Fire BIMBIM-based project management with fire protection content
BIM-based projectmanagement with fire safety content
By Fire BIM, we mean the extension of the BIM-based project management and background database enrichment with fire safety data at different levels of detail in the design and construction phases of construction projects, including fire safety requirements, fire protection compliance, performance declarations, permits, built-in fire protection product characteristics, which can be displayed in the design phases and, which can be easily accessed in the BIM space later during operation and maintenance, depending on the position in the facility. The necessary fire protection definitions, 3D visualisation and knowledge base are provided by our company in cooperation with the BIM management of the project.
There are many areas where efficiency can be significantly increased during the preparation of construction projects by using Building Information Modeling (BIM) and project management methods, which puts the building project’s design related information to a higher level. BIM is a set of CAD-based design principles, methodological processes and guidelines that enables the participants (builders, designers, contractors, operators) interested in the construction and operation of buildings to cooperate between each other, transfer information and effectively display relevant data quickly in real time. Today underneath the letter "M", the word "Management" is often understood also. BIM management is not a sub-process of engineering design, or construction, nor is it just a three-dimensional model (see below), but an engineering support that is organically related to investment project management, the goal of which is to organize the construction and implementation phases effectively without having to recur additional change orders. The application of BIM methods results in high return on the investment cost if it is used properly by trained professionals, appropriate software support and IT infrastructure environment.
The involvement of BIM methods into building investment projects is an excellent solution to reduce the risks of an investment, while maximizing possibilities on the ongoing design process and, at the same time, minimizing unexpected investment related cost. It’s safe to claim that the future is unimaginable without the BIM, so our company is trying to fill in the lack of current BIM expertise in the domestic market and aims to provide the related professional services internationally also.
APPLIED BIM MODELS and DIMENSIONS
2D (CAD): Placement and display of structural elements in virtual space including geometrical information only. The model can be created in 2D and 3D views.
3D (BIM): a visual, geometric and parametric model of related building elements built in 3D virtual space in which the information content establishes the amount of building material applied.
4D (BIM): 3D model’s information content is complemented by the construction time and schedule of a given building element. By the use of 4D BIM models the construction process can be displayed as an animation.
5D (BIM): includes the implementation cost in addition to the amount of materials indicated in the 3D BIM model and the normative work schedule data (4D BIM) related to the architectural elements By the use of 5D BIM mdel cost estimates, CAPEX budget and financial schedule can be prepared.
6D (BIM): this model is an information supplementation to the geometric 3D BIM with building related energy and building physics data that lead to the optimization of the energy usage, sustainability of the building, and to the creation of life cycle analysis and related calculations. 6D (BIM) model’s information content may include the manufacturing and installation data of each building material and structural element, their prescribed maintenance frequency, lifespan, and rules for the optimal building operation.
7D (BIM): this model is a supplementation to the virtual building elements information within the geometric 3D BIM model with descriptions (user descriptions, specifications, guarantees, etc.) to support facility management processes and small service systems during building operation.
BIM BASED SERVICES
The BIM related services we offer are related to several applications of the building information management concept and tools including in the first place the establishment of transparent working processes based on continuous interdisciplinary exchange with engineering information and applicable solutions. Our introductory material is not intended to be inclusive on all BIM aspects, here we simply illustrate that BIM is a new vision and a revolutionary toolkit for the effective investment management facilitating technical and economic needs of any building construction and operation projects. BIM workflow management is based on the Client’s clarification of requirements and necessary conditions which are included in the contracts and in the most important document of BIM management: the BEP (BIM Execution Plan) serving as a baseline during later stages of the project. Field works have to be carried out such as geodetic surveying, geo-scanning, soil mechanics surveying, point cloud surveying, and , finally, a 3D model must be created containing every surveyed object on the site with their known specifications. The design phase starts with a reciprocative exchange based on regular data submission by the participants supported by systematic documentation and clash detection in order to minimize errors in the design. Quantity take-offs and schedules derived from the BIM model will help to finalize and adhere to the construction schedule.
In each stage of the construction the actual BIM model is being compared to freshly created point cloud surveys and every discrepancy, or non-compliance is documented and forwarded toward the Client.
PROJECT PHASES SUPPORTED by BIM
a) Planning and Design
b) Tender – Project preparation
c) Construction, implementation
Typical project difficulties manageable by BIM methods:
⮚ Incomplete, or incorrect technical design
⮚ Use of materials - improper material application determination, material determination “Not Available in Trade”
⮚ Dimensions - improper, or missing scaling Téves mennyiségi kigyűjtések (BoQ)
⮚ Improper determination of work phases
⮚ Design and plan anomalies, improper elements of the design documentation: blueprints, design seals, dates, static, technical descriptions, budget statement
⮚ Clash detection - interdisciplinary merging of the design (see more further)
⮚ Adherence to cost and reserve budget frames - accurate design producing quality tender documentation
⮚ Evaluation of change orders, value and scopes
⮚ Optimization of material and service procurement
⮚ Recording and updating “as-built” documentation
ADDITIONAL SERVICES USING BIM APPLICATION provided by us
CRUSH ANALYSIS - CLASH DETECTION
The aim is to systematize interdisciplinary collisions. The detection test is a process based on constant ffeedback, whereby different engineering designs are virtually merged during planning, which systematically identifies and lists in one place all clashing overlaps and model elements. There are chances that each new design amendment leads to the occurrence of new mistakes, so the design process is the most effective if the maximum information is available for the engineers at the time of the design modification. In addition to the clash detection all model files received in .ifc format and all performed clash detections are accurately documented, so the processes can be well followed upon.
BILL of QUANTITY, BUDGET PREPARATION and SCHEDULE
Detailed object classification and properly specified material properties determine the exact need for building materials in each building. The material selection can be based on area unit, unit of volume, or on the number of pieces to be determined by the type of the given structure. Costs are to be determined at any phase of the project by creating and assigning cost classes and resources classifications. In accordance with the construction process, the sequence of the model classes and the time needed for the work phases can be specified in due course, so a responsive schedule can be prepared in a short period of time. These statements are integral parts of the BIM management process, and our team can provide them if needed.
GEODETIC SURVEYING
⮚ Geodetic survey model and survey protocol
A professional surveyor team carries out field survey tasks, creates field drawings and local mesh markings used later during the construction to prepare the necessary data for planning. The data recorded during the surveys and the 3D BIM model based on these data contain huge amounts of information in virtual space, ready to be used by the design engineers immediately. The survey model can be made in the preferred software so further designing activity can be continued smoothly. Each object present in the model can be scaled and modeled for further design. Based on the 3D model the traditional blueprints, the necessary views and sections can be completed with additional elements, as requested. No additional, intermediate steps are required, instead, a model will be in place containing all relevant data, which can be handled without the need for conversion when using any major software for design. Our services are in line with international BIM standards.
⮚ Laser scanning
Lase scanners are the most efficient instrument to explore and measure field objects, buildings, or just to measure vegetation and the surface characteristics. LIDAR based laser scanning stations significantly reduce the survey time even for the largest facilities compared to the traditional manual measuring methods. The measurement is very accurate down to a tolerance of 1 mm, so unusual geometries and smaller details can be surveyed correctly. The extracted point cloud is to be easily adjusted to the geodetic base mesh in order to be used as a correct EOV reference with a real absolute position in space. Soon after the survey a full colored and correctly arranged spatial point cloud is in place to inspect, to measure, or even to conduct virtual site-tours. With the help of 360° panoramic pictures taken at every measurement point an extensive immersion can be achieved. The extracted and processed point cloud serves for the preparation of a parametric 3D model with dimensions which are the starting point for the design and measurements. We create the desired models matching the CAD software preferred by the Client.
⮚ Geoscanning
The goal is to map up and discover underground objects before starting the groundworks as fast as possible. It is a very effective method to search for utilities, tunnels and other long-forgotten structures in large areas. A survey based on the reflection interference of electromagnetic waves provides for the detection of underground objects in the construction areas resulting in a complex data set that is to be visualized in 3D and incorporated into the BIM model. The end result is a 3D model with every detected underground object in it directly implemented within the BIM model, which can be used anytime during the project. Based on the professional experience and high-tech instruments of our specialists even the most complex construction areas can be screened in 1 week.
IT APPLICATIONS
⮚ Bexel Manager
We preferably use Bexel Manager software as it is one of the most robust, database operated BIM management software for handling BIM models. Bexel Manager enables simultaneous handling of several large models within the same project, the number of which is limited only by the hardware resources and the size of integrated models. Using Bexel Manager even the most extensive projects can be quickly and easily accessed, while a complete toolset palette is available for BIM model based design review and model management.
⮚ Virtual reality
Using professional visualization tools the building and its surroundings can be inspected in order to assess how they will look according to the current state of the design in the frame of a virtual site-tour. Virtual reality can be taken even out to the field by the use of special glasses, or tablets so that the physically present and virtually created objects in the new design can be seen in overlap, real-time. Based on such virtual experience engineers can alter the objects or virtually move walls during the actual design phase and see local problems, clashes otherwise hidden from the designer’s desk. Virtual reality check can be done as photorealistic virtual flights, or highly realistic sneak-peeks into the future of your project leaving nothing to one’s imagination.
