Cold Storage Project
Design and construction of an underground storage
facility and fermentation cave for Honey Rock Landing, an Orchard near
Delta Colorado. This construction included excavating two 80’x30' bays in the Entrada sandstone, followed by the development of a 8’x7’
portal and a 3:1 decline into a 80’x13’ fermentation cave approximate 20’
underground.
Underground Hotels
The firm is currently working on the permitting and
planning to re-develop the historic Silver Crown mine into an underground
hotel for the owner. Full underground design has been completed
including 3 new portals and portal sets, a 100'x20’ central room, 12 bed
rooms with facilities and over 400’ of underground drifts and
tunnels. Design also includes surface facilities including trout
ponds, building sites, retaining walls, avalanche controls, and access
roads The facility is currently in permitting with the State of
Colorado and Corp of Engineers. Miners and staff expect construction
to being in 2023 and last over 3 years.
UNDERGROUND VRBO'S
Design along with underground and surface construction
of a Berber style Vacation Rental (Cave Haush) at Honey Rock
Landing. The facility includes a 40’ long entrance tunnel into a 34’
diameter central room open to the surface 30’ above the floor. Off
the central courtyard are living quarters including dining room, kitchen,
4 bedrooms with bathroom all excavated underground by B.K. Briggs miners.
Ventilation and Ground Control
• The firm recently completed the Deep Creek Mine ventilation and ground control evaluation for the owners of the Deep Creek Mine near Telluride, Colorado. Portions of the Deep Creek mine workings have been used over the past 15+ years as artist studios by various artists living and visiting Telluride. San Miguel County has requested the owners have a professional mining engineer complete an evaluation of the stability and safety of the mine for it to continue to be used in this fashion. Following the approval by the County miners from the firm will begin installing portal sets, ground support and ventilation fans and stoppings. This work is expected to continue for many years along with new development planned for 2023-24 to expand the number of artist studios and entrance points to the mine.
