This document discusses using BIM and an integrated project control system to improve construction project controls. It defines BIM and outlines CCC's approach, which links 3D models, estimating, planning, document management, materials management, and quality systems. The methodology uses object-based modeling, work breakdown structures, integrated schedules, early partnering, look-ahead planning, and links data between functions like estimating and planning. It provides examples of model authoring standards, naming conventions, estimating against models, assigning operations to activities, and generating 4D reports and progress visualizations to improve project controls using an integrated BIM-based approach.

4. DEFINITIONS: BIM
• BIM is often misunderstood and the focus has mainly been on the 3D
models and multi-discipline coordination of design information.
• The "I" in BIM is the real benefit but in the same time the biggest
challenge.
• CCC has used 3D/BIM based tools and linkages to build up its new
Integrated Project Control System. Below is the summary of
methodology that helped us achieve our objectives.

5.  Reliant Pull-Driven Technique optimize supply chain rather than sub optimization
 Assure availability of resources before start of activity.
 Emphasize productivity through the full work chain vs. individual activities
 Prevent sub-optimization
 Partnering
 Proper Project Work Breakdown Structure
 Project/Area/Sub-Area/Fragnet/Activity/Object/Operation
 Integrated EPC schedule with Emphasis on Handover and Construction Activities.
(effective supply chain)
 3D model built with WBS in mind and used as primary scope management tool.
 Early on Cooperation with the Partners/ EDI definition.
 3 Month Look Ahead Schedule/ Material forward plan
 3 weeks Look Ahead Schedule

24. OBJECT NAMING CONVENTION
To make a more effective use of the BIM in construction, the idea of Object based BIM was introduced. A unified
automated coding system was developed for the different disciplines (Structural / Architectural / MEP).
We define an object as “The reasonably smallest portion of a building that reflects the logic of construction,
facilitates the transfer of work between the different crews and can be reported in progress or QS (Quantity
Surveying) reports”. For example a column, a beam, a room finish, a diffuser, a fan, an electric socket…etc)

FRONT END LOADING
• Define Work Package/ Front
• List all required Drawings, Material, and prerequisite
activates such as scaffolding.
• Assign Lag times and responsible supervisor
• Periodic meetings to assess readiness
• When all constrains are resolved, declare work-front
constructible. FEL

44. LOAD WORK-FRONT ON LEAN BOARD.
•Develop Fragnet for all type of objects of work front
•Load Work-front on Lean Board
•C3D loads all work front objects and their operations into Lean board.
•C3D will assist user defining a set of crews to execute the work front using OBS.
•C3D will assign operations to crews based on discipline sub-discipline and crew
production capacity.
•C3D will try to optimize usability of crews, i.e. keep everybody bust and
productive.
•As one work front is consumed, another is loaded and completed work fronts are
archived.
C3D LEAN BOARD
Defining Subcontractors and Crews in C3D

45. ISSUE WORK-ORDER ON LEAN BOARD.
• C3D plans 3 week look ahead schedule and issues daily work orders/cards to supervisors
• C3D receives progress/completion reports using bar codes, digital pen ..etc…
• C3D notifies each foreman of the next operation that can be started as per takt plan.
• C3D receives Data from Time sheet system, consumed man-hours by crew
• C3D issues relevant AFIs and QC forms completed objects/operations during the current
week.
• C3D will issue comprehensive set of reports, graphical and data at the end of every period to
cover all KPI needed by project staff.

46. WEEKLY BUDGETED COST PROGRESS REPORT

47. WEEKLY THREE WEEKS LOOK-AHEAD REPORT

48. 3D Model Colorizations based on the Actual Progress imported in C3D

49. C3D PROGRESS COLORIZATION BY SYSTEM
C3D colorization method can visualize the actual progress percentage on each system.

50. AUTOMATED PAYMENT CERTIFICATE
• C3D collects all progress achieved during the current period
• C3D utilizes BOQs assigned to operations and rules of credit to calculate
gross payment for this period
• C3D allows Quantity Surveyors to check, adjust and add non-modeled
data payments to the system
• C3D summarizes payments to the level of bills and BOQ, but maintains
link to object level BOQs as backup for payment certificate.
• C3D adds calculations for retention, Vat , etc.. As needed.
• Payment certificate issued

51. PROCUREMENT/ SUPPLY CHAIN MANAGEMENT BACK UP
• C3D creates a 4D that outlines expected delivery quantity
per month for all types of material.
• C3D allows the material Engineer to enter suggested lag
time.
• C3D sends summary of register to procurement system
and keeps an updated (schedule updates) to be used in
Material Forward Planning (3 month look ahead cycle)

52. SUBCONTRACTOR CONTROL
• C3D allows contract admin to define subcontractor register.
• For each subcontractor, one or more PO is filled with BOQs and subcontract rates as
agreed.
• Contract admin defines the scope of subcontractor, by linking the PO to the full project or
a sub project (WBS element) as agreed (1out of 3 buildings) i.e. rebar contractor will only
cover 1 building out of 3.
• Within the selected project/sub-project, C3D finds all object/operation that have a BOQ
responding to one of the BOQs in the subcontract PO.
• C3D summarizes quantities of all BOQs to update total quantities and forecast cost for the
subcontract.

53. SUBCONTRACTOR CONTROL (2)
• C3D will avail crews (with relevant discipline /sub-discipline)
supplied by the subcontractor into the weekly planner/Lean board.
• C3D uses progress data to calculate payments to subcontractors,
using the rates in the sub-contract PO.
• C3D calculates payment due to subcontractor with relevant
deductions.
• C3D will link to all documents tagged with subcontract code to give
contract admin accessibility to all documents, drawing registers
and communication in Document Management System
