Building information modelling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places. Building information models (BIMs) are files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a building or other built asset.
In this presentation, a quick but comprehensive introduction to Building Information Modeling (BIM) is provided, aiming at showing the benefits of BIM for all the actors of a construction project.

Integrating BIM and LEAN for Project Delivery - Construction of a Major Hospi...CCT International
Webinar presented by Mr. Zuhair Haddad, CCT's Chairman for the Lean Construction Institute on 1 September 2016.
Hospitals are ecosystems of diverse functions: laboratories, imaging units, ERs, surgery and operating rooms, inpatient quarters, etc. This makes building them one of the most complex tasks, specifically room completion systems as each set of rooms have their own furnishing and finishing requirements. This entails the existence of several number of trades, where coordination grows exponentially in importance. King Hussein Cancer Center in Jordan is a prime example with fast track requirements (3 years delivery) which increase the complexity further.
Join in this webinar Consolidated Contractors Company (CCC), a leading global construction contractor who will share the above case study where BIM, advanced work packaging and Lean were implemented in an integrated approach to manage the finishing activities for the hospital. The presenter will share some of key drivers for the success of this implementation:
• BIM authoring requirements to suit project controls
• Leveraging BIM to manage schedule, cost, sub-contractors, and material delivery.
• Installation Work Packages (IWPs) creation
• IWPs management using Lean approach
• Collaboration using BIM to support Lean processes
• Lessons learned.

32. 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)

40. Estimate Work Flow
• BIM assigns BOQs to the objects (BOQs should represent the method of execution)
• BOQs are aligned with the standard Workgroups
• Each Work group is comprised of one or more operations (usually work of one crew)
• Each Operation is comprised of a set of resources (labor, material, construction equipment and
s/c)
• Each operation may use controlling quantity of the BOQ or produce a proportional quantity
from past experiences
• By pricing all resources, the direct cost estimate will be produced and by applying in-directs,
contingency and profit, the total estimate price will be ready for submittal. The labor resources,
total man-hours per operation gives us the man-hours used in progress measurement and
earned man-hour calculations at later stages.
41. Budget Work Flow
Reorganizing the Estimate data by Responsibility (OBS)
• Invert the estimate hierarchy into Resources Operations Work groups
• Resource Level
• All material and s/c resources are moved to material/ subcontract costcodes.
• Material are sent to the procurement system that consolidates them into request for proposals
based on material families, PO’s are issued, and expediting information/delivery notes is sent back
• Operation Level
• Factory production operations and resources are moved to factory production costcodes
• Work group/ BOQ Level
• Work groups are moved by Area (BIM Take-Off by WBS)
• Updates to quantities from new BIM models are entered into forecast quantity column or until
the budget approval cycle is complete and then they will be moved to budget quantities
42. • Object to activity assignment
• A series of objects are organized together and then they are assigned to corresponding activity
based on a series of similar properties (category, WBS code, etc.)
• Once object is linked to activity and object is already linked to the resources, the following can
be deduced:
Planning Stage
When and how much of each resource is needed. Lag to be provided by project controls.
Number of crews needed by OBS and their corresponding S-Curve
Required Capacity of factory production
Construction equipment needed especially the heavy lift, etc.
Material needed by period

47. LINKING TO DOCUMENT MANAGMENT
• All Engineered documents (Drawings
& Specs) register is tagged with WBS
Code and Discipline Code.
• C3D will assist user to link
documents to work fronts (Objects &
Operations) based on common WBS
Code and/or Discipline Code.

54. Typical Rooms
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
55. 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
56. 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.
62. C3D PROGRESS COLORIZATION BY SYSTEM
C3D colorization method can visualize the actual progress percentage on each system.
63. 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
64. 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)
65. 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.
66. 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
