CASE HISTORY Rev: 00, Issue Date 21.05.09 Transportation/Monorail Product:Mactex WR 10 MMRDA FABRICATION YARD AT WADALA MUMBAI,INDIA Photo 3. Unraveling of Geosynthetic roll Client name: MMRDA Main contractor name: L & T LTD. Mactex WR 10 - 13,705 sq m Construction info: Consultant: Products used: Construction Start: SOWIL LTD. 2009 ON GOING PROJECT Construction end: Photo 2. Transportation of roll of Woven Geosynthetic Mactex WR 10 of size 3.2m x 147m Photo 1.Site Before Construction Problem: Solution: Considering the increase in population, increased travel demand and narrow road networks running through congested areas, there is a need of a system which will occupy less space as well as reduce travel time. Maccaferri Product Used: Mactex WR 10 is used in Basal Reinforcement for strip footing which will give strength & enhance the Bearing & load carrying capacity of existing very loose soil. MMRDA has proposed to construct the 20-km elevated monorail, the first such project in India which would start at Jacob Circle in south Mumbai and termi- nate at Chembur via Wadala. The Rs. 2,460-crore project, awarded to Larsen and Toubro and Malaysia-based Scoomi Engineering, is to be completed in 30 months. It is proposed to replace the existing soil with good frictional soil along with some reinforcement to enhance its load carrying capacity. Hence approximately 800mm soil is dug out and replaced with frictional soil. A soil is placed in three different layers I st Layer – 300mm,II nd Layer – 250mm and III rd Layer – 250mm. As part of the monorail project a casting yard is proposed to be constructed near Wadala (W). The casting yard is expected to carry a total load of 20T coming from the gantry. The casting yard will be constructed in stages and the first phase of casting yard has an area of 64m X 15m. The existing soil on site was very loose, which is unable to carry the load due to Gantry. A layer of Woven Geotextile is placed after I ST layer of frictional soil and above that other layers of frictional fill area supposed to be placed with proper compac- tion.
