About this file

Written by GovTribe AI · Apr 3, 2024

This document is a bid package for a mechanical HVAC renovation project for the Clare-Gladwin Day School in Clare, Michigan. The project involves the replacement of an existing air handling unit (AHU) with a new AHU-1 unit and installation of a new air-cooled condensing unit (ACCU-1). The mechanical scope also includes modifying and connecting existing ductwork, piping, and controls to the new equipment. The electrical scope includes demolition of the existing AHU power and controls, and installation of new power and controls for the AHU-1 and ACCU-1. The project is scheduled for completion by February 1, 2024.

The bid package provides detailed specifications and drawings for the mechanical and electrical work. It specifies the use of particular manufacturers and models for the AHU and condensing unit. Pricing is not provided, but the bid package directs bidders to provide add/deduct pricing for any substitutions to the specified equipment. The project will be awarded based on the base bid price. No specific funding sources or set-asides are mentioned. The project will be subject to prevailing wage requirements and the contractor must obtain all necessary permits and inspections.

GENERAL MECHANICAL NOTES

1. THE MECHANICAL TRADES SHALL FAMILIARIZE THEMSELVES WITH ALL

EXISTING AND NEW CONDITIONS, THESE DRAWINGS, ADDENDA & RELATED

SPECIFICATIONS. THEY SHALL COMPLETELY SATISFY THEMSELVES AS TO THE

CONDITIONS TO WHICH THE WORK IS TO BE PERFORMED BEFORE SUBMITTING

THEIR BID. NO ALLOWANCES OR CONSIDERATIONS WILL BE GIVEN AT A LATER

NATURE OF THIS PROJECT SITE DUE TO NEGLECT ON THE BIDDERS PART TO

MAKE SUCH AN EXAMINATION AND COORDINATION.

2. DRAWINGS ARE DIAGRAMMATIC AND ARE INTENDED TO SHOW APPROXIMATE

LOCATION AND GENERAL ARRANGEMENT OF SYSTEMS AND EQUIPMENT.

DRAWINGS SHALL NOT BE SCALED FOR LOCATION OF SYSTEMS, EQUIPMENT,

ETC. ALL LOCATIONS OF SYSTEMS AND EQUIPMENT SHALL BE VERIFIED IN

FIELD AND COORDINATED WITH ALL OTHER TRADES AND EXISTING FIELD

CONDITIONS. SOME SYSTEMS (PIPING, DUCTWORK, ETC.) AND EQUIPMENT

LOCATIONS MAY REQUIRE CHANGES IN LOCATION DUE TO FIELD CONDITIONS

AND COORDINATION WITH OTHER TRADES. THESE CHANGES SHALL BE MADE

WITH NO ADDITIONAL COST TO THE OWNER. FAILURE TO VERIFY AND

COORDINATE WILL BE NO REASON FOR ADDITIONAL COMPENSATION.

3. THE INSTALLATION OF ALL SYSTEMS, EQUIPMENT, ETC., IS SUBJECT TO

CLARIFICATION WITH SUBMITTED SHOP DRAWINGS AND FIELD COORDINATION

REQUIREMENTS. EQUIPMENT OUTLINES SHOWN ON DRAWINGS OR

DIMENSIONED ON DRAWINGS ARE LIMITING DIMENSIONS. ANY EQUIPMENT

THAT REDUCES THE INDICATED CLEARANCES OR EXCEEDS SPECIFIED OR

SCHEDULED EQUIPMENT DIMENSIONS SHALL NOT BE USED.

4. THE MECHANICAL CONTRACTOR SHALL COORDINATE FINAL LOCATION OF ALL

EQUIPMENT WITH PIPING, DUCTWORK, ETC., AT THE TIME OF ROUGH-IN. ALL

WITHIN 18” OF CEILING WITHOUT ANY OBSTRUCTIONS AND SHALL HAVE ALL

SERVICE AND ACCESS SPACES KEPT CLEAR. PERFORM ABOVE CEILING

COORDINATION WITH ALL TRADES.

5. THESE DRAWINGS AND THE ASSOCIATED SPECIFICATIONS ARE INTENDED TO

PROVIDE COMPLETELY FURNISHED, INSTALLED AND OPERATIONAL

MECHANICAL SYSTEM (HEATING, VENTILATING, AIR CONDITIONING, PLUMBING

AND PIPING, ETC.). IF THESE DRAWINGS AND ASSOCIATED SPECIFICATIONS

HAVE INFORMATION OMITTED THAT WOULD NOT ALLOW A COMPLETELY

OPERATIONAL SYSTEM AS IS THE INTENT OF THE ENGINEER, THE BIDDER

SHALL NOTIFY THE ENGINEER A MINIMUM ONE WEEK PRIOR TO THE BID DATE

TO ALLOW FOR ADDENDA. ONCE BIDS HAVE BEEN RECEIVED, THE

CONTRACTOR SHALL BE RESPONSIBLE FOR ALL MATERIAL, LABOR, ETC., TO

FURNISH AND INSTALL A COMPLETELY OPERATIONAL MECHANICAL SYSTEM AS

IS THE INTENT OF THESE DRAWINGS AND ASSOCIATED SPECIFICATION. ALL

EQUIPMENT SHALL BE INSTALLED PER MANUFACTURER'S INSTRUCTIONS. IF

ANY DISCREPANCIES ARE ON DRAWINGS, AS COMPARED TO MANUFACTURER'S

INSTALLATION INSTRUCTIONS, THE CONTRACTOR SHALL NOTIFY THE

ENGINEER AND INSTALL EQUIPMENT AS REQUIRED AT NO ADDITIONAL COST TO

THE PROJECT.

6. THE MECHANICAL TRADES SHALL TAKE OUT ALL PERMITS AND ARRANGE FOR

NECESSARY INSPECTIONS AND SHALL PAY ALL FEES AND COSTS.

7. THE MECHANICAL TRADES SHALL VERIFY AMOUNT OF EXISTING PIPING,

VALVES, DUCTWORK, ETC. TO BE REMOVED OR RELOCATED TO ALLOW FOR

INSTALLATION OF NEW PIPING, DUCTWORK, VALVES, EQUIPMENT, WALLS, ETC.

ALL ABANDONED PIPING, VALVES, ETC., SHALL BE REMOVED.

8. THE MECHANICAL TRADES SHALL COORDINATE ALL WORK WITH OTHER

TRADES AND SHALL COORDINATE ANY SYSTEMS SHUT-DOWN WITH THE

ARCHITECT/ENGINEER AND OWNER.

9. ALL EXISTING EQUIPMENT, PIPING, DUCTWORK, ETC. THAT IS TO BE REMOVED

SHALL REMAIN THE PROPERTY OF THE OWNER. THE CONTRACTOR SHALL

REMOVE AND LOCATE THIS MATERIAL THAT REMAINS THE PROPERTY OF THE

OWNER TO A LOCATION DETERMINED BY THE OWNER SOMEWHERE ON SITE. IF

THE OWNER DOES NOT WANT TO MAINTAIN POSSESSION OF THE REMOVED

MATERIAL, THE CONTRACTOR SHALL BE RESPONSIBLE FOR REMOVING

MATERIAL FROM THE SITE AND DISPOSING OF THIS MATERIAL AS NECESSARY

TO MEET ALL CODES AND REQUIREMENTS AND SHALL PAY ALL COSTS AS

REQUIRED FOR ANY DISPOSAL FEES, INSPECTIONS, PERMITS, ETC.

10. ATTACHMENTS OF MECHANICAL OR ELECTRICAL EQUIPMENT TO STRUCTURAL

MEMBERS ARE THE RESPONSIBILITY OF THE INSTALLING TRADE. STRUCTURAL

MEMBERS SHALL NOT BE FIELD CUT, WELDED OR OTHERWISE MODIFIED

WITHOUT APPROVAL OF THE ARCHITECT/ENGINEER. ATTACHMENT TO STEEL

JOISTS SHALL BE MADE AT PANEL POINTS WHENEVER POSSIBLE. STEEL

JOISTS SHALL BE REINFORCED FOR NON-PANEL POINT CONCENTRATED LOADS

IN ACCORDANCE WITH THE STRUCTURAL DETAILS; THIS WORK SHALL BE

PERFORMED BY CERTIFIED WELDERS AND IS THE RESPONSIBILITY OF THE

TRADE INSTALLING THE SUBJECT LOAD. STRUCTURAL MEMBERS SHALL NOT

BE OVERLOADED AS A RESULT OF ATTACHMENTS. ATTACHMENT/EQUIPMENT

LOADING FOR ALL TRADES RESULTING IN TOTAL LOAD GREATER THAN AN

EQUIVALENT UNIFORM 5 PSF FOR ANY MEMBER SHALL BE SUBMITTED TO THE

ARCHITECT/ENGINEER FOR REVIEW.

11. THE MECHANICAL TRADES SHALL FURNISH AND LOCATE CEILING AND/OR WALL

ACCESS DOORS AS REQUIRED TO GIVE ACCESS TO VALVES, EQUIPMENT, ETC.

COORDINATE WALL OR CEILING FIRE RATINGS AND FURNISH ACCESS DOOR

WITH RATING AS NECESSARY. THE GENERAL TRADES SHALL INSTALL ACCESS

DOORS.

12. FURNISH PREFABRICATED ROOF CURB FOR EACH EXHAUST FAN, WITH HEIGHT

OF CURB TO GIVE MINIMUM 12” CLEAR FROM FINISHED ROOF TO EXHAUST FAN

CURB CAP. THE MECHANICAL TRADE SHALL FURNISH THE ROOF CURB TO THE

GENERAL TRADE. THE GENERAL TRADE SHALL LEVEL CURB, PERFORM ALL

ROOFING AND FLASHING ETC.

13. SEE SPECIFICATION FOR FURTHER INFORMATION.

SPECIFIED AND SCHEDULED EQUIPMENT NOTE

EQUIPMENT MANUFACTURERS AND MATERIALS SPECIFIED OR SCHEDULED ON

THESE PROJECT DRAWINGS AND SPECIFICATIONS SHALL BE INCLUDED UNDER THE

BASE BID PRICE. SUBSTITUTE OR ALTERNATE EQUIPMENT SHALL BE PRICED AS AN

ADD OR DEDUCT PRICE TO THE CONTRACTOR'S BASE BID PRICE. IF ONE OR MORE

SUBSTITUTIONS ARE ACCEPTED WITH THE PROPOSAL AT THE CORRESPONDING
