Trimble has enhanced construction modelling capabilities for the HVAC (heating, ventilation and air-conditioning) market through new construction modelling workflows with enhanced integration between Bentley Systems’ AECOsim Building Designer software and Trimble’s Vulcan sheet metal cutting software.

The new workflow integration enables design models to be shared easily, securely and accurately, says the US-headquartered company. The move expands the companies’ ongoing collaboration around construction modelling and enhanced information mobility which includes a goal to leverage Bentley i-models when Trimble and Bentley solutions are used together in project delivery.

Vulcan is a sheet metal cutting software solution by Trimble for HVAC contractors, design/build firms and duct manufacturers, designed to increase shop productivity, reduce waste and improve their bottom lines. And AECOsim Building Designer is Bentley’s software for teams involved in the design, analysis, contracting, documentation and visualisation of buildings.

“Sheet metal cutting and fabrication require the utmost precision to ensure the finished product will meet design specifications exactly, but the design-to-fabrication gap is where errors are most likely to occur,” says Pat Bohle, general manager of the MEP (mechanical, electrical and plumbing) division within Trimble Buildings.

The platform leverages i-models for the open exchange of project information so that team members may share and interact with complex project data and across product lines and technology platforms. By extending Trimble and Bentley’s existing i-model integrations to Vulcan, users can directly transmit design drawings to sheet metal fabrication, which can reduce errors and rework, and ultimately save time and costs, according to the company.

“Trimble and Bentley share the goal of improving productivity and accuracy across construction processes, so we’re pleased that our collaboration continues to deliver significant and tangible benefits to the industry,” says Harry Vitelli, Bentley Systems senior vice-president, construction and field.

The new capabilities will be incorporated into Vulcan 2015 Version Two.
