Intelligent Electric Actuators used to provide flood protection in Texas
Intelligent electric IQactuatorswith IB gearboxes on top of the sluice gate, ready to close it in order to prevent flooding.
These sluice gateswere constructed following discussions caused by Hurricane Harvey in 2017,which caused over $125 billion dollars’ worth of damage in the Houston area. During this timemany locations in the 7-county region experienced serious flooding.
Stormwater facilitieswere upgraded throughout the billion dollar golfing community and in other areaswithin the surrounding development. As the area is very flat, possible flooding can be a concern, as stormwater flows into these facilities and down to the sluice gates, connecting to the nearby river. The gates remain open at all times so thatwater can flowinto the river. However, during periods of excessive rainfall and heavy storms,when the river itself poses a flood risk, the actuators close the gates and
seal the development fromthe river. The runoffwater is then pumped away over the top of a nearby levee, allowing it to eventually run back into the river.
The installation of the actuators helps to ensure that the people of this community remain safe fromthe damagewhich could otherwise be caused bywater infiltration into the development.
Rotork Site Serviceswas responsible for commissioning the actuatorswith gearboxes and the start-up, ensuring that all productswere fully operational.
Intelligent electric IQ actuatorswere chosen for this application due to the remote location of the sluice gates,whichwould have prohibited an hydraulic or pneumatic solution. Additionally, the close proximity of an electrical generatormeant that a power supply

was readily available.
Rotork’s IB gearboxes are suitable for use on sluice gates and for themost demanding motorised applications. They’remadewith cast steel andwhen combinedwith the IQ actuator they can reach a torque of up to 44,000 Nm(32,452 lbf.ft).
Sir Robert McAlpine reveals underground highway assets with MGISS Technology
The latest surveying technology fromMobile GIS Services (MGISS) is helping Sir Robert McAlpine (SRM) transformthemanagement of both underground and over ground highway and utility assets. The pioneering work being undertaken on theA19 trunk road will improve operational efficiency and overall safety as part of an assetmapping systemthat can be accessed and updated live and is 3D, Augmented Reality (AR) and BIMready.
Liverpool-basedMGISS isworking alongside
SRMto design and implement newworkflows aswell as converting and updating historical data to populate SRM’sworksmanagement database.
“The highway network is a complex environment. In order tomaintain and operate this essential infrastructure safely and efficientlywe need to understandwhere above and belowground assets are on the network. This allows early conflict managementwith utilities on sitewhen planning newworks or reacting to incidents,” commented Andy Sinclair, ProjectManager for the A19 DBFO contract at Sir Robert McAlpine.
“Using theMGISS developed solution, inspectors and engineers operating on the highway can live access asset information using existingmobile devices,” he continued. “We are also able to share information,which improves our decisionmaking and

collaboration, and the overall efficiency of our inspection routines.”
MGISS originally beganworkingwith SRM when they first introduced the HighStone contractmanagement database from Claremont
Controls.MGISS customised its GeoGrafi App services so that asset condition data, collected in the field usingmobile devices, could be synced to the centralised HighStone database.
The latest collaboration betweenMGISS and SRMhas built on this initial development by converting and updating potentially outdated historical Utility drawings. Planswere traditionally printed out for use in the field, but these have since been converted so they could be uploaded to a GIS dataset. Using ArcGIS Explorer, amobile app that is part of the Esri Geospatial Cloud toolkit, inspectors and engineers can access location-accurate asset data in real time and, using Survey 123 also part of the same environment, report defects and condition reports directly to the hosted system.
