Dublin-based engineering contractor ClearTech has won 50% more jobs with enhanced estimation efficiency from BIM software
ClearTech Engineered solutions is a Dublin-based specialist engineering contractor that designs and installs post-tensioning for bridges, buildings, roads and other civil engineering projects.
Post-tensioned structures require less concrete and reinforcement, which has a smaller environmental impact than traditional or pre-tensioned concrete. And as demand for these services rose, ClearTech had more RFQs than it could answer.
As a result, ClearTech started using Bluebeam Revu to increase the speed and precision of its project estimations. This became the digital centre for ClearTech’s practices, encompassing estimations, design and revisions, QA/QC and document management.
Digitisation has saved ClearTech thousands of euros by cutting the cost of paper printing for design comparisons and revisions. Additionally, use of the overlay tools resulted in faster annotation methods and reduced work hours per project.
CEO Feargal Cleary started ClearTech in 2010, in the depths of a major industry downturn
Cleary knew that the traditional operations and models in design and construction would soon give way to technology-driven and environmentally sustainable models that would require leaner operations.
While large companies cut budgets to steady their businesses, Cleary aimed to build something more flexible: the first concrete post-tensioning service in Ireland.
Post-tensioning is the process of casting concrete with steel cables in ducts, then tensioning the cables to compress the cured concrete. The resulting slab has the compressed strength of concrete and the tensile strength of steel.
“Sustainability – it’s a big focus for ClearTech,” Cleary said.
“So, what we do is we reduce the concrete depth, reduce the reinforcement and this gives the client a sustainable solution over the lifetime of their building.”
ClearTech’s post-tensioning process has benefits for the environment and the company’s profits – it uses less concrete and earns tax incentives and rebates by lowering environmental impact.
Digitalising quantity estimation
In 2018, ClearTech’s reputation led to more tender estimation requests than ever.
Everyone was using PDFs for releasing design information but there was no easy way to quantify material measurements digitally.
Furthermore, the ClearTech team was still using A3 and A1 prints, often losing half a day waiting for designs from the printers, only to spend hours marking and measuring drawings by hand. This time-intensive process was also prone to errors, resulting in inaccurate estimations and rework. ClearTech needed to speed up its estimation process.
The team at Powergreen Software introduced ClearTech to Bluebeam Revu and trained the team on doing digital estimations with its automatic measurements and exportable metadata.
The results were immediate: the printing budget was cut by two-thirds, saving thousands of euros. And since proposals weren’t trapped in administration, there was more time to look at new projects.
Expanding use of technology
The overlay tool in Revu was soon discovered and put into constant use by ClearTech engineers in the design revision process. Designs change rapidly; tracking those changes and keeping every stakeholder aligned can be challenging because a single project might have hundreds of different designs. ClearTech engineers use overlay tools to compare plans and quickly spot design differences.
Leticia Siqueira, a ClearTech structural engineer, uses the overlay tool to track the change that happens on site and at the construction stage: “So, when new revisions come in, I can easily see the difference and work on them straight away.”
“We used to print the two drawings – the newest one and the previous version – and look at them,” added Thiago Tamm, another ClearTech structural engineer.
“It would take well over half a day to go through these drawings to compare changes. But, with the overlay tool, you can just do it now in fewer than 25 minutes and you’re done with comparing.”
ClearTech also uses Revu to set key performance indicators (KPIs) for engineers on site to track how long each task requires, as well as to input that data into custom column sets in Revu. By analysing this information, ClearTech can more accurately estimate the cost of labour, concrete and steel in subsequent budgets.
Using the overlay tools, engineers can also share revisions almost instantly, creating a trustworthy and up-to-date single source of truth for all parties, increasing transparency between stakeholders.
Communication between the office, jobsite and contractors is also faster, simpler and more precise. The benefit comes in the form of cost savings by minimising delays and mitigating risks for rework and injuries, as fewer hours are necessary to complete a job.
“We have the cloud-based system so that we can communicate with the guys on site,” Tamm said.
“We are always making sure that the newest drawings are in there for them to follow the current revision.”
Siqueira added that Revu helps her track “any change that happened on site and to communicate in an easier way, in a personal way as well, with all our employees and other contractors.
Every project’s completion adds data to the company’s business intelligence, so ClearTech can continually refine and improve its operations and estimates, and reduce waste in both material and wages – all of which fits the company’s larger lean approach.
Cleary said that by using customised columns “we’re able to get accurate understanding of what we’re using on site, what’s being used, what’s required and what we need to order. We use that insight in the office to create our orders to look ahead”.
Because Revu is at the centre of ClearTech’s data operations, it’s also used for the company’s QA/QC processes – partially for its own meticulous record-keeping but also in fulfilment of an Irish legal requirement, the Building Control Amendment Regulations (BCAR). The regulation requires tracking materials used in building and renovations, and is designed to increase transparency between builders, owners and residents.
“It’s important that, through the BCAR, we have an accurate understanding of every part of the systems that we’re putting into the concrete,” Cleary said.
There’s also the advantage of better communication with partners and clients.
“The other companies that we work with, they use Bluebeam as well,” Tamm said.
“And we communicate using the same software so we have more concise and accurate comments and reviews on the drawings.”
Cutting waste, saving money, expanding frontiers
Since ClearTech started using Revu for its estimations, it has cut waste, improved record-keeping and communication and increased transparency among stakeholders.
The company has won an additional 50% of projects, thanks to its much-improved estimation and communication process. It has also gone on to complete work for clients such as Salesforce, Facebook and Amazon.
Still, the most important difference might be cultural, as the entire ClearTech team has used the technology to improve its performance, raising the company’s ambitions.
ClearTech has since taken its business international, completing projects in Saudi Arabia, Vietnam, the Philippines, Malaysia and Indonesia. Growing the business at home, to be sure, has also become a bigger priority.
“We want to be a leading light in the industry,” Cleary said, “and we’re pushing the likes of Bluebeam to demonstrate there is an opportunity for innovation in the industry here in Ireland.”
Today, ClearTech is faster, leaner and more successful than ever. It has become the company that Cleary envisioned when he first started it 10 years ago.
“What we’re seeing now is that we can think ahead and we can look forward and that there’s a consistency of projects that are coming in now that we didn’t have before,” Cleary said. “And that’s what we are seeing now that we’ve started to use Bluebeam.”
