McCormack says clients regularly report a reduction in the construction cycle time because decisions can be made when they are needed, all parties stay on top of the progress and if problems arise, they are noticed more quickly than if the contractor had to wait for everyone to arrive at the jobsite for an update.
"Decision-makers are rarely at the jobsite," adds Allen. "Craftsmen are proficient with the work, but confirmation is needed or when a change is necessary the people who can make the decision are typically somewhere else."
For contractors that implement jobsite cameras a big advantage is being seen in the reduction of travel by the parties involved. But what is probably the biggest return expressed by camera users is their ability to keep everyone up-to-date on the progress of the project through any phase.
Jobsite Camera Solutions
One camera solution that contractors are using on the jobsite are the OxBlue Construction Webcams. These cameras are completely self-contained with controllers and cellular units built in. The way the cameras operate are that once it takes a photo, the image is sent over a cellular network to a tower which transmits over the Internet to a data center, all provided by OxBlue. The photo is then archived and hosted on an OxBlue server and can be accessed via a web interface from any Internet-enabled device.
The benefit of transmitting over a cellular connection is that the need for data connections, onsite IT staff and more wires on the jobsite is eliminated. In addition, cameras using cellular transmissions are able to capture the larger, high-resolution images that provide greater detail over a wide area. The drawback is that these cameras are fixed and if not located on the perimeter of the jobsite would typically have a limited field of view.
An alternative web cam system uses DSL or broadband cable to transmit live images of the jobsite. Because these cameras are directly linked to the Internet, usersc an remotely pan/tilt/zoom the camera to capture different viewing areas.
One solution utilizing new technology is iBEAM Systems, Inc. The iBEAM Handheld camera offers the ability to send live images from anywhere inside the building to decision makers who are not at the job site.
"The iBEAM camera can go anywhere on the jobsite inside or out and send live high-quality images to anyone in the world," says Allen.
The iBEAM Handheld is used by tradesmen on the job to solve problems, by owners taking a daily walkthrough and by architects confirming the quality of the work. Allen uses the analogy of driving nails to represent the effectiveness of the handheld camera. "You can still drive nail with a rock if you had too, taking digital pictures with a cameras is like pounding nails with a rock. A framing hammer works much better but has some limitations kind of like using a web cam that is blind once the walls go up. A nail gun is very efficient and generates direct profit for the user like the wireless camera that allows timely input on critical situations."
The user is able to show someone live close-up images of a specific area of the project and discuss solutions while walking around the area instead of waiting for hours or days to receive input. "It's easy to make things perfect as the material is being installed," says Allen. "It's much more difficult to change after the fact. Most of the time you just have to live with the decision."
The method of viewing live images transmitted by the iBEAM Handheld also differs from other construction cameras. "This application is software-based and not browser-based for security reasons," says Allen. "The video is securely transmitted via the Internet and the viewer needs to use the software in order to see the image stream produced by the iBEAM Handheld camera."
A mobile camera solution like the iBEAM Handheld can be valuable to companies trying to effectively utilize their resources. "Some firms have experts on specific aspects of the construction process," says Allen. "A member of the team can use the handheld and can contact the expert and show him exactly what's going on."
Cameras on the jobsite will not replace the need for visits, but they can reduce the number. If contractors can utilize a camera to have the proper person approve an element of the project or make a decision remotely, then progress continues and everyone can go back to work.
