Activity. An element of work which forms the basic building block for a schedule/network. There are
different schools of thought on how detailed activity definition should be. A text I browsed recently
argued that too much detail is a waste of time and resources, a case of not being able to see the
wood for the trees. This maybe a valid point, however when my wife and I built our house, we would
not have dreamed of doing so without paying attention to detail, or being aware of what we could
expect for our money. See Task (Project Management, Planning/1.10)
Activity Calendar. An activities working pattern. An activity calendar defines the working and nonworking days applicable for an activity. For example engineers working a staff job in Europe might be
working 7,5 hours per day, 5 days a week, while construction personnel on a site in the desert might
be working 12 hours per day, 7 days a week. It is important to identify the working patterns for
different activities as these parameters will ultimately affect the schedule (Project Management,
Planning/1.10)
Activity Description. A description of the work to be performed under the activity.

the character A in ASCII code is a pulse train made up of 7 bits for the code, plus 3 bits for error
checking. Under asynchronous transmission the character pulse trains are transmitted singly as they
occur (possibly at irregular periods in time), however within the pulse train all bit transmissions occur
at a fixed rate. An example which illustrates this is typing at a keyboard, not all keys are pressed
regularly, however whenever one key is pressed all the bits representing that key are transmitted at a
fixed rate. Confused? You are not alone. See Synchronous (IT, Computing/1.05)

Boolean Algebra. The algebra of logic. An English mathematician called George Boole wrote a book
in 1854 called "An investigation of the laws of thought on which are founded the mathematical
theories of logic and probabilities". In this book Boole described an algebra system now called
Boolean algebra (sometimes switching algebra) for representing and manipulating logical expressions.
Digital computers are designed, maintained, and analysed using techniques based on Boolean
algebra. Variables in Boolean algebra can only assume one of two values, 0 or 1, True or False,
Something or Nothing, Positive or Negative, as opposed to algebra where variables can assume any
value in the range of real numbers. Claude E Shannon first applied Boolean algebra as a method for
representing circuits as a set of mathematical expressions in 1938 (IT, Coding/1.05)

Change. A modification to the scope of work. See Variation (Project Management/1.10)
Change Control. The recording, control, and notification of changes also called Variation Control.
Which ever side of the fence you are sitting on the registering and control of changes is very
important. Uncontrolled changes can be a financial disaster for a project. Quantity surveyors who
register and estimate the cost affect of project changes should not be considered as an overhead, but
as a necessity. In a nutshell changes to the scope of work can be identified by any member of the
project organisation. A project control group should be responsible for verifying that a variation does
exist and raising the appropriate change notification to the Client. The change should be immediately
distributed to the planning department and incorporated into the working schedule, for calculation of
any schedule impact. Changes that are not identified or notified to the Client within a reasonable
time, may be considered to be a part of the contractual scope of work. See DVO, DVOR, PVN, PVOR,

Charpy Test. Metal Impact Test. A test performed on a sample piece of metal to show its resistance
to impact at low temperatures. Most steel plates become increasingly brittle as temperatures decrease
particularly below -20 F. This test is performed on a test coupon which is machined with a v notch or
keyhole cut in one side. The coupon is then frozen to the test temperature and quickly placed in a
clamp fixture, and struck with a pendulum hammer. The hammer is connected to a gauge which
registers the impact resistance of the coupon as it breaks. The resistance is measured in FT-LBS

Conventional Memory. Main Memory. A CPUs storage area for processing. The first 640k of a PCs
main memory is called conventional or sometimes base memory. When PC’s were first developed they
were designed around a main memory size of 640k, a large amount in 1977. A particular chip (CPU)
can only address a given size of memory, for older chips this was 640k, newer chips can address
gigabytes (billions-us). Normally k means kilo or one thousand. The exception is of course computers
where 1k=1024, so 640k=655.360 bytes. For older PC’s Conventional memory was reserved for
storage in the following order, 1) the Basic Input Output System, 2) Disc Operating System, 3)
Drivers, 4) Programs, 5) Data. (I think). See upper memory (IT, Computing/1.05)

Digital Signal. A signal that only has two values during transmission. See Boolean and Analogue (IT,
Telecommunications/1.07)
Digital Signature. Confirmation of the identity of an electronic message sender. In theory a digital
signature is verifiable and non-repudiable, and ensures that the contents of an electronic message (or
transaction) has not been altered. Germany was the first country to pass a law on digital signatures,
(where the digital signature is not legally binding!?). My own views on this matter are that cash can
be stolen, travellers checks can be stolen, and credit cards can be stolen or used without
authorisation. If you deal on a bartering system your cows and goats can also be stolen! At the end of
the day who do you trust and who can rob you during the process of an exchange. As a closing note
smart cards, which are banking cards with a built in chip instead of a magnetic strip, are widely in use
in Europe and contain a type of digital signature called a unique key or unique id which the card is
never meant to reveal. (Has no one ever heard of torture). See SET, PGP (IT, Computing/1.05)

Crosstalk interference occurs when two cables are too close and cause disruption to each other.
Solutions are, move the cables further apart, use twisted pairs, use shielded cable, or fibre optic
cable. RFI is high frequency radiation produced by things like, radios, mobile telephones, computers,
motors. RFI can cause disruption with high speed digital circuits found in computers when for
example the printer parallel cable starts acting like an antenna (IT, Computing/1.05)

of modelling is called object modelling. Object oriented analysis and design assumes a process

ES. Early Start. Early start and finish dates are calculated during a forward pass of the network. If the
first activity starts on day 1 and has a duration of 5 days its ES will be day 1 and it's EF day 5. Any
activities succeeding it will start on day 6. However when the start of an activity is dependent on
more than one preceding activity it's ES date is the maximum EF date of the preceding activities. EF =
ES + Duration. The EF date of the last activity in the network is the expected completion date of the
project. The expected completion date represents the longest sequence of activities in the network,
this sequence of activities is called the critical path. See FS, SS, TF, FF, ES, EF, LS, LF, Network, AON,

computer networks that is available to the public. There also exists smaller internets, usually for the
private use of a single organisation, called intranets. Internet technology is a primitive precursor of
the Information Superhighway, which is a theoretical goal of computer communications to provide
schools, libraries, businesses, and homes universal access to quality information that will educate,
inform, and entertain. Internets allow information to pass between computers, and a variety of
services have been built upon this function. Including logging onto and operating a computer from a
remote location (telnet). Transferring files between a local computer and a remote computer, File
Transfer Protocol (FTP). Reading and interpreting files on remote computers (gopher). The newest
and most important internet service is Hyper Text Transfer Protocol (HTTP), a descendant of the
gopher service. HTTP can read and interpret files on a remote machine, not only text, but pictures,
sounds, and video information. HTTP is the information transfer protocol that is the basis for the
collection of distributed information called the World Wide Web (IT, Internet/1.06)

Leak Test. Pressure Test. Pressurisation of a component by filling completely with nitrogen, or air
and applying an established amount of pressure with a pumping device. All openings must be plugged
or capped prior to test. Normally a pressure and temperature recording chart is hooked up to the test
unit to produce a permanent record of the test. The test pressure and duration must be specified.
Normally a leak test is combined with a soapy bubble test, where joints are coated in a soapy water
solution and visually inspected for bubbles. This type of test is associated with hazardous operations,

LS. Late Start. Late start and finish dates are calculated during a backward pass of the network.
Calculations are started with a completion date, which may be the expected completion date
computed during the forward pass, or a target completion date that is imposed. If the last activity in
the network has a LF on day 10 and a duration of 5 days its LS date will be day 6. Any activities
preceding it will have a LF date of day 5. However when the Late Finish of an activity is dependent on
more than one succeeding activity it's LF date is the minimum LS date of the succeeding activities. LS
= LF - Duration. The LS date of the first activity in the network is the latest date that the project must
start on if the objectives of the network are to be met. If the expected completion date of the project
calculated during the forward pass was used as the LF date of the last activity in the network, then
the LS date of the first activity in the network will be equal to it's ES date. See FS, SS, TF, FF, ES, EF,

Macro. A series of special instructions for a program. Macros enable a user to automate repetitive

Macro virus. A self replicating piece of code written in an application's macro language. Macro
viruses are very easy to create or modify. The distinguishing factor that makes it possible to create a
virus with a macro is the existence of auto-execute macros in the macro language. An auto-execute
macro is one that is executed in response to an event such as opening or closing a file, and not in
response to an explicit user command. Once a Macro virus is running, it can copy itself to other
documents, delete files, and create general problems in a system. These things occur without the
user explicitly running the macro. Macro viruses spread by having one or more auto-execute macros
in a document. Opening or closing the document or using the "replace" command, activates the virus
macro. When the macro is activated, it copies itself and any other macros it needs, to the global
macro file NORMAL.DOT. After they are stored in NORMAL.DOT they are available in all open
documents. At this point, the macro viruses try to spread themselves to other documents, usually by
including an Autoclose macro that attaches the virus macro to the document and saves it. The Macro
viruses that cause damage contain a trigger that starts the damage routines. The trigger is some
event that the virus writer has programmed the virus to watch for, such as a date or the number of
days since the infection occurred (IT, Computing/1.05)

Measure of Capacity. There are three systems of measurement, the British imperial system, the US
liquid measure, and the US dry measure. Liquid and dry goods were once measured using different
systems with varying measures, wine gallon, ale gallon, Winchester bushel, etc. The liquid measures
used in the US today are similar to the now defunct wine gallon. While the standard US bushel (dry
measure) used in the US is similar to the defunct Winchester bushel. The Imperial system for
measuring capacity was established in England in 1824 for measurement of both liquid and dry goods.
The metric system of measurement is a lot easier than these systems but is not as quaint. Eg. "We
downed a hogshead of ale last night", loses a lot in the conversion to "We downed 238,5 litres of pils
last night" (Weights & Measures, Imperial/1.05)

Morgan. Welsh buccaneer. Sir Henry Morgan (1635-88), was born in Llanrhymny. It is believed that
he was kidnapped in Bristol when a boy and sold as a servant on the West Indian island of Barbados.
From there he worked his way to Jamaica, and joined the buccaneers, pirates who preyed on Spanish
settlements and shipping. By 1666 he was in command of his own vessel. Commissioned by the
governor of Jamaica to carry on hostilities against the Spanish, Morgan captured and sacked
settlements in Cuba, Panama, and Venezuela. He was brought to England in 1672 to be tried for
plundering Panama City after a treaty had been signed between England and Spain. Convinced of his
loyalty, King Charles II knighted Morgan and appointed him lieutenant governor of Jamaica. The

difference between a buccaneer and a privateer is that a buccaneer is a state sponsored pirate, whilst
a privateer is a self employed pirate, ie. he is not bothered about the nationality of the ships and
settlements he plunders! Captain Morgan was the most feared and renowned of the buccaneers, he
achieved state recognition for his state commissioned exploits against the Spanish. On the other hand
Blackbeard (an Englishman) was the most feared of the privateers, Blackbeard died a bloody death

OEM. Original Equipment Manufacturer. An OEM (original equipment manufacturer) is a company
that provides a component to another company for use in that company's brand name product. Many
computer hardware manufacturers that have their own brand-name products derive considerable
revenue by reselling the product or key parts of it to companies that seem to be competing in the
same market. Arguments for being an OEM are that you may be able to make money from a market
sector that your competitor already owns (perhaps because they have an existing customer base) and
that you can be a more efficient producer because you sell and manufacture more of your product.
Frequently, a company that incorporates OEM parts or products differentiates itself from the OEM's
brand-name products by adding features or using different selling concepts (IT, Computing/1.05)

Optic fiber. A glass or plastic wire as thin as a human hair, which carries signals using pulses of light
emitted by a laser. Fibre optic cable is not subject to electro magnetic or radio frequency interference,
and is capable of carrying a lot more information than copper wire. Fibre optic cable is constructed of
a core which is the glass in the centre of the cable, and the region through which the light pulses
travel. A cladding which surrounds the core and keeps the light from escaping the core, and a coating
or sheath, which surrounds, protects, and acts as a cushion for the glass fibre. Light travels fast and
digital signals are based on pulses (imagine a Morse code message). A laser can be turned on and off
a billion times per second, and a single strand of glass fibre can carry multiple wavelengths (different
colours) of light simultaneously. See Boolean, Bits, Twisted pair, Coaxial (IT, Computing/1.05)

Orifice Fitting. Any device which allows orifice plate insertion into and removal from a pipeline
without "breaking" the line. May be either a "deadline" fitting (pipe section must be depressurised
before plate removal) or a "liveline" fitting which allows plate removal under flowing conditions. An
orifice plate is used in gas metering runs to measure the volume of gas passing through the run, this
is achieved by measuring the pressure on both sides of the orifice plate, the differential is then used
to calculate the volume of gas transferred. This process is called custody transfer. See SCF

Ribbon. A graphical user interface. With Office 2007 the menu structure has disappeared and has
been replaced by something called the ribbon. What is the ribbon you may or may not be asking
yourself? The ribbon is something called a fluid user interface. Microsoft describe it as “a user
interface that makes it easier for people to get more out of Microsoft Office applications so they can
deliver better results faster”. Well that is bollo*ks it takes me three times as long (at the moment) to
navigate around and search for items. Why could they just not include a classic view!! I used to be
able to say that will take six hours to do, meaning it will take me two hours to do now og away and

SDRAM. Synchronous Dynamic Random Access Memory. Replacement for DRAM. Increases the
bandwidth fourfold. The latest type of PC memory architecture. SDRAM provides a significant
performance improvement over conventional Fast Page Mode (FPM) or Extended Data Output (EDO).
The main difference is that SDRAM is synchronised to the system clock signal, which means that all
operations run at the same speed as the processor bus, compared to conventional memory
architectures which run asynchronously to the processor bus. Due to this synchronisation, data bits
are retrieved faster and thereby increase system performance (IT, Computing/1.05)

Sour Gas (Liquid). Any Gas (or liquid) containing sufficient H2S (hydrogen sulphide) to be
considered sour. Actual amount of H2S is a variable depending on pressure and other parameters.
When a fluid is established as being sour, certain metallurgical considerations are required. One of the
main considerations is that of material hardness. H2S is not as much a corrosion problem as it is a
potential cause of metal failure (Sulphide Stress Cracking). Some metals are more susceptible to SSC
than others. Very small concentrations of H2S when breathed can be Fatal (Petrochemical/1.05)

and estimated man-hours. In addition codes to uniquely number the task and identify it with it's
corresponding activity, location, sub-system, the originator, and whether the task is original contract
scope or varied scope. Quite often the term task is misused to mean activity, when infact tasks are a
breakdown of an activity into smaller packets of work. For example an activity maybe defined as
'Foundation for heat exchanger abc', the tasks for which might be defined as, excavate, lean
concrete, formwork, re-bar, anchor bolts, pour concrete, curing time. See Activity, MTO, BOQ (Project

Twisted pair. Two insulated copper wires twisted around each other, and incased in a sheath or
shield. If the shield acts as a ground (earth) the cable is called shielded twisted pair (STP). If it does
not act as a ground (earth) it is called unshielded twisted pair (UTP). Both wires are required to
transmit a signal. Usually more than one signal needs to be transmitted by a cable, this is achieved by
adding an extra pair of cables. The cable is then denoted as 2 par, or 4 par, etc. Twisted pair uses a
colour coding system, when multiple pairs are used. See crosstalk, EMI, RFI, coaxial, fibre optic, STP,

disciplines, and then into elements of work, like procedures, drawings, studies. Another approach is to
define each work package as a major element of work. For example each module in a North Sea
platform. Each work package is then sub-divided into project phases, and disciplines. There are of
course many ways to skin a cat, and the most suitable breakdown will ultimately depend on the type
of project, and it's complexity (Project Management/1.05)

web pages are the pages in the books. WWW Pages can contain whatever information their creators
want to make available eg, news, pictures, movies, sounds, opinions, company profiles, etc, etc, etc.
These WWW sites can be located on servers anywhere in the world. The analogy with a library ends
when it comes to indexing, you can usually easily find the book you want in a library! See Int A

ACQ. Annual Contract Quantity. (Project Management/1.07)
Activity. An element of work which forms the basic building block for a schedule/network. There are
different schools of thought on how detailed activity definition should be. A text I browsed recently
argued that too much detail is a waste of time and resources, a case of not being able to see the
wood for the trees. This maybe a valid point, however when my wife and I built our house, we would
not have dreamed of doing so without paying attention to detail, or being aware of what we could
expect for our money. See Task (Project Management, Planning/1.10)
Activity Calendar. An activities working pattern. An activity calendar defines the working and nonworking days applicable for an activity. For example engineers working a staff job in Europe might be
working 7,5 hours per day, 5 days a week, while construction personnel on a site in the desert might
be working 12 hours per day, 7 days a week. It is important to identify the working patterns for
different activities as these parameters will ultimately affect the schedule (Project Management,
Planning/1.10)
Activity Description. A description of the work to be performed under the activity.

AOA. Activities on the arrow. Arrow networks are diagrams where the activity is placed on the arrow,
between the nodes. The activities, together with the nodes and dummy activities (activities with zero
duration) represent the sequence in which activities will occur. The nodes for an arrow network are
drawn as circles, and dummy activities, (which act as constraints), are drawn as dashed lines. See
Network, AON, PERT, CPM, CPA (Project Management, Planning/1.08)
AON. Activities on the node. Precedence networks are diagrams where the activity is placed on the
node, and the arrows between the nodes represent the dependencies and sequence in which the
activities will occur. The significant difference from an arrow network is that dependencies of different
types are allowed. Finish to Start dependencies with negative lags, imply an overlap in the activities.
The nodes for a precedence network are drawn as rectangular boxes. See Network, AOA, PERT, CPM,

Baseline. A scheduling benchmark. A Project Control Baseline is the benchmark from which
subsequent schedules are measured against for deviations. The idea of benchmarking comes from the
workshop, where the work bench was marked for measuring purposes. In effect a baseline is a freeze

can be measured. E.g.. schedule acceleration (Project Management, Planning/1.05)

Change. A modification to the scope of work. See Variation (Project Management/1.10)
Change Control. The recording, control, and notification of changes also called Variation Control.
Which ever side of the fence you are sitting on the registering and control of changes is very
important. Uncontrolled changes can be a financial disaster for a project. Quantity surveyors who
register and estimate the cost affect of project changes should not be considered as an overhead, but
as a necessity. In a nutshell changes to the scope of work can be identified by any member of the
project organisation. A project control group should be responsible for verifying that a variation does
exist and raising the appropriate change notification to the Client. The change should be immediately
distributed to the planning department and incorporated into the working schedule, for calculation of
any schedule impact. Changes that are not identified or notified to the Client within a reasonable
time, may be considered to be a part of the contractual scope of work. See DVO, DVOR, PVN, PVOR,

more than one preceding activity it's ES date is the maximum EF date of the preceding activities. EF =
ES + Duration. The EF date of the last activity in the network is the expected completion date of the
project. The expected completion date represents the longest sequence of activities in the network,
this sequence of activities is called the critical path. See FS, SS, TF, FF, ES, EF, LS, LF, Network, AON,

LS. Late Start. Late start and finish dates are calculated during a backward pass of the network.
Calculations are started with a completion date, which may be the expected completion date
computed during the forward pass, or a target completion date that is imposed. If the last activity in
the network has a LF on day 10 and a duration of 5 days its LS date will be day 6. Any activities
preceding it will have a LF date of day 5. However when the Late Finish of an activity is dependent on
more than one succeeding activity it's LF date is the minimum LS date of the succeeding activities. LS
= LF - Duration. The LS date of the first activity in the network is the latest date that the project must
start on if the objectives of the network are to be met. If the expected completion date of the project
calculated during the forward pass was used as the LF date of the last activity in the network, then
the LS date of the first activity in the network will be equal to it's ES date. See FS, SS, TF, FF, ES, EF,

Productivity Factor. A theoretical measurement of effectivness. The ratio of actual manhours
expended to estimated manhours earned. The formula is Productivity=Actual/Earned. If the value is
greater than 1 then productivity is poor, or the estimate is poor, or too little progress is being claimed,
etc, etc. On the other hand if the value is less than 1 then productivity is good, or there is a lot of

Task. An item of work to be performed. A task is a detailed definition of the scope of work and is
related to an activity in a many to one, or possibly one to one relationship. Referenced information for
each task should include a work description, required engineering information, material requirements
and estimated man-hours. In addition codes to uniquely number the task and identify it with it's
corresponding activity, location, sub-system, the originator, and whether the task is original contract
scope or varied scope. Quite often the term task is misused to mean activity, when infact tasks are a
breakdown of an activity into smaller packets of work. For example an activity maybe defined as

WBS. Work Breakdown Structure. A hierarchical definition of the scope of work, where a work
package is an element of the WBS. As with most things a simple WBS works best. A common WBS
breakdown is into project phases, where work packages may be defined as Engineering, Procurement,
Fabrication, Installation, and Commissioning. These work packages might be further sub-divided into
disciplines, and then into elements of work, like procedures, drawings, studies. Another approach is to
define each work package as a major element of work. For example each module in a North Sea
platform. Each work package is then sub-divided into project phases, and disciplines. There are of
course many ways to skin a cat, and the most suitable breakdown will ultimately depend on the type
of project, and it's complexity (Project Management/1.05)
