A private house in Ramat Hasharon A second opinion for the project of a house on spillway soil that resulted in savings of hundreds of thousands of shekels in the execution method. The challenge: The instructions given by the previous consultant included deep foundation. The soil layers on the site were layers of loose sand that did not allow dry drilling and required drilling using the bentonite or CFA methods, that made the execution very expensive. The solution: Changing the execution method for shallow foundation, choosing between the option of a barge (raft) or individual foundations (plates).

Soil consultant A soil engineering consultant protects you and your interests vis-a-vis the professionals who are going to build your house: the consultant analyzes the nature of the soil and recommends how to establish the infrastructure to prevent drifting or subsidence of the building in the future. There is no legal obligation to hire the services of a soil and foundation consultant, and since the building engineer (construction engineer) should provide a response in this area as well, it is certainly possible, and even recommended, to hire such consulting services separately. To understand better, we have put together a short guide for you: How to choose a land consultant . Why should you hire Yuger services as land consultants? Eng. Yuger, born in 1950, graduated from the New York Polytechnic Institute with a B.Sc (1976) in civil engineering and an M.Sc (1978) in soil engineering. and over 30 years of experience in the field of soil foundation - as a lecturer, a member of national standardization committees and of course in hundreds of consulting and accompaniment projects in the private, industrial and public sectors and accompanied by a team of soil engineers, civil engineers and geologists and additional operational staff. The content of the land and foundation consulting service will be a land survey, an examination of the environment, initial advice on the nature and depth of the foundations for the foundation, as well as actual accompaniment of the works in the field. When choosing a land consultant, it is recommended to pay attention to - certified land consultant - ask to see the consent certificates. Academic background and in particular mastery of Israeli and international regulations, laws and standards. Seniority and proven professional experience including references. Specific experience for the type of infrastructure planned. Legal and technical support.

Value engineering - reducing the cost of a construction project Value engineering in the field of construction, allows savings in the costs of the project and on the basis of studying and examining its various engineering aspects and formulating recommendations for changes in planning and implementation while maintaining the quality of the final product. As a provider of soil consultant services, at Moti Yuger we make sure to incorporate in our services the professional aspect of "value engineering" which allows us to control existing land reports, construction plans and projects in the execution or finalization processes. Our professionalism has enabled us in the past and during the examination of plans of private projects of building houses as well as business-commercial projects to present alternatives for saving significant amounts that made it possible to get started with an execution budget that is tens of percent less. "Value engineering examines ways to improve the function of the product, and to make it cheaper by reducing the raw material, reducing the accuracy requirements and streamlining processes" (Gideon Halevi) and this from a professional engineering approach based on proven academic tools as well as the many years of experience of the Moti-Yuger Engineering company . We specialize in value engineering services for reducing construction project costs under commitment. Value engineering, what is it? The field of value engineering is institutionalized and includes several steps: preparation Research and data collection Analysis Developing alternatives Evaluation of alternatives Forming conclusions Introducing a recommended alternative Monitoring and in further detail and based on standardization such as the international ISO 15686. Information gathering What is going to be done? Who is the performer? What is the required result? What must not happen? Measurement What is the method of measuring and evaluating the alternatives? What are the different approaches to providing the alternatives? What are the alternatives that will allow the presentation of a similar result as required? Analysis What is required to be done? How much does it cost? Are there alternative ways to achieve the goal and the required product? Assessment Which of the alternatives is preferred and will yield the best result? Developing alternatives What are the consequences? What are the costs? What is the performance? Presenting alternatives Presenting alternative solutions to the client, recommending the best alternative and tools for making a decision. If you would like to learn more about the academic-professional background of the value engineering approach, you can find a lot of material in volume-2 of the book "Engineering Design" by Gideon Halevi published by the Open University at the link here. Do we perform Value Engineering? Definitely yes. The professional workforce at Moti Yuger Eng allows us to carry out cost reduction processes in projects and by using a value engineering approach. In the past, we have already carried out a number of complex construction cost reduction projects that managed to significantly reduce the final construction cost for the client - whether in private construction or in large-scale business construction. However, it is important to note that at Moti Yuger Eng., the focus is not only on reducing costs through material savings, but is mainly based on a thorough examination of the construction methods and finding efficient, safer and cheaper alternatives.

Using rock bolts - to support the wall of a mountain Making mortar for the rock bolts that support the side of the mountain, in which "Yuger Engineers" served as the soil consultant F rom the beginning of a project of the company Natura and for 20 two-family units and under the supervision of "Or Engel - Bedek Bait B nya".

Soil drilling An experimental soil drilling project for sampling (also known as trial drilling), in the process of formulating the soil report before the construction project, is a central and essential component that cannot be done without. Soil drilling - why? As part of the soil survey, samples are taken in the field through a series of drillings aimed at collecting soil samples at the designated locations and depths b ased on historical mapping of the site. The purpose of testing the soil as part of the drilling is to determine stability , the type and quality of the soil and allow the engineer and constructor to submit recommendations for the infrastructure of the future construction project. The professi onality and thoroughness of the various stages in the drilling and sampling process has a significant impact on the ability to analyze and formulate recommendations later and therefore on the nature of the planned construction project. The considerations for the experimental soil drilling contractor are based on the instructions of the soil consultant and the historical mapping as well as an examination of the actual sampling site and considerations of accessibility, coverage and clarity of the sampling products. Types of soil drilling for sampling - methods and considerations There are several methods performing soil drilling for sampling and the tools they use accordingly. The main considerations, in choosing the drilling method and tool, are: 1. Accessibility of the sampling site (restricted access, electricity/water infrastructure, closed building, etc.). 2. The depth and diameter of the drilling, according to the planned construction. 3. The type of soil. 4. The purpose of the project (private, commercial, public or other construction). For example, for private construction the accepted drilling depth is about 12 meters, while for a building about 24 meters. Therefore, according to the afore mentioned limitations, drilling is possible with the following methods: 1. Mechanical drilling tower - deep soil drilling, only on a site with high accessibility. 2. A mechanical drill on a truck - intended for great depths and difficult soil types. 3. A mechanical drill on a tractor with the ability to tilt - suitable for sites with limited accessibility, but not for deep drilling. 4. Hydraulic hand drill (mechanical) - limited in medium depth and diameter of operation, but suitable for sites with limited access even for a tractor drill. 5. Manual drill - limited in the depth and diameter of the operation and according to the physical ability of the driller, but suitable for sites with limited access even for a tractor drill. Types of drilling: 1. Core drilling (HQ wireline rock): designed for rocky soil. 2. Spiral drilling (hamster): designed for dry or sandy soil. 3. DCP drilling: soil density test designed for mapping the location of the layers, thickness and determination of soil strength (more on DCP drilling, here). 4. SPT drilling: drilling to evaluate the density of the soil, using a special tubular drill (more on SPT drilling, here ). Of course, the more drillings are carried out, the richer information is obtained and which enables a more accurate and reliable decision to be made. However, the land consultant together with the constructor knew how to optimize the layout of the drillings according to professional considerations and such as those detailed above. Selection of soil drilling services There is a large variety of soil drilling contractors on the market, so it is important to examine several alternatives of service, methods and price. Of course, you should not hire the services of a contractor who has not received recommendations and the products of his work have not been tested and accepted by the soil consultant you have chosen to contract with. In certain cases, the soil consultant himself will recommend to you the services of a drilling contractor that he works with on an ongoing basis and therefore trusts the professionalism of his work products - which, as mentioned, are essential for producing a professional land report. However, the soil consultant should be required to specify the requirements and products from the soil drilling and to allow a market survey between different contractors.

The bridge over Boho river The project of the bridge over Boho river, in which Eng. M. Yuger served as a soil consultant on behalf of the contractor Sollel-Bona, was intended for the railway line from Ashkelon to Be'er Sheva and in accordance with the constraints of preserving the environment and the complex infrastructure for a railway bridge, and was a unique project in Israel. The bridge is located above Boho river , west of the city of Netivot, an environmentally sensitive area and for the purpose of building the bridge, it was necessary to carry out a strict and gentle process in regards to the preservation of nature. The project The planning began in November 2010 and the execution began in February 2011 and ended in October 2012 - the executing contractor was "Sollel Bona" and the land consultant on behalf of the contractor: Eng. Moti Yu ger. The bridge includes eight equal spans 32.5 meters long, 12 meters wide and 260 meters long. The bridge spans have a hollow circular section with a diameter of 4 meters and reaches a height of about 20 meters. The upper structure of the bridge consists of two massive prefabricated beams 2.2 m high, weighing about 200 tons each, cast on site and hoisted on top of the bridge girders. After placing the beams, a 30 cm thick bearing plate is cast. The bridge is a continuous bridge with seams in the end commissioners and two internal commissioners, where some of the commissioners are harnessed to the lower structure. In the end commissioners and some of the internal commissioners, special EKH-type authorizations were assembled. These braces prevent displacements across the bridge and thereby also share the unharnessed commissioners with the journey in receiving the horizontal forces obtained from loads, such as centrifugal loads, wind loads and earthquakes. In the longitudinal direction of the bridge, the supports allow the movements in order not to receive large forces due to loads such as temperature, shrinkage and creep. The documents were designed to receive horizontal forces of up to 200 tons. A detailed interaction calculation (bridge rail) was made for the bridge using MIDAS CIVIL software in accordance with the European standard EN 1992-2. Quality control during execution During the casting of the prefabricated beams, a discrepancy was opened by the contractor's quality control regarding the strength of the concrete that came from one of the mixers for casting the beam. Two separate tests were conducted by two different test institutes. According to the results of Institute No. 1, a compressive strength was obtained at the age of 28 days of 66 MPa compared to 5.30 MPa according to the results of the second Institute. At this point it was decided to wait for the concrete strength results at the age of 50 days to verify the results. Upon receiving results after 50 days, it was decided to conduct an in-depth examination to clarify the issue. The actions taken: The instruction to remove cylinders in suspicious places in order to be sure that there is concrete of low strength in a certain area of the beam. For this purpose, a typical beam casting was followed in order to discover the location of the defective mixer. A meeting with the concrete technologist to clarify the issue. Schmidt hammer test, which is a test that allows you to get an idea about the differences in the density of the concrete in different areas. The test does not give the strength of the concrete but only indicates changes in its uniformity. As mentioned, in order to give instructions for removing cylinders to test the strength of the hardened concrete in the places where the low-strength concrete was poured, a basic sketch was made, based on the order of casting the beam, for the location where the weak concrete is suspected. The execution of this sketch was possible only thanks to the execution engineer who documented in an orderly manner the order and method of casting that were actually carried out. The results of the rolls obtained definitely showed a decrease in the strength of the concrete: Rolls No. 1,2,3 in the area of the weak concrete showed the strength of the concrete lower than planned - Rolls No. 4,5,6 in the normal area showed the strength of the concrete as planned. At this stage, an in-depth examination was made into the way the problem was handled and after additional tests, consultations with the client of the work and the project manager, it was decided to reinforce the beam in order to qualify it for full function as planned. Despite many pressures to approve the beam because there was a laboratory test that proved that the strength of the concrete is 60 and the concrete technologist's claim that the concrete that arrived at the site is definitely of the 60 type, it was decided to carry out an in-depth examination of the issue in order to eliminate the smallest possibility that there is concrete with a lower strength than planned. It should be noted that the inspection could not have been done without full cooperation on the part of the contractor and on behalf of the quality control on the part of the contractor. Thanks to the in-depth inspection that was done, a concrete beam with a lower strength than planned was discovered and corrective measures were taken.

Development of neighborhoods in Beit Shemesh Development of several neighborhoods in Beit Shemesh on complex and problematic soil The challenge: Development of the "glasses neighborhood" and neighborhoods D. 1-4 built by the Ministry of Construction. The soil in Beit Shemesh is complex, problematic and contains chalky and marlstone areas. The marlstone areas are problematic due to the widespread of the sliding phenomenon in them. The solution: In chalky areas, the foundations used were usually based on micro-files or regular piles. On the other hand, the marlstone, which is a weak rock with swelling potential, requires deep foundation with piling machines as well as treatment of slope sliding. These factors made the solutions more expensive and complicated.

The "Briga Towers" project by Yuger Consulting won the 2021 Construction Excellence Award A complex construction project, which was accompanied by Yuger Engineers Soil Consultants Offices, won a prestigious award from the "Excellence in Construction" competition of the Haaretz Builders Contractors Association, the Foundation for the Encouragement and Development of the Construction Industry and out of a hundred projects submitted to the competition. The prize was awarded to the project " Briga Towers" in the category of "Residential building of ten stories or more. The towers are located on the coastal strip of Netanya, and include two 34-story towers with 14,000 square meters of recreational areas and 208 apartments and were built with an investment of about 800 million shekels. The complexity of the route and the nature of the soil, the proximity to the sea and the complex construction challenges required a particularly thorough and professional soil consultation. This is how the win was justified, on the committee and with reference to the environmental planning and development challenges in which Yuger Soil Consultants was also involved: "Each tower is covered with aluminum 2200 double glass to maintain complete insulation and withstand the weather of the coastal area. During the construction, a variety of innovative technologies were used, and emphasis was placed on Regional development and advanced environmental planning." The urban and environmental space The project is located about 300 meters from the beach of Netanya in the 'Ir Yamim' neighborhood . The investment in the development of the neighborhood and t he suitability of the infrastructure stems from its unique location and the influence of the maritime space, the dune sand and more on the construction and the urban space, hence the need for a thorough examination of the land and the constraints it brings with it and the presentation of technological-infrastructural solutions for the construction process so that it remains economical. It will allow, and as the mayor, Miriam Fierberg-Icher, explains: "The new neighborhoods are enjoying unprecedented success, both locally and nationally, mainly thanks to their level of finish and the development of the preliminary infrastructure - which is often done before occupancy." The uniqueness and professionalism of the firm of soil consultants Yuger Eng., allowed it to accompany this unique and prestigious project and based on the value engineering approach allows saving the costs of the project and on the basis of studying and examining its various engineering aspects and formulating recommendations for changes in planning and implementation while maintaining the quality of the final product.
