M/s. ICT were constrained to develop the x-sections of 4 laning accordingly. This had the following inherent drawbacks: i) ii) Non availability of space for 4.5m wide Median as per Ministry’s / NHAI guidelines Non Provision of 1m wide earthen shoulders on both sides of the 4-lane road services iii) Only 5.5m width of service roads including 1.5m width for side drain and 0.5m for utility iv) No space for stacking lane for turning traffic in medium opening for safety v) Non availability of adequate space for utility services vi) No space for bus bays, bus shelters, parking areas etc. vii) No scope of future expansion 0.3.2 Reports Submitted Feasibility report of the project was submitted to NHAI on 13.02.2006. Draft Preliminary Project Report for Package II i.e. km 465.000 to km 551.900 was submitted to NHAI on 12.01.2007. These reports were based on the earlier decision of 4 laning in the existing 30m Right of way (ROW) width. 03.3 Later Developments During the meeting taken by the Hon’ble Minister for Shipping, Road Transport & Highways with the Chief Minister of Kerala at Thiruvananthapuram on 23rd May 2007, it was decided that 4-laning of NH-47 from Cherthalai to Thiruvananthapuram will be carried out in 45m. Right of Way (ROW) width and NOT in 30m existing ROW as desired by the State Govt. of Kerala. This has resulted in complete change of design and drawings by the consultants. Monthly Progress Report 1 - 2 • Due to change in ROW width from 30m to 45m new cross-sections for 4-laning were developed and sent to NHAI for approval on 31.05.2007 and 06.07.2007.

Design Chainage 544.150-544.160 Remarks Natural Drainage Channel PAVEMENT CONDITION SURVEY The Pavement Condition Survey on the project road was carried out, to assess the condition of existing pavement. The condition survey was carried out by using ROMDAS (Road Measurement Data Acquisition System) as well as by visual assessment. Pavement surface distress indicators like pot holes, cracks, ravelling, patching, conditions of shoulders and embankment had been carefully observed and the detail information were collected using approved QAP formats. 4.1 Corrugation Corrugations are the formation of fairly regular undulations (ripples) across a bituminous surface. They are usually shallow and are different from the large depressions caused by weakness in the lower layers of pavement or sub-grade. The corrugations can be a source of discomfort to the user and can become a hazard, if allowed to become severe. The Consultant has not observed any measurable corrugation, in the project road. 4.2 Rutting Rutting is a longitudinal depression or groove in the wheel tracks. The ruts are usually of the width of a wheel path. Swerving from a rutted wheel path at high speed can be dangerous. The depth of rut is measured by keeping the straight edge placing transversely across the wheel tracks and using graduated measuring wedge. The mean value for the wheel tracks is worked out. 4.3 Pot Hole Potholes are bowl shaped holes of varying sizes in a surface layer or extended into base layer, caused by the localized disintegrations of the usually thin bituminous surfacing material. The area affected by major Pot holes was measured and the percentage area was worked out. 4.4 Ravelling Monthly Progress Report 1 - 26 Ravelling is characterized by the progressive disintegration of the surface due to the failure of the binder to hold the materials together. Ravelling was measured at every 500m. 4.5 Cracking A common defect in bituminous surface is the formation of cracks. The area affected by cracking was measured by encircling and the extent of cracking was assessed visually at 500m intervals or the places of defects. 4.6 4.7 4.8 Patching During field inspection, patching was observed at the stretches. Edge Breaking Irregular breakage of pavement edge was noticed in some portion of road. Edge Drop The edge drop is the vertical difference in levels between the edge of the carriageway and abutting shoulders. 4.9 Inventory of all Road Side Facilities The details of the road side amenities and facilities like school, dhabas, telephone booths, bus stop, hospital, hotel, repair shops etc. are given. 5. 5.1 ROAD MEASUREMENT DATA ACQUISITION SYSTEM (ROMDAS) Background The roughness has been carried out for the whole length of the project road using Road Measurement Data Acquisition System (ROMDAS). The calibration of the ROMDAS has been done as per the procedure given in World Bank’s Technical Paper Number 46 (WTP46). The surveys have covered two runs along the wheel paths for each lane and results have been expressed in the terms of IRI (m/km) and BI (mm/km) in tabular as well as graphical forms. Further, whole stretch of 162 km has been delineated using Cumulative Difference Approach and based on this homogeneous sections have been identified. In addition video survey has also been conducted for digitisation of whole project road to have a better in-house assessments and rectifications. 5.2 ROMDAS Road Measurement Data Acquisition System (ROMDAS) has been developed as a generic system for collecting a variety of information. The vehicle mounted equipment includes: an axle mounted device called Bump Integrator for the measurement of roughness; a Video camera and an IBM compatible notebook PC which interacts with the instrumentation to store recorded data. The video camera is used to record all pertinent information concerning the existing roadway and Rightof-Way (though, whenever necessary, this information may also be verified by physical inspection). Road Roughness Surveys The axle-mounted ROMDAS Survey Module is used to measure pavement roughness. Introduction This is an indication of the surface irregularities influencing the riding quality and is a major determinant of vehicle operating costs. ROMDAS works as a response type road roughness measuring system. The system has been calibrated by recording its response (RAW values) and comparing the same with that of a ROMDAS Z-250 Reference Profiler. ROMDAS Z-250 reference Profiler has been developed by Data Collection Ltd (DCL). The Calibration sections called standard sections have been divided into a number of smaller subsections of 100m lengths each. A total of 12 such “standard” points have been collected consisting of 400 lengths each. “Standard” sections vary from “very smooth” to “very poor” and at each section the Z-250 has been run along the selected lane and roughness has been noted in terms of IRI (m/km). ROMDAS vehicle has been run at Constant Speed of 32+2 km/hr on the “standard” section along the same selected lanes and ROMDAS response (RAW values) have been recorded. Using the software-NLREG the calibration equation has been developed between ROMDAS Response (RAW/km) and IRI (m/km). Calibration equation at 32km/hr: Y = 1.583+0.00047*X [R^2 = 0.98] Where X is ROMDAS Response (RAW/km) and Y is IRI (m/km). IRI Roughness values have been converted into Bump Integrator Index (BI) by means of the equation given in HDM-III: BI = (312.5 x IRI) 1.124 Field data collected and analyzed subsequently along each lane of the stretch have been expressed in terms of IRI (m/km) and BI (mm/km) and have been presented in both tabular and graphical forms in the following pages. 5.3 Limitations as per MOSRT&H/World Bank The following guidelines for road roughness in terms of IRI (m/km) and BI (mm/km) for different surface types have been considered for assessing the road condition. a) Recommended Roughness values (BI units) by MORT&H Circulation No. RW/NH33044/10/2000-S&R dated 22nd May 2000 Surface Type Bituminous Concrete Premix Bituminous Carpet Surface Dressing Good (mm/km) 2000-2500 2500-4500 4000-5000 Average (mm/km) 2500-3500 4500-5500 5000-6500 Poor (mm/km) 3500-4000 5500-6500 6500-7500 Very Poor (mm/km) >4000 >6500 >7500 As per World Bank Technical Publication No. 46 the minimum and maximum range of BI and IRI for new pavements is as follows, but the type of surface has not been mentioned. Monthly Progress Report 1 - 28 Minimum IRI New Pavement s 1.5 (1000) 5.4 Observations (BI) in m/km(mm/km) Maximum IRI (BI) in m/km(mm/km) 3.4 (2500) Based on the Roughness Measurement Studies the km-wise average roughness in IRI and BI Units of various lanes. The detailed 100m-wise Roughness Measurement Studies have been provided. 6.

CROSS DRAINAGE WORKS 105 number cross drainage structures are existing in project main road and 6 no culverts exist in Kollam by pass. All These culverts has been examined in detail during feasibility study and their retention and widening or new construction after dismantling has been proposed after conducting conditions survey. Some of the desired information could not be obtained due to blockage of culvert either by sedimentation or due to grow of thick bush inside the culverts, or due to existence of muck at inlet and outlet. The scouring at inlet and outlet is predominant and same is required to be taken care by suitable preventive protection works. The required widening of the culvert proposed to be retained, as per profile layout is to be undertaken as per the general arrangement drawing, provided in drawing volume. Abstract of existing culverts are given in Table 10 and Table 11. Table 10: Abstract of Culverts (Main Road) Sl.

Introduction • There are 14 existing Bridges in the existing road stretch. Two number bypass has been proposed to be bypass Kollam and Attingal towns. 3 number new bridges are proposed in Attingal bypass and 6 number new bridges are proposed in Kollam bypass. Other 5 nos existing bridges of NH-47 are of 2 lane and are required to be widened to 4 lanes except the AS Canal Bridge at existing Km 482. The hydrological study, computations and methodology adopted for discharge and other hydrological computations have been discussed in this report. List of proposed culverts are included for bypasses. • • 9.2 Study Objective These investigations are primarily intended for evaluating the adequacy of waterways of the existing bridges for the design flood flow. The hydrological study has been done based on the field investigations and survey data. This report describes the method of evaluation of performance of existing bridges on the existing highways for widening proposals, and design discharges, waterway required, scour depth and afflux etc for the new bridges. Hydrological Investigation Pertaining to Bridges There are total 14 bridges on existing main road out of which 9 bridges are proposed to be bypassed. Major rivers, Canals and lakes crossing the proposed alignment are outlined below: • 9.3 Among Existing bridges 2 number bridges are on defined river Ithikkara at design chainage 505+300 and Pallipuram at chainage 544+155 .One bridge is on famous Ashtamudi Lake at chainage 484+900. Other 2 number bridges are on canal at chainage 471+880(Pallikal) and other is at 480+150 (TS canal). 6 number bridges are proposed on Kollam bypass among which 3 no bridges are proposed on the lakes and other 3 number bridges are on the different branches of Churanga thodu river. Total 3 number bridges are proposed on Attingal bypass among which Two bridges are proposed on the major river Vannapuram at chainage 529+300 and Mammon at chainage 534+110 river of Periyer Basin. One minor bridge is proposed on Thotakadu river at chainage 529+600. Bridges are found to be of varying span of 8 m to 423 m ( on lake) River slope in the bypass are generally found to be varies from 1 in 250 to 1 in 1000. General ground are varring from RL 60 on the waterdivide to RL 0 on bridge site. Vannapuram river generates at Ranges of Sayhadri hills of elevation 1100 . • • • • • 9.4 Hydrological Data The Hydrological Data collected for calculation of bridges are as follows: Various data such as terrain, soil and cover condition, nature and size of bed material, river bed and plan forms etc. are collected from field through local inquiry made during site inspection by engineer based upon designed format for the same. Table 12 shows the hydrological features such as bed level and HFL of Channels. Toposheet Number 58C/12, 58C/16, 58D/9, 58 D/13, 58D/14, 58 H/2 of has been taken from Survey of India and catchments of streams has been demarcated. Equivalent Slope of stream , terrain slope and land uses are also studied in the toposheet. Rainfall/runoff data published in the Flood Estimation Reports for West Coast Region Sub zone 5a & 5b, prepared jointly by Central Water Commission (CWC), Indian Meteorological Department (IMD), Research Designs Standards Organisation (RDSO) and Ministry of Shipping Road Transport & Highways (MOSRT&H) are used for information regarding stream flow and rainfall. From Isopluvial maps in Flood Estimation Report, 24 hour rainfall of 50 year return period is found to be 280 mm for this stretch of road. The rainfall data has been given in Table 13. Monthly Progress Report 1 - 32 Table 13 : Rainfall Data Stretch Trivandrum to Cherthalai Mean Annual Rainfall 1000 mm to 4000 mm 24 hours Rainfall for Return period of 25 Years 240 mm 50 Years 280 mm 100 Years 320 mm For rain fall of shorter duration less than 24 hrs a conversion ratio has been adopted from same CWC report. Mean average Time distribution curves of storms of various duration are also adopted from CWC report subzone 5a and 5 b Aerial to point rainfall ratio for various duration over different catchment is adopted from CWC report of Subzone 5 a and 5 b. The general land use data and Soil Data are also adopted from the same report. 9.5 Stream Data For all the bridges, the longitudinal section of the river extending from about 100m to 500m on the U/S and 100m to 500 m on the D/S (depending on stream size) has been drawn on the basis of actual survey data at site. Several river cross-sections, one at the bridge site, others both U/s and D/S of the bridge are drawn on the basis of field survey data. Longitudinal section of the stream along deep channel is plotted for each stream to find the longitudinal bed slope and compared with terrain slope found from toposheets. Manning’s roughness coefficient (n), cross section area of flow (A), wetted perimeter (P) and conveyance (K) etc. are found for each of the stream. 9.6 Hydrological Computations Pertaining to Bridges The adequacy of the existing bridges has been determined on the basis of design discharge / flow. The detailed hydrological computations for all bridges on existing main road and bridges on bypasses have been done. The discharge has been computed by various methods and then finally, design discharge has been adopted as recommended in IRC:SP – 13 and IRC : 5. The computed discharge is given in Table 14. It also gives other details e.g. names of streams, existing clear waterway, skew angle, effective waterway, design discharge and HFL as obtained from local enquiry. The adequacy of the existing bridge is determined by taking into consideration of Lacey’s Regime waterway and actual waterway (at HFL) of the channel and is given in Table 15 & Table 16 gives the abstract of hydraulic parameters e.g. design HFL, maximum scour levels for piers and abutments, recommended
