TENSEGRITY METAMATERIALS: FROM PHOTOPOLYMER NETWORKS TO TUNABLE VIBRATION ISOLATION
This lecture will explore tensegrity metamaterials as a new paradigm for designing lightweight systems with programmable mechanical and dynamic behavior. Enabled by additive manufacturing of photopolymer-based architectures, tensegrity systems offer unprecedented control over geometry, prestress, and material distribution. The talk will show how these design freedoms can be harnessed to tune stiffness, stability, and vibration response. A central theme will be graded tensegrity metamaterials, where spatial variation becomes a powerful tool for enhancing mechanical performance and achieving adaptable vibration isolation. By bridging advanced fabrication, experiments, and numerical modeling, the lecture will outline emerging opportunities for reconfigurable metamaterials and their role in future adaptive and resilient structural systems.

DESIGN OF PHONONIC CRYSTALS FOR VIBRATIONS AND NOISE CONTROL USING THE PARTICLE SWARM OPTIMIZATION
Phononic crystals are heterogeneous metamaterials with a periodic internal architecture specifically designed to control the propagation of elastic waves. A key challenge in this field is the rational design of phononic crystal microstructures to achieve desired dynamic characteristics, such as selective filtering of sound and vibrations in a target frequency range. The speaker will present a novel phononic crystal design methodology based on the particle swarm optimization (PSO) algorithm, which considers the propagation of longitudinal elastic waves in one-dimensional phononic crystals composed of periodically alternating layers of two different materials. The dispersion relation was derived and the corresponding damping coefficient was calculated using the Floquet-Bloch formalism to determine the optimal unit cell size and volume fractions of the constituent materials to effectively suppress the transmission of 50 Hz vibrations and 500 Hz noise.

THE ROLE OF PROJECT MANAGEMENT IN DELIVERING SUSTAINABLE CONSTRUCTION PROJECTS
Sustainability in construction is often associated with innovative materials, low-carbon technologies, and energy-efficient designs. However, the successful delivery of sustainable projects depends not only on technical solutions but also on effective project management practices. Poor planning, delays, rework, inefficient resource utilization, and inadequate coordination can significantly reduce the environmental and economic benefits expected from sustainable construction initiatives.
This lecture will explore how project management functions as a critical enabler of sustainability throughout the project lifecycle. The presentation will discuss the integration of sustainability objectives into project planning, scheduling, risk management, procurement, stakeholder engagement, and performance monitoring processes. Particular attention will be given to the relationship between project delays and sustainability outcomes, highlighting how schedule overruns can increase carbon emissions, material waste, energy consumption, and overall project costs.
The lecture will further examine the growing role of digital technologies, including Building Information Modelling (BIM), project controls systems, and Artificial Intelligence (AI)-based planning tools, in supporting sustainable project delivery. Through practical examples from international construction projects, the presentation will demonstrate how data-driven decision-making can enhance resource efficiency, reduce waste, improve productivity, and strengthen long-term project resilience. By bridging sustainability principles with modern project management approaches, the lecture will provide insights into how the construction industry can move beyond sustainable design and achieve sustainable project delivery in practice.
