Construction Engineering Firm

Cranes

McLaren’s Construction Engineering team offers full-service crane engineering services, from planning and plan/calculation preparation to in-house expediting to handle all filing and permitting needs (NYC CN Applications).

Whether it be the need to develop a new crane plan or a peer review of a plan prepared by another firm, our team brings the requisite expertise needed to ensure your crane plans are complete, code compliant, and have considered all aspects of the intended pick. As such we take into account crane placement and configuration, pick loads and center of gravities, pick criteria and radius, geometry and clearances, outrigger reactions and track pressures and corresponding dunnage/cribbing design, rigging criteria/specs and design needs, and project schedule and constraints.

In addition, our experience with plan requirements and permitting processes with governing agencies (i.e. NYCDOB, NYSDOT, NYCDOT, NJDOT, MTA, MNR, AMTRAK, etc.) results in quicker reviews and approvals.

• Mobile Cranes
• Hydraulic & Lattice Boom Crawler Cranes
• Tower Cranes (Favco, Potain, Leibherr, Wolfkran & more)
• Derricks (Stiff-leg & Guy)
• Peer Reviews
• Inspections
• Permitting with NYC DOB

Rigging + Heavy Lifts

Our team of construction experts offer complete rigging solutions to service material and equipment handling needs, from shop to field installation. Beyond the design and check of a sling or shackle, we can develop step-by-step sequential drawings to illustrate the movement and/or transfer of a load throughout the rigging and installation process.  Each project takes into account piece geometry, field constraints, and all loading conditions.

• Mechanical & Rooftop Equipment Rigging
• Long-Span & Curved Girder Rigging
• Custom & Off-The-Shelf Spreader Beam & Lifting
• Skate & Roller Systems
• Load Transfers (i.e. crane hook to interior gantry’s or slide skates)
• Interior/Enclosed Space Rigging
• Hydraulic Gantrys & Slide Rails
• Counterweighted Picks to Handle Eccentric Pick/Drop Points
• Self-Propelled Modular Trailer (SPMT) Plans

Steel Connection

Connections between structural members are a critical part of any steel structure and their proper treatment is an essential component of safety and cost.  Our construction engineering division has intuitive knowledge of how a system will transmit loads, loads paths, and a deep understanding of structural mechanics to provide both safe and economical designs.

Steel connection design for structural steel projects includes standard shear connections, non-standards connections, moment connections, bracing, trusses, high seismic, and custom specialty conditions.  McLaren’s unparalleled experience is the foundation for developing and delivering the most economical, safe, and structurally efficient connections.

• Standard Shear
• Non-Standard Shear
• Moment
• Axial
• Splices
• Heavy Trusses
• Braced Frames
• Retrofits & Reinforcing of Existing
• Existing Beam Reconnection
• Hardened Structures & Blast Mitigation Design Connections
• High Seismic (R > 3)
• Specialty Conditions
• Pre-Detailing Assistance
• Value Engineering

Miscellaneous Metals + Delegated Design

We provide Specialty Structural Engineering Services (SSE) for a wide array of standalone miscellaneous metals and delegated design items. With constant pressures on construction costs, schedules, and fees, Structural Engineers of Records (SEoR) are required to do more with less and look for ways to shed design scope.  This has resulted in moving away from the more typical and straightforward design-bid-build environment of the past. As such, bringing on an SSE in the early stages of the project has never been more critical in project success.

Today, SEoR’s are delegating more design items than ever before. This includes secondary structural elements (stairs, guardrail, davits, elevator rails, cladding, etc.) as well as primary structural elements (steel joists, metal deck, precast concrete, etc.).  Unfortunately, this places a large burden on the miscellaneous fabricator which may not be transparent on the construction documents. McLaren’s construction engineering division has developed a sound reputation for producing quality, knowledgeable, and efficient end product in the design of delegated design items.

• Standard Stairs
• Monumental Stairs
• Ladders
• Vanities
• Guardrails
• Signs
• Davits
• Architectural Metals

Shoring

From infrastructure, bridges, and buildings projects to renovation work, construction often requires the need for temporary shoring and support. Our team of construction engineers has experience in all facets of shoring and structural lifting. With a construction mindset and an understanding of best field practices, our team stands out in the industry for developing solutions that are practical, efficient, and cost-effective.

• Bridge Shoring (Erection, Demo, Bearing & Seat Repairs/Replacements)
• Shoring of Excavation (SOE)
• Column Transfers/Removals
• Structural Lifting & Load Transfers
• Hydraulic Jacking
• Shore, Cut & Reconnects (SCR)
• Underpinning
• Masonry Shoring, Needle Beams & Lintels
• Concrete Construction Shoring & Reshoring

Construction Logistics

As projects become more complex and challenging year after year, getting from point A to point Z  is no longer a trivial task – even on the smallest of projects. McLaren can provide engineering support for a multitude of services to ensure projects are built in an efficient, safe, and stable manner across all phases.

• Erection Engineering
• Truss Erection Sequencing
• Sequencing of Construction
• Temporary Stability
• Means & Methods
• Demo Plans (NYC DMO Plans)
• NYC Permitting & Expediting
• Pre-Bid Consulting & Value Engineering

Temporary Structures + Site Safety

Keeping the public safe is the primary tenet of the engineering profession. Our construction division can provide a wide array of services to keep both the general public and site workers safe during the development of any project.

• Site Safety Plans
• Protection Platforms
• Crash Decks
• Debris Netting (Vertical/Horizontal)
• Horizontal Lifelines
