In 1966, Mr Or Kim Peow established Or Kim Peow Contractor, a sole-proprietorship engaged in civil engineering activities. The PWD was its first customer and the work scope for PWD involved upgrading of mud tracks in the rural parts of Singapore to asphalt roads. The contract value of each of these upgrading projects was generally less than $50,000.
On 26 August 1977, OKP was incorporated as an exempt private company to take over the business of the sole-proprietorship.
Following its incorporation, OKP began to undertake a wider scope of civil engineering and infrastructure construction activities including the construction of urban and arterial roads, expressways, vehicular bridges and flyovers as well as the maintenance of roads and road related facilities.
In 1980, OKP was awarded a contract to widen and improve road condition on Jalan Buroh Road and Jurong Pier Circus Road, with a contract value of approximately $7.4 million. Upon completion of the project in March 1982, OKP secured a contract for a road widening and improvement project along Holland Road with a contract value of approximately $9.8 million.
In 1992, OKP was awarded its first flyover project with a contract value of approximately $17.3 million. PWD continued to be OKP's main customer until 1995 when the Roads and Transportation Division of the PWD merged with three other public sector entities of the then Ministry of Communications, namely Registry of Vehicles, Mass Rapid Transit Corporation and Land Transport Division, to form the LTA. Since then, LTA has been OKP's main customer.
In 1989, OKP received a G4 grading from Construction Industry Development Board (presently known as BCA) in civil engineering. It was upgraded to G6 in 1992 and G7 in 1996. The G7 grading enabled OKP to tender for public projects with contract values of up to $50 million each. In the same year, OKP was awarded the ISO 9002 certification by the CIDB-PSB Certification Board. Under the revised CRS, with effect from 1 July 2002, OKP is graded as an A2 civil engineering contractor and is able to tender for public projects with contract values of up to $65 million each. In July 2002, OKP received the ISO 14000 and OHSAS 18000 certifications from BCA.

In 1983, Mr Oh Enc Nam, together with Mr Oh Kim Poy, established Enc Nam Contractors & Company, a partnership engaged in road construction and road maintenance activities, after having worked for OKP for six years. Road maintenance work consists of re-construction work performed on roads, road reserves, pavements, footpaths and kerbs, guardrails, railings, drains, signboards as well as bus bays and shelters. The partnership was initially established to undertake road construction and road maintenance projects sub-contracted from OKP.
On 24 November 1992, EL was incorporated as an exempt private company to take over the business of the partnership. In 1995, EL was awarded a road widening project along Middle Road between Selegie Road and North Bridge Road, with a contract value of approximately $1.5 million.
In 1992, EL was registered as a G1 civil engineering contractor. It was upgraded to G3 in 1993, G5 in 1995 and G6 in 1998. The G6 grading enabled EL to tender for public projects with contract values of up to $30 million each. EL's main customers are LTA, ENV, JTC and PUB. In 1997, EL was awarded a one-year road maintenance project for the North and Urban Central Division with a contract value of approximately $15.6 million. Over the last three years, EL had successfully completed four major projects, with an aggregate contract value of approximately $5.8 million, relating to roadside drain improvement works awarded by ENV and JTC.
In 1998, EL was awarded ISO 9002 certification by CIDB.
Under the revised CRS, with effect from 1 July 2002, EL is graded as a B2 civil engineering contractor and is able to tender for public projects with contract values of up to $10 million each.
In July 2002, EL received the ISO 14000 and OHSAS 18000 certifications from BCA.
