The biggest problem in building out infrastructure (or doing any work for that matter) in India is I think the complete disregard of bureaucrats to do things on time. A simple contract award can take anywhere between 1-12 months to get Work Order after tender is awarded. There seems to a massive chain of veto holding interests that holdup work and cost time.

Secondly making payments on time is an alien concept both in personal, public and private sector in India (Kal/Baad mein aao... aaj nahin hain syndrome). To resolve the payments issue I have proposed that contracts are written to ensure that payments be made first and burden of proof that work has not been done falls upon the employer rather than the present case where the vendor has the burden of proof that the work has been done. This typically manifests itself when a vendor raises an invoice and suddenly the client wakes up and starts finding fault in the works done which were absolutely fine before the invoice was raised.

Contract payment system proposed
1) NECS/ECS mandate be signed by client to the vendor which allows monthly payments (as per predecided schedule and amount) to be deducted directly from client account while the work is progressing.
2) Client can terminate the contract (by submitting a NECS stop order form and/or a NECS reverse transfer of a certain amount) if they find the work is substandard or incomplete and process action to recover payments rather than the present case where vendors have to move heaven and earth to get their payments.
3) National contracts/invoice registry system (have some real nice startup ideas around this but need technical help to get it off the ground)

India’s grand plan to create world’s longest river set to go
Engineering projects don’t come any bigger than this. If India’s prime minister, Narendra Modi, gets his way, work could soon begin on a project to link large rivers in the Himalayas and Deccan Peninsula via 30 mega-canals and 3000 dams.When the work is finished the water network will be twice the length of the Nile, the world longest river, and it will be able to divert water from flood-prone areas to those vulnerable to drought.But geologists and ecologists in India question the science behind the Inter Linking of Rivers (ILR) scheme. If it goes ahead it might lead to ecological disasters and coastal erosion that would threaten livelihoods and endanger wildlife.And yet New Scientist has learned from the officials close to the project that work on the pilot link is likely to “start any time soon”, with final clearance from the ministry of environment and forests expected imminently.Versions of the ILR scheme date back more than 60 years to the days of British rule in India. In its latest incarnation the plan is to link 14 rivers in north India and 16 in the western, central and southern parts of the country, creating a water network some 12,500 kilometres long. The idea is to reduce droughts and floods and create 35 million hectares of arable land in the process, as well as the means to generate 34,000 megawatts of hydropower.

This project is backed by Narendra Modi, who became the country’s prime minister in 2014. Since then India’s National Water Development Agency has completed detailed project reports for three key initial river links – the pilot link between Ken and Betwa rivers in northern and central India; Daman Ganga and Pinjal rivers in western India; and Par and Tapti rivers in western and central India. A feasibility report of a fourth link between three Himalayan rivers – Manas, Teesta and Ganges – is in the final stages of preparation.But many researchers question the science behind the scheme. They say there isn’t a simple division between river basins that carry too little and too much water – and that climate change has triggered changes in rainfall patterns with unpredictable knock-on effects on water flow.They argue that it would be unwise to set in stone a vast new canal network at a time of dramatic environmental change.A study published in July builds on this. Climate modelling once predicted that India’s dry areas will become drier and its wet areas wetter, but this is no longer the case.

A team of scientists from the Indian Institute of Technology in Bombay and Madras found a significant decrease in the monsoon rainfall over major water surplus river basins in India. The team’s computer simulations showed that the water yield in surplus river basins is decreasing but it is increasing in deficit basins.”What may appear as water deficient today may become water surplus in the future due to climate change,” says study author Sachin Gunthe at Indian Institute of Technology, Madras. “So, how do you justify inter-linking?”Geologists are concerned, too. Over the millennia India’s landscape has gradually evolved with the natural flow of water. “Most rivers are fed by monsoon rains and have built large floodplains and deltas over the years,” says Vedharaman Rajamani at the Jawaharlal Nehru University in New Delhi. “Pushing rivers around through ILR disrupts the supply of sediments and nutrients downstream.”“Rajamani says the presence of excess fresh water in the Bay of Bengal delta is especially crucial, as it helps create and maintain a layer of low salinity in the bay, which is one of the several complex, interlinked factors that influence the onset of the Indian summer monsoon. Artificially manipulating the natural system could disrupt the monsoon rainfall in the region, he says.Rajendran says that the huge amount of water in dams would increase the water pressure in the cracks and push on crust below, possibly increasing the risk of earthquakes in the already quake-prone Himalayas..Ecologists are concerned too. A pilot project in the ILR scheme – the Ken-Betwa link – would be built at the cost of destroying an estimated 4100 hectares of forest. This might include 58 square kilometres of the Panna Tiger Reserve – 10 per cent of the reserve’s area. And yet it got the official approval in September.The government, however, has stayed dedicated to the idea. Interlinking rivers is an attempt to boost water supply to the needy states, says Vijay Goel, junior minister for water resources.But while the project looks grand on paper whether it turns out to be a success or a disaster remains to be seen.

Wonderful leg-up for the logistics sector. DHL sets up a wholly owned trucking company in India aiming to own 3,500 trucks by 2020.

DHL launches transportation company; aims to own 10,000 trucks by 2028
"We have been checking all the different markets we are in worldwide. And looking at what's been going on terms of technology. We have been looking at our customers, our value chain, the white spots where we can add something. That was the main idea that led to SmarTrucking...to do something that's missing, especially in India...to cover this white spot we had in terms of trucking. Bringing in more expertise in terms of the tech perspective and doing something more in terms of people and HR. The whole story is 10 years. This is the focus we have: to think about the next decade. We have a few milestones and control points to see if the business is doing well," said Juergen Gerdes, CEO of the Post-eCommerce-Parcel division of DPDHL.

Gerdes said SmarTrucking is a unique model of a 100% owned fleet for DPDHL which usually follows the asset-light model of leasing vehicles. He added he expects the company to transport 100,000 tonnes of cargo and cover a distance of 4 million kilometers across India daily.

"This industry is under-invested in terms of technology. We are setting up what we want to do in terms of techlog--technology enabled logistics," said Neeraj Bansal, CEO of SmarTrucking.

Sales of M/HCVs (medium and heavy commercial vehicles) hit an all time high in 2017-18 . After the previous business cycle petered out in ~2011, commercial vehicle sales took 6 years to overtake the previous annual sales record, which was finally smashed in 2017-18. The current fiscal 2018-19 is looking like another strong year.

GST and the elimination of bottlenecks in interstate commerce makes a massive difference.

Armed with Guinness record, Navayuga now eyes global markets.

Engineering and construction firm Navayuga Engineering Company (NEC), which on Monday secured the Guinness World Record for largest continuous concrete pour at Polavaram irrigation project, will now eye global markets with world-class equipment and expertise in completing critical projects in record time.

Polavaram irrigation project in Andhra Pradesh is the world's largest flood discharge dam currently under construction, involving Rs 57,000 crore in outlay including land acquisition, rehabilitation and resettlement. The project would irrigate a total of 42 lakh acres of ayacut in two phases, supplying water to all 13 districts of Andhra Pradesh. Ayacut is the area served by an irrigation project.

The irrigation project, considered the lifeline of Andhra Pradesh, involves 48 gates, each 20 metre high spanning 1.19 kilometres, requiring pouring of 36.7 lakh cubic metres of concrete, 50,000 tonnes of steel and 9.3 lakh tonnes of cement, which was all completed in in record time. It also includes a 930 MW hydel power project.

NEC Managing Director Chita Sridhar told ET the company is currently looking to execute Rs 30,000 crore of projects on hand over next three years to break into India's top ten engineering and construction companies. NEC is executing around Rs 3,400 crore of civil works of Polavaram project, apart from Rs 3,000 crore of hydel power project on EPC (engineering, procurement and construction) basis.

On Monday, NEC, the flagship of Rs 25,000 crore Navayuga Group, secures the Guinness World Record for pouring 32,315 cubic metres of concrete in 24 hours at Polavaram project, announced Rishi Nath, adjudicator at Guinness World Records. It surpassed the previous Guinness World Record of 21,580 cubic metres of concrete continuous pour by the consortium of Abdul Wahed Bin Shabib, RALS Contracting LLC and Alfa Engineering Consultant in Dubai during May 2017.

The engineering marvels that NEC boasts of completing way ahead of the deadline include India’s longest river bridge Dhola-Sadiya, complex river management system Dibang-Lohit River Management System, the longest highway tunnel project Quazigund to Banihal, and the largest port on India’s east coast, Krishnapatnam Port.

“All these projects were highly complex engineering and construction marvels that we completed way ahead of the prescribed timelines, reducing the timelines by at least a third,” said Sridhar, “We could record such accomplishments thanks to not just our own engineering designs but also specially designed engineering tools in-house.”

“The incredible engineering feat of world’s most concrete continuous pouring in 24 hours achieved on Monday was accomplished with around Rs 2,000 crore of machinery and over 4,000 men enabling us to exhibit our engineering and construction capabilities to the world,” said Sridhar. “The dam construction of large irrigation projects normally involves six years of time and we can now offer to execute such projects within four years.”

NEC is looking to bid for dam projects and hydel projects in Africa, Bhutan besides other countries. In the overseas market, NEC is currently executing a few works in Qatar.

Navayuga group owns Krishnapatnam port on India’s east coast, and is currently building Machilipatnam port in Andhra Pradesh and Astaranga port in Orissa, also on the eastern seaboard of India.

“The works of Machilipatnam port are expected to take off soon and we are confident of completing the project within 18 months,” said Sridhar.
NEC hopes to complete most civil works of Polavaram irrigation project by June this year and start exploring similar projects where the equipment can be deployed.

Hoping to touch a topline of Rs 6,000 crore this fiscal, NEC is eying finishing about Rs 30,000 crore of projects to hand over the next three years. “We expect to achieve Rs 10,000 crore of topline in couple of years.”

quiet revolution is the right word.

with GST , places in central india like nagpur are emerging as logistical hubs, apart from usual places like metros (close to biggest markets) and sea ports.

some of it is still low tech as the patanjali warehouse in this video, but the scale is visibly there....better inventory mgmt and racking systems will surely come for quicker turnarounds and better stock management

what we need now is better freight corridors between MUM-CCU, DEL-HYD-MAS, BLR-MUM by tripling or doubling of tracks (like the pathetic single line BLR-MUM). no need for separate corridor like DFC but atleast 1-2 more parallel lines along existing routes. will improve the avg speed of all trains.

we need to be the worlds biggest road and rail builder for a decade. let mountains of steel and concrete be poured everywhere.

there is no visible movement on retendering of the vital ORR metro (that too just half of it) in blr after L1 winner IL&FS became insolvent.
this was supposed to be done months ago by BBMP.
this when the line will be viable and overused from day1 and corporates in each tech park have already donated money and land for the stations.

The previous funding scheme has been scrapped and
BBMP is seeking central funding for the line. For that they need to adhere to some central norms like CMP and UMTA as per this report.

https://www.metrorailnews.in/centre-to- ... o-project/

Knowing the pace at which bbmp works lets hope they implement it soon.

It would be interesting to see which of these projects gets completed before 2030 , 25 km ORR line or 1700 km chengdu - Lhasa line.

Under the Jal Jeevan Mission, both ground and surface water will be used to meet the requirement. Union drinking water secretary Parameswaran Iyer said in villages where the quality of water available is good, piped water will be sourced and supplied at the village level. In other areas where water quality is poor, there will be a trunk water supply system for a cluster of villages and piped water will be sourced from other villages or locality. The communities such as village panchayat would manage the operation and maintenance of the facilities wherever feasible.

Officials said the focus of the scheme will be to recharge groundwater through point recharge sources, basic treatment and re-use of grey-water for agriculture, de-silting minor irrigation tanks and rejuvenation of water bodies. “There will be a huge focus on the campaign for creating awareness and behaviour change for the conservation of water,” an official said.

This needs a countrywide contour mapping at 2m height difference to be made... we need to create a network of water holding structures whose over flows are interconnected. This will reduce the erosion of soil and help improve ground water tables, Each entrance to water body should be protected with vortex / passive silt traps to ensure that water holding capacity is maintained and mud does not enter the water structure... this improves the potability of the water

Here is something that might prove useful to cities at the coast like Chennai: https://phys.org/news/2019-06-hot-effic ... ation.html
Engineers boost output of solar desalination system by 50%

In conventional membrane distillation, hot, salty water is flowed across one side of a sheetlike membrane while cool, filtered water flows across the other. The temperature difference creates a difference in vapor pressure that drives water vapor from the heated side through the membrane toward the cooler, lower-pressure side. Scaling up the technology is difficult because the temperature difference across the membrane—and the resulting output of clean water—decreases as the size of the membrane increases. Rice's "nanophotonics-enabled solar membrane distillation" (NESMD) technology addresses this by using light-absorbing nanoparticles to turn the membrane itself into a solar-driven heating element.

Apple has asked its major suppliers to evaluate the cost implications of shifting 15% to 30% of their production capacity from China to Southeast Asia as it prepares for a fundamental restructuring of its supply chain, the Nikkei Asian Review has learned.

The California-based tech giant's request was triggered by the protracted trade tensions between Washington and Beijing, but multiple sources say that even if the spat is resolved there will be no turning back. Apple has decided the risks of relying so heavily on manufacturing in China, as it has done for decades, are too great and even rising, several people told Nikkei.

"A lower birthrate, higher labor costs and the risk of overly centralizing its production in one country. These adverse factors are not going anywhere," said one executive with knowledge of the situation. "With or without the final round of the $300 billion tariff, Apple is following the big trend [to diversify production]," giving itself more flexibility, the person added.
Although Apple supplier Wistron has assembled cheaper iPhones in India since 2017, and Foxconn from this year, volumes have been very small. More than 90% of Apple's products are assembled in China. Last year, the number of mainland Chinese and Hong Kong-based suppliers surpassed those in the U.S. and Japan for the first time, accounting for 41 of the top 200 suppliers, according to Nikkei research.

The countries being considered for diversification include Mexico, India, Vietnam, Indonesia and Malaysia. India and Vietnam are among the favorites for smartphone diversification, the people said, who asked for anonymity as the discussions are private.

Not sure if this is the right thread...but first phase of Jayadeva Flyover demolition in Bengaluru will commence from Monday July 15. First phase involves demolition of ramp coming from Bannerghatta road towards Silk Board Junction. But BLR traffic police have given assurance that alternative routes...

Overall reconstruction including new 6 lane flyover and two metro lines will be done in 2-3 years I think. We know nothing in India (& many of other places in the world) gets done on time...people using that route need to brace for traffic hell for the next 3-4 years. This will also crowd other alternate routes towards Agara/ORR...Fun times ahead.

Most companies in the Real Estate, Construction and Infrastructure sector are deep trouble. Many are defaulting on loan repayments, salary and tax commitments.

The root cause for those in Govt Infra space is beauracratic delay of payments for 6 months or more and frequent political U-turns on awarded contracts which happens everytime govt changes. Root Cause for companies in Real estate is lack of buyers probably due to lack of money supply due to payment delay from Govt projects and unrealistic value demanded. Most of this is coming from hyper inflated value of land which developers have paid to politically connected folks.

https://www.livemint.com/politics/polic ... 16973.html
Everything mentioned in this article has been personally experienced by us in last 6 months 1) tax terrorism (gst official locking out our bank account and garnishing money) 2)payment delay in govt sector to MSME sector is 48000 Cr (last para) we are vendors to infra companies and most have expressed inability to pay us 3) When big companies like L&T are facing losses the situation is more dire for smaller contractors

Was travelling from Chandigarh to Shimla and back. Very poor road infra implementation. Himalayas are young essentially loose rock mountains. Extremely unstable terrain with persistent rock fall due to mountain cutting activity and rain/water infiltration induced destabilization.

I found that in most locations creating a 30m (4lanes) wide carriage required 100m vertical cut of mountain. This vertical cut actually exposed more loose rock which keeps falling on carriage way. Which essentially meant that 2 lanes were consistently unavailable at all times.

It seemed to me that creating roads bridges on pillars was a technically superior and economically superior solution than cutting mountains to make roads

Piped water: Over 50% jump in rural areas in 14 months
Piped drinking water reached about 5.74 crore rural households or 30% of such households as on last Thursday, compared with 3.24 crore (17%) as on August 15 last year, when Prime Minister Narendra Modi unveiled the Jal Jeevan Mission (JJM), according to the official dashboard. This represents an impressive over 50% jump in 14-and-a-half months.

Despite the Covid-19 pandemic, 1.67 crore new rural households, including 1.06 crore under JJM, have been added to functional household tap connection (FHTC) network in the country so far in FY21.

This is absolutely a brilliant point! I seem to have somehow missed the post when it was made. Hence the delayed response. Clearly there is a case for for in depth cost-benefit analysis on different ways creating an access through mountainous terrain between chiselling more of the mountain and creating an overpass on what has already been chiseled.

In USA most developments have a mandatory detention pond on the premises that are designed to hold storm water and release it over 48 hrs. In India these rain water retention ponds have become real estate causing all these problems. Poor city planning illegal colonies and even worse implementation is to blame

Amid concerns over China’s hydropower project on Brahmaputra, India plans multipurpose dam in Northeast.
India to build multipurpose reservoir in Arunachal Pradesh! Amid concerns over a major hydropower project being developed by China on the Brahmaputra river in Tibet, India now plans to develop a multipurpose reservoir in the northeastern state of Arunachal Pradesh. Commissioner (Brahmaputra and Barak) in the Jal Shakti Ministry, T S Mehra was quoted in a PTI report saying that the multi-purpose 10,000 MW hydropower project is under consideration right now. According to Mehra, this hydropower project will help offset the impact of China’s hydropower project. It is being said that the proposed 9.2 BCM ‘Upper Siang’ project on the Siang river will be able to take the excess water discharge load and in case of any deficit, it can even store water.

According to Mehra, during monsoon season, Brahmaputra’s 90% water comes through its tributaries in India due to the abundant rainfall in the northeast part of the country. It is only during the winter season that the Siang river gets its 80% water from the upper stretches as glaciers become the main source. According to another senior official of the Jal Shakti Ministry, since the 1980s, the project has been under discussion, further pointing out hindrances in the project’s execution.

I am sure somebody much more intelligent than me can explain this.

Should India use Foreign Exchange Reserves for Financing Infrastructure?

Ladakh gets Centre's nod for transmission lines at revised cost of Rs 1,310 crore.

The central government has approved intra-state transmission works at a revised cost of Rs 1,309.71 crore to link far-flung villages of Ladakh to the grid and phase out DG sets towards achieving carbon neutrality in the Union Territory, a top official said on Saturday.

The project on completion would also provide the army and the far-flung villages with clean power round the clock, he added.

Congratulating the people of Ladakh on the approval of the project, Lt Governor R K Mathur said the intra-state transmission works have been sanctioned by the Union Ministry of Power and include 220 KV S/C transmission lines of D/C tower (total 307 km), including KargilPadum (Zanskar) (207 km) and Phyang to Diskit (Nubra) (100 km) and two 220/33 KV Grid substation – one each at Diskit, Nubra (50 MVA) and Padum, Zanskar (50 MVA) with an outlay of Rs 1,309.71 crore.

The project on completion would also provide the army and the far-flung villages with clean power round the clock. Secretary Power, UT Ladakh, Ravinder Kumar said these projects were part of the Prime Ministers Development Package (PMDP) 2015, which could not have been taken up due to various issues. However, due to the painstaking efforts of the Lt Governor, his administration and public representatives, it is now approved and ready for tendering of works, Kumar added.

He said the REC Transmission Projects Company Limited (RECTPCL) is the project implementing agency for executing the transmission works in Ladakh, while NSE -1.25 % India Limited (PGCIL) is the project management agency.

“These transmission lines will link far-flung villages to the Grid and phase out DG sets used in far-flung villages, thus taking one more step towards achieving Carbon Neutrality in Ladakh. This will also provide the Army and far-flung villages with clean power round the clock.

The DPR cost of the projects has been revised from Rs 354.74 crore to Rs 1,309.71 crore by the Central Electricity Authority (CEA), Kumar added.

World’s tallest railway bridge in Reasi likely to be completed by Dec 2023.

An engineering marvel in the making, the world’s tallest railway bridge being constructed over Chenab river in Jammu and Kashmir’s Reasi district is likely to come up by December next year.

“After completing the main arch, work on laying the track will be taken up shortly. Once the track is completed, it will give impetus to the allied works. If everything goes well, we hope to complete it by December next year,” said an official spokesperson. Union minister Ashwini Vaishnaw had recently shared a picture of the arch over the clouds.

The bridge is 1,315-metre long and will have the distinction of being the highest railway bridge in the world at 359 metres above the river bed level. It is 35 metres higher than the Eiffel Tower in France. Chenab Bridge has 17 spans with main arch span of 467 metres.

This railway bridge is part of the Udhampur-Srinagar- Baramulla Rail Link Project, which is the most challenging project being undertaken post-independence by Indian Railways. The 111-km long stretch is being built at a cost of ₹27,949 crore.

In view of importance of this project in providing seamless and hassle-free connectivity in Jammu and Kashmir, it was declared a “national project” in 2002.

Northern Railway has entrusted the construction of the iconic Chenab Bridge to Konkan Railway as an executing agency. The main arch of the bridge is 467 metres linear length (curvilinear length is 550 metres), resting on two massive foundations on dolomite limestone hillock across mighty Chenab river. The overall weight of main arch is 10,619 metric tonnes.

The erection of the arch has been undertaken from both ends with the help of massive cable cranes of cumulative carrying capacity of about 35MT, using incremental launching by supporting cantilever portion with prestressed stay cables.

The structural detailing of the Chenab bridge, including the main arch, has been carried out in the most sophisticated Tekla software. The Tekla model provides a walkthrough in the bridge, enabling the fabrication engineers to understand the complex details. Technically, the construction of main arch was most significant event, as this nature of work had been undertaken for the first time in country and rarely carried out in the world.

A National Accreditation Board for Testing and Calibration Laboratories (NABL) accreditation lab has been established at the site to facilitate the testing work.

The construction of this project involved construction of 26 km of motorable roads, fabrication of nearly 28,660 metric tonnes steel and more than 80% fabrication has been done at site workshops in Kauri, Bakkal and Surandi.

At the peak of construction activity, nearly 3,200 people were working at this project site. A mini township consisting of about 600 rooms was established in the vicinity of the bridge to accommodate this massive workforce.
