Plant facilities of the Inland Steel Company, East Chicago, Indiana, and the East Chicago plant of the Youngstown Sheet and Tube Company, occupy the entire perimeter and adjacent shoreline of Indiana Harbor (Figs. 1, 2, and 3) Major changes in the plants of these companies required revisions in the shoreline and the building of various bulkheads within the harbor and in Lake Michigan outside the harbor breakwater. Small scale hydraulic model studies of the harbor and portions of certain harbor structures were conducted to aid in the solution in the wave action problems arising from the construction programs of the two steel companies. Investigations concerned construction projects recently completed, projects under construction during the course of the model studies, and proposed future plans for plant expansion and harbor development.

Harbour is defined as a place on a body of water that provides protection for the variety of ships from the coastal environmental parameters like waves, wind, tides and currents etc. Breakwaters are typically required for the harbours to provide desired tranquillity and protection for the ships approaching and mooring in the harbour. The harbour layout, the length and alignment of protective breakwater are decided through hydraulic model studies. Flexible rubblemound breakwater is the most commonly used type of breakwater. The hydraulic design of the breakwater structure is evolved through empirical methods and hydraulic model tests. Present methodology and model techniques used to design the cross-sections of rubblemound breakwaters are reviewed and illustrated with a case study of design of breakwaters for fisheries harbour. Suggestions are given to improve and optimize the design. Provision of a wider toe-berm and use of armour units with higher stability, significantly reduces the cost of rubblemound breakwater.

Model Study

Recreational surfing has been studied in Hawaii to develop criteria for the preservation, enhancement and design of surf sites. The criteria will aid in planning compatible uses of the coastal zone. Surfing characteristics and wave transformations were studied in the field and related to ocean bottom features at prime surf sites. A small scale, three dimensional, hydraulic model study was conducted to determine the effect that a given bottom feature had upon the surfing wave. A concept of a multiple-purpose surfing shoal to be compatible with several varied interests in the coastal zone was hypothesized from field, analytic, and model studies.

Background: Including infection preventionists (IPs) in hospital design, construction, and renovation projects is important. According to the Joint Commission, “Infection control oversights during building design or renovations commonly result in regulatory problems, millions lost and even patient deaths.” We evaluated the number of active major construction projects at our 800-bed hospital with 6.0 IP FTEs and the IP time required for oversight. Methods: We reviewed construction records from October 2018 through October 2019. We classified projects as active if any construction occurred during the study period. We describe the types of projects: inpatient, outpatient, non–patient care, and the potential impact to patient health through infection control risk assessments (ICRA). ICRAs were classified as class I (non–patient-care area and minimal construction activity), class II (patients are not likely to be in the area and work is small scale), class III (patient care area and work requires demolition that generates dust), and class IV (any area requiring environmental precautions). We calculated the time spent visiting construction sites and in design meetings. Results: During October 2018–October 2019, there were 51 active construction projects with an average of 15 active sites per week. These sites included a wide range of projects from a new bone marrow transplant unit, labor and delivery expansion and renovation, space conversion to an inpatient unit to a project for multiple air handler replacements. All 51 projects were classified as class III or class IV. We visited, on average, 4 construction sites each week for 30 minutes per site, leaving 11 sites unobserved due to time constraints. We spent an average of 120 minutes weekly, but 450 minutes would have been required to observe all 15 sites. Yearly, the required hours to observe these active construction sites once weekly would be 390 hours. In addition to the observational hours, 124 hours were spent in design meetings alone, not considering the preparation time and follow-up required for these meetings. Conclusions: In a large academic medical center, IPs had time available to visit only a quarter of active projects on an ongoing basis. Increasing dedicated IP time in construction projects is essential to mitigating infection control risks in large hospitals.Funding: NoneDisclosures: None

AbstractLarge and small scale construction projects have waste that cannot be predicted in advance, even the amount cannot be predicted directly, whether it is in large or small amounts. The existence of waste can have a significant impact that can affect construction costs. Waste can have both negative and positive impacts. Good waste management will have a positive impact on the company in terms of cost, even time, and quality, but if the waste that occurs cannot be handled or managed properly it will harm the company in terms of cost, time, and even in terms of quality. In this case, the party that always gets the impact of the waste is the contractor.This study focuses on mitigating the occurrence of waste that is how to minimize it. Thisstudy uses the distribution of questionnaires to the contractor in Surabaya. The results of this study are 5 item indicators on how to minimize the highest ranking. The 5 items are Updating material requirements, Mixing, transporting, and placing concrete at the right time, Increasing the competence and expertise of labor, Provision of good and adequate material/warehouse storage facilities, and accurate material measurement.  Abstrak Proyek konstruksi dalam skala besar maupun kecil, memiliki waste yang tidak dapat diprediksi sebelumnya, bahkan jumlahnya pun tidak dapat diprediksi secara langsung, apakah itu dalam jumlah besar ataupun jumlah yang kecil. Adanya waste dapat memberikan dampak yang signifikan yang dapat mempengaruhi biaya konstruksi. Pada dasarnya waste dapat memberikan dampak negatif maupun positif. Pengelolaan waste yang baik akan memberikan dampak positif bagi perusahaan dalam segi biaya, bahkan waktu dan mutu, namun apabila waste yang terjadi tidak dapat diatasi atau dikelola dengan baik maka akan memberikan dampak negatif bagi perusahaan dalam segi biaya, waktu bahkan dalam hal mutu. Dalam hal ini pihak yang selalu mendapatkan dampak dari adanya waste adalah pihak kontraktorPenelitian ini memfokuskan pada faktor penanggulangan terjadinya waste yaitu cara meminimalisirnya. Penelitian ini menggunakan penyebaran kuisioner kepada pihak kontraktor di Surabaya. Hasil dari penelitian ini adalah 5 item indicator cara meminimalisir yang memiliki ranking tertinggi. 5 item tersebut adalah Updating kebutuhan material, Mencampur, mengangkut dan menempatkan beton pada waktu yang tepat, Meningkatkan kompetensi dan keahlian tenaga kerja, Penyediaan fasilitas penyimpanan material/gudang yang baik dan memadai, dan Pengukuran bahan yang akurat.

The 'Afsluitdijk' is a 32 km enclosure dam which separates the Wadden sea and the Lake IJssel. The dam currently undergoes a major rehabilitation to meet the requirements with regard to water safety. The Dutch Ministry of infrastructure and Water Management (Rijkswaterstaat division) has commissioned Levvel, a consortium of BAM, Van Oord and Rebel, to prepare the design and carry out the reconstruction of the dam including sluices and highway. The project includes reinforcement of the armour layers and wave overtopping reduction. As part of the contract Rijkswaterstaat prescribed the contractor (Levvel) to verify the design with large scale physical model tests (min. 1:3 scale). These tests were carried out in the Delta Flume of Deltares. Prior to the large scale tests, smaller scale tests (1:20) have been carried out to optimize the design with regard to armour stability and wave overtopping. The research described here focuses on the wave overtopping.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/kPga0wVCCIE
