OHL (Obrascon Huarte Lain) is a Spain based multinational and civil engineering company. Their North American subsidiary, namely OHL North America is a leader in the heavy construction industry, and specializes in large public works projects such as tunnels, bridges, subways, and highways. Recent accomplishments include New York City’s South Ferry Station and the Second Avenue Subway Station, which Governor Cuomo applauded as an important and “transformative project.”

The company faced significant operational issues and organizational challenges due to internal process management that badly needed a technology makeover.

While known for their on-time delivery of large public works projects, OHL North America experienced the following hurdles that got in the way of their rapid growth:

  • With too many redundant business systems in place, it was difficult for OHL North America to manage critical business processes, user administration, system administration, end-user training and support. Departments used excel spreadsheets and outdated third-party applications for record keeping.
  • The company had to rely on third-party software solutions for all enterprise requirements, many of which just didn’t exist, didn't integrate with other systems, or failed to support the envisioned business processes.
  • Lack of a central hub for co-ordinating tasks and sharing information lead to a situation where internal communication fell through the cracks causing disruption to business.
  • The software products available in the construction domain failed to match up to the needs of OHL North America and due to this, workflows lacked cohesiveness and business suffered.


OHL North America had a growing need for a comprehensive software solution. With more than 3,000 construction employees and over 800 administrative employees on payroll, they needed an integrated solution that addressed the following business priorities.

  • Connect departments through centralized data sharing.
  • Track projects from RFPs and bidding to resource management and delivery.
  • Clear and precise record keeping and accounting with billing and payment tracking.
  • Scalable, multilevel, role-based workflow that enables employees with different roles in the company to perform different tasks seamlessly.
  • A straightforward solution that integrated project management, operations, resource management, and inter-departmental communication.

After a rigorous search for vendors who could build such a solution, OHL finalized our team based on our experience with similar staff augmentation projects.

"In the past 6 years that we’ve worked with Asahi Tech, we’ve found their service to be prompt, and of high quality. Trustworthiness, Diligence and Technical Proficiency have been the hallmark attributes of the team that worked on this project. I would like to convey my appreciation to the great work this team has been doing in automating and digitizing our business workflow processes. We look forward to continue working with them."

By setting up a staff engagement kind of setup with our team, OHL North America was able to quickly build a team needed to build an enterprise solution for its business. Our team provided OHL North America with an integrated ERP solution that connects departments through centralized data sharing.

Here are the key technology toolkits we used.

  • Telerik controls - To provide powerful UI capabities for all interfaces throughout the application.
  • PDF DLL To provide clean report generation capabilities from the various modules of the application.
  • Power BI To provide interactive visualizations and business intelligence capabilities through simple interfaces.
  • Antera To utilize its CRM and Order Management capabilities
  • UIPath To automate invoice and payroll processes

With no constrains around licensing costs, the solution allowed the company to add unlimited users with granularly defined access rights.

We succeded in providing the following additional tools necessary for every user to go about successfully executing his/her daily tasks in the organisation:

  • Cell phone and card request/approval with API integration
  • Power BI with advanced reporting
  • Document management solutions with hierarchy based approval
  • Bid tracker to manage the entire lifecyle of bids placed on projects by vendors of the client
  • Reduction of redundant, repetitive tasks through automation solutions.


The scalable solution we built for OHL eliminated their former reliance on disparate third-party systems. While providing full project tracking and resource management capabilities, the solution succeeded in centralizing the client’s record keeping and accounting processes.

Our ERP solution streamlined operations across the client’s multifaceted business. Users with different roles and privileges can now access vital operations data from the convenience of an intuitive web-based interface.


Our solution provides:

  • Multilevel, role-based online access for various users within the organization
  • Seamless inter-departmental communication to enhance co-ordination between distributed teams
  • Strong integration between various modules to allow for elaborate approval workflows
  • Reduction in human errors during payroll and invoicing process.

Our ERP solution cut OHL’s workflow time in half. As a result, despite the initial inertia from middle management, it was adopted widely throughout the organization in due course of time. For the client, this meant the following:

  • Departments are now fully interconnected.
  • Full visibility into crucial workflow, accounting, and project management information.
  • Replaced outdated paper based processes and legacy systems with a intuitive cutting edge solution.
  • Request, approval, and workflow are more accurate and 2X faster.
