2. It provides a structured method of
obtaining reliable fixed price bids
where limited design definition is
available. Our extensive in-house
database of fabrication Quantities,
Norms and Pricing information for
Onshore and Offshore projects is
coupled with pricing data from all
major fabrication locations globally
including Europe, Gulf of Mexico,
Middle East and Asia Pacific.
The system also provides a detailed
method of measurement and pricing
preambles for each unit rate and
boq item. The tender process can
then be carried out on modeled
information at a very early stage in
the design cycle, determining fixed
pricing structures with fabricators
and providing accurate estimates of
out-turn fabrication cost.
boqsor™ provides a powerful tender
evaluation tool and the ability to
run “what if” sensitivity scenarios to
evaluate the impact of growth on
the relative tenders. As the design
develops Quantity information can
be updated and replaced throughout
the life of the design through to the
“as-built” stage. Interfaces between
boqsor™ and the design information
in design information in PDMS or
3D model can provide a Semi-
Automated Measurement process,
reducing time and manpower in
capturing Quantity Data.
Historical data from previous similar
projects on outturn quantities to

A robust tender evaluation tool
that can process and capture large
amounts of pricing data from tenders
and provide detailed comparison
reports in a very short period of time.
A reliable basis for awarding contracts
and managing them commercially
throughout their duration
A mechanism for managing changes
during construction
A method for calculating progress
payments
The delivery of these services
is system driven with particular
emphasis on our two flagship
software packages boqsor™ and
b-est™. boqsor™ is a powerful
bill of quantity and unit rate
contracting tool and b-est™
provides accurate cost estimating
for major capital projects in the
industry.
boqsor™ can be used to support
the administration of unit rate
re-measurable contracts
throughout their lifecycle from
initial estimates, bid preparation,
electronic tendering and
evaluation, contract award and to
monitor and price the work post
contract.
b-est™ uses man-hour norms
from all of the global fabrication
locations along with access to
the boqsor™ as-built quantity
database to provide detailed class
I, II and III estimates for major
capital projects both offshore
and on-shore within the energy
industry

OGCS Global provides a complete Contracts and Supply
Chain Management Service, which includes Contracts
Engineering, Quantity Surveying, and Project Controls
to the Global Energy construction industry, with specific
focus on the Upstream Oil and Gas sector.
Our boqsor™ software package is a Unit Rate Contracting system
designed for producing Bill of Quantities and Schedule of Rates
specifically for the Oil, Gas and Energy sectors.
Introduction About boqsor™
The system provides

3. The original boqsor™ system was
developed during the early days of the
Oil and Gas industry in the UK North
Sea for the Commercial Management of
large scale Offshore Fabrication Projects.
This innovative concept was prompted
by the demand for a structured
approach to obtaining reliable fixed
price bids when little design definition
was available.
boqsor™ was the basis for the
benchmark publication “Spons –
Fabrication Norms for Offshore
Structures” which became the industry
bible in the 1980’s and 90’s for
estimating, tendering and commercial
administration of offshore fabrication
contracts. The structure and principles
developed by boqsor™ now form
the basis of most other software
applications in use within the industry,
yet it still retains its pedigree and
position as a market leader.
Today, continual development,
innovation and improvement mean that
boqsor™ is the Unit Rate Contracting
and Estimating package for the new era
of Global Fabrication Projects.
boqsor™ has been designed to interface with PDMS and most 3D design
model systems to efficiently harvest and apply cost codes to quantity
data as the design develops. Quantities are “measured” by discipline
and the flexibility of the boqsor™ system allows allocation of quantities
into a pre-developed Work Breakdown Structure (WBS) which can be by
module, deck, level, area etc. The WBS is designed to mirror the project
structure to provide information to seamlessly feed into the project
cost reporting systems. This interface provides a significate cost and
man-power saving over the traditional quantity measurement activity.

boqsor™ history
OGCS has an extensive in-house database of fabrication Quantities across
all types of construction including Jackets, Topsides, FPSO’s FPU’s, Subsea
and Onshore Plants which can be modeled to produce accurate bills of
quantities where little or no design information is available.

4. It allows various levels of class
estimate to be prepared and refined
as more project engineering
information becomes available.
b-est™ has access to an extensive
library of historical out-turn quantity
data from global projects both
onshore and offshore as well as
man-hour norms for all major
global fabrication areas including
Gulf of Mexico, Far East and Korea,
Middle East, Northern and Southern
Europe.
With access to this unique set of
data, from projects similar by type
and/or location, coupled with the
extensive in-house experience
of OGCS personnel, accurate
estimates can be produced at all
levels of detail.
The b-est™ system is structured
to roll seamlessly up or down
between Class I, II or III estimates
as better definition on the project
design becomes available. The
system can therefore be utilised at
any point in the project lifecycle
from conceptual estimates at pre-
FEED, through the Detailed design
Phase and into Construction and
Execution
OGCS utilises man-hours in the
preparation of estimates because
in the very competitive world
fabrication market there can be
extreme price volatility whereas in
our experience hours to execute
work tend to be stable. Once the
man-hour content of the project
has been established then the most
appropriate commercial rates can
be used.

About b-est™
The boqsor™ estimating module b-est™ facilitates construction cost
estimates of Capex developments for major oil and gas projects.
b-est™ and boqsor™ are designed to interface seamlessly between
front end project estimating, a unit rate contracting model, electronic
tendering and tender evaluation and post contract administration and
management. Work Breakdown Structures can be structure to provide
consistency throughout these phases of the project and feed cost and
quantity data to the project and the project reporting functions

5. boqsor™ is an extremely powerful
tender evaluation tool. Once
the electronic priced schedules
are received from all the bidders
they are a loaded into the tender
evaluation module. boqsor™ can
then run detailed analysis and
comparison on a rate by rate basis
across all bidders highlighting where
an individual rate varies significantly
from the average or from the lowest
rate identifying rogue rates or
strategic bidding. Pre-determined
growth sensitivity scenarios can also
be run to identify the impact that
quantity chage (sp) +/- may have on
individual bids.
OGCS hold extensive in-house data
from previous projects providing
detailed Bills of Quantities across all
facilities including Jackets, Topsides,
FPSO, FPU and Subsea Equipment.
For new projects where little
design definition is available these
model bills can be manipulated
to become project specific using
key information such as weight
reports, P&ID’s, piping line lists,
specifications etc
Once the agreed project specific
schedules of rates and bills of
quantities have been incorporated
into the tender documents they can
be issued electronically to bidders
either with the boqsor™ tender
module or in excel format. Bidders
price all items within the schedules
both with manhour norms and
currency values. This automatically
prices the linked bills of quantities to
provide the tender value.
the approximate bills of quantities
can be updated at strategic points
within the design process at AFC
and ultimately to reflect the as built
scenario. At all times the system will
automatically apply the fixed unit
rates to provide an updated contract
price. There are options within
the system to calculate progress
payments and any Variation Order
can be evaluated as a “mini bill
of quantities” priced at the unit
rates. boqsor™ will support all
commercial aspects of the project
through to final account.

Unit Rates
boqsor™ Functions & Capabilities
boqsor™ holds a library of discipline
unit rates that over the years have
become the standard commercial
breakdown structure within the oil and
gas industry. These rates can be modified
to be project specific and to cover
every possible eventuality that may be
encountered within a particular project
as the design develops. Each unit rate
will come with its own detailed method
of measurement and pricing preamble
which advises bidders exactly what cost
categories should be included.
In addition to quantity data OGCS
also have current unit rate norms and
pricing information from all the major
oil and gas fabrication locations globally
including Northern and Southern Europe,
Gulf of Mexico, Middle East, Asia Pacific
and Korea. Once an acceptable model
bill of quantities has been developed this
can then be populated at the detailed
level with the relevant unit rates and
norms to provide reliable conceptual and
bid check estimates.

6. The scope of the project is broken
down, discipline by discipline,
into each work unit activity. These
activities are tabulated in a grid
format which should cover every
eventuality that maybe anticipated
within the design.
The Unit Rate Schedules are priced
on the basis of completion of a
quantity of one by the contractor.
That may be metres of pipe or cable,
number of welds or terminations.
Each item in the bill of quantities
has an 11 digit code which extracts
the description and the rate directly
from the unit rate library and
automatically provides a priced bill
of quantities
As well as the currency rate the
contractor also provides the
manhour norm for each schedule
item so that the bills of quantities
can also be “priced” in manhours
and linked to the schedule for the
project
