Benefits of BIM for Surveyors throughout retrofitting of a construction works

The prime responsibility of a surveyor is to deal with several measurements, values, costs, schedules dimensions and demarcations which are gathered from trustworthy and precise sources of data. BIM facilitates the surveyors to avail and evaluate all this data in form of geometries, numerals, and essential foot notes [with annotations to building object and modeled elements] for clear-cut information.

As-built BIM models allow in visualizing the data, finally authorizing surveyors to obtain detail information as well as insights. This insight allows survey professionals to perform proper analysis with the purpose of giving suggestions to architects and contractors for the sake of occupants and all the stakeholders who are associated with the building design and development projects.

When it is required to arrange the BIM models in as-built conditions of the building, the construction works or the infrastructure are analyzed prior to scanning and redesigning the project.

By maintaining exact level of detailing of designs in BIM, the project is expanded and a development stage is reflected for construction management related decisions. Issues associated with constructability, probable clashes, challenges in building up a wall or taking off one, time and cost, etc. are examined, risks are computed and mistakes are amended in the initial phase by a team collaboration among the engineers and the surveyors.

Opportunities for Surveyors:

• BIM for surveyors enhances collaboration and co-ordinations between multi-disciplinary teams
• BIM facilitates the surveyors to work out embodied CO2 in buildings and recommend remedies
• BIM allows the surveyor to quickly finish the work cost-effectively.
• Produce accessible synchronized information concerning project performance & constant maintenance of the property
• Surveyors can make best use of their work profile with BIM
• Ability to make proper decision for spatial planning, material orders, and QTOs – in case of retrofitting

With BIM, the surveyors get the ability to accomplish their jobs efficiently & with superior collaborative input. BIM for surveyors is rightly crucial whether it is a project of new construction works or retrofitting a really elderly one.

Benefits of integrating BIM Level 2 with the project

The design is considered as the most vital phase of any project and the design should be proper prior to go ahead is the basis for smooth delivery and successful completion. Throughout initial planning phases, manufacturers and specialists can provide a wide array of benefits.

With collaboration, main contractors and architects can establish technical and estimating support as well as get benefitted from manufacturers’ consultancy and increasing knowledge of products and methods currently available that would fulfill the requirements of main contractor’s like offsite solutions or alternative materials.

Involving all related parties at design phase develops a collaborative approach from the beginning. Dealing with all the options obtainable to them, and getting manufacturers to participate in initial technical meetings, signifies the plan of the project on the whole is more up to date. Devoid of proper feedback at the conceptual and developmental design phases, the design during the project will always encounter modifications which possibly lead to both delays and extra costs.

Integrating BIM Level 2: Here, lies the importance of Building Information Modelling (BIM) Level 2 . The concept of BIM refers to the method of designing, constructing or managing a building, infrastructure or landscape asset with electronic information. Practically, it signifies that a project should be designed and constructed with data sets and images digitally, prior to visit the site. The purpose of BIM is to meet time, cost and quality needs by handling the project with a more organized and consistent method of work.

Collaborating from the starting of the project, all parties function collectively with the equivalent methods to develop a comprehensive and all-inclusive design that defines all required materials and methods employed as well as provides a final cost and timescale to hand over the project.

The successful completion of a project mainly depends on the Employer’s Information Requirements (EIR) and the BIM Execution Plan (BEP).

With the EIR settled throughout the vital design phases, it describes the project along with the implemented standards, necessary outputs, when these will be delivered and in what format, as well as any supporting documentation. All the parties associated with the project can get a clear conception of what is desired and to turn into BIM Level 2 certified, a customized BIM Implementation Plan (BIP) should be made.

Inside BIM, the BIM Execution Plan (BEP) belongs to a vital document as it sustains project integration. A written plan that gets all of the tasks and relevant information collectively as specified in the EIR, with all the stakeholders and processes taken into account.

Article Source:

By analyzing in the design phases, this BIM documentation is produced and can support the rest of the project during the construction phases right through to building handover.

With the implementation of BIM Level 2, allotting time in design and planning, and consulting with all related parties to receive their valuable specialist perception, the main contractor gets the ability to create an informed, fixed and detailed design to be utilized during the project as well as facilitates to guarantee timely, on-budget delivery and successful execution of the project.

BIM for Renovation of Historical Sites

BIM is shading off the conventional drawing rapidly. Building Information Modeling (BIM) introduces a new way for designing, constructing and operating buildings and infrastructure. The application stretches far beyond the known territory and it also touches the history with its best features and applications. For understanding the building designs and materials of historical sites, BIM brings out an unparalleled approach. Renovating buildings centuries old requires a comprehensive knowledge of structural designs.

The most known problem associated with renovating historical sites is identifying the structural design. BIM comes as a boon for the organizations that are conducting such works. They revealed that scanning the old construction is like lifting the pages of history and bring out the architectural theories decades ago. BIM has been used for surveying sites accurately that carve out the foundation step of planning the renovation work as per the structure needs.

Mapping historical sites let you understand how the materials have been used and transformed over times. BIM has been used in renovating the Attucks school in Kansas City. The red building was built in 1905 by Charles A. Smith. The building stands in the test of time as a historical site of the colonial revival influences and it has a great influence in the education history of the African-American community.

Nearly two decades after, Charles A. Smith was approached to extend the historical building with a two-story wing to eliminate the over-crowding issue. The task was challenging since Smith needed to match the aesthetic essence of the building while designing the extending part. He used original architectural detail to recreate the same value created decades back. Getting the complete details of the building was not easy and it needed a thorough survey.

Redeveloping Attucks in a new way was a complex task for the team and it required to unveil the existing structural design in the infrastructure. BHC RHODES, a civil engineering firm, shouldered the responsibility of offering 3D Revit Building Information Model. The company used the lider 3D mobile mapping of GeoSLAM conduct the survey work magnificently.

The survey brought out some necessary factors that were essential for carrying out the renovation work safely. The team revealed information about the deteriorating conditions of the wooden flooring, a possibility of ceiling collapses and poor air quality.

The revealed information helped the workers on site plan their job in a secure way. The firm took help from GeoSLAM ZEB-REVO for mapping the inside of the building. The lightweight, a mobile device used the 3D Simultaneous Localization and Mapping (SLAM) technology to perform the required job efficiently. The process is considered to be comparatively cost effective one to terrestrial, static or trolley based systems.

ZEB-REVO is incredibly designed for mobile mapping and surveying for multi-storied buildings. The device allows you to scan the inside of a construction just while walking around. For the Attucks School, the data received by this device generated 200BIM models.

The application of BIM in layering the historical sites proves to be a new approach. It opens up an array of benefits that lead to a flawless working ability. Sometimes the owner of building needs details about how the renovation work will be done and which material will be the best for work. BIM presents a design that contains every detail required for getting a quick approval on the proposed plan.
