Perspectives to grasp before thinking about the costs of i-Construction

When considering introducing i-Construction, many practitioners’ first concern is ultimately how much it will cost. However, what’s important here is that the perceived cost of i-Construction is not determined solely by the purchase of equipment or software. On site, multiple processes—surveying, design, construction, as-built control, inspection responses, and handing data over for maintenance—must connect before benefits appear. Therefore, judging by a single tool alone often leads to unexpected burdens after introduction.

Especially, many people searching for "iconstruction" are not just curious about a new system; they want to determine whether it will actually work within their company, whether it can be used on site without difficulty, and whether their current staffing can handle it. What becomes important is to view costs not as isolated points but as a surface. In other words, rather than looking only at the purchase cost of a piece of equipment, you need to grasp the whole picture including pre-introduction preparation, on-site operation, data processing, training, and internal rulemaking.

Moreover, the perceived cost of i-Construction varies with company size and the types of sites. Companies that handle many sites under similar conditions can more easily roll out a once-established system, making cost recovery easier. Conversely, when site conditions vary greatly and required deliverables differ by project, the adjustment burden per project tends to be large, so the approach to introduction must change. If you focus solely on minimizing costs, you may actually increase the on-site burden and end up with a system that isn’t used.

When assessing costs, it is also important to separate what appears on estimates from what is less likely to appear. Items that commonly show up in estimates include terminals, measurement devices, processing environments, outsourcing fees, and maintenance contracts. But what actually affects operations are less quantifiable burdens such as staff learning time, rework from data checks, the period of hybrid use of old and new methods, time spent on internal explanations, and coordination with contractors. Overlooking these parts can result in a situation where expected efficiencies don’t materialize and operations become busier in practice.

i-Construction can deliver significant benefits—productivity gains, improved safety, stabilized quality, and better record-keeping—if implemented correctly. However, those benefits are realized only by understanding the breakdown of necessary costs, deciding where to invest, where to hold back, and which parts to roll out in stages. This article organizes the cost breakdown into four parts that you should keep in mind when considering i-Construction, and explains, from a practitioner’s perspective, how to view cost-effectiveness and how to proceed without failing in evaluation.

Breakdown 1 Costs for initial implementation

The first thing to examine is the cost of initial implementation. This is the clearest breakdown and the part most companies compare first. However, what’s easy to overlook is that initial implementation costs are not limited to simply acquiring the main units. In practice, you must consider the full set of items needed to start operations: on-site terminals, measurement devices, peripheral equipment, environments for data checking, communication setup, and storage and transport supplies.

For example, when collecting data on site, you need not only the instruments for measurement itself but also terminals for immediate checks, procedures to securely bring retrieved data back, and protective or fixing devices suited to site conditions. While on paper it may look like one piece of equipment is enough to begin, in reality a lack of surrounding infrastructure often makes it difficult to use. This mismatch leads to underestimation of initial implementation costs.

Also, initial implementation costs vary greatly depending on what you choose to own internally. For tasks you will use continuously, owning equipment in-house increases operational freedom and facilitates accumulation of know-how. On the other hand, owning rarely used or condition-specific items increases maintenance burden. Therefore, when considering initial costs, it’s important not just to decide whether to acquire equipment, but to determine which processes to internalize and which to combine with external resources.

Pay special attention to whether the initial configuration is excessive relative to site objectives. For example, if the goal is to improve as-built control efficiency but you try to simultaneously cover investigation, design coordination, 3D processing, and maintenance handover, the initial burden becomes excessive. As a result, newly introduced systems are often not used effectively and costs precede benefits. Start by narrowing the use case and begin with areas that will reliably produce results to increase acceptance of initial implementation costs.

Furthermore, compatibility with site conditions also affects initial costs. Required configurations differ depending on whether work is mainly outdoors or in confined spaces, whether sunlight conditions are severe, whether there is a lot of movement, or whether communications are stable. Even with the same i-Construction introduction, preparations differ for earthwork-focused sites versus structure-focused sites. If you proceed without clarifying this, you are likely to need additional purchases later, and costs can balloon beyond initial estimates.

To properly assess initial implementation costs, you must concretely articulate what will be done on site, where and by whom, and which processes you want to impact. When trying to grasp costs, people tend to focus only on total amounts, but in practice the reasonableness of initial costs depends on whether the purpose and operational granularity are well organized. Carefully check not only the total on the estimate but also what is and isn’t included—this is the first step to preventing future problems.

Breakdown 2 Costs to establish ongoing operations

A commonly overlooked aspect when considering i-Construction costs is the expense of establishing steady operations. Even if expectations are high right after introduction, results won’t follow unless the system continues to be used on site. In other words, the real importance lies not in simply introducing a system but in making it stick as a standard on-site procedure. For that, you must budget the costs to keep daily operations running from the start.

Operational costs include regular maintenance, updates, incident response, maintaining the usage environment, data storage, ongoing communications, and revising operational rules. These costs are less visible than initial implementation expenses and are often underestimated during the planning stage. However, actual on-site work is not a one-off; continuity is essential. If operations only run smoothly for the first few times but cannot maintain the same quality after six months or a year, the improvement is insufficient.

Operational costs are also necessary to reduce the psychological burden on site staff. When using new methods on site, staff always carry anxieties: Is the collected data correct? Are procedures complete? Will deliverables be acceptable? Who supports us in case of trouble? If these anxieties are left unaddressed, a sentiment that “the old way is more reassuring” can spread, and the new system will eventually fall out of use. Thus, operational costs are not just for maintaining the system but for ensuring the site can continue to use it with confidence.

When considering operational costs, pay attention to the risk of dependence on specific individuals. If only certain staff know how to use the system, it stops functioning when that person is absent. To prevent this, you must share not only operation methods but also on-site decision criteria, data-checking points, and troubleshooting procedures within the company. Preparing these takes time and effort, so in a broad sense they should be included in operational costs.

Also, don’t overlook that a hybrid period with traditional methods is likely at the early stage of introduction. Until the new method is fully established, you may need to use the old method for verification. This temporarily increases workload and can make it feel like “we got busier after introduction.” However, this is not a failure but a natural transition cost until the system takes hold. Proceeding without anticipating this burden can lead internal stakeholders to view the investment as unnecessary.

Although operational costs may look small on paper, they greatly influence practical success. On site, continuing use is the real value. Rather than focusing only on the moment of introduction, imagine whether the same system will be running stably months or years later—this perspective reveals a realistic sense of costs. i-Construction does not produce results simply by being introduced; its true value appears once operations are established.

Breakdown 3 Costs for data creation and linkage

One of the major factors that complicates cost assessment for i-Construction is the cost of data creation and linkage. Information collected on site is not completed there. Only after creating, processing, checking, sharing, converting into submission formats, and handing it over to subsequent processes does the data hold operational value. Therefore, if you only consider measurement and entry costs and do not account for the cost to make data usable, you will not accurately grasp the actual burden.

In many sites, the post-collection organization takes more time than the data acquisition itself because raw data must be adjusted to required accuracy and formats to become deliverables. Moreover, data is not finished once created; stakeholders must align their understanding so the data can be used. Confirmation work, corrections, and re-submissions that arise here are hard to see amid busy on-site work and tend to be omitted from cost estimates.

When considering data-creation costs, it is important to clarify who processes data at which stage. Whether the site staff perform simple checks, another internal team performs processing, or work is outsourced changes the required structure. If you want to expand data utilization but have limited processing personnel, collected data will just accumulate and not lead to the expected efficiencies. In other words, costs for data creation and linkage are not only processing fees but expenses that affect the company’s workflow itself.

Also, when evaluating data-linkage costs, include interactions with submission destinations, clients, and partner companies. If work is completed within the company, you can proceed flexibly, but when data handover to external parties occurs, the adjustment burden to align formats and verification methods increases. This burden is hard to include in estimates but is significant in practice. Especially when you want to utilize site-collected data in subsequent processes, it’s important not only to create data but to hand it over in a state that is easy for the recipient to use.

Note that increasing data volume does not necessarily increase value. Collecting overly dense data or information without a clear use increases storage, organization, verification, and sharing burdens. On site, it’s important to collect data that is necessary and sufficient for its purpose and to have a system that can handle it without strain. To control perceived costs, deciding what not to collect is as important as deciding what to collect.

To properly assess costs for data creation and linkage, you must check the flow before and after deliverables as well as the deliverables themselves: when is data obtained, where is it checked, who processes it, how is it shared, and what is it used for? If this sequence is vague, unseen burdens will accumulate after introduction. The essence of i-Construction is connecting data. Therefore, focus not on the cost of acquiring data but on the cost to make it usable.

Breakdown 4 Costs for training and organizational setup

The cost item most likely to be underestimated—and at the same time the most important—is training and organizational setup. No matter how appropriate the devices and systems you provide are, without prepared people and an organized structure to operate them, site improvements won’t follow. In practice, what matters more than the new method itself is who is responsible for which tasks, what criteria guide decisions, and how people will act when problems occur. Proceeding without organizing these aspects tends to result in unstable operations that rely on the goodwill and grit of individual staff.

When people hear “training costs,” they often imagine operation manuals or workshops. But training for i-Construction is not enough with just that. What you need is not merely to enable staff to operate equipment but to allow them to judge where and when to use it. Understanding which processes will benefit, where to pay attention, how to differentiate from traditional methods, and how to check collected data—only with this understanding does introduction make sense. In other words, training is preparation for operationalization, not just skill acquisition.

Training and organizational setup are not only concerns for on-site staff. You also need to organize roles for managers, office staff, and partner companies. For example, whether the site is responsible only for data collection and another internal department handles organization and checks, or whether everything is completed on site, changes the necessary training content. When this remains unclear, processes without ownership emerge, causing rework and missed checks.

Costs for organizational setup include creating internal rules. Unless you decide file naming conventions, storage locations, verification procedures, approval flows, site-specific recording methods, and reporting routes for anomalies, collected data cannot be fully utilized. While i-Construction gives the impression of digitalizing sites, information management rules actually determine results. Without rules, methods vary by site and operations lack reproducibility.

Also, trying to shorten the necessary training period to save costs can increase overall burden. Everyone is confused at introduction. Without sufficient initial support, ad hoc methods proliferate on site, and later attempts to unify practices create extra work. Spending adequate time on initial training and organizational setup leads to more stable operations in the medium to long term. Training is not something to postpone; it is the foundation for successful introduction.

Because training and organizational setup costs are difficult to quantify, they appear easy to cut. However, cutting them results in a system used only by capable individuals, failing to achieve company-wide productivity gains. If you truly want i-Construction to take hold as operational improvement, you must invest in the people and organization before the tools. When assessing perceived costs, include not only equipment and external services but also the expenses required to get people to use and the organization to operate the system.

How not to misjudge the cost-effectiveness of i-Construction

A common mistake when evaluating i-Construction is trying to compare costs and benefits too simplistically. For example, judging only by how many days of work can be shortened by the introduction overlooks the true value. i-Construction’s benefits are not just time savings. They include reduced quality variation, easier record-keeping, fewer reworks, improved information sharing, and enhanced safety, among other overlapping effects.

Therefore, when assessing cost-effectiveness, you need to look beyond immediate work time to how the entire site workflow changes. For instance, if on-site measurement speeds up but subsequent data organization takes longer, the overall result is not optimized. Conversely, even if on-site tasks take a little longer, if downstream verification and sharing become smoother and overall rework decreases, the benefit can be substantial. What matters is not the efficiency of one process but how the total workload changes.

Also, to avoid misjudging cost-effectiveness, understand the time lag until benefits appear. i-Construction does not produce dramatic changes from the first month. Initially, preparation and training take time and you may feel burdened. But as procedures are organized, staff gain experience, and know-how is shared across sites, benefits accumulate gradually. Expecting early wins without recognizing this lag can cause initiatives to stall.

Furthermore, cost-effectiveness must be evaluated against your company’s specific problems. Whether severe labor shortages, heavy as-built control burdens, frequent re-surveys, or time-consuming record organization is the issue changes which benefits should be prioritized. If you introduce systems without clarifying problems, evaluation criteria become vague and you may end up thinking “it seems useful but there’s no decisive reason.” That is why clarifying your company’s pain points and deciding which issues to invest in before introduction is crucial.

A reproducibility perspective is also necessary when evaluating cost-effectiveness. A single successful site does not justify company-wide investment. Consider whether the system works on other sites, whether the same quality holds when personnel change, and whether it functions in collaboration with partner companies. Only then does the evaluation become meaningful. Systems with high reproducibility yield higher medium- to long-term cost-effectiveness.

Cost-effectiveness of i-Construction cannot be measured by a simple purchasing mindset. You need a broad perspective that includes site productivity, safety, quality, record-keeping, and ease of continuous operation. Grasping costs is important, but more important is clarifying which problems the costs will solve. If that is clear, prioritization and staged approaches become easier to organize.

Ways to proceed to avoid failure in consideration and implementation

To avoid misjudging costs and to introduce i-Construction in a way that works practically, the initial approach is critical. Rather than expanding broadly at once, it is less risky to narrow the target tasks for verification and expand while confirming effects and issues. The goal is not to start small for its own sake but to create a reproducible way of proceeding.

In initial considerations, first identify where the site’s burdens are concentrated. Is surveying taking too long? Is as-built verification difficult? Is report creation heavy? Is record storage and retrieval cumbersome? Once issues are clear, the cost breakdowns to examine become easier to determine. If problem identification is vague, any introduction will lead to fuzzy evaluation and you will focus only on cost.

Next, clearly define the scope of introduction. Trying to change all processes at once increases required preparations and stakeholders, making costs appear excessively large. Start with processes where benefits are easy to see, and proceed while confirming on-site usability, data flows, and internal sharing. Prioritize sustainability over perfection at this stage for better results.

Also, involve on-site staff early in the consideration process. If decisions are made only by management, on-site usability and anxieties tend to remain. Conversely, proceeding solely on site opinions can make company-wide standardization difficult. The important point is to ensure both site staff and management share the same purpose and agree on how to allocate costs. To do so, have a common understanding of why you are introducing the system and what the goals are.

Additionally, decide in advance the criteria for post-introduction evaluation. Determine in advance how much work time changed, whether rework decreased, whether record accuracy stabilized, and how staff workload perception changed. Setting evaluation axes in advance makes cost-effectiveness judgments more practical instead of intuitive. Without this, post-introduction discussions about success or failure become ambiguous and continuation decisions are difficult.

Finally, when considering introduction, also look at future expandability. You don’t need to do everything now, but anticipating which processes you might expand to later changes how you think about initial and operational costs. Whether the initiative ends as a one-off, expands to multiple sites, or strengthens data linkage will determine the configuration and organizational choices. Thinking not only about immediate costs but also future deployment leads to an implementation with less waste.

Summary

When assessing the costs of i-Construction, it is important not to judge solely by surface-level implementation costs. In practice, separating costs into four breakdowns—initial implementation, establishing operations, data creation and linkage, and training and organizational setup—reveals a realistic overall picture. Judging by any single item makes unexpected burdens after introduction more likely.

For practitioners, the key is not whether costs are high or low but whether the investment is appropriate for the company’s issues. If you clarify which processes are burdensome, where improvement is possible, and what is needed for that improvement, evaluating costs becomes easier. Conversely, proceeding with unclear objectives makes even necessary investments appear wasteful.

If you are about to consider i-Construction, start by identifying the most burdensome processes at your sites and organizing how much preparation each cost breakdown requires. Then choose a system that is easy to handle on site and easy to put into operation; this approach leads to higher cost-effectiveness.

If you want to review on-site positioning, location confirmation, or record-keeping, especially consider both initial implementation and operational establishment within this cost structure. For example, an iPhone-mounted GNSS high-precision positioning device like LRTK is an option worth considering when aiming for a configuration that is easy to handle on site. Rather than starting with a large organizational change, begin where on-site users can handle it without strain and where location information can be integrated into daily work. Proceed step by step, ensuring costs are viewed correctly and the system becomes established on site—this is the shortest route to results.
