The unique aspect of the design/build project delivery system is that the construction
professionals are intimately involved with the project from its inception. Unlike
CM-at-risk, the design/build approach requires that the constructors be involved
from the very beginning during the development of design concepts and the schematic
design, where construction input can have the most meaningful impact, that is, the
highest value, on the project design.
PKA is genuinely committed to teamwork on all projects, and has embraced the design-build
approach as the delivery method providing the best opportunity for the application
of teamwork. Working with trusted construction managers, fabricators, subcontractors,
suppliers, architects and engineers, the design-build process provides an environment,
from the start of the project, for the honest and respectful sharing of ideas and
concepts, and the discussion of materials, methods and systems from which a consensus
can be reached for the implementation of selected building systems.
PKA has particular expertise with design-build project delivery. Structural engineering
as part of a design-build team has been a major part of PKA’s work since the inception
of the firm. The design-build approach to construction provides an opportunity for
genuine collaboration in the consideration, evaluation, selection and detailing of
project structural systems. PKA works and coordinates with the builder and his fabricators
and subcontractors to select, design and detail structural systems that suit the
construction team’s particular experience, expertise and capabilities, and the functional
and architectural requirements of the project, as well as the proposed project schedule
and construction sequence.
During design, PKA communicates and coordinates with the architect and other consultants
to address issues such as roof slopes for drainage, structural depths, floor to floor
and floor to roof heights to accommodate ceilings, ductwork, lighting, conduits,
piping and cabling, routing of underslab utilities and grading around the buildings
with regard to their impacts on the structure.
The design-build approach to construction is often considered to mean that the design
team can produce construction documents with less detail. However, it has been PKA’s
experience that the design-build approach requires production of fully detailed structural
construction documents. The design-build delivery system is often selected due to
concerns about schedule and budget. Preparation of complete, accurate and thoroughly
detailed drawings ensures good pricing with minimal contractor and subcontractor
allowances for contingencies, and permits the timely production of shop drawings
and submittals, with minimal lost time for processing requests for information or
clarifications to fill in the “holes” or “gaps” in the drawings.
During construction, PKA works closely with the construction contractor and subcontractors
to expedite the review of submittals and requests for clarifications or information.
PKA also works closely with the constructors to correct and resolve any field errors
that may occur during the course of construction. Support of the team during construction
is one of PKA’s strengths.
PKA has served as the structural engineer for design-build teams for projects involving
industrial manufacturing, office buildings, retail buildings, sports facilities and
public and institutional projects.
