Construction Phase Engineering Support

Engineering support for temporary conditions, technical clarification, and execution-stage decisions

Construction activities often introduce structural conditions that differ from those assumed in final design. Temporary instability, erection sequencing, and on-site constraints can create technical risks if not properly addressed.

Rezali provides construction phase engineering consultancy to support contractors, fabricators, and project stakeholders with code-aligned engineering input during execution, while maintaining clear boundaries of responsibility and alignment with the Engineer of Record’s design intent.

This service helps resolve technical uncertainties, manage construction-stage risks, and support safe, efficient project delivery.

  • Construction Phase Engineering Consultancy provides project-specific engineering services during construction to address temporary structural conditions, erection stages, and technical clarifications that arise during execution.

    This service supplements — but does not replace — the work of the Engineer of Record or the contractor’s responsibility for construction means and methods.

  • This service is intended for:

    • General contractors requiring engineering input for temporary works or sequencing

    • Steel erectors and specialty contractors managing erection-stage stability

    • Fabricators needing engineering confirmation of temporary or handling conditions

    • Owners and project managers seeking independent technical support during construction

    • Engineers of Record requiring supplemental construction-phase engineering support

  • Depending on project needs, Rezali may provide:

    • Engineering design of temporary supports and stabilization systems
      (e.g. guy wires, temporary bracing, temporary diaphragms)

    • Erection-stage and construction-sequence assessments
      Including partial completion and non-final load conditions

    • Technical Query (TQ) and RFI engineering support
      Interpretation of design intent, clarification of drawings, and evaluation of proposed alternatives

    • Engineering coordination during construction
      Technical interaction with contractors, fabricators, and the Engineer of Record

    1. Definition of scope, objectives, and responsibility boundaries

    2. Review of design documents, construction sequence, and site constraints

    3. Engineering analysis of temporary or construction-stage conditions

    4. Issuance of engineering sketches, calculations, or written responses

    5. Ongoing technical support as construction progresses

  • Construction-stage engineering activities are governed by the same principles as permanent works:
    clear responsibility, appropriate engineering control, and compliance with applicable codes and standards.

    Rezali provides this service in accordance with:

    • Provincial engineering legislation

    • Applicable building and structural codes

    • Recognized engineering standards and practice

    Engineering documents are issued only where professional responsibility is clearly defined.

  • To maintain clarity and regulatory compliance, this service does not:

    • Assume responsibility for construction means and methods beyond defined engineering scope

    • Replace contractor safety obligations

    • Override the Engineer of Record’s authority unless explicitly agreed

    • Provide site supervision or project management

  • Clients commonly engage this service when:

    • Temporary stability must be demonstrated

    • Construction sequencing creates non-standard structural conditions

    • On-site constraints differ from design assumptions

    • Technical clarification is needed to avoid delays or rework

    • Safe and stable temporary construction conditions

    • Clear, documented engineering decisions

    • Reduced construction delays and technical disputes

    • Alignment between design intent and execution

  • Construction Phase Engineering Consultancy may be delivered under different Engineering Service Levels, depending on the degree of authority and responsibility required:

    • L1 — Review and validation of contractor-proposed temporary works

    • L2 — Engineering supervision of construction-phase solutions

    • L3 / L4 — Rezali-designed temporary works with external drafting or detailing

    • L5 — Full engineering responsibility for temporary systems
