically and intermittently and
should pass the ‘what happens if ‘Fred’ is knocked-down by a
bus’ test, describing the project and processes in such a way
that competent people could take over the project and
maintain the program, service and performance.
However, on large projects, the project execution plan might 66
be an overarching document that includes (or references) a
number of more detailed plans focusing on specific issues such
as; the project quality plan, health and safety plan, risk
management plan, value management plan, stakeholder
management plan, and so on.
TOPIC 4
// INTERACTIVE REPORT 2021
The project quality plan should:
Provide explanatory text describing the nature of the
project and the quality expectations.
Set out the organisations quality policies (for example, if
they are ISO 9001 certified) and how these policies will apply
to the project.
Identify other quality criteria or policies that may need to be
followed, such as the requirements of clients or funders.
Describe how quality requirements will cascade down
through the supply chain.
Describe the activities necessary to deliver the project and
the order in which they will be carried out.
Describe the resources required.
Set out quality roles and responsibilities.
Identify the standards that will apply.
Describe monitoring and reporting procedures and the
process for delivering continuous improvement.
Describe procedures for dealing with defects.
Describe document control procedures.
Describe change control procedures.
Set out any training requirements.
Schedule tools that will be used.
List reference material.
Some of these elements may be common to all projects,
however, the PQP should not duplicate information that is
available elsewhere (but rather should reference it), and it
should be project specific, rather than an a generic box-ticking
exercise.

INTERIM CERTIFICATE AND
PROGRESS PAYMENT
Interim certificates provide a
mechanism for the client to make
payments to the contractor before the
works are complete. The Housing Grants,
Construction and Regeneration Act,
states that a party to a construction
contract in excess of 45 days is entitled
to interim or stage payments.
Interim payments can be agreed in
advance and paid at particular
milestones, but they are more
commonly, regular payments, the value
of which is based on the value of work
that has been completed (this is the
actual value of the work completed,
taking into account variations, etc.).
The amount of these payments is
entered onto an interim certificate
(generally valued by the cost consultant,
perhaps having taken advice from the
lead designer) and the client must
honour the certificate within the period
stipulated by the contract.
If the client intends to pay a different Interim certificates should make clear the

(CNC)
The date for completion of construction
works is generally set out in the contract
particulars. However, it is not
uncommon for delays to cause the
completion date to be missed, that is,
the works are not complete, and so a
certificate of practical completion
cannot be issued by the date for

granted, the completion date adjusted,
and the contractor may be entitled to

EXTENSION OF TIME AND
LIQUIDATED ASCERTAINED DAMAGE
Contracts generally include a clause
making provision for the contractor to
pay liquidated damages (LD, sometimes
referred to as liquidated and ascertained
damages - LADs) to the client in the
event that the contract is breached. In
building contracts, liquidated damages
usually relate to the contractor failing to
achieve practical completion (i.e.
completing the works so they can
handover the site to the client) by the
completion date set out in the contract.
They are often calculated on a daily or
weekly rate.
Liquidated damages are not penalties, As liquidated damages are not a penalty, they

If the contract prevents the client
claiming liquidated damages, or if actual
losses are significantly different to those
that were estimated at the time the
contract was entered into, then the
client may pursue a claim for
unliquidated (i.e. actual) damages
through the courts. Unliquidated
damages are damages, the exact
amount of which has not been pre-
agreed, and are typically determined by
the courts.
DEFECT LIABILITY PERIOD (DLP)
Once practical completion has been
certified, the defects liability period
begins (now called the 'rectification
period' in Joint Contracts Tribunal (JCT)
contracts). Typically, the defects liability
period is six to twelve months.
During this period, the client reports any
defects that arise in the works to the
contract administrator who decides
whether they are in fact defects (i.e.
works that are not in accordance with
the contract), or whether they are
maintenance issues. If the contract
administrator considers that they are
defects, then they may issue instructions
to the contractor to make good the
defects within a reasonable time.
At the end of the defects liability period, When the contract administrator considers all

CERTIFICATE OF COMPLIANCE AND
COMPLETION (CCC)
Who is reponsible for issuance of the
CCC?

The PSP must be registered with their
respective boards under the law relating
to their field, such as the Architects Act
1967 or Registration of Engineers Act
