By the beginning of the 1970s, all eleven TEV-2 production facilities were situated at Lagedi:

• Workshop (finished in 1963, 380 m2)
• Public building (1961, 180 m2)
• Boiler plant (1961, 156 m2)
• Pumping station for industrial and drinking water (1961)
• Bitumen storage (1965, capacity – 1,800 tons of bitumen)
• Transformer substation (1967, 15 m2)
• Weighing facility (1967, 184 m2)
• Wooden warehouse (1967, 334 m2)
• Filler line operator facility with compressor room (1967, 360 m2)
• Technical equipment storage facility (1970, 439 m2)
• Warehouse (1972, 438 m2)

In addition to the aforesaid facilities, residential building no. 1 with 16 apartments (1964, total area 636 m2), buildings no. 2 and 3 (1965 and 1969), pumping station for drinking water (1965), administrative building that was used as a dormitory and woodsheds (1972) were situated at Lagedi. In 1972, TEV-2 commissioned the usage of the Änni (5.56 ha), Raudoja (38.47 ha) and Tammemäe (14.52 ha) quarries.

However, the company with its rapid technological development required the construction of an industrial base that met modern requirements. In 1966, the company was transferred to category II that gave rise to an improved perspective for further substantive development in addition to some structural changes. One of the respective outputs was the plan for constructing a new base for the company in Vana-Pääsküla.

The decision to commence the construction of the base was made in 1968. In 1973, RPI Eesti Tööstusprojekt prepared the construction project for the first stage of the Pärnu mnt 463 industrial base. The development and construction of the TREV-2 industrial base commenced.

In the spring of 1978, the administrative division of the company moved from the small and confined Tulika headquarters to the new building constructed in Vana-Pääsküla. The site of the headquarters of TREV-2 has remained there ever since.

In 1979, the Design Institute EKE Projekt prepared the plan/outline for the second stage of the Pääsküla industrial base and the technical project for the engineering block.

1966-1967 – reconstruction work on Nõmme tee and Haabersti tee.

1961-1972 – extensive construction work on the Tallinn-Pärnu highway 12.4-64 km section, i.e. up to Märjamaa.

1966-1972 – major work on the Ääsmäe-Risti section of Haapsalu highway.

1972-1975 – construction work continued on the Narva highway 12.2-32.3 km section. The work comprised the construction of a new formation. In the course of the work, the concrete cover laid by German prisoners of war in the end of the 1940s was replaced with asphalt.

1972-1976 – construction of the Tallinn ring road (38.4 km), which was one of the most important road construction projects at the beginning of the 1970s. This project held another essential aspect in addition to decreasing traffic loads in Tallinn – the construction of the Tallinn ring road brought about the planned and regular construction of bypass roads for Estonian towns.

1974-1976 – reconstruction work on the Tallinn-Tartu highway 5.3-25 km section.

1974-1980 – extensive construction and reconstruction work on Pirita tee, Merivälja tee and Ranna tee, Pirita bypass and Laagna tee.

1976-1981 – construction work on the Tallinn-Narva highway 36.5-60.2 km section.

By 1972, the mixers of the Lagedi asphalt concrete plant were equipped with D-597 dust collector devices. Control measurements that were conducted later indicated that upon the production of porous asphalt mixtures (coated crushed stone, binder), the new equipment allowed reducing air pollution to the levels permitted by sanitary requirements.

As of 1977, automated control systems with slide moulds were used for producing and laying asphalt and casting kerbstones.
