Hydronic Services

Every stage, from scope to turnover

Each service answers four questions: what we do, when we become involved, what we bring to the site, and what the contractor receives. Work is planned and executed to the approved project specifications, system requirements, equipment limitations and the water-treatment specialist's approved treatment plan.

Stage 1 · Before the Bid or Mobilization

Pre-Construction Planning

Drawing and specification review; take-off review when available; system volume assumptions; flow and equipment planning; chemistry and waste estimates; budget scope; preliminary schedule. Estimators get a defensible flushing allowance; project managers get an execution plan before the first hose arrives on site.

Stage 2 · New Systems

Precommissioning Flushing

Flush-zone planning; temporary pumping sized by hydraulic calculation; filtration; branch and riser sequencing; strainer monitoring; debris removal; and measured flow verification at multiple points across different pipe sizes simultaneously. Pressure testing support where included in the scope.

Stage 2 · Chemical Cleaning

Chemical Cleaning

A defined cleaning process with its own procedure: project-specific chemistry based on system materials and contaminants; chemical circulation and control; rinsing and neutralization; acceptance checks; and wastewater and disposal planning. Chemical cleaning removes construction residues, oils, flux, corrosion products, scale and other deposits from system surfaces.

Stage 2 · After Cleaning, Before Disinfection

Water Treatment Services

Water treatment conditions and protects the system water after cleaning or filling, so the required water-quality baseline can be established. It is delivered jointly with a qualified water-treatment specialist, and each party's scope stays clear:

Specialist scope

System-water review, chemical selection and supply, concentration targets, test methods and acceptance criteria — from a qualified provider such as Chem-Aqua, Nalco Water, or the contractor's or owner's approved firm.

Cleanhydronics scope

Temporary equipment, on-site chemical receiving and handling, dosing, circulation, sampling support, field readings, and the execution and turnover records.

Chemical cleaning and water treatment are often recommended on the same project, but each keeps a separate scope, price and set of deliverables.

Where Included in Mechanical Scope

Potable-Water Disinfection

Approved disinfection procedure; concentration and contact-time controls; sampling coordination; results and records — meeting the regulatory requirements that apply to the project.

Stage 3 · Turnover

Closeout Documentation

The approved method, field logs, flow and condition records, water-test results, exceptions and completion report as included in scope — organized for the commissioning agent, engineer and owner. The flush isn't finished until the paperwork proves it.
