4D Construction Sequencing

We offer 4D BIM Simulation or Construction Sequencing for your Building Information Models. The whole process during the construction phase is integrated with the fourth dimension of time.

We use the Autodesk Navisworks platform to create 4D Construction Simulation/Sequencing based on the planned construction process. With the generated sequence the construction planner can simulate the planned process, identifies any potential clashes, effective material planning & management, improved site utilization planning & coordinate with ongoing operations.

The baseline schedule obtained from Primavera or Microsoft Project is directly linked with Building Information Model to produce the 4D Scheduling/sequencing. The construction sequencing helps to schedule conflict between multiple trades during the construction phase, thereby reducing the time taken for the whole construction process.

BIM for Preconstruction Logistics Planning

At Drawlines, we utilize BIM for Preconstruction Logistics planning to develop the proposed site logistics in 3D & 4D. Our engineers work closely with our client’s team of planners and designers to create a 3D visual logistics plan that attributes to the project requirements.

The benefits of 4D BIM modeling

  • Risk mitigation due to improved team coordination and communication
  • Conflict detection
  • Improved delivery time and cost savings Improved quality

5D BIM Services

5D BIM refers to the integration of cost-related information along with time into the 3D BIM model. With 5D Cost Integration, we can calculate the overall cost incurred during each phase of construction. In the construction cycle, quantity and cost estimation can be considered one of the most difficult, time-consuming activities. The BIM process has brought a significant change by quickly extracting the quantities and costs from a 3D model.

Uses of 5D BIM

  • Conversion from BIM 4D to 5D for accurate cost estimation and quantity take-offs.
  • Extracting accurate cost estimation for the ongoing projects or bids.
  • Extracting BOMs, RFIs and construction documentation from BIM-ready 3D models to manage multidisciplinary works.
  • Highlighting the changes in BOQ of tender vs construction project.

Advantages of 5D BIM Services

  • The total cost can be estimated in the pre-construction stage
  • Design changes can be made according to the budget
  • Helps to find the potential spots in a building which add up the additional cost
  • Predicts how a change in design affects the cost and schedule of a project
  • Provides risk analysis for a project and accurate cash flow forecast preplan staff allocation

With the effective implementation of 5D BIM services, the Architects, Engineers and Contractors can work collaboratively to achieve quality, timely delivery and cost effectiveness for a project.

BIM for FM

Our services in BIM Facility Management consists of delivering information models that can be used directly for managing and maintaining the asset by FM teams and owners. Our BIM specialists develop data-rich BIM models of the building that facilitates the tracking and extraction of various asset-related data such as specifications, operation manuals, component status, warranty data etc. This helps in pulling out the specifications of a certain part and makes the replacement relatively quicker and easier.

Facility Management can be defined as the process of utilizing BIM models for managing a building`s maintainable assets. All the parameters that are associated with the components of a building are integrated into data-rich geometrical models. This data is utilized during the entire lifecycle of the asset.

We have delivered COBie facility management services for stadiums, rail, commercial, industrial, hospital and educational facilities. Customer satisfaction and project quality deliverables are the core of all our services and we constantly strive to add value to the projects by understanding our client’s requirements precisely and delivering up to the client’s satisfaction.

Advantages of BIM Facility Management
  • Using BIM in asset management helps to build managers and owners to speed up informed decision making process by making informed decisions regarding repair, maintenance, spatial requirements and energy evaluation.
  • Facility Management enables the tracking and extraction of asset data (such as specifications, status, operation manuals, warranty etc.) thereby streamlining and easing asset management and replacement during its entire lifecycle.
  • Facility Management simplifies activities such as routine maintenance, space management, energy efficiency, remodeling and renovation by providing useful data for the specific requirements thereby saving time.

BIM Shop Drawings

We support contractors in delivering accurate shop drawings from BIM Models, construction documents and the specifications prepared by architects or engineers. With our shop drawings preparation/extraction services, we create quality drawings that include details like dimensions, material information, manufacturing standards and fabrication details of components. At Drawlines, we use Autodesk Revit to develop BIM shop drawings from fully coordinated 3D models. The Drawlines engineering team has access to advanced tools, such as Autodesk BIM 360, Revit, and AutoCAD to provide specialized shop drawing extraction service to our clients.

BIM Coordination Services (Clash Detection & Resolution)

We provide clash-free 3D models by detecting and resolving clashes right in the pre-design phase. Our team of engineers, architects and MEP technicians works together to not just check for interferences but also channel their domain-specific knowledge to ensure that the clash is resolved at the earliest. We use advanced software like Autodesk Revit, Civil3D, Tekla, AutoCAD and Navis works to provide all discipline BIM Coordination Services.

Our BIM Coordination Services have enabled a smooth and quick completion of various mega projects (stadium, rail projects), commercial and industrial projects.

Our BIM Coordination Services include
  • MEP BIM Coordination Services: We perform BIM Coordination between Architectural, MEP and Structural disciplines as well as internally within the MEP discipline i.e. HAVC, Electrical, Plumbing, etc. We mark up any such clashes that need a design change and discuss this in collaboration with all the parties involved in construction. This helps everyone to be on the same page as far as design is concerned.
  • BIM Clash Detection: Clash detection and interference checking is the first step in the coordination process. BIM clash detection encompasses interference checking, extraction of clash reports and performing design validation to ensure there are no major collisions between Architectural, Structural and MEP disciplines.

COBie Services

COBie or Construction Operations Building information exchange is a standard, it’s a data format that helps capture and record important project data at the point of origin, including equipment lists, product data sheets, warranties, spare parts lists, and preventive maintenance schedules. This information is essential to support operations, maintenance and asset management once the building is in service.

Drawlines works on the information provided by the client on product data sheets, equipment lists, materials lists, etc. All this information is used for 3D Revit Modeling which can be used for operations, maintenance and asset management once the built asset is ready.

  • Setting up and structuring COBie database (Excel sheet or other).
  • Producing data drops at set stages of a project, through the design, construction and operation phases.
  • Setting up the models for COBie compliance.


Drawlines can facilitate the delivery of COBie Data Drops following the client’s requirement by providing a wide range of services to manage, validate and deliver COBie on your project.

Material & Quantity Takeoffs (BOQ)

Traditional Quantity Estimations were performed by Architects and Engineers from 2D CAD drawings. With the advancement of the Building Information Modeling process, the BIM-based quantity take-off has brought us more accurate and efficient quantity takeoff services within a quick turn-around time. The BIM-based QTO process also avoids potential inaccuracies and human errors and always makes sure that the extracted quantities are aligned with the design.

At Drawlines, we use Autodesk Revit, Autodesk Navisworks & MS Excel for preparing BIM-based QTO and estimates. Highly detailed, data-rich, intelligent 3D Models are developed using BIM authoring tools, and elements are linked to the corresponding materials to perform the automated QTO process.

  • Cost analysis
  • BOQ & BOM preparation
  • Review of estimates
  • Cutting list preparation

3rd Party BIM Auditing Services/BIM Model Review

Drawlines Consult offers BIM auditing services to contractors, construction and fabrication companies. It is a usual practice among concerned companies to validate an objective of specific BIM models. Our BIM auditing services will make them sure of the accuracy and consistency of information presented in BIM (building information modeling) in line with the LOD standards.

The BIM Audit Checklist

Following are the few main things that we consider in our BIM audit checklist:

  • Compliance with BIM execution protocol
  • Compliance with different processes and standards
  • Inspect a regular model review and the model checking procedure
  • Federated model being used for 3D coordination and clash detection in BIM
  • Model accuracy verification against the design intent
  • Federated model being used for sequencing, programming, and planning
  • Models are effectively used for the performance analysis
  • Structural analysis
  • Energy analysis
  • Life cycle cost analysis
  • Operational asset information models for facilities management


The whole process usually demands certain standards checks that include evaluation of folder structure, conventions, drawing, and sheet naming with integral checks like design validation and verification along with the implementation of building code. We also ascertain the different outputs like the bill of quantity (BOQ) Construction Documentation sets, and shop drawings through a reliable BIM model and stick to the industry’s best standards, practices and development levels (LOD).

Audit of the Federated Model

  • We audit the model used for coordination and clash detection in BIM (3D BIM)
  • We audit the model useful for construction simulation and sequencing (4D BIM)
  • We audit the model that is useful for quantity take-off and demand-supply management (5D BIM)
  • We perform an analysis of the BIM model (6D BIM)
  • Our operational asset information models are for facilities management (7D BIM)
