PROJECT DESCRIPTION

Precast concrete and steel frame assembly, structural design, GA, WSD (shop drawings).Precast elements were delivered on the construction site of one of the largest (12 500 m2, 50 m hight) commercial projects in Sweden. Building frame is made with precast concrete structures including (415 pc):

• – sandwich walls with bricks
• – hollow core slabs
• – columns and beams
• – balconies
• – massive slabs

In general, our scope of design and engineering works to Clients include:

– FEM analysis (Dlubal Software RFEM), elements calculation, joints design (IDEA StatiCa)

– Structural efficiency optimization support

– Reinforcement, 3d detailing

– General arrangement, single part and workshop drawings for factory.

PROJECT DESCRIPTION

How do we work with precast concrete manufacturers.

Two types of clients approach our PMtech Group company for the design of precast concrete elements:
– Large factories that already have a well-established design-manufacture-delivery environment for precast products using high-precision digital tools;
– Companies that are just switching to the digitalization of their production.

How can we be useful to companies.
PMtech Group is fully integrated into your environment and rules. Our engineering team analyzes your design and manufacturing requirements.
In this case, a special guide and instructions for engineers are prepared with the accepted numbering system, reinforcement brands, standards (SS EN, LT EN, etc.), shapes, diameters, rules for modeling reinforcement and meshes, lifting and transportation. used hinges, a complete range of products and materials needed for production.

Depending on the platform on which the customer’s internal environment is built: it can be Tekla Structures with Trimble Connect (or a SharePoint project) or Autodesk Revit with BIM360, the initial conditions are agreed. Further development is carried out in a single environment with the customer and his engineering team. This approach allows information to be tracked to reduce guesswork and data loss. For precast or cast-in-place concrete contractors, this means reduced risk and rework throughout the life of the project, and the opportunity to significantly increase productivity in the office and in the field with better, more coordinated, and more timely information.

3D model checking and control for clashes 

Applying a “clash-free” BIM design is possible in very rare situations.

We were wondering about the required and adequate accuracy level of quality assurance in 3D model checking and control for clashes especially when it comes to its application in the real-life environment, at the construction phase for example. In most cases, the BIM model is handed over with several clashes when the site work is almost completed. The model must ensure no complex critical clashes occur in the multidisciplinary environment on the construction site.

The occurrence of minor clashes is not excluded in the BIM model. It may depend on some factors including initial software settings, numerous planning changes on the client-side, delays in the schedule, and decisions to be made yet.

PMtech supposes the success of the BIM case can be analyzed and assessed in the context of the whole project and a host of factors including less obvious and even deferred ones sometimes. We will be pleased to demonstrate a full version of the VDC BIM control and tell you about our capabilities in case of interest.

The clash detection checking of the model was performed (Solibri software)
– based on an object – underground parking (as a part of a residential complex that includes reinforced cast-in-situ structures, 22 floors);
– scope of work contained;
– checking for clashes;
– data analysis and reports review.

PROJECT DESCRIPTION

Clashes (intersections between objects or elements) result in costly time delays and material costs. They can be found on the construction site when correction is impossible or partially possible, but the best solution is to find intersections at the design stage and at an early stage. PMtech Engineering – highly experienced BIM team, that provides BIM project management services for the Scandinavian region.

There are several methods in the BIM strategy for finding clashes we use.
● BIM expertise, BIM consultancy: The first one is through the automatic model checking that allows us to detect most physical collisions and thereby save time for the construction planning with BIM requirement preparation (Navisworks, Solibri Model Checker).
● BIM coordination: In the process of algorithmic rules and manual verification by a specialist, intellectual collisions are revealed that have not been noticed by specialized programs and can only be detected based on the logic and experience of the employee.
