Weekly Notes:

Monday (7/1) morning I inspected the site and took a number of digital photos of the work progress.

Wednesday (7/3) afternoon I attended the Job Progress meeting and inspected the site.

An airflow-monitoring device in a supply air duct located in the ceiling of the LMC was determined to be subject to condensation. This device should be insulated to match that of the remainder of the supply duct.
Indoor temperature and humidity readings on this day were 72 degrees and 40% respectively.
Exterior masonry and roof repairs will commence next week.
Caulking and repairs have been completed at skylights.
The contractor previously engaged to clean supply air ductwork had cut access holes in interior lined (insulated) ducts. These holes were patched with sheet metal, but the insulation was not replaced. These portions of the ductwork are subject to condensation (as observed on this day). These patch locations should be insulated.
Temporary return air filter housings will be removed this week at the second floor. All dust producing construction activities are now complete.
Only minor construction activities remain to be completed at the interior of the building (Install room signs, replace damaged locker parts, etc.)

Monday (7/8) I participated in a meeting to determine the scope of repairs at exterior masonry walls and the roof.

Where exterior walls terminate at lower roofs there is concern for pooling of water at the base of the air gap, behind the building's face brick. Several courses of brick will be removed to gain access to, and replace the existing flashing per the detail provided by SRI Consultants, Inc.
Weeps in the face brick, which had been plugged with grout, will be replaced.
Roof edges will be built up to provide a positive slope from the building edge to roof drains. Current roof edge flashing will be maintained and capped with new flashing.
Sweeps on doors at the roof will be replaced with rubber gaskets.

Thursday (7/11) afternoon I attended the Job Progress meeting and inspected the site.

Honeywell has replaced damaged/faulty thermostats.
It has been determined that the two mechanical rooms will receive a floor sealer to prevent migration of water from these spaces to occupied rooms below. General Polymer's Epoflex with abrasive finish will be applied to the floors.
Fire alarm certification should be scheduled for the end of this month.
Condensation issues noted on 7/3 have been addressed. Insulation has been added at these sections of supply air ducts.

Friday (7/19) morning I inspected the site and took a number of digital photos of the work progress.

Bleu Masonry has completed approximately 75% of the repairs to flashing behind face brick. This work has been accomplished in accordance with the directive of the School District and SRI Consultants, Inc. Proper care has been taken to protect the roof where this work has been accomplished.
More than 50% of the work has been accomplished to provide a positive slope at the roof edges. This work is being done by Gary Brown Roofing in accordance with conversations with School District.
Progress on interior building work has been steady. It appears that the School District's goal of completing interior work by July 26th will easily be accomplished.
