and again after 20 years. This cost differential is for the coating material and labor. $2,145,000
in project funding would be needed.
Pros:
(1) An entirely new 10-year roof-roll-on coating, replacing the security ladders, gutters
and adding a fall protection system investment will protect our assets and have a 10-
year life span.
(2) Helps to assure a stronger positive tenant experience and avoids potential safety hazards.
(3) Provides protection of Port assets.
(4) Increase safety with the installation of fall protection.
(5) This project would provide a warranted roof coating that will minimize the cost of
repairs going forward for the foreseeable life of the roof.
Cons:
(1) Additional cost for the roof coating is higher than the PVC roofing system (Alternative
4). Due to the added material, handling cost, and the need to re-coat the roof three
times as compared to the 30-year roof. This is the most expensive alternative.
(2) This alternative uses $2.14 million of capital that might otherwise be made available
for other uses on other projects.
(3) The cost of a future roofing project in the event of roof failure would be higher, which
would include the cost of this request and costs associated with escalation,
implementation of emergency work, lost revenue, and equipment and property damages.
This is not the recommended alternative.
Alternative 3 – Replace the entire existing roofing system with a PVC Membrane Overlay that
has a 30-year life while installing a new security ladder, gutter, and fall protection system;
additionally procure and install solar panels and required structural upgrades to 100 percent of
the building.
Cost Implications: An additional $5.53 million (consisting of structural upgrades of $3 million,
solar panel costs of $2 million, and approximately $530,000 in infrastructure upgrades) is
required to complete structural upgrades and include solar panels. This cost is above and
beyond the base cost of $1.56 million for Alternative 4’s investment.
Pros:
(1) Photovoltaic (PV) installation could potentially provide and generate approximately
300,000 kWh of power per year with the current usage being 291,800 kWh per year.
(2) PV installation could potentially save approximately $23,008 per year.
(3) PV installation would have a one-time state rebate (5%) and federal incentive (30%)
for the solar panel portion of the project only.
(4) Replacing grid-produced electrical energy with renewable energy reduces greenhouse
gas emissions by approximately 7,680 lbs. of CO
2
/year.
(5) Providing renewable power systems meets three Century Agenda goals: Reduces
greenhouse gas emissions, increases renewable energy use, and conserves energy use
to meet overall energy demand. Plays a role in building clean infrastructure and
