7 Ways to Improve Surveying Efficiency in the Construction DX Era | How to Compensate for Labor Shortages

As Construction DX spreads across job sites, the way surveying work is carried out is changing dramatically. Traditionally, surveyors would enter the site, carry equipment in teams, take records, return to the office to organize them, and then reflect them in drawings and reports. However, with labor shortages becoming severe, relying on that approach means more and more sites will struggle to operate. In an era of shorter schedules, higher required accuracy, and stricter scrutiny of record consistency, improving surveying efficiency is not merely about reducing effort—it has become a theme that supports site operations themselves. This article clearly explains, from a practical perspective, the concepts of surveying efficiency that practitioners should grasp in the Construction DX era and seven methods that are easy to implement on site.

Why improving surveying efficiency is urgent in the Construction DX era

When people hear Construction DX, many may first think of digitizing drawings and sharing documents. However, the area where real differences appear on site is the initial information acquisition—surveying. If the initial position data, elevations, distances, areas, photos, and point clouds are high quality and ready to be shared immediately, subsequent design checks, construction planning, as-built verification, and progress sharing will flow smoothly. Conversely, if surveying takes a long time, records are dispersed on paper, and are stored in formats only the person in charge can read, all downstream processes will be delayed.

In recent years especially, labor shortages at sites are directly affecting surveying tasks. Work that could once be handled by two- or three-person teams often must now be done by one person. A veteran cannot always accompany junior staff, and it becomes necessary to entrust many on-site decisions to less experienced personnel in a short time. What matters in those situations is not relying on individual intuition or memory, but creating systems that allow anyone to record information at a consistent quality. Improving surveying efficiency in Construction DX is not just about replacing equipment. It must include making on-site data flow in a way that is unambiguous, fast, and easy to reuse.

Moreover, the purposes of surveying have diversified. Beyond traditional batter boards, stakeout, and as-built verification, surveying data are now used for understanding existing structures, pre- and post-development comparisons, earthwork volume checks, recording around buried utilities, and initial disaster response checks. As uses increase, surveying should not be treated as a one-off task but preserved as site data that can be reused multiple times. Therefore, improving surveying efficiency in the Construction DX era is not only about reducing site effort but also about increasing the value of site information.

1. Digitize on-site coordinate acquisition

The first step in improving surveying efficiency is to handle the coordinates acquired on site as digital data from the start. Writing numbers in a paper field notebook and later entering them at the office still remains common at many sites. But this method not only takes time; it causes transcription errors, legibility issues, and omissions. As labor shortages deepen, the impact of a single input mistake leading to rework becomes larger.

The important point in digitizing coordinate acquisition is not merely electronicizing numbers. It is crucial to be able to link, on site, where the acquired point is and what that point means. For example, whether the point is for boundary confirmation, as-built verification, or temporary positioning will affect how it is used later. If you can record point names, attributes, photos, and notes together on site, the time needed for office-side organization is greatly reduced. This allows the data to be saved not as a mere collection of points but as meaningful site information.

Digitalization’s benefits are not limited to shortening task time. If on-site coordinates can be shared as-is, the speed of construction management, design, and client responses also increases. You no longer have to wait for the person in charge to return to the office to get an approximate understanding of the situation, enabling earlier checks and decisions. This effect is especially significant at sites with few staff. Even if only one surveyor is present, preventing other departments from stalling due to delayed information sharing leads to overall optimization.

From a Construction DX viewpoint, digitizing coordinate acquisition does not end as a single improvement. It is the starting point that connects to later drafting, point cloud processing, as-built management, and report generation. Making the initial entry digital makes it easier to automate or semi-automate downstream processes. Reviewing how coordinates are acquired on site and moving away from paper-based operations is the starting point for improving surveying efficiency.

2. Eliminate transcription of surveying records

The less visible burden than the surveying itself is the transcription work. Transcribing field notes, organizing photo file names, re-entering coordinate lists into spreadsheets, and converting them into formats to reflect on drawings—this series of tasks consumes time without taking measurements. At sites with labor shortages, these indirect tasks must be reduced.

Transcription is dangerous not just because it’s tedious. The more times the same information is handled, the more opportunities for mistakes. Typing errors in numbers, missed digits, mismatches between photos and point numbers, and confusion over units are common problems. What’s troublesome is that such errors are hard to spot at the time of input. They often only become apparent when drawings or reports are produced, and then you end up returning to the site for verification. That increases rework rather than improving efficiency.

Therefore, it is important to move toward a workflow where acquired information is completed in a single pass. Aim for a state where point names, photos, positioning results, timestamps, and personnel info entered on site can be used directly as organized data. Improving surveying efficiency means not only shortening on-site work time but also reducing office-side post-processing. In many cases, the reduction in post-processing has a larger overall effect.

For surveyors handling multiple sites, eliminating transcription also reduces mental burden. Long post-site organization in the evening leads to sloppy checks and affects preparation for the next day. When considering surveying efficiency, focus not only on daytime site utilization but also on the time spent on office tasks before and after work. Eliminating transcription alone significantly lightens surveying work.

3. Manage photos and location information together

Photos are a basic form of record on construction sites. However, a large number of photos without information on where they were taken do not become useful later. Conversely, coordinate data without visual context lacks explanatory power. That’s why it is important to manage photos together with location information.

For example, when you want to confirm the as-built condition at a point, coordinates and elevation alone may be insufficient. Details such as surrounding obstructions, positions of temporary structures, pre- and post-construction appearance, and surface conditions are often understood only by looking at photos. If photos are correctly linked to the shooting location or target point, much verification can be done without revisiting the site. This greatly helps client explanations, coordination with subcontractors, and consideration of design changes.

In an era of labor shortages, visiting sites repeatedly is a major cost. Capturing location information and photos together in one visit so they can be reused later is critical. Moreover, this must be done in a way that does not rely on the person’s memory but is understandable to anyone. Construction DX aims not to make those who hold information powerful, but to make information available to whoever needs it at the right time.

Managing photos with location information is also effective for training. Experienced personnel can remotely review records taken by juniors and provide concrete guidance on what was overlooked and where. Location-stamped photos convey site context that is hard to express in words. Improving surveying efficiency is not only about shortening tasks but also about speeding up the sharing of site knowledge. In that sense, reviewing photo management is a highly effective measure.

4. Treat point clouds and drawings under the same reference

As Construction DX advances, opportunities to handle point cloud data on site are increasing. Point clouds are useful for many tasks: capturing existing terrain, comparing pre- and post-construction, confirming structure shapes, and preparing earthwork volume calculations. However, merely acquiring point clouds does not equate to improved efficiency. The key is that point clouds and drawings must be handled under the same reference. If references are misaligned, the data may look overlapping but be unusable in practice.

A common on-site problem is that point clouds were captured well but verifying alignment with drawings takes time. If coordinate systems are ambiguous, elevation references are inconsistent, or site-specific control coordinates mix with design drawing references, interpretations differ by person. In such cases, point clouds become mere viewing data and are not sufficiently leveraged for design comparisons or quantity checks.

To improve surveying efficiency, the coordinates taken on site, positions on drawings, and positions in point clouds must be treated consistently as the same. Then tasks such as pre/post-development difference checks, overlaying with construction plans, and pre-examining planned installation positions become smooth. Once organized, the data is also easier for other personnel to interpret later. Creating a state where data can be used without depending on individuals is the essence of DX.

When point clouds and drawings can be handled under the same reference, the need for site rechecks also decreases. Multiple analyses can be performed in the office based on data acquired once on site. This is extremely meaningful for labor-short sites. Managing many projects with limited staff requires that site data captured once be reused multiple times. Point cloud utilization may seem like a flashy technology, but its true value lies in reducing revisit needs and enabling earlier decisions.

5. Reduce the number of on-site attendances with remote sharing

On construction sites, multiple stakeholders sometimes gather on site to verify survey results. Of course, some matters can only be resolved on site, but not all checks need to be face-to-face. In times of labor shortages, it’s necessary to reconsider confirmation processes that assume in-person attendance. Remote sharing of surveying data is the key.

The value of remote sharing is not just sending files. It lies in conveying surveyed results linked with location information, photos, drawings, and point clouds to stakeholders. When this is possible, the range of judgments that can be made without visiting the site expands significantly. For example, design staff can check overlays of coordinates and drawings, construction managers can judge workability by viewing photos and dimensional sense, and managers can use the data for visualizing progress. Information captured by one person on site can be used simultaneously by multiple people.

The time savings from reduced travel are particularly noteworthy. Travel between sites is a heavy burden in both urban and rural areas. If matters that used to take half a day to verify on site can be judged from pre-shared surveying data, that time can be reallocated to other tasks. As a way to compensate for labor shortages, it’s important to recover time spent on travel and waiting, not just focus on recruitment. Remote sharing is precisely a measure for that.

Remote sharing is also strong in trouble situations. When unexpected conditions arise at a site, if surveying results and current photos are shared immediately, supervisors or other departments can make faster decisions. Content that is hard to convey by phone or verbal explanation can be discussed concretely with location-stamped data. As a result, decision-making burden is less likely to concentrate on a single on-site person. Improving surveying efficiency means not only measuring quickly but accelerating post-measurement decision-making.

6. Prevent dependence on individuals with standardized procedures

No matter how good the equipment or data management methods you introduce, if usage varies by person, efficiency will not take root. If only certain people can operate the systems, the site will stop when they are absent. To compensate for labor shortages, it is essential to move away from operations that depend on individual effort and establish standardized procedures.

Standardization is often mistaken for adding many detailed rules, but the essence is the reverse. It reduces moments of hesitation on site and ensures necessary quality quickly. For example, standardizing pre-measurement check items, point naming conventions, photo-taking methods, conditions requiring re-measurement, and naming rules for sharing will greatly reduce operational variance. The important task is to convert the veteran’s implicit judgment criteria into actions anyone can perform.

Because surveying is influenced by site conditions, complete standardization is difficult. Precisely for that reason, parts that can be standardized should be thoroughly aligned. If personnel no longer struggle with the same issues every time, they can focus on moments that truly require judgment. This is also effective for training juniors. Even inexperienced staff can produce surveying records at a consistent level by following standardized workflows, making supervisor verification easier.

Standardization is also a prerequisite for data utilization. If record formats differ by site, later comparison and aggregation become difficult. Conversely, if point names, attributes, and storage formats are unified, comparing with past projects and cross-site management become easier. In the Construction DX era, improving surveying efficiency needs to be an organizationally reproducible operation, not a one-off improvement. Preventing dependence on individuals is a critical measure against labor shortages.

7. Review equipment configurations so small teams can handle them

When considering surveying efficiency, the review of equipment configuration is often overlooked. Choosing equipment to match traditional methods tends to assume multi-person operation. Situations where heavy equipment must be carried, setup takes time, operation requires role division, or a separate verifier is needed make it difficult to keep operating continuously at labor-short sites.

Going forward, equipment configurations should be designed so small teams can operate them without sacrificing accuracy. More important than high functionality is that equipment is easy to bring to site, quick to set up, and that acquired data can be shared immediately. In other words, you should evaluate based on total time from arrival at site to record sharing, not just individual device performance. Efficiency in Construction DX is not only about the moment of measurement.

Realizing small-team operations also means avoiding an excessive number of devices. Connecting multiple devices, aligning settings, and collecting data separately increases the likelihood of mistakes by less experienced operators. What labor-short sites need is a configuration that one person can easily handle and that is easy to train. As a result, time to proficiency shortens and deployment across multiple sites becomes easier.

Reviewing equipment configurations also improves safety. If surveying finishes in a short time, time spent entering areas with operating heavy machinery or working under traffic controls is reduced. Ways to compensate for labor shortages are not simply plugging staffing gaps. They involve reducing site loads and creating systems that allow small teams to operate without strain. In that sense, creating surveying environments that are easy to operate with few people will become increasingly important on future construction sites.

Tips for successful implementation of surveying efficiency improvements

So far we have introduced seven methods, but how you implement them is crucial to actually achieving results. Attempting to change everything drastically from the start can increase site burden and hinder adoption. To succeed, first identify where the most time is being spent. Depending on whether it is observation time on site, post-site organization, photo management, or sharing with stakeholders, the priority improvements will differ.

Next, evaluate results by time. When introducing a new operation, it may take time to get used to the procedures. However, when comparing total time—including site work, office processing, checking, and possible re-visits—you may find significant reductions. Improving surveying efficiency must be evaluated in terms of the overall workflow, not local optimizations, to see true benefits.

During implementation, prioritize on-site usability. No matter how multifunctional a tool is, if input procedures are complex or confirmation screens are hard to understand, busy sites will stop using it. Especially at labor-short sites, long training periods are impractical, so intuitive operability has great value. Whether field personnel can use a system without hesitation is more important than desktop performance comparisons.

Managerial mindset is also essential. If managers continue to require traditional documents in addition to new digital tools, site burden will not decrease. Digital acquisition must be accepted as-is for evaluation, sharing, and decision-making. Construction DX is not only a site issue; it is a change in how the organization receives information.

Finally, improving surveying efficiency is not a one-time task. Optimal operations vary with site types, objectives, and staff proficiency. That’s why it’s important to start small and continuously improve by identifying where bottlenecks occur. Surveying is at the gateway of construction work. If that gateway becomes faster, more accurate, and easier to share, the overall productivity of the site will surely improve.

Conclusion

Improving surveying efficiency in the Construction DX era is not simply about making tasks faster. It is about building a foundation that keeps sites running without stopping despite labor shortages, maintains quality, and reliably connects acquired information to subsequent processes. Digitizing coordinate acquisition, reducing transcription work, managing photos and location together, aligning point clouds and drawings, remote sharing, standardizing procedures, and reviewing equipment configurations for small-team operations—just focusing on these seven points can greatly change the burden of surveying work.

In particular, the approach of relying solely on surveyors to work harder has limits. You need systems that anyone can use at a consistent level, where on-site data can be used directly for sharing and decision-making, and that reduce re-visits and rework. Creating such an environment contributes to shorter schedules, quality assurance, and junior staff development.

If you want to make on-site surveying possible with fewer people, faster, and easier to reuse, it is important to review both equipment and operations together. LRTK, as a smartphone-mounted GNSS high-precision positioning device, is a compatible option for situations where you want to advance on-site coordinate acquisition, record sharing, and labor-saving in surveying tasks. As a first step in implementing Construction DX on site, those who want to rethink surveying methods should utilize such systems while concretizing efficiency measures tailored to their company.
