3 D MODEL USAGE
The utilization of 3-D modeling in project development
has indeed become indispensable, offering a lot of benefits
across various stages of the project lifecycle. Some break-
down of the key advantages are:
• Minimization of rework and material surpluses: 3-D
models allow for detailed visualization and coordi-
nation before construction begins. This helps iden-
tify potential issues early on, reducing the need for
rework, minimizing material wastage, preventing
costly delays and rework during later stages of the
project.
• Coordination between project participants: The 3-D
model serves as a centralized platform where clients,
engineers, constructors, and maintenance teams can
collaborate and coordinate their efforts efficiently.
• Visualization of engineering evolution: Group model
reviews provide an opportunity for clients and proj-
ect team to track the evolution of the project in an
easy way. This helps ensure that everyone is on the
same page regarding the project’s progress and design
intent.
• Interdisciplinary coordination: Internal model
reviews between different design groups will help to
identify and resolve interdisciplinary interferences,
promoting coordination between all the project
components.
• Real-time design capabilities: Advanced 3-D mod-
eling programs enable real-time collaboration and
design updates, allowing client and engineering team
to work on different aspects of the project simulta-
neously. This enhances efficiency and reduces turn-
around times.
Overall, the integration of 3-D modeling technology into
project development processes offers significant advantages
in terms of efficiency, coordination, and problem-solving,
ultimately leading to improved project outcomes and
reduced costs.
CONSTRUCTABILITY AND ADVANCED
WORK PACKAGING
Early engagement of construction in the design of projects
is a key activity that Bechtel undertakes on all of its proj-
ects. The interaction in the sequence of building of projects,
along with material movement and components is critical.
The Advanced Work Packaging (AWP) process is a con-
struction driven, structured methodology of project execu-
tion that allows the planning and the achievement of the
most expeditious and cost-effective installation of the work
at the project site. AWP starts with the identification of exe-
cutable scopes (“Installation Work Packages”) of work dur-
ing early stages of project design. These scopes of work are
then sequenced and prioritized according to the construc-
tion execution plan. Driving these well-defined/discreet
scopes of work and priorities to design and procurement
early in a project allows for the organizing and delivering of
all necessary information and material deliverables before
construction work is started. Having very complete inven-
tories of materials and complete, fully executable designs
enables the craft teams to perform quality work in a safe,
effective, and efficient manner.
The AWP process provides a means for Startup and
Construction to influence design and procurement activi-
ties early in the project life cycle such that the Engineering,
Procurement, Construction, and Startup are all aligned to
the overall project objectives. Startup and Construction
envisage “Precisely What Do We Want To Be Our Sequence
Of Completion And Turnover Of This Project?,” and with
that end in mind they develop an execution sequence that
will drive the sequence of all upstream Engineering and
Procurement activities.
CONSTRUCTION SCHEDULE
Schedules are a result of comprehensive planning which
must consider contract requirements, scope, budgets, expe-
rience, risks, among other.
The project schedules are developed in accordance with
a hierarchy in increasing level of detail:
• Level 1
– Management Schedule
– Contract Management Schedule
• Level 2
– Project Facility Summary Schedule
• Level 3
– CPM Schedule (Engineering, Procurement and
Construction Logic Schedule).
• Level 4
– Engineering Progress and Performance Report
(EPPR), Material Procurement Report (MPR),
Detail Construction Schedules (3-week look ahead
schedule, etc.)
Careful planning takes places in the early study phases all
the way through to execution planning. The highlighting
of the critical path items allows early planning and procure-
ment of the log lead items such as the primary crusher, mills
and electrical transformers and switchgear. Mobilization
and planning for the early works activities needs to be at
the forefront of the overall plan.
