Datum has delivered crucial geotechnical and structural support to €40 million Dublin landmark Ten Molesworth Street.
The former Passport Office and Estate Agents JLL is being transformed into prestigious Grade A Office Building with more than 115,000 sq ft of floor space.
Contractors PJ Hegarty turned to Datum to provide geotechnical and structural monitoring support.
This included noise and vibration monitoring, both were particularly important given the sensitive location of the demolition and then construction project.
Mark Hodgen Operations Manager for Datum said: “We are delighted to be a part of this exciting project for PJ Hegarty in the heart of Dublin. It shows signs of recovery in the construction and property sector within Ireland.”
“As part of our contract we designed and installed suitable instruments which comply with clients & designer’s specification, to give PJ Hegarty 24/7 access to live data from any web-connected device.”
“This project has many complex aspects to deal with. Our sensors and systems are built with robust enclosures that survive extreme & harsh environments such as this.”

As well as concerns over noise and vibration PJ Hegarty had concerns over building & pile displacements including ground water levels at Ten Molesworth Street.
Datum were able to provide real-time data so managers could assess any impact the construction process had on surrounding structures and people.
Hodgen added: “We supplied and installed five Data-loggers supporting six Vibration sensors and four long-term noise sensors. This provided accurate data on impacts from the construction works.
“Also, tilt monitoring was in place with our own wireless TiltMate sensors capturing the stability of adjacent properties. As a backup to the automated systems, we manually monitored surrounding structures with a total station.
“With our wireless systems, we can monitor the entire site and have the information beamed to a central logger removing the requirement for direct cabling. This increases productivity and reduces the amount of on-site time.”
PJ Hegarty’s Contracts Manager John Gavigan said: “With this project being in such a sensitive location, we require reliable, real-time streaming of data.
“Datum Ireland have supplied us a complete and reliable monitoring solution. Having total access to all of the data when we need it and the 24hr IT Helpdesk support demonstrates, that Datum are serious about not only the day to day monitoring but also the after sales support. We are extremely pleased with their service to date.”
Ten Molesworth Street will provide of 180 new workspaces and boast the highest environmental credentials seeking LEED Platinum standard with a BER A3 building energy rating.
