Seequent’s Singapore event on digital innovation in ground engineering

On 24th May 2018, leaders from Singapore’s civil and environmental engineering industries gathered together at the New Zealand High Commission to join the conversation about digital innovation in ground engineering.

Speakers Daniel Wallace – Seequent, Michelle Lee – Penta Ocean, and Edward Armstrong – Penta Ocean

With expansive views across the Singapore skyline, invited guests and speakers came together to network, discuss and engage. The presentations were spearheaded by Seequent’s General Manager for Civil and Environmental, Daniel Wallace, who shared Seequent’s vision of the future. Daniel explained how Leapfrog Works, a revolutionary solution to understanding, visualising and communicating ground conditions, is the only 3D sub-surface modelling solution specifically designed for the engineering sector and as such addresses many challenges costing the industry time and money.

To showcase Leapfrog Works in action, special invited guests from Penta-Ocean Construction Company Ltd, explained how they are using Leapfrog Works to better understand ground conditions in Singapore.  Speakers Michelle Lee, BIM Manager and Edward Armstrong, Senior Engineering Geologist, took the audience through their VDC (Virtual Design & Construction) roadmap and explained how Leapfrog Works enabled them to reduce risk both financially and in Health and Safety, ultimately advancing how they complete geological modelling.

“We were delighted that Penta-Ocean accepted our invitation to showcase their recent Singaporean engineering project,” says Daniel Wallace. “The event was a great success. It was a real honour to meet with industry leaders, some for the first time and others we know well, and to be able to also demonstrate Leapfrog Works hands-on in the event’s Discovery Zone.”

Performing a Jack-knife-Style Analysis Using Leapfrog EDGE

One simple yet effective method for testing estimation sensitivity is to run a jack-knife analysis, wherein a sample or set of samples is intentionally removed from a dataset, an estimation is performed in the location of the missing samples, and the estimated result is compared back to the samples. The tools and workflow built into Leapfrog EDGE make this a simple operation to perform at a block level by comparing the results of two different estimations.

1. Create A Standard Estimator

The first step to running a jack-knife is to create an estimator using all data required. For this example I will use the LMS1 domain from the Leda training dataset, and will be estimating the Zn grades within that volume.

When time is your enemy, you need your software on your side

By Seequent Product Manager PJ Hollenbeck

All projects have their challenges, but those with a fast turnaround have a special set of problems and pressures.

A succession of accelerated construction deadlines may call for rapid iteration of geological models to meet the shrinking timelines. You might need to develop multiple hypotheses from the data you have, often in a very short space of time.

That would be ok if the software you were using was built from the ground-up specifically with geologic modelling in mind, but often it isn’t. Instead, you may be relying on tools co-opted from another industry or discipline and not intended for the ‘artform’ of geological modelling. Not only will that tend to make the initial modeling process slow and difficult, but when new data comes in – as it frequently will – it could take days, even weeks to update the model. Meanwhile, the project is already underway and costing money.

Collaboration is easier when you can work directly with a range of data sources

By Seequent Product Manager, Pat McLarin

Collaboration is key in the success of any ground engineering or environmental services project.

However, while the teams involved may be keen to share their data, ideas and detailed designs with others on the site, the software they are using may have different ideas.

Human collaboration can be tripped up by the difficulty of getting different data formats to work together. That shouldn’t be the case, though it’s not hard to see why it happens.

Every stage of a project’s workflow requires its own software package. Ground investigations, topological surveys, GIS, engineering designs, geological and geotechnical models will all have their own variations as each specialist area has its own particular outcome to achieve. That will shape the data format, leading, inevitably, to many of those formats being incompatible.

This can make progressing from step to step difficult, costly and frustrating. Technical experts can waste valuable time manipulating data – sometimes manually, sometimes through multiple software packages – and risk losing key information along the way.

Mastering new tools for today’s resource estimation challenges

SRK’s Peter Gleeson talks about Leapfrog EDGE, our new resource estimation solution that’s quick to master and saves time without compromising on quality.

Peter Gleeson, an expert with thirty years’ experience in resource estimation and mining geology tells us what he likes about Leapfrog EDGE, where he sees the future of resource estimation heading and why tools like EDGE will become so essential.

 

 

How has resource estimation or geostatistics changed over the last 10 years?

It’s become a lot more sophisticated. The market has moved from just using general mining packages to using niche packages that specialise in a specific area. Leapfrog EDGE combines many of the tools from these specialist packages into an all round estimation package. They have learnt from the mistakes of others and listened to what the resource geologists need. Examples of this include automatic Swath validation plots, automatic Boundary Analysis plots and improved ways of interpreting variography.

How do you think it will change over the next 10 years?

The industry needs more dynamic estimation models. A single static model for the life of mine is no longer good enough. Management want to test risk in a project or estimate. Only having one model that takes months to update is a barrier to this process. Leapfrog EDGE offers the opportunity to perform multiple realisations of an estimate in a relatively short time frame compared to other software.

What is one part of the resource estimation process that is often overlooked?

The geology. People put a lot of effort into geostatistics and they make fundamental mistakes as they don’t understand the geology. Combining the power of Leapfrog Geo with a fully integrated estimation workflow means the practitioner can give stronger emphasis to providing a robust geological model to underpin the estimate. Geostatistics will not save you if your geological domains are incorrect. Hence the acronym EDGE (Estimation, Domaining and Geostatistical Evaluation), with the emphasis on domaining. Working directly with Leapfrog Geo means resource domain models can often be updated in minutes as new data becomes available rather than days or weeks. Despite the improvements in efficiency of these new tools the fundamental input and understanding should be through good geology.
