The water engineering achievements of the Inca at Machu Picchu, when defined in technical terms common to modern engineers, demonstrate that the Inca were masterful planners, designers, and constructors. They demonstrated their technical skills through the planning, design, and construction of water supply, fountains, terraces, foundations, walls, and trails. The site of Machu Picchu was a difficult place to build, with high precipitation, steep terrain, and challenging access. Nonetheless, the Inca had the uncanny ability to plan public works and infrastructure in a manner that fit this problematic site and lasted for centuries.

CWSS in Kotamobagu has various problems such as, pipe water network that has not been operated optimally since its completion in 2012. The number of house connections was merely 424 out of 7,600 targeted until 2016. Other problems in Kotamobagu were related to the supply, backwash, insufficient electrical power supply, no water meter, reservoir leakage, and intake pipes leakage in Poyowa and Bilalang. This research aims to find the root of the problem in terms of Clean Water Supply System (CWSS)'s network system, organization, regulation, and management. The research focused on Poyowa Besar's CWSS and Bilalang-1's CWSS networks in Kotamobagu. The research methods included observation, survey, and policy analysis where respondents were required as sources of information. The respondents were from Sia's and Pontodon's CWSS that represented 162 house connections. Additional respondents representing 30 house connections were selected randomly at Poyowa Besar's and Bilalang-1's CWSS for comparison. The results indicated that the community, CWSS managers, and the Central Government support the existence of Kotamobagu CWSS management. The 30 house connections at Poyowa Besar's and Bilalang-1's CWSS have never been served with water, but the respondents positively hope that the matter will be solved in the near future. They were willing to keep waiting for the water network of Kotamobagu's CWSS. The root of the problem in the Poyowa Besar's and Bilalang-1's implementation was due primarily to a network system that was built by the Ministry of Public Works for the Municipal Government of Kotamobaguwas reportedly not in accordance with procurement regulation. There was disagreement between the Ministry of Public Works and Housing (MPWH) and the CWSS managers related to the items that have to be fulfilled for network infrastructure handover.

Singapore's water resources system is a strong illustration of the value of an integrated water resources management in urban enviroments. Today, urban water resources planning and environmental engineering are essential partners in the planning of tomorrow's urban environments - and not just as passive projects unnoticed by the public. In Singapore we can see the specific evolution from the separate development of water catchments and the control of monsoon flooding to the integrated water management strategy as exemplified today in the Marina Barrage. The multi-purpose project boosts Singapore's water supply by creating its first reservoir in the city, helps flood control and enhances the living environment of the city. Marina Barrage presented many interesting challenges in the development of a project whose impact was designed to far transcend the normal functional aspect of a large public works project. This paper will present the many potential public uses that were considered in the planning for the final facility. The motivation is that the 3P (people, public and private) sectors play an important part in sustaining water resources. Instead of designing the Marina Barrage as a conventional functional facility accessible only to operational staff, the project breaks new ground in taking an unconventional design approach. The facility was designed as an open facility to engage and inspire the public to care for water. Features for public education, lifestyle attraction, eating experiences, options for families to relax, play areas for children, attractions for overseas visitors, spaces for dedicated conferences and many more were considered. A multi-functional team of interior designers, landscape architects, researchers, art specialists, lighting specialists, environmentalists, etc was assembled and met continually as the design evolved. These evolving goals had to be integrated into the overall functional characteristics of the barrage. The resulting project is a world-class example of how a project initially conceived for water resources functional purpose can evolve not just into an iconic structure but one whose multi-functional capabilities have attracted huge attention from tourists and the people of Singapore. This is evidenced by more than 250,000 people visiting the facility in its first 6 months of operations, and the many families who spend relaxing time enjoying the various spaces at the Barrage. The evolution of the Marina Barrage in design and operation can act as a lesson for other cities considering similar large flood control or water supply projects. The success of the Marina Barrage's 3P mission indicates how for a relatively little increase in cost these facilities can play a major role in enhancing urban lifestyle in sustainable cities.

Three strong earthquakes occurred and damaged the infrastructures and human settlements at some regions of West Nusa Tenggara Province in July and August 2018. This paper describes the policy and action taken by Ministry of Public Works and Housing (MPWH), Republic of Indonesia, to assist in the rehabilitation and reconstruction, specifically for the housing. The process started from early September 2018 by Civil Servant Candidate from MPWH together with the society. The action was comprised of three phases: socialization, design, and construction. Those phases are discussed in this paper along with their particular obstacles. The most critical phase is deducted. All the resources were gathered from the law applied in Indonesia, the official instruction of implementation, the technical instructions, interviews and volunteers’ point of views. This paper employed qualitative approach through observation, survey, group discussion, and interview to analyze factors that significantly affected the implementation of rehabilitation and reconstruction of houses by referring to the theory. The results of the study suggest that the socialization phase is found to be the most decisive.

AbstractOne of the contract awarding systems in public sector in Poland is the Design & Build system. In this system, a client concludes a contract agreement with only one company, a contractor, in order to carry out both design and construction of works. While deciding on this form of delivery of a public project, the client is obliged to conduct a single proceeding aiming to select the contractor. In this paper, public works contracts awarded in the D&B system in Poland are analysed, whilst attention was put on the contracting modes and assessment criteria. The results are assessed against the experience of other countries and recommended methods for selection of the Design and Build contractor.
