Athough there is much to be said about the actual construction process and installation procedures for concrete pavers, this section will only concentrate on those issues that have a direct bearing on the early stages of the design process. Portion of Harfmann/Day publication
The successful transferral of any vertical load through a segmentally paved area requires the incorporation of three principles. These principles must be utilized when installing open grid as well as solid interlocking pavers. It is also important to note that all three principles in this section are equally important, however, they have been described in a hierarchy that is sensitive to the design process.

Although concrete pavers can be more expensive initially than asphalt or reinforced concrete, it is important to consider the cost relative to the life cycle of the pavement as well. The initial costs for materials and installation and the life cycle costs are considered direct costs and are easily quantifiable. There are however, external costs that are not as easily quantifiable but must be considered when determining pavement options. These costs include environmental impact, road user costs during repairs, integration of other requirements, redesign, pavement rehabilitation and aesthetics. The segmental and precast nature of the concrete paving units capitalize on several of these aspects while reducing lifecycle costs.

The indivual units of interlocking concrete pavements support the concept of a "zipper" which can be undone and then redone in a simple manner. Since the pavers are interlocked and not permanently attached to one another, it is possible to remove several individual units and simply replace them once a repair is made. The final result is undetectable and inexpensive. It is an immediate response to the need to gain access to the surface below or for the repair of damaged areas of the surface.

The foreman of a installation project is in charge of measuring and documenting productivity for the various job functions. In the end of a job the number of hours documented by the foreman are compared to the estimate that was given in the initial job bid. If the number of hours it took to complete the job exceeds the estimate then the job lost money, or was at least not as profitable. It is important for the job foreman to identify steps that can be taken in order to avoid hours that exceed the estimate.
The following is an instructional video that introduces the installation of the ThermaPAVER (Therma-Hexx) ground mount system. ThermaPAVER is the invisible solar collector, that can be used to absorb instead of reflect solar energy. ThermaPAVER can be used to solar hot water, as a means of an efficient snowmelt system and a way to cool interlocking concrete pavers.
The following installation video shows how to use Pave Edge, the original paver edge restraint from Pave Tech, to hold pavers in place. The Pave Edge can easily be hidden using sod or a mulch on the top of the material after it has been installed.
Polymeric sand is a binding substance that is often used to interlock concrete pavers, and the proper application of such material is essential in overall paver maintenance. The following video shows the necessary steps in order to apply polymeric sand to prevent wind/water erosion and weed/insect infiltration.
The following is a short clip that shows how to obtain a curve when laying pavers. One must first overlay the field edge, mark a desired curve using a flexible pipe and pen, and lastly cut the pavers using a saw blade.
The goals of this exercise are to investigate, design and fabricate an interlocking concrete pavement module to assist in understanding structural and aesthetic considerations of connections (edge and unit-to-unit condi- tions) and/or innovative environmental function(s). The exercise’s learning objectives include the following:
• Gain exposure to the technical aspects needed to develop a unique and innovative interlocking concrete pavement module to achieve the desired look, feel and function of a related site design proposal.
• Achieve technical accuracy, environmental and structural function, and the desired aesthetic outcome(s) of a construction detail through real-time fabrication and troubleshooting.
