The Milton Keynes firm has been awarded a multimillion-pound contract to develop the west section of the northern Olympic Park.
The soft landscape package, which includes drainage, irrigation and planting, was awarded by main contractor BAM Nuttall and will be followed by the award of the east section within the next fortnight.
Frosts landscape construction director Aidan Lane told HW he was delighted with the contract win, after staff had "worked enormously massive hours to get the bid right".
The firm expects to begin work on the 12- to 14-month job in October/November, coinciding with Hillier's tree-planting scheme, and will have six to 40 staff at the park at any one time.
"We'll come out of it a better company. It is good news for all the guys who worked day and night to get (the tender bid) in," said Lane.
Frosts plans to employ a quantity surveyor, apprentices and a contract manager to fulfil the contract.
The Olympic Delivery Authority (ODA) revealed the news exclusively to HW on Monday (21 September).
ODA project sponsor for parklands and public realm John Hopkins said: "The response of the UK landscape and horticulture industry has been hugely encouraging."
