within the schedule of the build as a whole. The reliability and consistency of prefabricated
panels or blocks are of great benefit in large-scale commercial or industrial applications,
where the predictability of how the material will 'behave' once applied on-site allows for
reduced costs, and is much easier to fit into a complicated, and often financially critical,
schedule of works.
Hempcrete cast up against an outer skin of hempcrete blocks - combining some of the benefits of
the pre-cast and cast-in-situ methods.
The cast-in-situ method, on the other hand, has the advantage of reduced labour costs be-
cause the casting and on-site construction are collapsed into a single process. The process
of construction is also simpler, and is achievable with minimal mechanization. Cast-in-situ
hempcrete, if it is hand-placed, needs only a mixer and a chain of people to ferry buckets of
hempcrete, rather than (in the case of large pre-cast panels) a production plant, machinery
for drying, and heavy machinery on-site to hoist the panels into place.
