Construction-Engineering Interface

The EPCM contractor s engineering department (ED) will have been responsible for designing the plant and for the technical input to purchase orders and construction contracts. These tasks will not have been fully completed at the time the site is opened. The ED will now assume the additional responsibility of providing the EPCM contractor s site team with the following inputs

Again, just as was mentioned in 2.5 above, in view of the Modelling emphasis this Evaluation feedback is not directly relevant however, in tenns of feedback to the organisation in a broader sense (see figure 4.3) it will be obvious that both process designers, interface construction engineers, and managers at several levels of the plant, and the company could clearly benefit from the analysis as presented above. 

The following is a brief review of some of the more important construction management topics, with special emphasis on the engineering interface and the peculiarities of process plant work. 

The importance of surface characterization in molecular architecture chemistry and engineering is obvious. Solid surfaces are becoming essential building blocks for constructing molecular architectures, as demonstrated in self-assembled monolayer formation [6] and alternate layer-by-layer adsorption [7]. Surface-induced structuring of liqnids is also well-known [8,9], which has implications for micro- and nano-technologies (i.e., liqnid crystal displays and micromachines). The virtue of the force measurement has been demonstrated, for example, in our report on novel molecular architectures (alcohol clusters) at solid-liquid interfaces [10]. 

Functional Design Tailored design evolving. Performance criteria clear, system construction evolving, i.e., specific components not known. System relationships/interfaces are known. Engineering line diagrams available. 

ANL has constructed a tribology test rig that operates at the speed and interface pressure of the TIVM compressor/expander vanes at full power. This test rig is depicted in Figure 2. Initial dry friction and wear tests with stainless steel and low friction engineered polymer samples provided by Mechanology have indicated an acceptable friction coefficient at the TIVM operating conditions and wear rate consistent with the lifetime requirement. Additional tests are being conducted with high humidity and different material combinations.
