Construction Administration

Construction administration for Oklahoma land development

MES provides construction administration for water, wastewater and site civil projects in Oklahoma. We help owners get from approved plans to a finished, accepted project.

The work can include bid documents and bidding support, the contract and notice of award, submittal review, answers to contractor questions, construction observation and closeout. When MES also designed the project, the same team stays on through construction.

What Oklahoma agencies expect during construction

An Oklahoma Department of Environmental Quality (ODEQ) construction permit for water or wastewater work comes with conditions. A water line permit, for example, can require written ODEQ approval before any change that affects capacity, flow or operation. It also makes the permit holder responsible for supervision and inspection by competent, qualified people.

Timing matters too. A wastewater construction permit expires if construction does not begin within one year, unless ODEQ grants an extension. Plan bidding and award so work starts in time.

Sites under ODEQ's OKR10 stormwater permit must carry out their stormwater pollution prevention plan for the whole job. Coverage ends with a Notice of Termination after construction is complete and the site reaches final stabilization. ODEQ describes that as permanent vegetation at 70 percent or more of the native background cover, or equal permanent measures such as riprap.

Cities, counties and the utility that will own the system run their own inspections and acceptance steps. We plan testing and records around them.

Work in Oklahoma

In Sasakwa, a small town in Seminole County, MES carried the water storage tank project from design into construction. After the town secured its grant, MES supported bidding, prepared the contract and worked on the notice of award in November 2025. We reviewed the paint submittal in February 2026. The recoating and structural repairs were completed, and MES worked on project closeout in April 2026. See the Sasakwa water tank project.

Common questions

How long is an ODEQ construction permit good for?

A wastewater construction permit expires if construction does not begin within one year of issue, unless ODEQ grants an extension. Water line permits can carry a similar one-year start condition.

When does construction stormwater coverage end?

When construction is complete and the site reaches final stabilization, the operator files a Notice of Termination with ODEQ. Coverage ends once ODEQ processes it.

What does construction administration cover?

It covers the work between approved plans and a closed-out project: bidding, contract award, submittal review, field questions, observation and closeout records.
