Critical Plan Strategies: General Contractor-

Role in following BIM use: • Cost Estimation- Providing market price data for construction materials

and labor cost.• Building System Analysis- Following sustainable design codes and

checking on referred electrical consumption data.• 4D- Modelling- Planning and time scheduling.• Engineering Analysis- Checking on codes in BIM Tool at each

construction phase.

BIM Project Execution Plan

Engineer-

Role in following BIM Use:• Design Authoring: Authoring of Structural Model using Autodesk Revit

software• Coordination: Rectification of conflicts in different models detected through

BIM Tool• Cost Estimation: If estimated cost exceeds set budget constraints then

reviewing the model and making necessary design changes if possible without compromising quality.

• 4D Modelling: Assisting General Contractor in Collision Detection through Navisworks Model and also rectifying the conflict areas accordingly.

• Building System Analysis: Checking and analysis of each construction phase and also operational phase of warehouse in terms of sustainability and efficient energy requirements.

BIM Project Execution Plan

Architect:

Role in following BIM Use:• Site Layout & Planning:1. Layout Planning & measurements - 2D drawings - reference for design teams.2. Overview of project requirements and getting started for architectural as well as

structural models.

• Design Authoring:Architectural model is a scale model which is used for show & presentation for referring 3D view of warehouse. Autodesk Revit was used to finalize this model.

• Coordination:After coordination checks, if architectural conflicts are detected then architect is responsible to remove the conflict areas in concern with the client as architectural model firstly refers to client requirements.

Reference Model: Cold Storage Warehouse - Angola

Architectural Model: Autodesk Revit

HVAC Engineer:

Role in following BIM Use:

• Coordination:HVAC Model will also be analyzed in the coordination stage to check for any conflicts between different models and phase. So, it is necessary for HVAC Engineer to participate in the check process and rectify the conflicts in concern with different departments and models.

• Cost Estimation:If the estimated cost exceeds budget constraint then HVAC Engineer will be assisting Engineer in his model where models will be reviewed for better solutions to get under budget constraint without compromising quality.

DATA GAPS:

Addressing Information Gaps:• In "Site Modeling & Planning”, the finalized drawings should have been from

3D AutoCAD to give the design teams an exact approach in their modeling process.

• In "3D Designing" phase, the design teams of different trades should have coordination in the early stages of modeling which will reduce rectification capital, time and as well as energy consumption.

• Pre requisite draft which clarifies the scope of each trade separately and at the end concentrating on the scope of project. All the design teams should have thorough knowledge about each other's scope so as to reduce rework and rectification cost.

Lessons Learnt:• Early realization of “Data Gap” and finding ways to address those gaps.• There should be a pre-requisite data for every BIM use, collaboration and

planning which will make the coordination more efficient.• Departmental and phase oriented scope should go hand in hand with scope

of the whole project.• BIM Models have better user interface, geometric representation with

detailed and precise design measurements similar to real world.• Models in a BIM Tool can be networked easily for supporting time

dependent decision making.• Energy performance analysis can be very well executed in a BIM Tool

where it can reduce simulation errors during modelling and building operations.
