Future Revenues and Expenses (Total cost of ownership)
Aviation Maintenance anticipates minimal impacts to operating and maintenance costs, as a
result of the scope of work in Phase 4 of this project. In Phase 4, four sets of restrooms are
being built and three sets of restrooms are being renovated.
ADDITIONAL BACKGROUND
Budget Challenges
As mentioned above, the budget for this five-phase project has increased from an original
estimate of $38M to $62M. Major impacts to the budget included:
(1) Complications during construction of earlier phases. Phases 1 and 2 faced significant
unforeseen site conditions such as interfering system infrastructure transiting the
project sites, and underground building structural components that were not
documented in the building records.
(2) During the project, the Port’s design standards changed, and the impacts of these
changes were not reflected in the budget. One example would be the incorporation of
“ambulatory” toilet stalls, which provide greater maneuvering room for users but also
require additional space and therefore a larger restroom to provide the same number
of fixtures and can result in higher costs. This was also true for the addition of
inclusions like the initiative-driven All-Gender Restrooms, mother’s rooms, and adult
changing tables all of which were not included in the original estimate and cost more
compared to the original project estimate.
(3) The impact of the bid overage on Phase 3. The bids for Phase 3 exceeded the
Engineer’s Estimate by 65%. The bids were reflective of the construction market and
have also influenced the estimates for the remaining work in Phases 4 and 5.
(4) Spaces newly allocated for additional restrooms required more infrastructure
improvements than first anticipated. Additional plumbing, air distribution and exhaust
venting, and electrical for lighting and touchless features increased the project costs.
(5) COVID-19 added changes during construction.
Lessons Learned
The project team has developed a list of lessons learned in the development of the project.
These include:
(1) Investing in preliminary design (10-15% design) before finalizing a project’s budget.
The Airport has now adopted the use of Project Definition Documents (PDD) for this
purpose on large or complex projects. The PDD can include more thorough site
investigation where needed.
(2) Employing change management to address budget impacts of initiatives inclusion. The
Airport has now adopted a more formalized change management process which
requires project teams to calculate the cost impacts of changes, communicate those
impacts, and seek approval at a senior management or executive level (depending on
the cost) before implementing.
