BIM Model Development
In case you have project design already created using traditional 2D approach that is not the reason to lose all the benefits of project BIM implementation.
We have vast experience in developing highly complex BIM models with different level of development (LOD200, LOD300, LOD350, LOD400), and have developed BIM models of different LOD for over 12 million square meters of total project area.
Our team of BIM engineers is able to rapidly upgrade your 2D documentation to detailed and information-rich 3D BIM model that will serve as solid basis for carrying out BIM simulation & analyses related to constructability issues, extracting resource quantities, cost & scheduling (4D/5D) and project management tasks.
During development of BIM model based on 2D design documentation, we analyze it in terms of completeness and identify deficiencies and inconsistencies significantly improving quality of design documentation;
Design Review
We provide service of independent technical design review through evaluation of overall design quality, compliance with codes and regulations, and compliance with Terms of reference for developing the project design.
With the use of 3D BIM model, our engineers are able to comprehensively review the design, including both in detail analysis of each respective discipline and its relation to all other building elements.
We use detailed check lists to ensure comprehensive design review is done each and every time.
Inevitable part of Bexel Consulting’s independent design review is clash detection identifying inconsistencies between different trades.
Identifying all relevant design deficiencies and inconsistencies that need to be resolved, significantly improved design quality can be reached.
Design changes can take place during design review meetings bringing additional efficiency to the entire design process, while cutting down design time & cost and reducing risk.
Clash Detection
In traditional 2D design, spatial conflicts between elements of different trades are hard to detect. Therefore, they are often left to be solved at the construction site, which interferes with the construction process, causing delays and additional costs.
With developed 3D BIM model, we conduct clash detection analysis identifying every conflict and support their resolution in pre-construction phase, reaching fully coordinated design and eliminating unnecessary costs.
We develop Clash Detection Matrix defining required distances between trades and all clash tests that need to be conducted, in order to identify all conflicts and discrepancies in design, including:
- hard clashes – different building elements physically intersecting between each other
- soft clashes – required distances between elements are not met, which may interfere with technical regulations or good practice standards.
BIM Collaboration Format (BCF) is used to communicate clashes with design team since BEXEL Manager BIM platform fully supports BCF.
We analyze and prioritize clashes, creating detailed clash reports containing number of conflicts between different trades, descriptions, positions and visualizations of each clash in order to facilitate clash resolution.
Conducting coordination meetings with design teams we support resolution of all conflicts, and supervise the propagation of agree resolutions to all respected designs, in order to ensure smooth construction process.
Quantity Takeoffs
Based on the BIM model, our streamlined quantity takeoff processes and BEXEL software products, we are able to quickly generate highly accurate quantity take-offs, broken down by various criteria such as: buildings, spatial structure, zones, disciplines, etc.
Hierarchical organization of building elements within a BIM model, developed in any modern BIM authoring tool, organizational and functional data and precise three-dimensional representation of geometry and metrics, collected and organized, makes a detailed database, at our disposal to provide a number of answers to any imaginable question of interest, regarding material quantities. For example:
- What is the total volume of concrete, of a given type, needed for construction of basement walls?
- What is the total area of partition walls which needs to be painted on levels above a given level?
- How many fittings, accessories and equipment of each type are needed for water supply systems?
Bexel Manager software solution allows automatic generation of model based quantity takeoffs enriched with visualizations of each work item which improve understanding between stakeholders and eliminates misinterpretations of quantities and additional works.
Key aspects here are precision and time – thanks to complete automation and quality calculations, we are able to provide more precise take-offs than ever before and – in real time!
Having full integration with the BIM model, all changes and revisions are quickly absorbed and new quantities are available instantaneously.
Bill of Quantities
Bexel’s integrated approach includes use and continuous updating of complex market-adjusted cost databases that correspond to detailed and elaborated work breakdown structures which we use in development of our Bill of Quantities.
We use globally recognized standards for classifying building specifications and cost estimating such as MasterFormat or Uniformat as well as adapted WBS according to project’s specifics or Client’s requirements.
BEXEL Manager’s advanced cost engine allows fast adoption, BIM integration and use of any worldwide standard and cost database, as well as those traditionally used by our Clients containing their accumulated market experience. We enable cost database to include practically any quantity surveying or pricing rule such as:
- No quantity deductions for voids less than 1 m2
- Different pricing of concrete walls with height above 3 meters due to more complex formwork
With our developed quality control procedures, detailed descriptions of work items, and the superior insight into the project details that BIM model enables, our Bill of Quantities are precise, probative, and comprehensive.
Being supported with visualizations and different argumentation from BIM model, our Bill of Quantities lower Contractors risk margins, significantly reduce the number of RFIs, and finally minimize future claims, eliminating unexpected, additional costs related to work execution.
4D Intelligent Scheduling
Developing well-designed, complete and detailed construction schedule is very challenging task even for most experienced project managers.
Bexel’s intelligent scheduling engine implements advanced scheduling algorithms, specially designed to bring us the functionality of creating fully automated construction schedules and alleviate painful, manual 4D sequencing. Our software relies on the users to provide precise and meaningful data, defining construction norms and methodology – the rest is up to the software itself!
Using various intelligent scheduling tools and algorithms schedules can be automatically analyzed and customized to fit any need or criteria.
BEXEL Manager’s 4D BIM scheduling engine allows us to analyze the schedule in detail and reach important schedule optimizations, using all the advantages of BIM model such as:
- Precise quantification of each scheduled task through the link to specific building elements
- Visual location-based planning and Line of Balance diagram (LOB)
- 4D construction simulation presenting planned construction activities on a daily basis
- 4D analyses of the envisioned construction methodology, identifying timeline conflicts (workflow clashes, 4D clashes)
- Resource analyses and optimization
Initially generated schedules can be further fine-tuned by the user, by introducing specific ordering of phases and elements in either temporal and spatial sense, or implementing custom calendars for tasks and subcontractors. Resource quantities may be modified for any single task, subcontractor company or phase.
Finally, all task durations can be manually modified, before exporting the schedule to more commonly used Primavera™ or Project™ platforms.
5D Cost Estimation
Developing project design while having in mind targeted budget and time is of great importance for successful project execution.
Either we develop, or manage and monitor project design development, we constantly analyze cost effects of design solutions or proposed design changes. With virtually each building element being modeled, exact quantities can be taken off and precise cost estimates can be made to a detail level of brick and tile.
Bexel Consulting provides our proprietary databases of work item unit costs & norms, complying with North American, German or Russian standards. Our state-of-the-art cost engine also allows quick and easy adoption and integration of the clients’ legacy databases for full use in 5D BIM models.
BEXEL Manager’s advanced cost engine allows intelligent linking of BIM model elements with cost items from the cost database that is automatically updated with every BIM model update or change. This allows our engineers and managers:
- Fast development and update of cost estimations;
- Timely evaluation of designed solutions in terms of cost and resource needs;
- What if analyses of proposed changes;
- Precise Bill of Quantities of entire project, or any of its parts such as zones, subzones, disciplines etc.;
- Cash flow analyses on a monthly, weekly and daily basis.
Our integrated BEXEL Manager solution, combining 3D analysis engine, 4D scheduling and 5D cost engines provides great flexibility allowing our BIM experienced engineers to deliver comprehensively analyzed, optimized and target-oriented design solutions, and our project managers to plan construction process with respect to available resources, material procurement constrains, and agreed cash flow.
Resource Optimizations
One of key reasons for inefficient budget usage and frequent budget and projected construction time overruns comes from inefficient use of construction site resources – namely labor and equipment allocation. Not even the most experienced of project managers can sometimes arrange thousands of tasks and their assigned resources in a close to optimal manner.
Using our accumulated, expert project management knowledge and advanced scheduling technology, BEXEL’s teams were able to reach near optimal usage of labor and equipment resources on many projects of different scales, which, in synergy with many of our other expert services results in timely completion of construction and no money being wasted on additional salaries, rents, fuel or plain inefficiency.
We possess the expertise and technology to make sure that tasks are ordered and prioritized appropriately, cash flow charts are ironed out and that you never have to worry about having too much or too few laborers on your payroll, or if construction machines are rusting away. We take care about each single task so that project managers need not worry if work force assigned is over or under-allocated.
Spatial contexts of tasks are also taken into consideration – there is no point in assigning additional workers to complete certain jobs faster if laborers are stepping on each other’s toes. In a nutshell, BEXEL makes sure that you have just the right quantities of resources to complete the project in the right time.
Tendering Packages
Bexel develops detailed, precisely defined tendering packages, with clear work items descriptions and visually supported quantification. Our methods and technology ensure that all work items are handled precisely and no work items are left out from the packages or duplicated.
With developed BIM models, generated quantity takeoffs, and descriptions made by experienced Bexel’s engineers, we leave no space for waste, additional works or potential claims.
Our comprehensive tendering packages include various visualizations of design solution, 4D simulation of proposed timeline of construction execution, work breakdown structures of thousands work items, with all quantities supported with BIM model visualizations, and even BIM model itself.
Our tendering packages allow bidders to thoroughly examine envisioned object within usual time frame of tendering process, resulting with better commercial conditions in offers due to lower risk margins.
