OpenSite Designer is a native 64-bit application. 

 

Operating System 

Windows 11 (64-bit)/ Windows 11 (21H2) - Home, Pro, Enterprise, and Education 

Windows 10 (64-bit)/ Windows 10 (21H2) - Home, Pro, Enterprise, and Education 

Bentley does not support its software running on Microsoft operating systems versions that Microsoft has "retired". For more information see Microsoft's application retirement policy and the Bentley Application Support Lifecycle 

 

Processor 

Intel or AMD processor 2.5 GHz or greater 

 

Memory 

16 GB minimum, 32 GB recommended. More memory almost always improves performance, particularly when working with larger models. 

 

Hard disk 

Minimum 25 GB free disk space (Minimum 42 GB disk space if additional companion applications/products included) 

 

Video 

See the graphics card manufacturer for latest information on DirectX drivers. 1024 MB of video RAM or higher is recommended. If insufficient video RAM or no graphics card supported by DirectX can be found, OpenRoads Designer attempts to use software emulation. For optimal performance, graphics display color depth should be set to 24-bit or higher. When using a color depth setting of 16-bit, some inconsistencies will be noted. 

 

Screen resolution     

1920 x 1080 or higher 

 

MSAccess 64-bit engine 

To connect to an Access database, you must download and install the Microsoft Access Database Engine 2010 Redistributable. Use the following link to download and install the MS Access Database Engine 2010 Redistributable. This is required for access to gINT projects and for the ability to Import InRoads drainage files.

FAQS

Find answers

OpenSite Designer is an application made for site design and engineering. You can create and optimize multiple design scenarios in days, not weeks. Using auto-drawing capabilities and dynamic 3D modeling, conceptualize and detail building pads, parking lots, sidewalks, streets, and other design features. OpenSite Designer includes OpenSite SITEOPS. 

The price of OpenSite Designer varies per region. While there are various types of licensing available, a common choice is the 12-month practitioner license offered through Bentley’s eStore. When you purchase through the eStore, you get a Virtuoso Subscription. This means you get the software and “Keys” (tokens) to redeem for training and services. 

Site design software helps civil engineers plan, model, analyze, and deliver land development projects. It supports site layout, grading, drainage, utilities, and required documentation using model‑centric workflows, enabling teams to evaluate feasibility, refine designs, and produce construction‑ready deliverables from concept through detailed design. 

Yes. OpenSite Designer supports conceptual, preliminary, and detailed design in one application. Its site layout tools follow civil engineering standards to ensure feasibility. As an all‑in‑one solution, it supports parking and building layout, earthwork grading, site design, ponds, sanitary and stormwater networks, subsurface utilities, construction documentation, and staking reports, covering end‑to‑end site design needs. 

You can produce a complete array of 2D and 3D design deliverables with automated drawing production tools to produce high-quality documentation. Since all deliverables adhere to project standards and are created from the same model, you can be confident of your deliverables. OpenSite Designer provides design, volume, and analysis in industry-standard formats for data exchange and reporting. 

OpenSite Designer provides an open modeling environment allowing you to integrate data from different disciplines to improve collaboration and ensure all users are working from the latest model in all phases of the design. Working in the live model using the data interactively reduces risk, and working with site, rail, road, bridge, drainage, subsurface utilities, geotechnical, and other design teams helps identify conflicts earlier in the process and eliminate construction errors and delays.

Yes, OpenSite Designer is a built-for-purpose site design application and provides 3D modeling for site designers to elevate single-family residential design and layout to ensure an integrated multidiscipline workflow and increased return on investment. The software’s auto parcel creation technology helps designers create detailed designs while identifying project risk points.
