The method we used predominantly consisted of using a measuring tape, camera, pen and paper.We sketched out a rough floor plan and whilst doing so we were getting dimensions for lengths and widths of walls, stairs, seats, ticket machines, lift etc.
The camera is excellent for documenting a site. Not only can you go back and refer to something you have missed. You can use these images and turn them into textures. Put them onto your computer and save them onto your model to achieve a more realistic effect.
Image of my solidworks model. I Re-created the draft sketch into a dwg drawing so it made it easier to model it up. Although learning how to use the program at the same time as modeling it was a time consuming process.
I also recorded a video of the top level of town hall. I can use this to go back over my model and to check if I have missed things and to add in components that I need to add.
So in conclusion site visits is the best way to document anything. What you gain from it is sketches, photos, videos and audio which capture all the realistic elements: textures, lighting, sound, structures, fixtures, models, colours, interactivity and all other components.
If I had the equipment I would of liked to of use a laser pointed for more accurate measurements. But the measuring tape which we used still did the same job, just took a lot more longer!
Nothing beats pen and paper, cameras and a measuring device at a site visit for documenting. With this combination it allows us to re-create a model that looks perfect to the real thing. And with all the new 3d modelling software out there today. Some people find it hard to tell whether is a photo or a render!
After doing a few site visits over the years. I have also learnt that when taking photos. Take them with a scaled made ruler. Your guaranteed on missing a measurement. But if you have a photo of pretty much everything and in that photo is the scaled ruler, you therefore have all the measurements you need.
You can go back onto the computer and scale things to work out dimensions which you then can continue to work on your model to make it as accurate as possible.
Also with the photos you can put them into photoshop and cut out textures, align them, rotate, scale and make them loop so that they never end. Videos you can cut out the audio and place them into your animation to give a more realistic interactivity.
