NTUA Business Plan

NI Solutions Inc. was hired by the Navajo Tribal Utility Authority (NTUA) to develop a broadband communications business plan and assist with grant writing to enable the NTUA to build a communications network capable of offering all residents’ cost-effective, high speed data services with full interactive capabilities. The network will also be capable of providing utility solutions such as automated meter reading (AMR), supervisory control and data acquisition System (SCADA) and Voice over Internet phone (VOIP). Sections of the business plan include the following:

  1. Review existing Technologies Study

  2. Identify the internal and external telecommunications needs

  3. Modify existing Digital Microwave and replace it with a fiber optic backbone where feasible

  4. Identify potential telecommunications service providers for resource sharing.

  5. Prepare overall cost estimates

  6. Prepare revised financial (revenue) projections

  7. Identify constraints and assumptions

  8. Identify and evaluate current fiber facilities available for purchase and/or lease.

  9. Grants Opportunities – NIS assisted the NTUA in acquiring funding from the National Telecommunications Information Administration (NTIA) for a $46 Million Dollar Broadband Technology Opportunities Program (BTOP) Project. The project was a part of the American Recovery and Reinvestment Act of 2009.

 

NTUA Detailed Fiber Optic Engineering Design

NI Solutions assisted the Navajo Tribal Utility Authority (NTUA) in developing a detailed fiber optic engineering design. The build out includes over 550 miles of fiber optic backbone and approximately 20 miles of laterals and spurs. The plan included fiber optic engineering, electronics, and training. Listed below are details of the tasks associated with the design:

  1. Fiber Backbone & Lateral Design

  2. Provided detailed engineering design of the proposed route.

  3. Manage testing of electronics and Microwave links to insure compatibility and functionality with the fiber optic backbone

  4. Perform a post implementation review process including an analysis of how the deliverables resulting from the Project measured up against the Project Post-Implementation Performance Factors established for such Project. The post implementation review was conducted by NIS Professional Engineers licensed in the State of Arizona and New Mexico

  5. Establish Change Control Procedures by which NTUA may request enhancements, customizations, interfaces, modifications or other changes to the Project by specifying the desired changes to NI Solutions. Such procedures will include the performance of an analysis by NIS and required that no change be made until a written change order describing the change was approved by the NTUA. In addition, such procedures enabled tracking of ongoing scope changes to the Project, and provided a basis for auditing scope changes to the Project. Project changes (including necessary changes, if any, to resource requirements or schedule for the corresponding Project) was documented by NIS and approved by the NTUA.

  6. Identify contractor requirements for Training were met, and to the extent requested by the NTUA, participating in the training.

  7. Emergency and Urgent assignments were resolved in a timely manner and NTUA was informed of any situations that required the NTUA to move the project ahead of schedule requiring resources on an extremely tight timeframe.

  8. Assisted in training sessions as needed describing the features and technologies being installed

  9. Coordinated all meetings to make sure the construction met the design requirements of NTUA Contracts.
