The V&A Museum, new roads and railway lines, and local healthcare facilities are also included in the updated report.
Infrastructure Secretary Michael Matheson visited the construction site of the new £70 million East Lothian Community Hospital in Haddington to launch the investment publication.
He said: "Over the course of 2018-19, infrastructure projects worth more than £1.4 billion were completed and opened to the public. These include the Aberdeen Western Peripheral Route, the V&A Museum in Dundee, electrification of 100 kilometres of single-track line from Dunblane through Stirling and Alloa and 19 new school projects.

"Looking ahead, the Scottish Government's £5 billion commitment to infrastructure investment in 2019-20 will support 50,000 affordable new homes, delivery of the extension of early learning and childcare, new roads and railways, electric vehicles and delivery of superfast broadband across Scotland.
"As part of this, our pipeline report shows Scottish Government procured projects with a value of almost £3.1 billion are estimated to be in construction across Scotland during 2019-20.
"Building on this success, our commitment to have a National Infrastructure Mission will increase annual infrastructure investment by 1% of current (2017) GDP by the end of the next Parliament, helping to protect and create jobs, and boost growth across the country."
