ASSUMPTIONS
The above figures are based on estimated excavation schedules provided by Mike
Elliott for Phase I rough grading (45 workdays), Phase II rough grading (35 workdays),
and Phase III rough grading (90 workdays). The scope and cost estimates only cover
construction monitoring, project management, and final report preparation. They do not
cover specimen salvage, preparation, or curation activities. In the event that fossils are
unearthed and require recovery these tasks will need to be added to the mitigation
program through a change order.
Typically, the field time is been broken down into monitoring and salvage.
Monitoring involves looking for unearthed fossils, while salvage involves recovery of
fossils. Often these two activities coincide. Occasionally, however, a specimen will
require a more extended salvage and the assistance of an additional field person.
Screenwashing is also typically included as a separate salvage activity, as it
involves processing of selected sedimentary matrix samples for the recovery of small and
sometimes microscopic remains (e.g., small mammal teeth).
Fossil preparation is another typical task in a paleontological mitigation program.
Getting the fossils out of the ground is only the first step. They then have to be removed
from their enclosing rock matrix and stabilized so that they can be placed into a scientific
institution for permanent storage and/or display. Previous mitigation projects have
shown that, on average, preparation time equals approximately 30% of monitoring time.
Cataloging and storage represent the final phases of mitigation and result in production of
a specimen inventory of recovered fossils and permanent storage of the collection at the
Museum.
METHOD OF PAYMENT
The San Diego Natural History Museum will bill Standard Pacific Homes
