	For construction sites in urban environments, sometimes a Construction Consolidation Center (CCC) is used to manage the logistics within material deliveries. A CCC is a place close to one or more construction sites, which facilitates the flow of materials going to the site through the supply chain. The CCC is comparable with a warehouse. The construction materials are stored in the CCC until they are needed at the site. Other advantages of a CCC is the opportunity to reduce carbon emission from e.g. traffic, or waste from the construction site and to recycle non-used materials.

	To have a successful CCC, a high amount of the materials must be distributed through the CCC. Otherwise the CCC becomes needless, since there is not a sufficient financial benefit. Another financial aspect is to ensure that the CCC is self-financial. Depending on the size of the CCC, it must serve a certain number of sites to ensure that. The financial aspect is of high importance for owners and managers of the CCC. All in all, they need enough construction sites to be facilitated through them, but also a big enough amount of material.

	When a contractor decides to use a CCC, there are many risks, which must be considered. If one of the other contractors, using the CCC, goes bankrupts the others are effected. Suddenly, there is one less to use the CCC, which could affect the economy. Because of that, the materials for the bankrupted project, are not distributed to the site, and it may affect the whole flow of the CCC (if nothing goes out, nothing goes in). It is practically the same if one project is delayed.		When a contractor decides to use a CCC, there are many risks, which must be considered.

	For the site manager, or the facility manager at the site, some managing skills are required. The construction phase depends very much on this person. At the end of the day, he must know exactly what has been done and what is to be done tomorrow. Furthermore, he should know exactly which materials are needed for the next day. The principle of a CCC depends on daily deliveries, and the contractor must ensure, to have at skilled person coordinating the facility flow. Otherwise, delays will happen, and the usage of the CCC fails.		For the site manager, or the facility manager at the site, some managing skills are required.

	Using CCCs have a lot of advantages in the construction industry. Not only for the construction companies, but also for the suppliers and developers. A CCC could reduce the construction cost and some examples shows improvement of 29% <ref name="slides">http://www.spt.co.uk/wmslib/Liaison_Group_papers/ccc_apr09.pdf</ref>. of the construction time. This is some of the advantages for the developers. For the suppliers it could be mentioned, that there is no (or only less) waiting time at delivery, and the delivery costs can be reduced too, since the suppliers are able to hand-in a lot of materials to the CCC at the same time.

	If a construction project is considered and a CCC is associated, the planning process really benefits from the CCC. This is e.g. due to the low number of vehicles entering the site, which makes the planning of transport logistics easier. It requires some skills of the CCC manager (warehouse manager). He must make sure, that the needed materials are ordered or on the stock at the right time. The easiest way to do that, is to order all the material for the project in the beginning, and store it at the CCC. Then the site manager is able to order the needed materials at any time of the program phase.

	The first thing to evaluate is the size of the project. For small projects it makes no sense, to create a brand new CCC. This is due to the short construction time and to the low amount of materials needed. However, it could be an advantage for small projects, to use an already existing CCC<ref name="WRAP" />. Since they probably have a lot of the necessary material.		The first thing to evaluate is the size of the project. For small projects it makes no sense, to create a brand new CCC.

	The other things to evaluate are e.g. the materials used in the project and the location of the project. Some projects, such as wind turbines and hangers, are often made with big steel components. In that case it will not make any sense to have a CCC, and it is often easier to deliver the components directly to the site.

	If a site is in a location, where the access is sufficient for material vehicles (close to motorway, little traffic around, easy to load/unload etc.), a CCC might not be the right choice<ref name="WRAP" />. Though, it is also important, that the site itself has space enough to store the materials in a safe way.
