20 SEPARATE CONTRACTS
The Authority reserves the right to enter into other contracts in connection with the undertaking of which the work is a part and the Contractor shall connect properly and co-ordinate his/her work with that of other contractors. If any part of the Contractor's work depends for its proper execution or result upon the work of another contractor, the Contractor shall report promptly to the Project Manager any defects in the work of such other contractor as may interfere with the proper execution of the Contractor's work. Should the Contractor fail so to inspect and report he/she shall have no claim against the Authority except as to latent defects not reasonably noticeable at the time of the commencement of the Contractor's work.
21 CLAIMS AGAINST CONTRACTOR
The Contractor shall promptly pay for all labour, services and materials, in connection with his/her work. All such payments shall be made by the Contractor at least as often as payments are made by the Authority to the Contractor, and, in the event of failure by the Contractor at any time to do so, the Authority may retain from any monies due, or to become due to the Contractor, such an amount of money as the Project Manager may deem sufficient to make such payments. If the Project Manager believes that any such payments will not be promptly made by the Contractor, the Authority may pay for any such labour, services and materials, from any date to any date, and to any amount which may be payable, and the amount or amounts so paid shall be deducted from any monies that may be due or that thereafter may become due to the contractor.
Before final settlement is made for the work done and the materials furnished under the contract, the Contractor shall produce and furnish evidence satisfactory to the Authority that the said work and all its parts are free and clear from all lawful claims or liens under any law, for labour, workmanship, material or otherwise, and that no claim then exists, in respect to which a claim or lien upon the said work could, or might attach. The Contractor shall indemnify and save harmless the Authority from all liens arising from the labour and services performed, the materials furnished, and otherwise, in relation to the said work.
22 LIENS
The Housing Authority and the Contractor are both bound by the Builders Lien Act.
23 PAYMENTS
Payments equal to percentage stipulated in the agreement of the value of the work done, as valued by the Project Manager, will be made to the Contractor monthly, as the work progresses, on the written Certificate of the Project Manager that the work, for or on account of which the certificate is granted, has been duly executed to his/her satisfaction, and stating the value of such work as computed by him/her, and insurance policies for the project are in force; the said certificate shall be a condition precedent to the right of the Contractor to be paid the said percentage, or any part thereof. No such monthly payment shall be construed to be an acceptance of any defective work or improper materials.
Whenever the work is completed according to the Builders Lien Act and to the plans and specifications and to the satisfaction of the Project Manager, the Authority shall issue the final certificate. The Authority will then pay to the Contractor within 65 days of execution of the final certificate the balance of funds due, excepting such sums as may be lawfully deducted or retained under any of the provisions of the Contract. The written Certificate of the Project Manager certifying to the final completion of the said work to his/her entire satisfaction shall be a condition precedent to the right of the Contractor to receive or to be paid the balance due, or any part thereof. The right is reserved by the Authority to reject the whole or any part of the work, should the said certificate be found to be inconsistent with the terms of the Contract, or otherwise improperly given.
GENERAL CONDITIONS Page 6 of 7
MINOR CONSTRUCTION - BULK SUM
23 PAYMENTS CONT’D
The Project Manager's progress certificates, and the payment of progress estimates based upon the same, shall not be construed as acceptance or approval of the work but only as temporary advances to the Contractor; and he/she shall be bound, notwithstanding such progress estimates, to well and truly complete, finish and hand over in good condition, and to the entire satisfaction of the Project Manager, by the time specified and in accordance with the terms and conditions of the specification, the whole of the work included therein; and all the percentage retained by the Authority shall be retained until the said full and satisfactory completion has been formally certified by the Project Manager.
24 COVID-19 The parties acknowledge that the obligations of each party from time to time to meet certain terms and conditions of this Tender may be impeded by the COVID-19 pandemic (the "Pandemic") and related challenges. The Contractor and the Province agree to act in good faith by making all reasonable accommodations as the circumstances of the Pandemic may require, and each party agrees to exercise reasonable efforts to comply with the terms of this Tender notwithstanding the effects of the Pandemic. No party will require or encourage any person acting on its behalf to violate the terms of any order made pursuant to the Health Protection Act (Nova Scotia), the Emergency Management Act (Nova Scotia) or any other order or directive made pursuant to applicable provincial or Federal legislation in relation to the Pandemic (“Pandemic Orders”), or to perform any act which would place such person at a material risk of contracting the COVID-19 virus.

To Whom It May Concern,
This is to advise that certain building materials used in the construction of apartment buildings, office buildings and homes between the years 1946-1986 may contain asbestos fibres. Asbestos may typically be found in drywall filler, texture coats (stucco), floor tiles, tile adhesive, gaskets, hard board, plaster, ceiling tiles, caulking and seamless flooring. Asbestos can be a hazard if the fibres in the building material are released or separated from the material or become air borne. In order for asbestos fibres to be released from this material, it must be sanded or crumbled into small pieces.
Asbestos is not otherwise poisonous and it does not off-gas any toxic chemicals. Under normal conditions of day-to-day usage, these materials do not pose a risk to occupants, as they are not releasing dust.
As many of the Western Regional Housing Authority buildings were constructed prior to 1986 we are advising that asbestos may be present in the building materials. When properly managed these materials are not a cause for concern.
The following responsibilities fall upon any contractor whose work may results in the disturbance of any asbestos-containing or contaminated materials or surfaces:
1. Before commencing work, ensure all contractors employees and supervisory staffhave been informed as to the presence and approximate location of all asbestos-containing materials that may become subject to disturbance (whether intentional ornot).
2. Before commencement of work; file with the Housing Authority Contract Manager asigned and executed copy of a Contractor’s Notification & Acknowledgement form asprovided at the end of this document.
3. Only workers trained and authorized in Type 1, 2, or 3 asbestos work procedures areassigned to work involving exposure to material containing asbestos.
4. Perform work in such a manner as to avoid the disturbance of any asbestos-containing or contaminated surfaces or materials other than those materialsintentionally contracted to remove, repair, encapsulate or enclose.

Appendix #3 – Contractor’s Notification and Acknowledgement
The Housing Authority has identified the presence of various friable and non-friable asbestos-containing materials as being present throughout properties under its control and administration. For a complete listing of any asbestos-containing or suspect asbestos materials known to be present, refer to the most recent version of the asbestos inventory report maintained on file by the individual Housing Authority office.
Contractors other than abatement contractors must ensure their workers, at a minimum, are provided with asbestos awareness training. Proof of training must be presented to the Housing Authority before commencing work at a site.
An Asbestos Management Plan prepared by the Housing Authority applies to all maintenance and renovation work that may disturb asbestos or suspect asbestos-containing materials in the Workplace. This document states that any disturbance of asbestos-containing materials may only be performed by workers or by an outside contractor who have first received the required training in asbestos-related precautions.
The following is a partial listing of typical activities that will or may disturb known asbestos-containing materials and hence requiring the implementation of Type 1, 2 or 3 asbestos precautions. Any Contractor required to perform any of the following activities and/or similar tasks that may result in the disturbance of a known or suspect asbestos-containing materials must first obtain a signed and authorized Asbestos Work Permit from the Supervisor or designate.
