Design-Build Services

For building owners, developers, and architects desiring to streamline their construction process, Rens Welding & Fabricating offers unique build services that blend the structural steel detailing and Fabrication processes to expedite project schedules. Our team of experts working with your design team can cut up to 2 months from your project timetable.

Our Detailing, Fabricating and Installing knowledge provide unparalleled guidance early in project development. With a deep understanding of construction costs and schedules, we facilitate important decisions to fast track critical foundation and steel construction components.

Rens Welding & Fabricating executes the steel scope of work to save valuable time in critical path trades. We work with your design team to enable the foundation work to commence early by assisting in driving key design decisions that permit release of an early foundation design. Our model allows the rest of the project to be executed in a build process assuring it is built competitively to achieve the best value.

A unique approach captures the advantages of the traditional design-build model, while eliminating many of its disadvantages.

  • Key decisions are made with the owner, architect, and general contractor early in the development stage to establish column grids and lateral and foundation systems
  • Our knowledge and experience create cost- and time-saving approaches that generate faster schedule sequencing and details
  • We assist to develop an early foundation package to allow site work and foundation construction to proceed ahead of detail and finish work
  • Your design team designs the primary structure while allowing flexibility to adjust canopies, parapets, and other accent features
  • As the design is finalized, Rens Welding & Fabricating provides steel construction value and proceeds with the detailing process ahead of final design drawings
  • Rens Welding & Fabricating takes full accountability for the accuracy of the steel shop drawings and the coordination with the architect
  • Once design is complete, Rens Welding & Fabricating constructs the metal structures in its state-of-the-art facility and installs them at the job site

Our process cuts time from your production schedule that achieves substantial cost savings (see figures 1 and 2 below). For building owners, it adds to building lease time and enables earlier commitments to lessee occupancy dates. It also reduces lost operations time for business owners.

Apple Store, Market Street, Lynnfield MA

Fast-track project. Custom tapered girders to create thin-profile hip roof. Client pushed for early mobilization ASAP. We communicated to project team the benefits of allowing us to take an extra week to fabricate large roof truss assemblies to limit erecting time. This enabled the project to gain an extra two weeks of schedule by accelerating additional concrete work for underground MEP that otherwise had to start after steel erection.

Custom Monumental Stair, Boston MA

Dunnage frame on existing building. Fast-track project. Fabricated the 10’-0” wide stair in 4 sections that weighed over 12,000 lbs each to limit install time and accelerate the overall project schedule.
