Reference Number: AA-00204 Views: 4708 Created: 01/11/2016 11:35 am Last Updated: 02/13/2020 09:08 pm 25 Rating/ 2 Voters

These System Requirements are for Oasis Takeoff.  If you are looking for System Requirements for our Classic product line (On-Screen Takeoff, Quick Bid, and Digital Production Control), see CLS - Classic System Requirements.

Operating System


Windows® 10 Pro x64


Windows® 10 Home

Windows® 8.1 Pro

On Center recommends 64-bit Windows for Oasis Takeoff because it can address more RAM.  32-Bit is supported but will not provide optimum performance.

Oasis Takeoff cannot be installed in Terminal Services or Citrix (or similar) environments.

Windows 7, Server 2008, and Server 2008R2 are not supported, there Extended Maintenance with Microsoft ended on 1/14/2020.  

CPU (Processor)


Intel Core i7 (or equivalent/better)


Intel Core i5, or equivalent/better


Intel 1GHz+ processor or equivalent - this is the absolute minimum required for viewing plans/annotation and will not provide acceptable performance

ARM Processors are not supported

Memory (RAM)


8 GB RAM or more (requires 64-Bit Operating System)


4 GB RAM (3GB for 32-Bit operating system)

Hard Disk Space


500GB SSD or SSHD Hard Disk Drive (or larger)

Oasis Takeoff caches information (Bid data, Plans, User Settings) on your hard drive.  Depending on the number of Projects/Bids you access and the number of Sheets/Plans contained in those Projects/Bids, the amount of hard disk space used/required will be substantial.  A cache of 20GB or more is not uncommon if you access numerous Projects/Bids with a large number of Sheets/Plans.


Minimum: 1 GB Hard drive space (plus more for plans, projects) - a single project may require several GBs of disk space, depending on the number and size of the project Plans.  Oasis Takeoff stores several formats of each Plan on your local hard drive to improve performance.

Display Resolution


1920x1080 (HD) Single, Dual, or Multi Monitor Displays


Minimum display resolution: 1280 x 1024

Other Requirements

  • High-speed, "always-on" internet connection (some WiFi connections are not fast enough). (See OTK - Configuring your Firewall (Oasis Takeoff) for information on configuring your firewall).  On Center cannot provide a specific "speed" that will work because we do not know what else is using your Internet connection, what sort of security software is employed, or how many users are using your connection.  As a rule, for a single user, on a dedicated connection, nothing else running...3MBps up/down should be sufficient - obviously, that is not close to being fast enough for an office of 5, 10, or 20 users or even a single user with multiple cloud-based products running (or streaming video/audio).
  • Windows Update: Microsoft .NET Framework 4.5 or higher (included with Windows 8 and higher)
Minimum system requirements support very basic functionality only. Your actual system requirements will vary, depending on your system configuration, network speed, other applications installed and running on your computer, and the complexity and size of the electronic plans you use. Please follow the Recommended system requirements for optimum performance.

Apple Computers

Devices running MAC OSX

There are two environments in which Oasis Takeoff may be installed on an Apple computer running MAC OSX:

  • Bootcamp - this is a separate partition from MAC OSX on which a stand-alone installation of Windows is running.  This allows the user to run Windows OR MAC OSX but not both at the same time.
  • Parallels (or any other locally installed virtualization product) - this allows a MAC OSX user to run a virtualized installation of Windows within the MAC OSX environment.  This is not a stand-alone installation of Windows, it is sort of running Windows within a window, so to speak.

Devices running iOS (Mobile devices)

On Center is pleased to offer Oasis FieldCenter™ - designed for field workers who use iPads.  Please visit our Web site for more information: https://www.oncenter.com/oasis-platform/oasis-fieldcenter or contact your Account Manager at On Center.  Oasis Takeoff cannot be installed on an iPad.
