Can a structural designer save your investment schedule?

Date of last update: 14.08.2025

In theory, the schedule is the foundation of a well-managed investment. In practice, it often becomes the first casualty of overly optimistic assumptions, design errors, delays in multi-discipline coordination, and… underestimating the role of the structural designer.

Sounds familiar?

If you’re an investor with experience in large construction projects—industrial, logistics, or commercial buildings—you’ve likely encountered a situation where “the structural design is not ready yet” triggered a cascade of problems. But did it really have to happen?

MYTH: A structural designer is just a documentation provider

There is a common misconception in the industry that the structural designer only comes into play once the architectural concept is complete. The engineer’s role is perceived as “just to calculate and draw.”
This mistake can be costly—not just in terms of money, but more importantly, in terms of time.In reality, a structural designer should be one of the first partners involved in the investment process—especially if the investor wants to retain control over the execution schedule.

REALITY: When the structural engineer saves the schedule

Case Study 1: Logistics Center – 60,000 m²

The general contractor planned a precast reinforced concrete structure to be assembled in four phases. The architectural design featured an irregular column layout with large glass façade sections.

During the review of the assumptions, the structural designer found that:

• the proposed layout required more than a dozen different types of precast elements,
  
• phased assembly would be impossible without temporary supports and costly installation sequences.
  

After redesigning the column and beam layout with prefabrication and assembly logistics in mind:

• the number of precast types was reduced by 60%,
  
• the assembly schedule was shortened by 5 weeks,
  
• the risk of clashes and the need for temporary supports was minimized.
  

This is a textbook example where a well-prepared structural design accelerated not only the design stage but more importantly—the construction itself.

Case Study 2: Office Building in a City Center

This project involved an 8-story building on a highly constrained site, surrounded by operational facilities and heritage-protected structures. The schedule allowed a strictly defined window for reinforced concrete works due to crane availability and logistics limitations.

The structural designer, already engaged during the preparatory phase:

• designed the underground section using a white tank system, with a minimal number of construction joints and concrete pouring stages,
  
• optimized floor slab layout for system formwork.
  

The result? Despite the extremely challenging location, the concrete works were completed 3 weeks ahead of schedule. Moreover, the design was delivered to the contractor fully coordinated with other trades—eliminating the need for last-minute firefighting on-site.

Why does this happen?

Because structure is the decision-making backbone of the entire building. It determines:

• the pace of work,
  
• execution technology,
  
• prefabrication possibilities,
  
• expansion joint layout and construction phasing,
  
• equipment and transport requirements.
  

If the structure is not designed with the schedule in mind—the schedule will not work. And if the designer doesn’t understand how the investor or general contractor plans to build, their documentation becomes an obstacle, not a support.

So where do schedule problems come from?

Based on our experience with dozens of major projects, the most common pain points are:

• Lack of interdisciplinary coordination, where the structural engineer joins the process only after key (often structurally problematic) architectural decisions have been made.
  
• Design disconnected from execution technology—without understanding how the structure will be assembled, transported, or prefabricated.
  
• Delays in delivering construction documents, triggering a domino effect: site downtime, wasted equipment and crew bookings, and the need to amend contracts.
  

Meanwhile, a well-prepared structural team, with a strong leader and experience collaborating with general contractors and investors, can do things differently.

What can an investor do to avoid problems?

An investor who truly wants to safeguard their project schedule cannot treat structural design as a mere box to tick in the project timeline. It must be recognized as a strategic process that influences all subsequent phases—and be addressed accordingly from the start.

In practice, this requires flipping the traditional mindset:
Not “design first, figure out how to build later,” but rather:
“Design so that it can be built—on time and with available resources.”

To achieve this, the structural engineer must be involved early on. Here’s a realistic action plan, based on how successful investors and contractors actually work

Stage 0 – Preparatory Phase / Feasibility Study (−9 to −6 months before building permit)

At the feasibility stage, it’s worth bringing in an experienced structural team—not to design yet, but to provide technical consulting.

This is the moment to:

• decide on the structural system (reinforced concrete, steel, prefab, hybrid),
  
• estimate the structure’s impact on cost and timelines,
  
• assess the potential for phased work and available construction technologies.
  

A structural engineer familiar with real-world execution can identify schedule risks—even before a single drawing is created.

Stage 1 – Concept Design (−6 to −4 months before building permit)

At this point, the architect is usually active. The common mistake? The structural engineer joins only afterward as a “consultant” or subcontractor. Instead, the investor should ensure parallel architectural and structural thinking from the beginning.

The structural designer should:

• co-develop the structural layout in line with functional and logistics assumptions,
  
• work with MEP designers to create clash-free technical spaces,
  
• begin modeling the structure considering assembly phasing, equipment access, prefab transport, etc.
  

This is when decisions are made that directly shape the future construction schedule.

Stage 2 – Construction Design and Tendering (−4 to −2 months before permit / groundworks)

The structural designer now has a solid foundation. If they’ve been involved from the start, the construction design is delivered quickly, coherently, and without surprises from other disciplines.

At this stage, the investor can launch tenders or begin negotiations with the general contractor, having a realistic view of structural costs and timelines.

Importantly, this is also the time to:

• plan prefab elements in line with production timelines,
  
• select formwork and scaffolding systems compatible with phasing,
  
• prepare phased construction documents—for example: foundations first, then reinforced concrete, then steel, etc.

Stage 3 – Execution Design and Construction Start (−2 to 0 months)

A well-managed structural team should now deliver execution documentation in sync with the construction schedule—so-called “just-in-time” design.

In practice, this means not delivering everything at once “to the warehouse,” but providing the right portions of the documentation at the right time, so site crews can continue seamlessly—without waiting, rework, or design changes.

At this phase, the structural engineer becomes an active participant in execution—responding to material changes, contractor decisions, new geotechnical data, etc.—without disrupting key milestones.

The Result?

The investor maintains control over the investment process—instead of reacting to delayed drawings or unforeseen clashes.

Instead of the all-too-familiar scenario:

“We’re still waiting on the design, but we already ordered the precast…”

You get:

“All elements were designed for fabrication at Precast Plant X, with a defined delivery schedule and installation sequence.”

Final Thought: It’s not about whether the structural designer can save your schedule. It’s whether you’ll let them

An investor who involves the structural designer early in the critical phases of the process gains a distinct advantage—not just in time, but in confidence.
It’s not about doing everything faster. It’s about avoiding delays, costly changes, and panic when things slip.

At METIB, this is exactly how we work—not starting from the design, but from the logic of the investment process.
Because structural documentation is not a goal in itself—it’s an execution tool that should operate in sync with your schedule.

We don’t design in isolation from construction reality. We think like engineers—understanding from the very beginning that every design decision has real consequences on-site.

That’s why we see the structural team not as “document producers,” but as partners in managing investment risk—including schedule risk.If you want to truly influence how your project unfolds—start with the right structural design. Or better yet, the right team.
