It is used for geometry and gives a better visualization of the project.
3D – This is about object-based modelling.
This is the original idea of computers accepting inputs and processing them to produce useful outputs. A BIM dimension is the ability of a specific BIM product to process attributed data to achieve useful information. BIM and Quantity Surveying in Kenya: Where’s the Disconnect?īIM use is looked at in terms of dimensions. In places where BIM has been adopted for such activities, the users have reported huge time saving as they were able to extract quantities from the model and use them for the preparation of cost estimates. The measurement duties which involve quantity take off, abstracting and billing are a time-consuming exercise that takes more than 50% of the QS time spent on a given construction project. The main role of the quantity surveyors in construction projects includes estimation and cost planning, procurement advice, measurement, preparation of bills of quantities and tender documentation, construction cost control, preparation of valuations, payments, contractual claims and final accounts. Quantity surveying is a client-led profession with the overall role of the quantity surveyors being a response to the needs and requirements of the client. While this definition is limited in some way, the quantity surveyors do calculate the cost of construction projects. The 10 th edition of the Concise Oxford Dictionary defines a quantity surveyor as a person who calculates the amount and cost of materials needed for building work. Non-graphical data such as cost plans, schedules, specifications, manufacturer information, material characteristics and performance data, among others, is then linked to the model to form an information model. This way of working relies on the creation of intelligent 3D models rich in a facility’s geometry data. The CDE is an online repository for project-related construction information that is accessible to all users, anytime anywhere. It is a collaborative way of working that involves Architecture, Engineering and Construction professionals thinking and taking care of the information needs of fellow project participants as they produce and share construction information.Īlso, it can be described as a data-driven process that allows all project participants to collaborate in a shared online workspace known as a common data environment (CDE). What is BIM?īIM is an acronym for Building Information Modelling, sometimes referred to as Building Information Management. This cannot continue if we want the Kenyan QS to remain valuable and competitive in the global construction market. Their fellows in the architecture and design professions are progressing way ahead of them and already reaping the benefits of BIM in their practice. Quantity Surveyors in Kenya have been left out of BIM according to research.
