Lot 3 Construction Site – A31 Highway
Topographic monitoring service for the implementation control and verification of the correct positioning during all phases of assembly and fixing of the structural steel elements constituting the main warping of the new cable-stayed bridge over the river Bacchiglione on the A31 Highway
Project overview
One of the most important infrastructures of the new A31 Highway, known as South Valdastico, is the viaduct over the river Bacchiglione between the municipalities of Longare and Montegalda (within the province of Vicenza).
The design for the crossing of the river Bacchiglione and the ditch Canaletto involved the construction of a nine-span viaduct, three of these spans constituting a 532 meter long cable-stayed bridge with a single 35,5 meter wide deck, including the anchoring side bands, supported by two 40 meters high pillars, 140 meters far from each other.
The main structure, made of steel and concrete, was made in its structural steel elements by CIMOLAI Ltd, based in Pordenone, that commissioned us the topographic monitoring service for the implementation control and verification of the correct positioning during all phases of assembly and fixing of the bridge.
The total costs for the construction of the viaduct, begun by Serenissima Costructions Ltd in February 2009 with the opening of the construction site Lot 3 of South Valdastico, were approximately € 49 million. The completion of the work and the debut of this new South Valdastico section, extending from the interconnection between A4 and A31 at the East side of Vicenza to the exit at Montegaldella – Longare was inaugurated on September 22, 2012.
Our service
Our work developed through the initial drawing of a precision closed polygon for the surveying of the reference cornerstones in order to determine the local absolute coordinate system. The latter, also called bridge system, combined with the reference system of the executive design, identified by the theoretical coordinates, would then allow us to control the deviations in X, Y and Z of each structural element in the assembly phase, with respect to its corresponding position within the project.
After this first phase, we proceeded with marking reference targets in correspondence to pre-known points, directly in the structural elements related to the main girders of the bridge. Comparing the surveyed coordinates with the project ones, we checked and correctly positioned each segment constituting the main warping of the bridge deck. Once the guys of the pillars were connected, we checked the correct values of tensioning of the entire structure.

Architectural survey and inventory service of the hospital building, aiming at carrying out a census of the interior and exterior finishing with particular regard to the dimensional, technological and material characteristics of the structure and of the single units of the complex
Project overview
In September 2009 we won the public procurement contract for the surveying and inventory of the Multipurpose Service Centre at the Civil Hospital in Sandrigo, assigned by the Technical and Asset Service for Plants and Logistics of the Local Social and Healthcare Unit (ULSS) of Vicenza. The aim was to take an inventory of the hospital building, through the geometric and construction survey of the structure and the adjacent lot. The service also included the surveying of the interior and exterior finishing with particular regard to the dimensional, technological and material characteristics of the complex and of its single units.
Our service
The surveying of an elaborate building such as the Sandrigo Hospital has pushed us to test and experiment the potentialities of the integration between different kinds of information (graphic, geometric, descriptive and alphanumeric), thus allowing a strongly computerized management, with the use of CAD software and external DB (relational databases) joined together.
Thus we consider this one our “pilot project” for the implementation of BIM in our company, starting from the surveying activity.
The topographical and architectural surveying and the inventory of the hospital building concerned in particular:
| Total Internal Area of the Building | 10,330 mq |
| Total Surveyed Area | 6,38 ha |
| Surveyed Openings | 686 |
| Exterior Doors and Windows | 753 |
| Exterior Doors and Windows Types | 102 |
| Interior Doors and Windows | 721 |
| Interior Doors and Windows Types | 115 |
The work was completed successfully, inspiring new initiatives by our client, who wants to continue this survey and inventory activities in order to increase the knowledge of the real estate managed by the Local Social and Healthcare Unit (ULSS) of Vicenza.

Execution Plan: Carl Bro AS / Consulting Engineers and Planners | Glostrup (Denmark)
Executive Company: MALTAURO-SPENCON-STIRLING JV Ltd
Development of a topographic survey of the road alignment between the town of Ubungo and Marine Port for a total length of about 16 km.
Sequence of major surveying operations we carried out:
- Network densification of benchmarks
- Implementation of a closed levelling line on set benchmarks
- Setting of the centre line and surveying of the roadway in sections, including intersections and civil works
- Design and development of the execution plan
Project overview
Our field survey in Dar Es Salaam (Republic of Tanzania) concerned the urban road section of Mandela Road, one of the main arterial thoroughfares between the urban area of Ubungo and the commercial area of Marine Port, for a total length of about 16 km.
The main project involved rehabilitation works on the existing thoroughfare, that can be summed up in 2 steps:
- Rebuilding of the main road in its 2 two-lane carriageways, including the restoration of all central and lateral curbs along the entire street; reconstruction of the road junctions at crossroads and side roads; vertical realignment of the road near railway crossings and causeways; reconstruction and recovery of the stormwater draining ditch between the main road and the side roads
- Building of a coplanar road for each of the ways for a total length of the project and construction of a new stormwater draining ditch between the existing road and the new service roads
Our service
The sequence of the surveying operations was the following:
- Monitoring and verification of the existing benchmarks; densification of the network with new benchmarks
- Determination and calculation of the closed levelling line on the set benchmarks
- Setting of the centre line and consequent surveying of ground and roadway in sections, including bridges, railway crossings and other civil works
- Drawing of plans, longitudinal profiles and sections for the subsequent estimate of earth moving needs and the control of the execution plan
