There are a lot of things that can get lost in an office when you rearrange everything. Losing a cord may not be that big of a deal, but if you lose a lot of them as you move things around it can really start to add up. It probably saves you more to have a service help you that can keep everything together and organized than it would cost you to have to order a bunch of replacement cords and parts to your equipment that may not be easy to find if you don't rearrange things well.
Any office rearranging that has to be done will be best to schedule a little in advance. This way, you have the ability to pay a little less since it costs more to get someone to come out the next day. You should also take your time to call around since there are probably multiple moving services and you want one that's good at rearranging for you. For those that want to do this themselves, you are going to have to do a little bit of planning and that may take a day so be prepared.
Hiring a mover to help isn't always necessary. You can move things yourself if you are careful. The problem is that there may be so many items that it's easy to lose track of what you were doing or what goes where. It can help to make a list of what is in the office and what comes with it. A printer, for instance, may have a power and computer cable hooked to it. You can take a piece of tape and wrap it around the cords with writing on it that says where it goes or what they are for.
Moving the whole office to a new place can be a big job that you may not have enough people to handle quickly. Let's say that you have to move out because you are paying for a new place and didn't have the money for the one you're working out of for another month. You will need to have everything transferred in a day or two's time, and need everything up and running fast too so you can keep your company working. If you do this yourself it could lose you more money than you save if you are not able to get back to work quickly.
Before letting anyone in to move anything around, secure any files you may have or sensitive equipment people shouldn't have access to. It may not be a problem to let some people move some sensitive items, but you never know what could happen. Customer information like their credit card numbers in a paper file you are moving should be put into your vehicle and transported by you so you know nothing happened to them. Or, you need to get the papers shredded so there's no risk that they will get lost and cost your customers if you no longer need the papers anyways.
Pick out a layout on paper before having things rearranged. For some, it's easier to think of what goes where as they go along, but it will take a long time to do that. Learn how to look at buildings from above and how to draw out things that you want to move like the tops of desks or where doors will be. Get an interior designer to help you come up with a map of what you have now and where everything should be moved when it's all rearranged so you know what it should look like.
Safe moving practices to avoid structural damage need to be followed. Don't drag heavy things just because you don't have any help because that can seriously damage the floors. Try to avoid moving bulky furniture on your own around walls because if you damage them you may have to pay to fix them. It saves you money to do some work by yourself, but you also run the risk of spending more than you save if you are trying to do all of the hard and dangerous rearrangings on your own.
If you have a lot of items and need help with office rearranging, only a team of pros should help. While you may have employees, if everything is heavy you may not want them to get hurt or to damage equipment. You were given the right knowledge here to do what you need to have a comfortable office.
