BIM can improve quantity surveying process greatly

BIM & Quantity Surveying

BIM (Building Information Modeling) is now liable for executing many traditional QS functions automatically with its 4D modeling capabilities.

A Building Information Modeling (BIM) system can computerize the measurement of quantities from construction drawings. This will facilitate contractors to have design documents which include exact quantities and specified materials in electronic format.

With the utilization of a correctly configured Building Information Model, an exact bill of quantities (BOQ) can be generated automatically. The BOQ is then applied to create reports in the essential format. This is performed with any phase of the QS dispatch ranging from estimating, tendering and construction control.

By utilizing BIM the contractors will be able to keep a visual record of what has been measured where. This will help contractors to detect clashes and co-ordination errors.

The importance of BIM from a measurement and costing viewpoint :-

i) It will form the geometry of what has been or might be designed.

ii) Identify the work scope in Bills of Quantities and colonize the Bills with quantities from the model

iii) Specification, auto-annotating the 3D and 2D drawings from the model including dynamically linking the Bill descriptions to the specification.

BIM allows the entire design team to perform on the same plans eliminating the requirements to digitize drawings. In a BIM process entire supply chain is involved and the material manufacturer will get the ability to contribute their own costs. The huge time saving is possible on the cost planning phases. Besides BIM also provide better cost models to fulfill the demand for VFM (value for money) all through the sustainable building development.

How project stakeholders can apply BIM in their work process

BIM can be applied as a work process and means of communicating with one another in the project delivery method to illustrate the end product (the model itself).

BIM generated a virtual process that covers all characteristics, disciplines, and systems of a building inside a single, virtual model facilitating all project stakeholders to work together more precisely and competently. Thus BIM creates a collaborative design process.

After the creation of the model, team members are continuously clarifying and regulating their portions in accordance with owner preferences, system's adaptability and design intention to maintain the accuracy of the model before the commencement of the actual project. If any modification is made by the project team members, it affects the entire model, creating continuous communication

After that the model itself is utilized to exchange information for design concepts to the owner. The model is also applied for estimating materials take-off for cost estimation and for conflict detection to electronically verify the proper designing of the building system. BIM can trim downs change orders by making changes electronically rather than on the job site which can get a huge saving in time and money for project schedule and budget.

Design information from all disciplines as for example from architectural designs and specifications to structural and mechanical systems information such as HVAC Ducting, piping and structural slabs, columns and shear walls are provided in the BIM database. The database includes and combines all elements of a finished building to one main database of linked project information. If any, the BIM database would mechanically rearrange all connected elements implanted in the interrelated database to communicate with any changes occurred with one element of the design.  A BIM database can surpass it’s 3D modeling capability and perform for 4-D (construction scheduling) and even 5-D (cost flow analysis). The database could significantly lessen waste in construction as well as time delays raised  by RFIs and change orders. 

BIM has also shifted time spent in various phases of design, placing more emphasis in the initial design phases and less in the construction documentation phase. Whereas with traditional CAD processes the bulk of the time was spent preparing construction documents, BIM requires more time up front, fully develop the design and model. When a BIM project goes into construction documentation, all that’s left to do is decide where to cut sections through the building and print the documents.

BIM can flawlessly gather in and incorporate the input and flow of information among design and construction professionals to make the entire process more efficient and reduce delays and cost overruns.

BIM can characterize a design as objects in the form of indistinct and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), which contains their geometry, relations and attributes. The geometry possibly will be 2D or 3D. The objects may be conceptual and are constructed detailed. A building model is described by compiling together these objects. If an object is modified or moved, BIM tool then starts to dig out diverse views from a building model for drawing production and other application. These diverse views are mechanically constant i.e. the objects are all of a constant size, location, specification. Drawing uniformity reduces many inaccuracies as each object instance is defined only once.

Modern BIM technology identifies objects parametrically. Here the objects are identified as parameters and relations to other objects, in order that if a correlated object is modified, this one will also. Parametric objects mechanically reconstruct themselves in relation to the rules implanted in them. The rules are uncomplicated, involving a window to be wholly within a wall, and moving the window to the wall, or complex defining size ranges, and detailing, such as the physical connection between a steel beam and column.

BIM can enhance project visibility by providing 4D scheduling

The accurate construction schedule can efficiently communicate the project plan among team members for the successful completion of the project.

Now-a-days BIM is an inheritant part of construction scheduling. BIM can be integrated with construction scheduling to facilitate 4D scheduling. Thus BIM assists to communicate the project plan visually in respect of the timeline to the project team prior to the commencement of actual construction.

A large project involves many stakeholders. So it is very important to schedule the whole project in order to bring out the amount of material, number of labors and possible expenditure. BIM Outsourcing helps them in the project management by providing the BIM model with lots of usable information. A proper sequence helps them to track and analyze any problem and detect conflict and mitigation.

BIM can be utilized to provide 4D (scheduling integration) and 5D (cost/productivity and resource loaded estimating) capabilities for the completion of project cycle and generating synergy among existing systems.



By connecting the CPM construction schedule to the BIM, the 4th dimension of time is added to the model. This leads to a virtual construction simulation facilitating a graphically wealthy and animated representation of the planned construction sequence set against time. The project controls capabilities are also developed. The project managers get the ability to focus their resources by highlighting the critical path activities inside the model.

4D schedules are a influential tool for design and engineering documentation and analysis, phasing, more accurate cost estimating, optimized means and sequence of work, invoice reconciliation with work complete on-site, on-site production control with the Superintendent and the Subs, design intent and construction plan, an information rich as-built model for facilities management, well organized trade coordination and communicating planned work to the different kind of audiences as well as project stakeholders and those directly liable for project execution.

With the help of 5D construction scheduling, precise bills of quantity are generated, which can be utilized for amalgamating cost and schedule. This leads to incorporate estimators, cost managers, and planners into the scheduling process.


Advantages of BIM for construction scheduling :-

• Lessen and or eliminate costly delays which can affect your construction schedule.
• Facilitates communication with your subcontractors more competently and successfully
• Organize procurement orders to make the delivery of key materials in time
• Assists for executing the construction activities in time
• Enhance the responsibility between the project owner, general and subcontractors
• Enhance project visibility, increased profits, reduced costs, faster cash flow and earned value reporting

BIM and benefits of owner

The owner should embrace BIM to reap the benefit of a well-organized and extremely coordinated method of project delivery. Project schedules are also curtailed and overall project costs is decreased.

A BIM model contains huge database of vital information and the owner can utilize these information for analysis and decision making. The database is repetitively updated and filtered during the life cycle of the model. Besides modification can be made at a single location in spite of how many times the data is presented or distributed. The recurrence of requesting, parsing, assembling and transmitting information among team members at the different arenas of a model’s life is significantly decreased or removed. This leads to improved communication between team members and more apt reply to owner concerns or suggestions.

BIM generates coordinated construction documents which can enhance the efficiency of the design and construction procedure. The owner can gain huge cost saving as the project scheduled is accelerated to a great extent.

The owner can apply BIM at pre-design phase and expand it during the design, bidding, construction, occupancy and finally decommissioning of the building.

BIM plays a key role in allocating data for analysis and simulation. BIM makes it possible to develop the amount and types of project analysis. This may vary from early investigation of building energy efficiency throughout conceptual massing, to structural/mechanical/electrical load analysis all through design, quantity take-offs throughout the project bidding, shop drawing review/fabrication all through construction, or even facility asset management throughout occupancy. The owner obtains more value by allocating different analyses to be executed with the transmission of data. This is applicable where numerous iterations of an analysis are replicated and purified at different phases of the BIM lifecycle.

Some exclusive benefits of owner:
• Owner gets the advantage of informed decision-making with the high-tech analysis of building systems, alternative materials, equipment, and technologies
• The owners get an idea about the estimation of the materials and the sequence of work.
• BIM delivers the best 'what if' situation and facilitates the owner to pick up the best one.
• Solve the constructability issues.
• Trim down contractor doubt facilitating a more precise cost representation and more reliable bids.
• Assist project team to build up a realistic and unified phasing plan.
• Minimize general project delivery time throughout the design stage in addition to the construction phase.
• Enhance overall accuracy of project documentation.
• Facilitate the analysis of sustainable design alternatives and cost comparisons.
• Generate perfect and well-timed information instantly available to team members at several locations, with the construction site.
• Makes the way to get better asset management.
• Presents a mechanism for improved building and equipment maintenance.

BIM provides a great benefits to Structural Engineering Firms

Now-a-days structural engineering firms are extensively adopting BIM platform with Revit Structure, Tekla Structures, and Bentley Structural to dramatically improve the processes of design and analysis. Theoretically, the architect generates the model with the application of BIM software, bypasses it on to structural engineer who runs it in an “external analytical engine.” The model is “brought up to dated” back in BIM, which is then employed for completion of the project.

BIM can be utilized for structural analysis design and detailing, structural drafting on all major structural engineering projects ranging from reinforced and pre-stressed concrete, steel and composite structures etc.

BIM facilitates a wide array of structural engineering & modeling services like structural steel detailing, shop and fabrication drawings, construction drawings, erection layout, anchor bolt layout, stairs and handrail, grating and platform, foundation layout, rebar detailing, post tension slab detailing, wooden structure detailing, prefabricated structure detailing, water retaining structure detailing, bridge detailing, structure design and analysis, structural drafting, RC design and detailing.

BIM benefits for structural engineering

BIM can make an evolution in structural building types with scheduling and fabrication. Curtain wall, steel and precast concrete can be fabricated and assembled offsite in shops from the BIM with computer controlled equipment.

The contractor can utilize BIM to harmonize the components for "just-in-time" delivery and installation exclusive of significant site storage and handling.

Structural engineers can apply BIM to get the detailer’s model along with the paper shop drawings to apply as a tool in organizing and recording their comments. This in turn diminish the engineer’s time and attempt in evaluating shop drawings and decrease the overall fabrication process for owners by allocating fabricators to receive the engineer’s comments in digital models.

Centrally manages the geometry information in the individual models to aids interference detection and change control.

BIM can be applied to improve multidiscipline coordination of structural design documentation, minimize errors, and enhance collaboration between engineering and architecture teams.

BIM can speedily model several structural variations and work with the design team to choose the best. Early BIM prototyping can also lower subcontractor costs.

BIM can improve schedules due to better coordination between trades. Clash detection and coordination can reduce non-discretionary change orders that would otherwise come up.
