  • Falsework design

Forest Infrastructure Engineering

StoneCroft has provided engineering services to the forestry industry in British Columbia since 1989, giving us a strong understanding of industry-specific design and regulatory requirements. A core component of our business involves designing and maintaining the extensive network of resource roads, bridges, and culverts, that our forestry sector clients own and operate.

We are recognized experts in designing, constructing, and assessing the log stringer bridges widely utilized in the industry. We also provide resource road and bridge deactivation and reactivation plans, appraisals and valuations of resource infrastructure, and specialist audits for compliance with legal and professional standards.

StoneCroft has designed and constructed over 100 innovative, environmentally sustainable and cost-effective marine and dryland log transfer facilities across coastal BC.  These facilities provide economic access to timber volume in remote, challenging, environmentally sensitive and high public visibility areas.

These facilities have included:

  • Dryland log sort yards
  • Push-off log dumps with fixed and floating skidways
  • “Direct to barge” log transfer facilities
  • Barge ramps
  • Log booming grounds
  • Log bundle dewatering systems
  • Stiff leg derricks
  • A-frame (lift and lower) facilities
  • Barge maintenance shipyards

Heavy Civil & Resource Road Engineering

StoneCroft has been successfully delivering designs for heavy civil projects for over thirty years and can draw on this experience to determine the best and most cost-effective construction method for any project.

Our experience covers steep and technical resource roads, retaining walls, engineered rock cuts, constructed fills, major earthworks, bridge abutments, major culverts, marine facilities, log handling facilities, and other industrial works. Our services cover all project phases, including preliminary planning, cost estimating, conceptual and detailed design, and construction supervision.

We have experience with a wide variety of project and construction types, including:

  • Geosynthetic Reinforced Soil (GRS) retaining walls
  • Log cribbing
  • Gabions
  • Precast concrete blocks
  • Keyed-in riprap/ stacked rock fills
  • Sheet piling
  • Marine infills
  • Arch and box culverts
  • Metal pipe culverts
  • Embedded “stream simulation” fish passage culverts and arches
  • Modified armoured fords
  • Other structure types as required

Surveying, Site Plans, & Construction Survey Control

StoneCroft has extensive experience in topographic surveying, bathymetric surveying, and survey layout and control during construction. We utilize Nikon and Leica total stations (reflectorless and robotic), Real Time Kinematic (RTK) equipment and UAV’s with photogrammetry software.

We utilize our survey data to develop deliverables for our clients including:

  • Site plans
  • As-built drawings
  • Conceptual / General Arrangement designs of bridges and culverts
  • Other deliverables as required

Project Management & Construction Supervision

We provide construction management and supervision of major construction projects.  We can provide detailed construction cost estimation and evaluation of multiple design options, to assist our clients with decision making.  Upon project completion we prepare all required professional assurance statements and record drawings, serving as the Professional Engineer of Record (POR) where required.

In addition to construction management and supervision, StoneCroft also provides hands-on construction services for technical log bridges and log cribbing, along with maintenance and structural repairs for temporary and permanent steel and concrete bridges on resource roads.

Hydrology & Hydrotechnical Engineering

StoneCroft has extensive experience in hydrological assessments and hydrotechnical design for creek and river crossings of all sizes, from small culverts to major bridges. We also have experience assessing channel stability, erosion control, drainage systems, water quality, fish habitat values, and other related hydrotechnical aspects of projects.

Asset Management, Inspection, & Maintenance

StoneCroft has provided inspection and evaluation services to our clients on thousands of structures to ensure ongoing structural, environmental, maintenance and safety requirements are met and risk is minimized. Our inspection services range from routine inspections of culverts to detailed close-proximity structural inspections of major road bridges.

We work with our clients to develop efficient programs for managing their infrastructure assets and prioritizing inspection, maintenance, and repair works. We also regularly directly update our clients’ asset management information technology systems, improving the overall efficiency of the inspection and maintenance process.

Maintenance works that we have designed and supervised the construction of include concrete and steel structural repairs, major scour and foundation rehabilitation, bridge deck replacements, and much more.
