What Is QS Estimating?

QS estimating is the process of pricing building elements using drawings. This is done by a quantity surveyor (QS). Its most common use is in construction cost estimation.

This system is reliable and offers a time-efficient solution to other estimation methods like paperwork or Excel work. It also reduces human calculation errors.

Building Information Modeling (BIM)

BIM can help to improve collaboration and communication between architects, engineers, and contractors. Its advanced 3D visualization capabilities help stakeholders better understand project requirements, reducing misinterpretations and errors. It also helps reduce the costs of construction through accurate cost estimation and quantity takeoff. BIM can also be used to detect MEP, internal, and external clashes early in the design process, avoiding delays and rework.

Using a collaborative data environment (CDE), BIM provides a shared platform for the entire project team. It can be used in all phases of the building life cycle, including design, planning, construction, and operation. CDE solutions also support the processes of BIM and can be integrated into the management workflows of a company’s enterprise content management system.

The benefits of BIM extend beyond enhancing design and estimating to supporting the construction management, project management, facility operations, and green building processes. Its use in the design and planning phase can reduce rework, improve schedules, and distribute risk across the project team. It can also provide cost savings by providing an accurate digital model of the building that can be used for comparison with the actual physical structure.

Moreover, BIM can improve the coordination between designers, architects, and contractors during the estimation and bidding process. It can also eliminate the risk of rework and delay by ensuring that all the relevant engineering calculations, equipment documentation, and drawings are available to those involved in the construction and operation of the building.

Web-based QS frameworks

Web-based QS frameworks are a great way to automate the estimating process and reduce the number of errors. These systems allow users to easily view, input, and update the construction costs of a project, which can save time and money. They also allow for more flexibility and are easy to use. Moreover, these tools can be used for different purposes, including cost estimation and planning.

QS estimating is an important component of any construction project, and requires precision and efficiency to be successful. However, traditional methods of estimating can be time-consuming and difficult to implement. To solve these problems, a new wave of digital innovation has swept through the industry and transformed the role of QS Estimating Software.

The proposed web-based QS system provides a convenient interface for estimating construction projects and enables users to select the items for cost calculation. It also offers a variety of features, including block information, PCC calculation phases, ground floor steel and concrete calculations, and a complete breakdown of the cost estimate. It is also compatible with various file formats and can be exported as a CAD or Excel sheet, a word document, or an Acrobat Reader file (.pdf).

This research explores the effects of the proposed web-based QS estimating framework on a quantity surveyor’s time spent performing estimation activities. It is compared with standard paperwork and Excel work, and the results indicate that the proposed framework saves more time for the QSr than manual processes.

Open-source QS software

A web-based QS software is a reliable solution to help reduce human error and minimize time spent on preparing a cost estimate. It automates the processes of paperwork and Excel work and provides a secure environment for users to store their data. It also allows you to access your data from any device and provides features that can be customised to meet your needs, such as user-specific dashboards, bill calculators, Gantt Charts and more. A popular choice for SMBs is Orangescrum, which offers a free one-month trial for up to three projects.

When selecting a QS software, it’s important to consider the different pricing models. Some companies charge a single fee for the software download, while others offer standard subscription tiers that are billed monthly or annually. Some products are even a combination of both methods. In addition, you should pay attention to the level of customer support offered by each vendor.

Many estimating software tools allow you to create and store specific information about assembly or item details, such as the cost and quantity of nails and wood in a residential interior wall. These assemblies can be reused in future estimates, saving you time and money. In addition, some estimating software programs include an up-to-date database of supplier pricing for materials and supplies. For example, the RSMeans from Gordian provides an industry-standard database of local prices for materials, and ElectricSmarts NetPricer includes pricing for electrical supplies.


BIM-LEAN is an emerging technology that allows Quantity Surveyors to automate the measurement and takeoff of quantities from a model. It can also reduce errors with interface and collision checking, and improve accountability. It can also mitigate issues that might increase cost or risk and enable better life cycle assessment. This approach is a good alternative to traditional methods that rely on drawings and specifications.

In addition, BIM-LEAN can help QSs do a more accurate and timely cost appraisal for alternative designs. This helps them to make decisions early in the design stage. Using this technology, they can eliminate wasteful activities and improve productivity by focusing on the things that really matter to the project.

Several tools have been developed to assist in the integration of Lean construction with BIM during the design phase, including dRofus and Solibri. These applications can improve information flow in the planning and control zone by making it easier to coordinate design data with other team members.

This research is designed to examine the impact of BIM-LEAN on quantity surveying practices. It will evaluate the benefits and challenges of BIM-LEAN in the context of the changing role of quantity surveyors. It will also determine the current level of awareness of BIM-LEAN among quantity surveyors. This will help identify the potential of new roles in the third generation of quantity surveying services triggered by BIM-LEAN.
