DESIGN FEASIBILITY ANALYSIS | Utilizing BIM allows C.D. Smith to make informed decisions with the design team to protect the facility owner's needs and intents when identifying key building pinch-points which could end in costly or undesirable changes later.
DESIGN CONFLICT CHECKING | C.D. Smith works alongside the design team to ensure that the coordination of items keeps up with the revisions to the design by consolidating all models and reviewing them through collision detection.
MODEL QUALITY CONTROL | Models that are received from the design team are reviewed to ensure they contain all the elements of the building for scope verification, coordination, and model turnover. We also delve into the accuracy and precision of the object's information, and enhance the models if needed for other preconstruction aspects such as splitting elements of the building up for more accurate scheduling or quantity extraction.
CONSTRUCTABILITY REVIEW | During a review for constructability we'll verify the model versus the details to catch any discrepancies or oversights, items that pass-through building elements for optimal placement, the access and feasibility of installing or replacing large equipment, component positioning not matching up between different trades, and the accuracy of any existing work being tied into, just to name a few.
QUANTITY VERIFICATION | C.D. Smith uses the A/E models to validate the material quantities needed for the project. Not all quantities will be in the models, such as some finishes, but we can gather the larger quantities and check them against our other takeoffs to uncover anything else previously missed.
REVISION TRACKING | Model revisions are received well before paper documentation of the revisions. These changes are tracked by highlighting the models differences whether it be dimensional or informational. This allows us to visually see the changes regardless of it being clouded as a revision on the plans or not, ultimately speeding up the work flow rather than waiting on the documentation to be fully completed.
SITE LAYOUT AND LOGISTICS | C.D. Smith illustrates the placement of field trailers, construction fencing, material stockpiling, equipment movement and range, concrete pumping procedure, delivery routes and best crane pick location. This clarity is essential for a confined site to streamline the construction process, and it reveals any potential issues regarding the protection of pedestrian traffic and equipment operators' line of sight. A visually conveyed layout and plan for traffic, pedestrian, and construction circulation lends a hand to project safety.
SIMULATION AND SCHEDULING | C.D. Smith puts together a construction schedule that is then tied to the model elements to simulate the construction process on a real timeline for the project. In doing so, issues in the order of work are discovered and adjusted. Construction project managers can visualize how they match up to the schedule and improve upon the situation. The subcontractors are able to plan their prefabrication shipments based on the visual schedule.
TRADE COORDINATION AND CONFLICT SCHEDULING | All major subcontractors model their scope of work, and all trades' models are combined into a consolidated model be C.D. Smith. Collision detection is run on the consolidated model to finding where multiple building elements are trying to utility the same space. Coordination meetings are then held by C.D. Smith where all issues between trades are reviewed, discussed and revised, until collision-free and there is complete confidence in constructability without field changes. This process cuts down on the amount of time needed for installation, improves site safety by cutting down on the amount of cutting done in the field, improves relationships due to eliminating field collisions, lessens the amount of time put into rework and the cost of materials that would have otherwise been wasted to resolve those issues
FIELD BIM ASSISTANCE | C.D. Smith reinforces project communication by using the models during the construction process with the field personnel. They have the assistance of printed 3D building cuts, 3D color-coded and dimensioned plans for quick layout reducing time for cross-referencing of information. 3D model files are also provided with viewers so the field personnel can check on their own inquiries. Important component locations can be loaded into their total stations for Geo-positioning to assist in quicker project layout for items ranging from concrete form work to pipe hanger locations.
PREFABRICATION | Due to the 3D trade coordination process, all shop drawings are produced straight from the contractors' models. Having confidence that all trades will fit nicely together in the field, they can grab all the quantities of each part in the models, and prefabricate almost all their work. They label them with numbers and deliver them to the field with a map of how the pieces get assembled. This allows them to track their materials and make certain they are not lost or used unwisely. For the subcontractors that are not up to speed with BIM, C.D. Smith, having worked through the issues with the design models, can assist in prefabrication and installation drawings on the subcontractor's level.
AS-BUILT MODEL TURNOVER | C.D. Smith gathers all as-builts in model form, updates the coordination model with the as-built changes and delivers the completed virtual representation of the building to the owner. This model can also be populated with operational and maintenance manuals, cut sheets, testing reports, serial numbers, expected replacement dates and more that will be used by the Facility Managers.
FACILITY MANAGEMENT DATA LINKING | C.D. Smith, depending on the owner's needs, can link real-time information to the model. It can be linked to the owner's computer-aided facility management system to provide work order submittal linking to the location in 3D. It can also be linked to building automation systems providing data such as real-time energy usage statistics, variable volume air handling, security/alarms, and lighting.
Virtual Construction Approach
C.D. Smith utilizes a variety of building information model management software platforms to virtually construct planned projects and simulate the construction process on a 3D digital representation of the facility, integrating modern technology with field labor. This process assists in communication, sheds light on items typically overlooked, and enables accurate off-site fabrication lending to eliminating waste in materials, rework, schedule and productivity, and improving on-site safety.
Our virtual construction process begins with the building's program and schematics. We set standards throughout the design modeling process, review the models to ensure data reliance, add additional data ourselves to leverage the models heavily throughout the preconstruction and construction phases, and provide the owner with a full navigational digital as-built at project completion. Besides using it for our own benefit, we lend expertise to sub-contractors for streamlining prefabrication, assist the field in day-to-day construction inquiries, and work with building owners and facility managers to integrate daily operational data, maintenance tracking, and work order submittals through use of the model.
