Special Construction
|
| Projects having special design and
construction requirements include shoring and underpinning designs,
heavy equipment foundations, retaining wall structures, automatic
storage and retrieval buildings (ASRS), and designs complying with
nuclear safety related structures.

Retaining Wall - Rochester
Institute of Technology
|
 Extensive
steel corrosion and settlement resulted in the need for replacement
of the retaining walls, bridge approach apron, and column supports
for the pedestrian bridge. |
 Special
shallow foundations were designed to stabilize the new construction
on poor soils. Corrosive resistant reinforced concrete materials
were specified for strength and durability.
Uncharted underground utilities presented interesting challenges
during construction. |

Wood deterioration at the lower level of a heavy timber column,
which supports five floor levels, was remedied by removing a section
of column and the construction of a new concrete pier and footing. |
|
Structural design for the new lobby and open wall elevator
required that sections of the building foundations be lowered.
Shoring and underpinning procedures where engineered. Steel framing
supported the two-story lobby construction |
|
Constructed in 1920, the reinforced concrete school
building was converted to medical offices. This required the
addition of a new floor level in the gymnasium and the extension of
existing building foundations to accommodate new office space below
grade. |
 Interior
building columns and exterior walls were shored and existing
footings removed. A 10-foot high clear space below grade was
constructed for medical offices. |

 DRC
Associates provides structural engineering for Automated Storage and Retrieval
Building systems (ASRS) throughout the United States. Engineering commissions
include foundations, rack design, or combinations of both.Tall structures
without floors, ASRS buildings consist of storage racks constructed with truss
like vertical components. Foundations are typically concrete mats bearing on
soil or on piles.
 The
selection of super flat and flat floor construction is based on
operational considerations.
Freezer and refrigeration storage buildings are common uses for ASRS
buildings.
3D element and finite analysis together with graphic engineering
achieves economy in design, detailing, and construction.

 Tritium
facility was designed by Bechtel International for the Department of
Energy and constructed by Bell Technologies, Inc.
Working with the contractor, the stand-alone construction aid
steel was engineered to support the stacking of steel wall shields
and accessories. |
 All
major accessories within the wall configuration were modeled to
produce a scaleable electronic 3D layout.
The electronic model became the field reference for installation
and the base line for producing shop fabrication drawings. |
