Explanation
BACKGROUND: The original contract provided for the design and preparation of contract documents for electrical renovation of the Dublin Road Water Plant Auxiliary High Service Pump Station. This modification provides for additions and changes to the scope of work due to field conditions encountered during construction. These include a cone valve control circuit renewal, pump motor leads, dresser couplings, ventilation system rehabilitation, heating system rehabilitation, heating system circulation fan, and SCADA and pump control logic modifications.
In bringing the building systems back online with the new electrical system, it was discovered that the existing ventilation system on the roof was inoperative and not in accordance with current code. The lower level louvers were without automatic operators so that the roof mounted exhaust fans would draw against a closed room unless the lower louvers were left open all the time. A new design and change order was prepared by the consultant, along with inspection, documentation, testing, and training.
While performing high elevation work during the winter, the contractor observed that the furnace heated air was stagnating at ceiling level. The conduits at upper heights were running hot, while the equipment at floor level was quite cold. An air circulating fan, appropriate to bring the hot air pooling at the ceiling down to floor level, and compatible with maintaining freedom of overhead crane movement, was designed and a change order prepared by the consultant, along with inspection, documentation, testing, and training.

2. The extent of additional services could not be initially foreseen due to field conditions discovered during construction.
3. The work under this contract modification is a continuation of work previously performed by the Consultant, therefore, no other processes were used for procurement of these services.
