Development of Komatsu's lunar construction equipment began in 2021. The goal is to realize mankind's dream of going to space and building a base on the moon for long-duration stays. However, it is not an easy task to develop lunar construction equipment that can work in the harsh lunar environment as it does on Earth. At present, the lunar construction equipment project team consists of about 10 members, each with knowledge and experience in his or her specialty. We asked the three members, who are trying to overcome various challenges in this project.

Construction delay claims are a common occurrence in projects. When they arise, they need to be evaluated quickly and managed efficiently. However, the whole topic of delay and the various analytical techniques available is one that provokes much debate and con troversy due to the seemingly complex and sometimes conflicting guidance provided on these techniques. The purpose of this book is to serve as a practical guide to the pro cess of delay evaluation and includes an in-depth review of the primary delay analysis methodologies available.

Now the words ‘High Performance Concrete’, ‘Ready Mix Concrete’, ‘Self Compacting Concrete’ are commonly heard not only among the civil engineering community but common people also. With so much of awareness about concrete all around, there is a need that civil engineers should be more aware and informed about concrete technology. They should keep themselves abreast with the latest developments, new technological advances and future prospects. Credits: Indian Railway Institute of Civil Engineering, Pune Mitesh Bhatt, LinkedIn

The cost level is a very important factor in most construction decisions, and its estimates are prepared during the planning, design and construction phases of a construction project. Various types of cost estimates are made in a construction project, from preliminary estimates to detailed estimates. All these estimates are important because they invariably influence the expenditure of major expenses. Estimates made in the early stages of a project are of particular importance, as they influence the most basic decisions related to the construction project. Cost estimation can be defined in various ways. For example, estimation is the assembly of all the costs of the elements of a project, which for an entrepreneur represents the cost that will most likely be incurred for the completion of the project. In another definition, it is a statement-making about the approximate amount of materials, time, and costs to take construction decisions. Cost estimation is also defined as the process of analyzing a specific work and predicting the cost of performing it. The main challenges facing the construction contractor are estimating the cost of building a project, scheduling specific construction activities, and then building the project within the estimated cost and schedule.

This handbook addresses problems facing the engineer when preparing to build, both during the contract bidding phase and after a contract has been concluded. It offers clear guidelines for planning the resources and machinery on site, as well as the safe positioning of roads, cranes, storage and temporary buildings. Site planning activities are presented here in logical sequence, offering an efficient and safe design of the construction site and of the temporary works. The book describes the process of engineering preparation of on-site construction works in all phases of the construction life-cycle, from the design phase - preparing the financial plan and procurement scheme for the owner before tendering the contract; the tendering phase; and after bid completion. A list of procedures is presented for planning the construction site in order to simplify the engineer's work of site and temporary works planning. The Engineer's Manual of Construction Site Planning is for all those involved in the planning of construction sites, construction managers, construction engineers and quantity surveyors, as well as for students in civil engineering and construction.

La NASA a le projet de construire sur la Lune des maisons imprimées en 3D via du béton lunaire conçu à partir d'éclats de roche, de fragments minéraux et de poussière qui se trouvent sur la couche supérieure de la surface de la lune Alors que la Nasa vient de lancer un appel d’offres pour la conception d’un congélateur lunaire, d’autres grands projets sont en cours pour les décennies à venir, et le New York Times s’est intéressé aux habitations prévues pour… 2040. Le grand quotidien américain a interrogé sept scientifiques de la NASA sur le projet de maisons construites avec une imprimante 3D sur la Lune ! Le plan prévoit en effet l’envoi d’une imprimante 3D. Une fois sur place, les astronautes « maçons » utiliseront du béton lunaire constitué d’éclats de roches, de fragments de minéraux et de poussières que l’on trouve sur la couche supérieure de la surface de la lune. Un kilo de matériau envoyé sur la Lune, c’est un million de dollars ! Mais pourquoi utiliser la matière sur place plutôt que de ramener les matériaux à chaque mission ? « Voyager léger est essentiel » rappelle le docteur Patrick Suermann, doyen de l’école d’architecture de la Texas A&M University, qui travaille en étroite collaboration avec la NASA pour développer un système de construction robotisé dans l’espace. Selon lui, chaque kilo supplémentaire transporté par une fusée vers la Lune coûte environ un million de dollars ! « Il n’y a pas de Home Depot (magasin de bricolage) là-haut. Il faut donc soit savoir utiliser ce qui existe, soit envoyer tout ce dont on a besoin » poursuit-il. Sur Terre, l’imprimante 3D construit une maison en 48 heures Le choix s’est donc porté sur ICON, une entreprise de construction basée à Austin, au Texas. Elle utilise déjà des imprimantes 3D pour créer des maisons, dont certaines sont conçus pour résister aux ouragans au Mexique ! L’imprimante peut construire des maisons en 48 heures seulement… Avec ce partenaire, la NASA travaille actuellement à la mise au point d’une simulation du béton lunaire capable de résister à des températures allant jusqu’à 1900 degrés ! Des tests seront effectués sur Terre et dans son Marshall Space Flight Center, situé dans l’Alabama, la Nasa dispose d’une douzaine de chambres d’essai qui soumettent les objets aux mêmes conditions de rayonnement et de vide thermique qu’ils supporteraient hors Terre. En février 2024, ce sera au tour de l’imprimante d’ICON d’y être testé.
