The development of advanced composites not only enhances strength, ductility, durability of materials, and endows materials with the multifunctional property, but also reduces the construction cost and promotes civil engineering infrastructure to make sustainable development. In this chapter, several representative advanced composites with abundant research achievements and wide applications are systematically introduced with regard to cementitious composites, fiber-reinforced polymer composites, novel thermally functional composites, and 3D printing composites in terms of their definitions, properties, research progress, and applications in civil engineering infrastructures.

In geodesy, civil engineering and related fields high accuracy coordinate determination is needed, for that reason GNSS technologies plays important role. Transformation from GNSS derived ellipsoidal heights to orthometric or normal heights requires a high accuracy geoid or quasi-geoid model, respectively the accuracy of the currently used Latvian gravimetric quasi-geoid model LV'98 is 6–8 cm. The objective of this work was to calculate an improved quasi-geoid (QGeoid) for Latvia. The computation was performed by applying the DFHRS software. This paper discusses obtained geoid height reference surface, its comparisons to other geoid models, fitting point statistics and quality control based on independent measurements.

The engineering community at large, and the civil engineering community in particular, has the opportunity and arguably the obligation to promote a development agenda that considers not only the economics of development, but also the health of the environment and society at large. In this paper, we contemplate the challenge of sustainable development and its effect on project scale and scope. We discuss the inherent opportunity to drive the "creative destruction" of the development industry, using innovation to exploit inefficiencies in the planning and management of engineering systems to create a range of "future" products and services that challenge existing practice. We review the impact of procurement policy, contract pricing, prescriptive codes, and public policy on innovation. Several examples of innovative design and sustainable development introduced into the planning and management of Canadian civil engineering projects are provided. We assert that the most effective means of promoting the sustainability of built environment and civil infrastructure systems will be through inter- and intra-industry collaboration with the support of public policy-makers.Key words: sustainable development, civil, engineering, infrastructure, innovation, creative destruction, environment, collaboration.
