Where we work
Construction administration for Texas land development
Construction administration for Texas water, sewer and site work: submittal review, RFIs, site visits, test records and as-builts. Talk to MES.
What we do in Texas
Construction administration for Texas land development
MES stays on Texas projects after the plans are approved. We review submittals and shop drawings, answer contractor RFIs and visit the site at key points.
We also review pay applications and change orders, and we close the job out with as-built drawings and the records owners and regulators ask for.
What Texas rules ask for during construction
Water mains. TCEQ rules in 30 TAC 290.44 require new mains to be disinfected under AWWA standard C651, then flushed and sampled before they go into service. Leakage must stay within AWWA limits.
Completion notice. When public water system work is done, the engineer or owner must tell TCEQ in writing that the work substantially matches the approved plans and change orders.
Gravity sewers. Under 30 TAC 217.57, gravity pipe gets an infiltration or exfiltration test, or a low-pressure air test. Flexible pipe also gets a deflection test, and deflection may not exceed 5%.
Manholes. Under 30 TAC 217.58, each manhole gets a leakage test before backfill, by hydrostatic or vacuum testing.
Cities, utility districts and TxDOT often add their own inspections on top of these.
Construction work in Texas
Near Sweetwater, we provided on-site engineering while four miles of waterline moved clear of TxDOT work on IH-20. We reviewed shop drawings, wrote field reports, prepared the TxDOT payment requests and delivered as-built drawings. Customers kept water service through the work.
In Milford, we provided site construction services during the install of a 15,000 gallon per day RV park lift station, and later prepared its as-built drawings.
Common questions
Does the design engineer have to do construction administration?
No. But the engineer who designed the job knows why each detail is there, which helps when answering RFIs and reviewing submittals.
What tests do Texas gravity sewers need?
An infiltration, exfiltration or low-pressure air test under 30 TAC 217.57. Flexible pipe under 27 inches also gets a rigid mandrel deflection test. Manholes get a leakage test under 217.58.
Can MES scale the level of field support?
Yes. Some jobs need regular site visits. Others need submittal review and milestone visits. Call (214) 833-6748 to talk through yours.
