Prasad Dissanayake, PE

President and CEO

An environmental engineer by profession, in 1997 I embarked on a journey to build a company based on the core values of making positive contributions to enhance the quality of living environments of our communities through innovative and sustainable solutions. These core values also focused on building a team that called “work” as well as “home” a happy place. Over the years, as we have achieved many milestones on both these fronts, we continue to strive to be a better company providing innovative solutions to our customers in a rapidly changing world, while also striving to become better ambassadors to our communities outside of our work life.

As we have continued to set the bar higher and higher for our firm, it has always been through carful considerations to fostering a sustainable work place and a safety culture that is unparalleled. While these considerations have enhanced the “out of the box” thinking and productivity of our work force they have also resonated well with our customers.

Our corporate culture is focused on providing “above and beyond” solutions in this ever-changing world, to our customers. We continue to stay ahead of times by constantly combining creativity with our fundamentals.

In the years to come we will continue to enhance our company and our personal lives, building on our strong foundations and setting new benchmarks that are in line with our corporate vision.

HAZARDOUS MATERIALS & INVESTIGATIONS

Tidewater has over a dozen trained and experienced hazardous materials building inspectors and risk assessors to assist during building renovation or demolition in the Mid-Atlantic region. These inspections are typically needed prior to start of work to identify any hazardous materials that might pose an exposure concern to building occupants or the contractors performing the work. Disturbance of these materials might also require Federal and state permitting, use of licensed remediation contractors and specialized waste stream disposal procedures. This is especially true for facilities built prior to 1981, but can also apply to newer structures depending on their use and history. These complications can have a serious impact on project timelines and costs.

• Asbestos-containing materials and lead-based paint or lead-containing materials
• Polychlorinated biphenyls (fluorescent light ballasts, transformers, electrical equipment, etc.)
• Mercury thermostats, switches, fluorescent light tubes, etc.

TIDEWATER’s SeaPort-e QUALITY ASSURANCE PROGRAM
Our Corporate QA/QC program provides the framework for establishing quality measures, monitoring performance, enforcing quality processes, and achieving continuous improvement. To maximize efficiency for SeaPort-e task orders, we have tailored our approved Corporate QA/QC Plan to satisfy Navy / Marine Corps contractual requirements, incorporate it into all phases of the contract, and use it as the guidance document for managing quality.

Tidewater has established QC procedures to control task order activities, using approved plans and processes that have been successfully approved and implemented for our previous and current NAVFAC contracts. We use a structured approach to quality management that incorporates a three phase QC process of inspections, testing, and controls. Tidewater’s approach to quality management is based on five key principles:

All staff whether working for the prime contractor or subcontractor understand and commit to the quality principle known as DIRTFT—Do It Right The First Time.
Project Managers are trained to be constantly vigilant for any deficiencies in operations that might result in a reduction in quality for any project-related process or task order deliverable.
Quality triggers represent points in Tidewater’s process management that alert Project Managers to a potential process breakdown that could threaten the quality of deliverables to the Navy / Marine Corps.
Quality triggers are established for both management of project information generated by office staff as well as data gathered by field personnel at the project site.
Deficiencies identified through quality management must be addressed through Corrective Action Plans. (CAPs)
