The VAB is 160m high, and its base is 218m x 158m. So this is a huge building, but not in the VAB's category. I keep forgetting how short (let's call it stubby) the VLM3 is.
Yes. LVM3 is shorter than PSLV and GSLV at ~43m. So they can assemble rockets 60-70m high in the new SVAB. Sufficient for future ULV and HLV class, but not for ones beyond that I guess.

Full Duration Test lasting 640 Seconds of the Cryogenic Upper Stage ( C25 ) is yet to take place. I am sure, ISRO will do this full duration test more than once before certifying the C25 Stage.

Full Duration C25 Stage Test will be done tomorrow.

Quote
There will be a full duration flight test of cryogenic upper stage for GSLV MkIII for 640 seconds on Friday, ISRO Propulsion Complex (IPRC) director, P V Venkitakrishnan, told Express on the sidelines of the successful launch of PSLV C-37.

The full stage demonstration at sea level is scheduled to be held at IPRC, Mahendragiri. "If we succeed in our mission for 640 seconds, it will be an important milestone and ISRO can launch GSLV MkIII by April," Venkitakrishnan said

He said the agency had successfully ground tested its indigenously developed cryogenic engine (C25) at a High Altitude Test (HAT) facility on January 25, 2017 and integrated it with the flight stage.

"The performance of the engine at high altitude during the test was satisfactory and Friday's test would be the last in the series before going for an actual rocket launch," he said and added, "Already, earth-storable liquid core stage (L110) and solid strap-on-motors (S200) have been integrated and reached Sriharikota. C25 engine activity and integration is progressing in IPRC and should be ready for dispatch in couple of weeks."

Reports have started coming in of the successful full-duration test of C-25 stage at IPRC. Official report from ISRO sources is yet to come.

ISRO conducts cryogenic engine-D stage test

Quote
ISRO successfully carried out its indigenously developed cryogenic engine-D stage test at its liquid propulsion complex at Mahendragiri in the district today.

ISRO Chairman A S Kiran Kumar said "the full duration flight test of cryogenic upper stage for GSLV-Mk III was successful."

The successful test of C-25 payload capacity of four tonnes class of satellite would pave way for the launch of GSLV-Mk III C-25 satellite. The engine will be put into use in April.

Today's test was the last in the series before going for an actual rocket launch, he said.

Since this was last planned test for the stage, we can expect the stage to be shipped to SDSC for integration soon.

ISRO Successfully Tests its Cryogenic Stage (C25) for GSLV MkIII for the Flight Duration

The Indian Space Research Organisation (ISRO) successfully tested its indigenously developed Cryogenic Upper Stage (CUS) for GSLV MkIII on February 17, 2017. The cryogenic stage designated as C25 was tested for a flight duration of 640 seconds at ISRO Propulsion Complex (IPRC) in Mahendragiri. C25 Stage had earlier been tested successfully for 50 seconds on January 25, 2017 to validate all the systems.

Prior to Stage development hot tests, three CE20 engines were realised and two engines were subjected to qualification tests in sea level conditions. This included 800 seconds duration hot test and the third engine identified for flight was tested in high

Altitude conditions for a duration of 25 seconds.

This Stage test is a significant milestone as it is the last in series of engine and stage development hot tests before the first development flight of GSLV MkIII.

The C25 stage is the most powerful upper stage developed by ISRO and uses Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) propellant combination.  The stage carries 27.8 tons of propellants loaded in two independent tanks. Development of a cryogenic stage has unique design challenges, with liquid Hydrogen stored at -253 deg C and liquid Oxygen stored at -195 deg C in its tanks. To store these cryogenic fluids, special multi-layer insulation is provided for the tanks and other structures.

The development of the cryogenic stage was led by Liquid Propulsion Systems Centre (LPSC) with support from various System Development Agencies from other ISRO Centres of ISRO, viz., Vikram Sarabhai Space Centre (VSSC), ISRO Propulsion Complex (IPRC) and Sathish Dhawan Space Centre (SDSC), SHAR.

The Cryogenic Stage development tests were carried out in two phases.  First, the Stage was subjected to fluid mock-up, wherein the stage preparation and servicing at launch complex in SDSC, SHAR, Shriharikota was completed to prove all the ground facilities established for servicing the cryogenic stage. This was followed by testing of the Stage at ISRO Propulsion Complex, Mahendragiri. From the Stage realisation to completion of testing was accomplished in four months.

The performance of the Stage during the hot test was as predicted. Successful hot test for flight duration qualifies the design of the stage and the robustness of the facilities conceived and established towards its development.

The flight cryogenic stage is in advanced stage of realisation, and forms the upper stage of GSLV MkIII the next generation launch vehicle of ISRO, capable of launching 4 ton class satellites into Geosynchronous Transfer Orbit (GTO). The vehicle consists of two solid strap-ons (S200) motors, one earth storable liquid core stage (L110) and the Cryogenic Upper Stage (C25).

The GSLV MkIII vehicle integration activities are in progress at SDSC, SHAR for its first development flight (GSLV MkIII-D1) targeted for April 2017.

The GSLV Mark-III’s CE-20 cryogenic engine and C25 cryogenic stage, on the other hand, are based on a wholly Indian design that is considerably simpler, though a bit less efficient in terms of propellant consumption, than the CUS. Moreover, the CE-20, producing, as its name suggests, 20 tonnes of thrust, is two and a half times more powerful than the CUS engine. It also ranks, according to ISRO, as one of the most powerful upper stage cryogenic engines in the world. Experience with the CUS had greatly aided development of the Mark-III’s cryogenic engine and stage, remarked S. Somanath, director of the Liquid Propulsion Systems Centre (LPSC).
Quote
Some elements of the CUS engine and its manufacturing process had, for instance, gone into the Mark-III’s CE-20 engine. Stage development, too, had benefited. In the case of the GSLV, after the Russian engine was indigenised and qualified, a flightworthy CUS took eight years to develop, he pointed out. But for the Mark-III, “the [cryogenic] engine was qualified just six months back and we have tested the stage now,” he said.
Quote
The successful completion of all ground tests means the CE-20 engine and the C25 are now ready to take wing.  Assembly of the cryogenic stage for the Mark-III’s first development flight is in progress, according to P.V. Venkitakrishnan, the IPRC director. The stage would be ready for transportation to Sriharikota by the middle of March.
Quote
ISRO flight tested the GSLV Mark-III on an experimental mission in December 2014, using a dummy cryogenic stage. The mission had been carried out to address a number of important questions about the rocket’s performance in actual flight, according to Somanath, who was the Mark-III project director at the time. He claimed that all those questions are answered. “I think we had a beautiful flight,” he said. Now, “we are sure that all the lower stages are going to perform” and so there was greater confidence in the success of the upcoming mission with the actual cryogenic stage.
Quote
These satellites, weighing between 2.7 tonnes and 3.4 tonnes, went into space aboard Europe’s Ariane rockets. The cost of launching just one of those satellites, the 3.4-tonne GSAT-18 that flew on the Ariane 5 last October, came to Rs 459 crore.
On its forthcoming flight, the GSLV Mark-III will be carrying a 3.3-tonne communication satellite, GSAT-19. The payload capacity of the rocket could be enhanced in various ways to about 4.5 tonnes, according to K. Sivan, director of the Vikram Sarabhai Space Centre.

Note: 1 Crore in Indian system = 10 million

Next, GSLV-MK III

With this innovative mission behind it, ISRO is now looking forward to the maiden lift-off of its gigantic Geosynchronous Satellite Launch Vehicle, the GSLV-Mark III, in the second half of April 2017. It weighs 640 tonnes and is the heaviest and most formidable launch vehicle built by ISRO so far. The three-stage vehicle is 44 metres tall and features an indigenously designed and built cryogenic stage, which will be powered by 25 tonnes of liquid oxygen and liquid hydrogen. The rocket’s configuration comprises two solid strap-on booster stages called S-200, each with a capacity to hold 200 tonnes of solid propellants; a liquid core stage called L-110, which will hold 110 tonnes of liquid propellants; and the cryogenic upper stage called C-25, which uses 25 tonnes of cryogenic propellants.

P.V. Venkitakrishnan, Director, ISRO Propulsion Complex (IPRC), Mahendragiri near Nagercoil, Tamil Nadu, was upbeat on February 17 after the cryogenic stage, C-25, fired for its full flight duration of 640 seconds at the IPRC complex. This is a major milestone before the GSLV-MK III lift-off from Sriharikota. After the successful firing, which began at 5 p.m., Venkitakrishnan told Frontline from Mahendragiri: “This was a qualification test, a stage test. We will analyse the results of the test and if no fine-tuning is required, the flight cryo stage will move to Sriharikota in two weeks and the GSLV-MK III launch will take place in the second half of April. The two strap-on booster stages and the liquid core stage have already reached Sriharikota.”

The GSLV-MK III will put into orbit a communication satellite called GSAT-19E, weighing about 3.2 tonnes and built by ISRO Satellite Centre.

Said Venkitakrishnan: “GSLV-MK III is fully designed and developed in India. It is a 100 per cent Indian product.”

GSLV Mk-III launch could happen only after the GSLV Mk-II launch. GSLV Mk-II carrying SAARC satellite was scheduled for launch this month end, but ISRO Satellite Centre (ISAC) was unable to deliver the satellite within the stipulated time because of technical issues. This forced the ISRO to rework on its launch calendar. Now, the SAARC satellite launch is rescheduled for April end.
