1 Scope

1.1 Purpose

This Engineering Procedure provides a consistent and uniform approach for
Estimate Preparation applicable to Saudi Aramco capital projects. It is intended
to be used by all personnel connected with the development and/or review of
estimates.

1.2 Definition

An “estimate” is a key ingredient leading to development of an approved plan,
which can be used for comparison with the progress of the project.

Following are the four (4) types of estimates presented in these preparation
guidelines that are critical to project development and management:

1.2.1 Study Estimate

Study Estimate, sometimes referred to as “Conceptual” or “Order of
Magnitude Estimate”, is primarily developed during the very early stage
of project life cycle. It is often based on limited project data such as
facility type, site location and list of equipment which form the basis for
preliminary feasibility, partial cases, process selection alternatives, site
location and layout studies of planned new projects or expansion of
existing ones. Engineering work is at the initial stage which usually
ranges from 0 to 1%.

It is typically used for studying alternatives aimed at providing options in
establishing the most viable and cost effective solution to project
development and execution necessary for making decisions on possible
future projects.

1.2.2 Budget Estimate

Budget Estimate, also known as “Preliminary Estimate”, is prepared
after major engineering decisions have been made. It is intended to
define the cost of the baseline scope of work for a given project that is
included in the capital plan. The Engineering work at this stage is about
5% complete. Budget estimate is based on the approved Design Basis
Scoping Paper (DBSP) prepared by the Facilities Planning Department
(FPD). (Refer to SAEP-1350)

1.2.3 Expenditure Request (ER) Estimate

This is a detailed estimate supporting the Expenditure Appropriation

Pipe fabrication shop location will be identified whether
at a remote location or at the job site.

f) Electrical

scope, quantities and costs of the following electrical
work relevant to the project, but not be limited to:

Power & Control Cable

Cathodic Protection (Impressed Current Type)
Welding Outlets
Distribution Boards
Relay Panels/Annunciators
Bus Ducting
Electrical Heat Tracing
Miscellaneous Electrical Systems

g) Communication

At a minimum, the communication package will include
the scope, quantities and costs of the following systems,
as applicable:

Fiber Optic System
Switching
Transmission
Premises Distribution (PDS)
LAN (Data)
Mobile Radio
SCADA
Telephone
